 # Beads - AI-Native Issue Tracking
 Welcome to Beads! This repository uses **Beads** for issue tracking - a modern, AI-native tool designed to live directly in your codebase alongside your code.
 ## What is Beads?
 Beads is issue tracking that lives in your repo, making it perfect for AI coding agents and developers who want their issues close to their code. No web UI required - everything works through the CLI and integrates seamlessly with git.
 **Learn more:** [github.com/steveyegge/beads](https://github.com/steveyegge/beads)
 ## Quick Start
 ### Essential Commands
 ```bash
 # Create new issues
 bd create "Add user authentication"
 # View all issues
 bd list
 # View issue details
 bd show <issue-id>
 # Update issue status
 bd update <issue-id> --claim
 bd update <issue-id> --status done
 # Sync with Dolt remote
 bd dolt push
 ```
 ### Working with Issues
 Issues in Beads are:
 - **Git-native**: Stored in Dolt database with version control and branching
 - **AI-friendly**: CLI-first design works perfectly with AI coding agents
 - **Branch-aware**: Issues can follow your branch workflow
 - **Always in sync**: Auto-syncs with your commits
 ## Why Beads?
 ✨ **AI-Native Design**
 - Built specifically for AI-assisted development workflows
 - CLI-first interface works seamlessly with AI coding agents
 - No context switching to web UIs
 🚀 **Developer Focused**
 - Issues live in your repo, right next to your code
 - Works offline, syncs when you push
 - Fast, lightweight, and stays out of your way
 🔧 **Git Integration**
 - Automatic sync with git commits
 - Branch-aware issue tracking
 - Dolt-native three-way merge resolution

 # Beads Configuration File
 # This file configures default behavior for all bd commands in this repository
 # All settings can also be set via environment variables (BD_* prefix)
 # or overridden with command-line flags
 # Issue prefix for this repository (used by bd init)
 # If not set, bd init will auto-detect from directory name
 # Example: issue-prefix: "myproject" creates issues like "myproject-1", "myproject-2", etc.
 # issue-prefix: ""
 # Use no-db mode: JSONL-only, no Dolt database
 # When true, bd will use .beads/issues.jsonl as the source of truth
 # no-db: false
 # Enable JSON output by default
 # json: false
 # Feedback title formatting for mutating commands (create/update/close/dep/edit)
 # 0 = hide titles, N > 0 = truncate to N characters
 # output:
 #   title-length: 255
 # Default actor for audit trails (overridden by BEADS_ACTOR or --actor)
 # actor: ""
 # Export events (audit trail) to .beads/events.jsonl on each flush/sync
 # When enabled, new events are appended incrementally using a high-water mark.
 # Use 'bd export --events' to trigger manually regardless of this setting.
 # events-export: false
 # Multi-repo configuration (experimental - bd-307)
 # Allows hydrating from multiple repositories and routing writes to the correct database
 # repos:
 #   primary: "."  # Primary repo (where this database lives)
 #   additional:   # Additional repos to hydrate from (read-only)
 #     - ~/beads-planning  # Personal planning repo
 #     - ~/work-planning   # Work planning repo
 # JSONL backup (periodic export for off-machine recovery)
 # Auto-enabled when a git remote exists. Override explicitly:
 # backup:
 #   enabled: false     # Disable auto-backup entirely
 #   interval: 15m      # Minimum time between auto-exports
 #   git-push: false    # Disable git push (export locally only)
 #   git-repo: ""       # Separate git repo for backups (default: project repo)
 # Integration settings (access with 'bd config get/set')
 # These are stored in the database, not in this file:
 # - jira.url
 # - jira.project
 # - linear.url
 # - linear.api-key
 # - github.org
 # - github.repo

-## Non-Interactive Shell Commands
+## WHERE TO LOOK
-**ALWAYS use non-interactive flags** with file operations to avoid hanging on confirmation prompts.
+| Task                 | Location                           | Notes                                 |
 | -------------------- | ---------------------------------- | ------------------------------------- |
 | Add package          | `pkgs/<name>/default.nix`          | Register in `pkgs/default.nix`        |
 | Add NixOS module     | `modules/nixos/<name>.nix`         | Import in `modules/nixos/default.nix` |
 | Add HM module        | `modules/home-manager/<category>/` | Category: cli, coding, or root        |
 | Override nixpkgs pkg | `overlays/mods/<name>.nix`         | Import in `overlays/mods/default.nix` |
 | Add dev shell        | `shells/<name>.nix`                | Register in `shells/default.nix`      |
 | Use port management  | `config.m3ta.ports.get "service"`  | Host-specific via `hostOverrides`     |
 | CI/CD workflows      | `.gitea/workflows/<name>.yml`      | Automated package updates (nix-update) |
-Shell commands like `cp`, `mv`, and `rm` may be aliased to include `-i` (interactive) mode on some systems, causing the agent to hang indefinitely waiting for y/n input.
