Raw Blame History

Agent Permissions Refinement

TL;DR

Quick Summary: Refine OpenCode agent permissions for Chiron (planning) and Chriton-Forge (build) to implement 2025 AI security best practices with principle of least privilege, human-in-the-loop for critical actions, and explicit guardrails against permission bypass.

Deliverables:

Updated agents/agents.json with refined permissions for Chiron and Chriton-Forge

Critical bug fix: Duplicate external_directory key in Chiron config

Enhanced secret blocking with additional patterns

Bash injection prevention rules

Git protection against secret commits and repo hijacking

Estimated Effort: Medium Parallel Execution: NO - sequential changes to single config file Critical Path: Fix duplicate key → Apply Chiron permissions → Apply Chriton-Forge permissions → Validate

Context

Original Request

User wants to refine agent permissions for:

Chiron: Planning agent with read-only access, restricted to read-only subagents, no file editing, can create beads issues
Chriton-Forge: Build agent with write access restricted to ~/p/**, git commits allowed but git push asks, package install commands ask
General: Sane defaults that are secure but open enough for autonomous work

Interview Summary

Key Discussions:

Chiron: Read-only planning, no file editing, bash denied except for bd * commands, external_directory ~/p/** only, task permission to restrict subagents to explore/librarian/athena + chiron-forge for handoff
Chriton-Forge: Write access restricted to ~/p/**, git commits allow / git push ask, package install commands ask, git config deny
Workspace path: ~/p/** is symlink to ~/projects/personal/** (just replacing path reference)
Bash security: Block all bash redirect patterns (echo >, cat >, tee, etc.)

Research Findings:

OpenCode supports granular permission rules with wildcards, last-match-wins
2025 best practices: Principle of least privilege, tiered permissions (read-only auto, destructive ask, JIT privileges), human-in-the-loop for critical actions
Security hardening: Block command injection vectors, prevent git secret commits, add comprehensive secret blocking patterns

Metis Review

Critical Issues Identified:

Duplicate external_directory key in Chiron config (lines 8-9 and 27) - second key overrides first, breaking intended behavior
Bash edit bypass: Even with edit: deny, bash can write files via redirection (echo "x" > file.txt, cat >, tee)
Git secret protection: Agent could commit secrets (read .env, then git commit .env)
Git config hijacking: Agent could modify .git/config to push to attacker-controlled repo
Command injection: Malicious content could execute via $(), backticks, eval, source
Secret blocking incomplete: Missing patterns for .local/share/*, .cache/*, *.db, *.keychain, *.p12

Guardrails Applied:

Fix duplicate external_directory key (use single object with catch-all "*": "ask" after specific rules)
Add bash file write protection patterns (echo >, cat >, printf >, tee, > operators)
Add git secret protection (git add *.env*: deny, git commit *.env*: deny)
Add git config protection (git config *: deny for Chriton-Forge)
Add bash injection prevention ($(*, `*, eval *, source *)
Expand secret blocking with additional patterns
Add /run/agenix/* to read deny list

Work Objectives

Core Objective

Refine OpenCode agent permissions in agents/agents.json to implement security hardening based on 2025 AI agent best practices while maintaining autonomous workflow capabilities.

Concrete Deliverables

Updated agents/agents.json with:
- Chiron: Read-only permissions, subagent restrictions, bash denial (except bd *), no file editing
- Chriton-Forge: Write access scoped to ~/p/**, git commit allow / push ask, package install ask, git config deny
- Both: Enhanced secret blocking, bash injection prevention, git secret protection

Definition of Done

Permission configuration updated in agents/agents.json
JSON syntax valid (no duplicate keys, valid structure)
Workspace path validated (~/p/** exists and is correct)
Acceptance criteria tests pass (via manual verification)

Must Have

Chiron cannot edit files directly
Chiron cannot write files via bash (redirects blocked)
Chiron restricted to read-only subagents + chiron-forge for handoff
Chriton-Forge can only write to ~/p/**
Chriton-Forge cannot git config
Both agents block secret file reads
Both agents prevent command injection
Git operations cannot commit secrets
No duplicate keys in permission configuration

Must NOT Have (Guardrails)

Edit bypass via bash: No bash redirection patterns that allow file writes when edit: deny
Git secret commits: No ability to git add/commit .env or credential files
Repo hijacking: No git config modification allowed for Chriton-Forge
Command injection: No $(), backticks, eval, source execution via bash
Write scope escape: Chriton-Forge cannot write outside ~/p/** without asking
Secret exfiltration: No access to .env, .ssh, .gnupg, credentials, secrets, .pem, .key, /run/agenix
Unrestricted bash for Chiron: Only bd * commands allowed

Verification Strategy (MANDATORY)

This is configuration work, not code development. Manual verification is required after deployment.

Test Decision

Infrastructure exists: YES (home-manager deployment)
User wants tests: NO (Manual-only verification)
Framework: None

Manual Verification Procedures

Each TODO includes EXECUTABLE verification procedures that users can run to validate changes.

Verification Commands to Run After Deployment:

Single file sequential changes - no parallelization possible.

Single-Threaded Execution:
Task 1: Fix duplicate external_directory key
Task 2: Apply Chiron permission updates
Task 3: Apply Chriton-Forge permission updates
Task 4: Validate configuration

Dependency Matrix

TODOs

Implementation tasks for agent configuration changes. Each task MUST include acceptance criteria with executable verification.

1. Fix Duplicate external_directory Key in Chiron Config

What to do:
- Remove duplicate external_directory key from Chiron permission object
- Consolidate into single object with specific rule + catch-all "*": "ask"
- Replace ~/projects/personal/** with ~/p/** (symlink to same directory)
Must NOT do:
- Leave duplicate keys (second key overrides first, breaks config)
- Skip workspace path validation (verify ~/p/** exists)
Recommended Agent Profile:

Category: quick
- Reason: Simple JSON edit, single file change, no complex logic
Skills: git-master
- git-master: Git workflow for committing changes
Skills Evaluated but Omitted:
- research: Not needed (no investigation required)
- librarian: Not needed (no external docs needed)
Parallelization:
- Can Run In Parallel: NO
- Parallel Group: Sequential
- Blocks: Tasks 2, 3 (depends on clean config)
- Blocked By: None (can start immediately)

Acceptance Criteria:

CRITICAL: AGENT-EXECUTABLE VERIFICATION ONLY

Automated Verification (config validation): ```bash

Agent runs:

jq '.' /home/m3tam3re/p/AI/AGENTS/agents/agents.json > /dev/null 2>&1

Assert: Exit code 0 (valid JSON)

Verify single external_directory key in chiron permission object

cat /home/m3tam3re/p/AI/AGENTS/agents/agents.json | jq '.chiron.permission | keys' | grep external_directory | wc -l

Assert: Output is "1" (exactly one external_directory key)

Verify workspace path exists

ls -la ~/p/ 2>&1 | head -1

Assert: Shows directory listing (not "No such file or directory")

```

Evidence to Capture:
- jq validation output (exit code 0)
- external_directory key count output (should be "1")
- Workspace path ls output (shows directory exists)
Commit: NO (group with Task 2 and 3)
2. Apply Chiron Permission Updates

What to do:
- Set edit to "deny" (planning agent should not write files)
- Set bash permissions to deny all except bd *:
```
"bash": {
  "*": "deny",
  "bd *": "allow"
}
```
- Set external_directory to ~/p/** with catch-all ask:
```
"external_directory