+## CONVENTIONS
-**Use these forms instead:**
+**Formatter**: `nix fmt` before commit (alejandra)
 ```bash
 # Force overwrite without prompting
 cp -f source dest           # NOT: cp source dest
 mv -f source dest           # NOT: mv source dest
 rm -f file                  # NOT: rm file
-# For recursive operations
+**Naming**:
-rm -rf directory            # NOT: rm -r directory
+
-cp -rf source dest          # NOT: cp -r source dest
+- Packages: `lowercase-hyphen` (e.g., `hyprpaper-random`)
 - Variables: `camelCase` (e.g., `portHelpers`)
 - Module options: `m3ta.*` namespace
 **Imports**: Multi-line, trailing commas:
 ```nix
 {
  lib,
  stdenv,
  fetchFromGitHub,
 }:
 ```
-**Other commands that may prompt:**
+**Modules**: Standard pattern:
 - `scp` - use `-o BatchMode=yes` for non-interactive
 - `ssh` - use `-o BatchMode=yes` to fail instead of prompting
 - `apt-get` - use `-y` flag
 - `brew` - use `HOMEBREW_NO_AUTO_UPDATE=1` env var

-### Rules
+**Meta**: Always include all fields:
- Use `bd` for ALL task tracking — do NOT use TodoWrite, TaskCreate, or markdown TODO lists
+```nix
- Run `bd prime` for detailed command reference and session close protocol
+meta = with lib; {
- Use `bd remember` for persistent knowledge — do NOT use MEMORY.md files
+  description = "...";
  homepage = "...";
  license = licenses.mit;
  platforms = platforms.linux;
  mainProgram = "...";
 };
 ```
-## Session Completion
+## PACKAGE PATTERNS
-**When ending a work session**, you MUST complete ALL steps below. Work is NOT complete until `git push` succeeds.
+**Rust**: `rustPlatform.buildRustPackage rec { cargoLock.lockFile = src + "/Cargo.lock"; }`
-**MANDATORY WORKFLOW:**
+**Shell**: `writeShellScriptBin "name" ''script''` or `mkDerivation` with custom `installPhase`
-1. **File issues for remaining work** - Create issues for anything that needs follow-up
+**AppImage**: `appimageTools.wrapType2 { ... }`
 2. **Run quality gates** (if code changed) - Tests, linters, builds
 3. **Update issue status** - Close finished work, update in-progress items
 4. **PUSH TO REMOTE** - This is MANDATORY:
   ```bash
   git pull --rebase
   bd dolt push
   git push
   git status  # MUST show "up to date with origin"
   ```
 5. **Clean up** - Clear stashes, prune remote branches
 6. **Verify** - All changes committed AND pushed
 7. **Hand off** - Provide context for next session
-**CRITICAL RULES:**
+**Custom fetcher**: `fetchFromGitea { domain = "code.m3ta.dev"; owner = "m3tam3re"; ... }`
- Work is NOT complete until `git push` succeeds
+
- NEVER stop before pushing - that leaves work stranded locally
+## MODULE PATTERNS
- NEVER say "ready to push when you are" - YOU must push
+
- If push fails, resolve and retry until it succeeds
+**Simple**: `options.cli.name = { enable = mkEnableOption "..."; }; config = mkIf cfg.enable { ... };`
-<!-- END BEADS INTEGRATION -->
+
 **Multiple**: `config = mkMerge [ (mkIf cfg.x.enable { ... }) (mkIf cfg.y.enable { ... }) ];`
 **Shared lib**: `portsLib = import ../../lib/ports.nix { inherit lib; }; portHelpers = portsLib.mkPortHelpers { ... };`
 ## LIBRARY FUNCTIONS
 ### `lib.ports`
 Port management utilities. See [Port Management](#port-management).
 ### `lib.agents`
 Harness-agnostic agent management. Reads canonical `agent.toml` +
 `system-prompt.md` from the AGENTS flake input and renders tool-specific configs.
 **Functions:**
 | Function | Purpose |
 |----------|--------|
 | `loadCanonical { agentsInput }` | Load canonical agents from AGENTS flake |
 | `renderForOpencode { pkgs, canonical, modelOverrides }` | Render to OpenCode file-based agents |
 | `renderForClaudeCode { pkgs, canonical, modelOverrides }` | Render to Claude Code agents + settings.json |
 | `renderForPi { pkgs, canonical, modelOverrides, primaryAgent }` | Render to Pi AGENTS.md + SYSTEM.md + agents/ |
 | `renderForTool { pkgs, agentsInput, tool, modelOverrides }` | Dispatch to correct renderer by tool name |
 | `shellHookForTool { pkgs, agentsInput, tool, modelOverrides }` | Generate devShell shellHook (symlinks rendered files) |
 ### `lib.coding-rules`
 Coding rules injection. Generates `coding-rules.json` + symlinks rules from
 the AGENTS repository. The old `lib.opencode-rules` name still works.
 | Function | Purpose |
 |----------|--------|
 | `mkCodingRules { agents, languages, concerns, frameworks, rulesDir }` | Generate rules config + shellHook. `rulesDir` defaults to `.opencode-rules` |
 | `mkOpencodeRules` | Backward-compat alias for `mkCodingRules` |
 ## PORT MANAGEMENT
 Central port management: `config.m3ta.ports.get "service"` with host-specific via `hostOverrides`
 Generated: `/etc/m3ta/ports.json` (NixOS), `~/.config/m3ta/ports.json` (HM)
 ## COMMANDS
 ```bash
 nix flake check              # Validate flake
 nix fmt                      # Format (alejandra)
 nix build .#<pkg>            # Build package
 nix flake show               # List outputs
 nix develop                  # Enter dev shell
 nix develop .#python         # Python shell
 nix develop .#devops         # DevOps shell
 # In dev shell only:
 statix check .               # Lint
 deadnix .                    # Find dead code
 ```
 ## ANTI-PATTERNS
 | Don't                     | Do Instead                                                          |
 | ------------------------- | ------------------------------------------------------------------- |
 | `lib.fakeHash` in commits | Get real hash: `nix build`, copy from error                         |
 | Flat module files         | Organize by category (`cli/`, `coding/`)                            |
 | Hardcode ports            | Use `m3ta.ports` module                                             |
 | Skip meta fields          | Include all: description, homepage, license, platforms, mainProgram |
 | `with pkgs;` in modules   | Explicit `pkgs.package` or `with pkgs; [ ... ]` in lists only       |
 ## COMMIT FORMAT
 ```
 type: brief description
 ```
 Types: `feat`, `fix`, `docs`, `style`, `refactor`, `chore`
 ## NOTES
 - **Hash fetching**: Use `lib.fakeHash` initially, build to get real hash
 - **HM modules**: Category subdirs (`cli/`, `coding/`) have own `default.nix` aggregators
 - **Ports module**: Different for NixOS vs HM (HM adds `generateEnvVars` option)
 - **Overlays**: `modifications` overlay uses `{prev}:` pattern, not `{final, prev}:`
 - **Dev shell tools**: `statix`, `deadnix` only available inside `nix develop`
 - **Automated package updates**: Packages are automatically updated weekly via Gitea Actions using `nix-update`. Review PRs from the automation before merging. For urgent updates, manually run the workflow or update manually.
 ## Task Management
 **td** is an optional task-tracking package. See `docs/packages/td.md` for details.
 ## Agent System Architecture
 The agent system uses harness-agnostic canonical definitions stored as
 `agent.toml` + `system-prompt.md` in the AGENTS repository. Renderers in
 `lib/agents.nix` transform these into tool-specific configs at build time.
 ### How it works
 1. **Canonical definitions** live in the AGENTS repo as `agent.toml` files
   (one per agent) with shared fields: name, description, mode, systemPrompt,
   permissions, skills.
 2. **`loadCanonical`** reads all agent definitions from the AGENTS flake input.
 3. **Renderers** produce tool-specific output:
   - `renderForOpencode` → `*.md` files with YAML frontmatter for `.opencode/agents/`
   - `renderForClaudeCode` → `.claude/agents/*.md` + `.claude/settings.json` with permission rules
   - `renderForPi` → `AGENTS.md`, `SYSTEM.md`, `agents/*.md` for Pi's subagent format
 4. **`renderForTool`** dispatches to the correct renderer by tool name
   (`"opencode"`, `"claude-code"`, or `"pi"`).
 5. **`shellHookForTool`** generates a devShell shellHook that symlinks rendered
   files into the project directory.
 6. **HM modules** in `modules/home-manager/coding/agents/` handle per-tool
   Home Manager integration.

 - `modules/home-manager/coding/agents/` — per-tool HM sub-modules (opencode, claude-code, pi)

 # Adding Modules Guide
 How to add new NixOS and Home Manager modules to m3ta-nixpkgs.
 ## Overview
 Modules extend your system or user configuration with reusable, declarative options. m3ta-nixpkgs uses the standard NixOS module system with a `m3ta.*` namespace.
 ## Quick Start
 Use a template for quick setup:
 ```bash
 # NixOS module
 nix flake init -t .#nixos-module my-module
 # Home Manager module
 nix flake init -t .#home-manager-module my-module
 ```
 This copies the template into `templates/` — move it to the appropriate location and customize.
 ## Adding a NixOS Module
 ### 1. Create the Module File
 Create `modules/nixos/<my-module>.nix`:
 ```nix
 {config, lib, pkgs, ...}:
 with lib; let
  cfg = config.m3ta.myModule;
 in {
  options.m3ta.myModule = {
    enable = mkEnableOption "my module description";
    # Add custom options here
    someOption = mkOption {
      type = types.str;
      default = "default-value";
      description = "Description of this option";
    };
  };
  config = mkIf cfg.enable {
    # System configuration goes here
    environment.systemPackages = [pkgs.some-package];
    # Or systemd services
    systemd.services.my-service = {
      enable = true;
      description = "My service";
      wantedBy = ["multi-user.target"];
      serviceConfig = {
        ExecStart = "${pkgs.some-package}/bin/some-daemon";
      };
    };
  };
 }
 ```
 ### 2. Register in the Aggregator
 Add to `modules/nixos/default.nix`:
 ```nix
 {
  imports = [
    ./ports.nix
    ./mem0.nix
    ./<my-module>.nix   # ← add your module
  ];
 }
 ```
 ### 3. Export from flake.nix
 Add to the `nixosModules` output in `flake.nix` (optional, for direct import):
 ```nix
 nixosModules = {
  default = ./modules/nixos;
  ports = ./modules/nixos/ports.nix;
  mem0 = ./modules/nixos/mem0.nix;
  my-module = ./modules/nixos/<my-module>.nix;  # ← add this
 };
 ```
 ## Adding a Home Manager Module
 Home Manager modules are organized by category under `modules/home-manager/`.
 ### Categories
 | Category | Purpose | Location |
 |----------|---------|----------|
 | `cli/` | Command-line tools and utilities | `modules/home-manager/cli/` |
 | `coding/` | Development tools, editors, agents | `modules/home-manager/coding/` |
 | Root | Cross-cutting concerns (e.g., ports) | `modules/home-manager/` |
 ### 1. Choose a Category
 - **CLI tools** (zsh plugins, tmux config, etc.) → `cli/`
 - **Development tools** (editor config, linters, etc.) → `coding/`
 - **System-wide settings** (ports, environment) → root level
 ### 2. Create the Module File
 Create `modules/home-manager/<category>/<my-module>.nix`:
 ```nix
 {config, lib, pkgs, ...}:
 with lib; let
  cfg = config.m3ta.myModule;
 in {
  options.m3ta.myModule = {
    enable = mkEnableOption "my user module description";
    someOption = mkOption {
      type = types.str;
      default = "value";
      description = "An option for this module";
    };
  };
  config = mkIf cfg.enable {
    home.packages = [pkgs.some-package];
    # Or Home Manager-specific options
    programs.zsh.enable = true;
  };
 }
 ```
 ### 3. Register in the Category Aggregator
 For `cli/` modules, add to `modules/home-manager/cli/default.nix`:
 ```nix
 {
  imports = [
    ./rofi-project-opener.nix
    ./stt-ptt.nix
    ./zellij-ps.nix
    ./<my-module>.nix   # ← add your module
  ];
 }
 ```
 For `coding/` modules, add to `modules/home-manager/coding/default.nix`:
 ```nix
 {
  imports = [
    ./editors.nix
    ./opencode.nix
    ./agents
    ./<my-module>.nix   # ← add your module
  ];
 }
 ```
 ### 4. Export from flake.nix
 Add to `homeManagerModules` in `flake.nix`:
 ```nix
 homeManagerModules = {
  default = import ./modules/home-manager;
  my-module = import ./modules/home-manager/<category>/<my-module>.nix;  # ← add this
 };
 ```
 ## Module Patterns
 ### Standard Enable Option
 Always start with `mkEnableOption`:
 ```nix
 options.m3ta.myModule = {
  enable = mkEnableOption "my module";
 };
 ```
 ### Conditional Configuration
 Use `mkIf` for conditional config:
 ```nix
 config = mkIf cfg.enable {
  # Only applied when enabled
 };
 ```
 ### Multiple Conditions
 Use `mkMerge` when combining multiple conditional blocks:
 ```nix
 config = mkMerge [
  (mkIf cfg.feature1.enable { ... })
  (mkIf cfg.feature2.enable { ... })
 ];
 ```
 ### Nested Namespaces
 For logically grouped options, use nested namespaces:
 ```nix
 options.m3ta.coding = {
  myTool = {
    enable = mkEnableOption "my coding tool";
    # ...
  };
 };
 ```
 Usage: `m3ta.coding.myTool.enable = true;`
 ### Shared Library Functions
 For shared utilities (port helpers, etc.), import from `lib/`:
 ```nix
 let
  portsLib = import ../../lib/ports.nix {inherit lib;};
  portHelpers = portsLib.mkPortHelpers { /* ... */ };
 in {
  # use portHelpers
 }
 ```
 ## Documentation
 Add documentation for your module:
 1. Create `docs/modules/nixos/<my-module>.md` (NixOS) or `docs/modules/home-manager/<category>/<my-module>.md` (HM)
 2. Follow the existing format in `docs/modules/`
 3. Add it to the appropriate overview page's "Available Modules" list
 4. Link it from `docs/guides/using-modules.md`
 ## Testing
 ```bash
 # Validate the module loads correctly
 nix flake check
 # Test with a minimal configuration (NixOS)
 nixos-rebuild dry-build -I nixpkgs=. --option experimental-features flakes
 # Format before commit
 nix fmt
 ```

 # Pi Agent Isolation (two-repo setup)
 This guide documents the split setup where:
 - `m3ta-nixpkgs` provides reusable module logic.
 - `nixos-config` consumes it on specific hosts.
 ## 1) In `m3ta-nixpkgs`
 Use:
 - Home Manager module: `coding.agents.pi`
  - renders Pi config in user space (default path: `.pi/agent` => `~/.pi/agent`)
 - NixOS module: `m3ta.pi-agent`
  - dedicated user/group (default `pi-agent`)
  - state directory (default `/var/lib/pi-agent`)
  - hardened execution via transient `systemd-run`
  - host-side wrapper command (default `pi`)
  - per-user allowlists via `hostUsers.<name>.projectRoots`
  - host config sync into isolated runtime (default source `.pi/agent`)
  - managed settings/env merge into isolated runtime
 ## 2) In consumer repo (`nixos-config`)
 ### Home Manager side
 Keep Pi config rendering enabled for your normal user:
 ```nix
 coding.agents.pi = {
  enable = true;
  agentsInput = inputs.agents;
  path = ".pi/agent";
 };
 ```
 ### NixOS host side (example: `m3-kratos`)
 Enable isolated wrapper execution:
 ```nix
 m3ta.pi-agent = {
  enable = true;
  stateDir = "/var/lib/pi-agent";
  hostUsers = {
    m3tam3re = {
      projectRoots = ["~/p" "~/work/private"];
      # optional; defaults to wrapper.hostConfigPath
      configPath = ".pi/agent";
    };
  };
  settings = {
    defaultProvider = "anthropic";
    defaultModel = "anthropic/claude-sonnet-4";
    quietStartup = true;
  };
  environment = {
    PI_TELEMETRY = "0";
  };
  environmentFiles = [
    "/run/secrets/pi-agent.env"
  ];
  wrapper = {
    enable = true;
    commandName = "pi";
    hideDirectBinary = true;
    hostConfigPath = ".pi/agent";
  };
 };
 ```
 ## 3) Authorization model
 The wrapper uses a tightly scoped sudo rule:
 - authorized users may run only the privileged runner command
 - with `NOPASSWD`
 - no broad `NOPASSWD: ALL`
 ## 4) Merge behavior
 At invocation time, isolated runtime files are built from:
 1. Host user Pi config (synced from source path, e.g. `~/.pi/agent`)
 2. Nix-managed settings/env (override host values)
 3. Environment files (appended after managed env attrs)
 This keeps user-authored Pi config available while allowing reproducible Nix overrides.
 ## 5) Migration notes
 - If wrapper mode is canonical, remove direct `pi-coding-agent` from user package lists to reduce command-path ambiguity.
 - Rebuild host config and test from an allowlisted project path.
 - Validate `pi` process identity runs as `pi-agent`.

 # m3ta-nixpkgs: Cleanup & Improvements Plan
 > **For Hermes:** Use subagent-driven-development skill to implement this plan task-by-task.
 **Goal:** Address 10 issues identified in codebase review — reduce duplication, improve naming consistency, extract inline scripts, add testing, and update documentation.
 **Architecture:** Incremental improvements across lib/, modules/, overlays/, docs/, and CI. Each change is self-contained and can be merged independently. No breaking changes to public API (backward-compat aliases preserved where needed).
 **Repo:** `gitea@code.m3ta.dev:m3tam3re/nixpkgs.git` (master branch)
 ---
 ## Phase 1: Deduplication & Naming (Low Risk)
 ### Task 1: Remove duplicate opencode-rules.nix file
 **Objective:** Eliminate the duplicate file import. The `coding-rules.nix` is the canonical source; `opencode-rules.nix` is an identical copy. Make the alias a one-liner in `lib/default.nix`.
 **Files:**
 - Delete: `lib/opencode-rules.nix`
 - Modify: `lib/default.nix`
 **Step 1: Update lib/default.nix to alias directly**
 ```nix
 {lib}: {
  ports = import ./ports.nix {inherit lib;};
  coding-rules = import ./coding-rules.nix {inherit lib;};
  # Backward-compat alias: opencode-rules → coding-rules
  opencode-rules = import ./coding-rules.nix {inherit lib;};
  opencode = import ./coding-rules.nix {inherit lib;};
 }
 ```
 **Step 2: Delete the duplicate file**
 ```bash
 git rm lib/opencode-rules.nix
 ```
 **Step 3: Verify nothing breaks**
 ```bash
 nix flake check
 ```
 **Step 4: Commit**
 ```bash
 git commit -m "refactor: remove duplicate opencode-rules.nix, use alias in default.nix"
 ```
 ---
 ### Task 2: Tool-agnostic naming in coding-rules.nix internals
 **Objective:** Rename internal variables and output artifacts in `coding-rules.nix` from opencode-specific names to generic names, while keeping the backward-compat alias `mkOpencodeRules`.
 **Files:**
 - Modify: `lib/coding-rules.nix`
 **Step 1: Rename internal symbols**
 In `lib/coding-rules.nix`, rename:
 - `rulesDir` stays `.opencode-rules` (this is a filesystem path used by existing projects, changing it would break)
 - `opencodeConfig` → `rulesConfig`
 - `opencode.json` output → `coding-rules.json` (add a comment noting it was renamed)
 - Add `rulesDir` option to function signature with default `.opencode-rules`
 Updated function:
 ```nix
 {lib}: let
  mkCodingRules = {
    agents,
    languages ? [],
    concerns ? [
      "coding-style"
      "naming"
      "documentation"
      "testing"
      "git-workflow"
      "project-structure"
    ],
    frameworks ? [],
    extraInstructions ? [],
    rulesDir ? ".opencode-rules",
  }: let
    instructions =
      (map (c: "${rulesDir}/concerns/${c}.md") concerns)
      ++ (map (l: "${rulesDir}/languages/${l}.md") languages)
      ++ (map (f: "${rulesDir}/frameworks/${f}.md") frameworks)
      ++ extraInstructions;
    rulesConfig = {
      "$schema" = "https://opencode.ai/config.json";
      inherit instructions;
    };
  in {
    inherit instructions;
    shellHook = ''
      # Create/update symlink to AGENTS rules directory
      ln -sfn ${agents}/rules ${rulesDir}
      # Generate coding-rules configuration file
      cat > coding-rules.json <<'RULES_EOF'
      ${builtins.toJSON rulesConfig}
      RULES_EOF
    '';
  };
  # Backward-compat alias
  mkOpencodeRules = mkCodingRules;
 in {
  inherit mkCodingRules mkOpencodeRules;
 };
 ```
 **Step 2: Update shellHook comment in AGENTS.md**
 In `AGENTS.md`, update the coding-rules section to mention the new `rulesDir` parameter and the `coding-rules.json` output file.
 **Step 3: Verify**
 ```bash
 nix flake check
 ```
 **Step 4: Commit**
 ```bash
 git commit -m "refactor: tool-agnostic naming in coding-rules.nix internals"
 ```
 ---
 ### Task 3: Remove redundant overlays entry in flake.nix
 **Objective:** The `default` and `additions` overlays in `flake.nix` produce identical output. Remove `additions` if not referenced elsewhere, or document why both exist.
 **Files:**
 - Modify: `flake.nix`
 - Check: all consumer repos for references to `overlays.additions`
 **Step 1: Search for consumers of overlays.additions**
 ```bash
 # Check nixos-config and other repos
 grep -r "overlays.additions" /data/.hermes/repos/nixos-config/
 grep -r "additions" /data/.hermes/repos/nixos-config/ --include="*.nix" | grep overlay
 ```
 **Step 2: If no consumers found, remove additions**
 In `flake.nix`, simplify overlays to:
 ```nix
 overlays = {
  default = final: prev:
    import ./pkgs {
      pkgs = final;
      inputs = inputs;
    };
  modifications = final: prev: import ./overlays/mods {inherit prev;};
 };
 ```
 **Step 3: Verify**
 ```bash
 nix flake check
 ```
 **Step 4: Commit**
 ```bash
 git commit -m "refactor: remove redundant 'additions' overlay (identical to 'default')"
 ```
 **Note:** If `additions` IS used elsewhere, add a comment explaining the convention and skip this task.
 ---
 ## Phase 2: Extract Inline Scripts (Medium Risk)
 ### Task 4: Extract pi-agent runner script to standalone file
 **Objective:** Move the ~200-line inline bash script in `modules/nixos/pi-agent.nix` (the `runner` variable) to a separate file `modules/nixos/pi-agent-runner.sh` that gets imported via `builtins.readFile` + `pkgs.writeShellApplication`.
 **Files:**
 - Create: `modules/nixos/pi-agent-runner.sh`
 - Modify: `modules/nixos/pi-agent.nix`
 **Step 1: Create the runner script file**
 Extract the body of the `runner` script (everything inside the `pkgs.writeShellScriptBin cfg.wrapper.runnerName '' ... ''`) into `modules/nixos/pi-agent-runner.sh`.
 The script uses Nix-style variable interpolation (`${...}`). We need to keep Nix template variables as `${...}` and convert runtime bash variables to use `$` prefix. Since the script already uses Nix `escapeShellArg` and `escapeShellArg` calls, the cleanest approach is:
 Create `modules/nixos/pi-agent-runner.sh` as a template that `pkgs.substituteAll` or `builtins.readFile` + string replacement can process. However, given the heavy Nix interpolation, the pragmatic approach is to use `pkgs.writeShellApplication` with the script body inline but extracted to a `let` binding:
 ```nix
 # In pi-agent.nix, replace the inline runner with:
 let
  runnerScript = builtins.readFile ./pi-agent-runner.sh;
  # ... or keep as let binding but move the body to a separate derivation
 ```
 **Important caveat:** The script has ~30 Nix variable interpolations (`${cfg.user}`, `${escapeShellArg ...}`, etc.). Full extraction to a .sh file would require either:
 - (a) `substituteAll` with `--replace` for each variable — unwieldy at 30+ substitutions
 - (b) Converting to env vars passed at runtime — cleaner but changes security posture
 - (c) Keeping the Nix interpolation but extracting to a `let` block in a separate `.nix` file
 **Recommended approach: Option (c)** — Create `modules/nixos/pi-agent-runner.nix` as a function that takes `cfg` and returns the script:
 ```nix
 # modules/nixos/pi-agent-runner.nix
 {cfg, pkgs, lib, ...}:
 with lib; let
  # ... all the helper variables from pi-agent.nix ...
 in
  pkgs.writeShellScriptBin cfg.wrapper.runnerName ''
    # ... the script body ...
  '';
 ```
 Then in `pi-agent.nix`:
 ```nix
 runner = import ./pi-agent-runner.nix {inherit cfg pkgs lib;};
 ```
 **Step 2: Similarly extract the wrapper script**
 Create `modules/nixos/pi-agent-wrapper.nix` for the `wrapper` variable.
 **Step 3: Verify**
 ```bash
 nix flake check
 # Also test in a nixos-rebuild if possible
 ```
 **Step 4: Commit**
 ```bash
 git add modules/nixos/pi-agent-runner.nix modules/nixos/pi-agent-wrapper.nix
 git commit -m "refactor: extract pi-agent runner and wrapper to separate files"
 ```
 ---
 ## Phase 3: Testing (Higher Value)
 ### Task 5: Add basic lib function tests
 **Objective:** Add `nix eval`-based tests for `lib/agents.nix` parseRule logic and `lib/coding-rules.nix` instruction generation.
 **Files:**
 - Create: `tests/lib/agents-test.nix`
 - Create: `tests/lib/coding-rules-test.nix`
 - Modify: `flake.nix` (add checks)
 **Step 1: Create test infrastructure**
 ```nix
 # tests/lib/default.nix
 {
  agents = import ./agents-test.nix;
  coding-rules = import ./coding-rules-test.nix;
 }
 ```
 **Step 2: Write agents.nix parseRule test**
 ```nix
 # tests/lib/agents-test.nix
 let
  lib = import <nixpkgs/lib>;
  agentsLib = (import ../../lib {inherit lib;}).agents;
  # Test parseRule helper
  test1 = let
    result = builtins.tryEval (
      let
        # We can't directly test parseRule since it's internal.
        # Instead, test the renderer with minimal input.
        canonical = {
          test-agent = {
            description = "Test agent";
            mode = "primary";
            systemPrompt = "You are a test.";
            permissions = {
              bash = { intent = "allow"; };
              edit = { intent = "ask"; rules = ["rm -rf *:deny"]; };
            };
          };
        };
        pkgs = import <nixpkgs> { system = "x86_64-linux"; };
        rendered = agentsLib.renderForOpencode {
          inherit pkgs canonical;
        };
      in
        # Verify the derivation builds
        builtins.pathExists "${rendered}/test-agent.md"
    );
  in assert result.value == true; true;
 in {
  parseRule-basic = test1;
 }
 ```
 **Step 3: Write coding-rules test**
 ```nix
 # tests/lib/coding-rules-test.nix
 let
  lib = import <nixpkgs/lib>;
  codingRulesLib = (import ../../lib {inherit lib;}).coding-rules;
  rules = codingRulesLib.mkCodingRules {
    agents = "/tmp/fake-agents";
    languages = ["python"];
    concerns = ["naming"];
    rulesDir = ".coding-rules";
  };
  # Verify instructions are generated correctly
  test1 = assert rules.instructions == [
    ".coding-rules/concerns/naming.md"
    ".coding-rules/languages/python.md"
  ]; true;
  # Verify backward-compat alias exists
  test2 = assert codingRulesLib.mkOpencodeRules == codingRulesLib.mkCodingRules; true;
 in {
  instructions-correct = test1;
  backward-compat = test2;
 }
 ```
 **Step 4: Add to flake.nix checks**
 In `flake.nix`, extend the `checks` attribute:
 ```nix
 checks = forAllSystems (system: let
  pkgs = pkgsFor system;
  packages = import ./pkgs {inherit pkgs inputs;};
 in
  builtins.mapAttrs (name: pkg: pkgs.lib.hydraJob pkg) packages
  // {
    formatting = pkgs.runCommand "check-formatting" {} ''
      ${pkgs.alejandra}/bin/alejandra --check ${./.}
      touch $out
    '';
    lib-tests = pkgs.runCommand "lib-tests" {} ''
      ${pkgs.nix}/bin/nix-instantiate --eval ${./tests/lib/default.nix}
      touch $out
    '';
  });
 ```
 **Step 5: Verify**
 ```bash
 nix flake check
 ```
 **Step 6: Commit**
 ```bash
 git add tests/
 git commit -m "test: add basic lib function tests for agents and coding-rules"
 ```

 ### Task 6: Add NixOS VM test for pi-agent module
 **Objective:** Add a basic NixOS VM test that verifies the pi-agent module can be evaluated and the wrapper/runner scripts exist.
 **Files:**
 - Create: `tests/nixos/pi-agent-test.nix`
 - Modify: `flake.nix` (add to checks)
 **Step 1: Write the VM test**
 ```nix
 # tests/nixos/pi-agent-test.nix
 {pkgs, ...}: {
  name = "pi-agent";
  nodes.machine = {config, ...}: {
    imports = [
      ${(pkgs.path + "/nixos/modules/module-list.nix")}
    ];
    # Minimal pi-agent config
    m3ta.pi-agent = {
      enable = true;
      package = pkgs.writeScriptBin "pi-agent" ''
        #!/bin/sh
        echo "pi-agent mock"
      '';
      createUser = true;
      hostUsers = {
        testuser = {
          projectRoots = ["/tmp/test-project"];
        };
      };
    };
    users.users.testuser = {
      isNormalUser = true;
    };
  };
  testScript = ''
    machine.start()
    machine.wait_for_unit("multi-user.target")
    # Verify user was created
    machine.succeed("id pi-agent")
    # Verify wrapper exists
    machine.succeed("which pi")
    # Verify state directory
    machine.succeed("test -d /var/lib/pi-agent")
    machine.succeed("test -d /var/lib/pi-agent/.pi")
  '';
 }
 ```
 **Step 2: Add to flake.nix checks**
 ```nix
 # In the checks attrset:
 pi-agent-vm-test = pkgs.nixosTest (import ./tests/nixos/pi-agent-test.nix {inherit pkgs;});
 ```
 **Step 3: Verify**
 ```bash
 nix build .#checks.x86_64-linux.pi-agent-vm-test
 ```
 **Step 4: Commit**
 ```bash
 git add tests/nixos/
 git commit -m "test: add NixOS VM test for pi-agent module"
 ```
 ---
 ## Phase 4: Documentation (Low Risk, High Value)
 ### Task 7: Update AGENTS.md to reflect current state
 **Objective:** Remove outdated migration sections, update function signatures, and align with current code.
 **Files:**
 - Modify: `AGENTS.md`
 **Step 1: Update the AGENTS REWORK migration section**
 The section starting with `## MIGRATION: Agent System (OpenCode → Canonical TOML)` describes a completed migration. Convert it to a brief "Architecture" section that describes the current state, not the migration path.
 **Step 2: Update lib.agents function table**
 Verify that the function signatures and descriptions in the AGENTS.md table match the actual functions in `lib/agents.nix`. Specifically:
 - `loadCanonical` takes `{agentsInput}` — confirm docs match
 - `renderForPi` now has `primaryAgent` parameter — confirm documented
 - `shellHookForTool` exists — confirm documented
 **Step 3: Update coding-rules documentation**
 Replace references to `mkOpencodeRules` with `mkCodingRules` as primary, `mkOpencodeRules` as backward-compat alias. Document the new `rulesDir` parameter.
 **Step 4: Update overlay documentation**
 Remove or annotate the `additions` overlay depending on Task 3 outcome.
 **Step 5: Commit**
 ```bash
 git commit -m "docs: update AGENTS.md to reflect current codebase state"
 ```
 ---
 ### Task 8: Add CHANGELOG.md
 **Objective:** Create a changelog that captures recent work (from git log) so consumers can track changes.
 **Files:**
 - Create: `CHANGELOG.md`
 **Step 1: Generate changelog from git history**
 ```bash
 cd /data/.hermes/repos/nixpkgs-review
 git log --oneline --no-merges master | head -30
 ```
 **Step 2: Write CHANGELOG.md**
 Structure as Keep a Changelog format:
 ```markdown
 # Changelog
 All notable changes to this project will be documented in this file.
 The format is based on [Keep a Changelog](https://keepachangelog.com/).
 ## [Unreleased]
 ## [0.4.0] - 2026-04-15
 ### Added
 - Pi agent wrapper with per-host-user policy enforcement (`m3ta.pi-agent` NixOS module)
 - `coding.agents.pi` Home Manager module with settings, MCP, and skills support
 - `coding.agents.claude-code` Home Manager module with MCP integration
 - Automated package updates via Gitea Actions (`nix-update` workflow)
 - `lib.agents.renderForPi` with primaryAgent selection and pi-subagents format
 - `pkgs/td` - Task management CLI for AI coding sessions
 ### Changed
 - Renamed `lib.opencode-rules` → `lib.coding-rules` (backward-compat alias preserved)
 - Agent system migrated to harness-agnostic canonical format
 - Pi settings sync now merges host and Nix-managed values via deep_merge
 ### Fixed
 - Pi settings sync race condition on first run
 ```
 **Step 3: Commit**
 ```bash
 git commit -m "docs: add CHANGELOG.md"
 ```
 ---
 ## Phase 5: Minor Cleanups (Low Risk)
 ### Task 9: Clean up pkgs/default.nix unused `system` binding
 **Objective:** The `system = pkgs.stdenv.hostPlatform.system;` binding in `pkgs/default.nix` is only used for the two input-pass-throughs. If those are the only consumers, it's fine, but add a clarifying comment.
 **Files:**
 - Modify: `pkgs/default.nix`
 **Step 1: Add clarifying comment**
 ```nix
 {
  pkgs,
  inputs,
  ...
 }: let
  # Only used for flake input pass-throughs below
  system = pkgs.stdenv.hostPlatform.system;
 in {
  ...
 ```
 **Step 2: Commit**
 ```bash
 git commit -m "docs: clarify system binding in pkgs/default.nix"
 ```
 ---
 ### Task 10: Remove commented-out overlay entries in overlays/default.nix
 **Objective:** Clean up the large block of commented-out code in `overlays/default.nix` (nodejs_24, paperless-ngx, anytype-heart, hyprpanel, etc.). These belong in git history, not in active code.
 **Files:**
 - Modify: `overlays/default.nix`
 **Step 1: Remove commented-out blocks**
 Remove:
 - The `rose-pine-hyprcursor` addition from `additions` (if it's unused — check with grep)
 - The commented-out `nodejs_24`, `paperless-ngx`, `anytype-heart`, `trezord`, `mesa`, `hyprpanel` blocks from `modifications`
 - The commented-out overlay inputs (`temp-packages`, `stable-packages`, `pinned-packages`, `locked-packages`, `master-packages`) if they reference inputs not in `flake.nix`
 Actually, `nixpkgs-stable`, `nixpkgs-9e9486b`, `nixpkgs-9472de4`, `nixpkgs-locked`, `nixpkgs-master` are NOT in the current `flake.nix` inputs. These overlays will fail if referenced. They should either be removed or the inputs should be added.
 **Action:**
 - Keep `master-packages` IF `nixpkgs-master` is in flake.nix inputs (it IS — good)
 - Remove `temp-packages`, `pinned-packages`, `locked-packages` (inputs don't exist)
 - Keep `stable-packages` IF `nixpkgs-stable` exists in inputs (check — it does NOT currently exist)
 - Keep `additions` with `rose-pine-hyprcursor` IF `rose-pine-hyprcursor` input exists (check)
 **Step 2: Verify**
 ```bash
 nix flake check
 ```
 **Step 3: Commit**
 ```bash
 git commit -m "chore: remove dead overlay entries for non-existent flake inputs"
 ```

 Note: `nix flake init` copies the template contents into the current directory. Use a subdirectory name:
 ```bash
 mkdir new-package && cd new-package
 nix flake init -t ..#package
 ```
 ## Package Template
 Creates a complete package structure:
 ```
 templates/package/
 ├── default.nix    # Package definition with comments
 ```

 # - Dedicated isolated runtime identity (pi-agent user/group)
 # - Host UX via `pi` wrapper command
 # - Per-host-user project allowlists (different roots per user)
 # - No container mode
 # - Merge user Pi config + Nix-managed settings/env into isolated runtime
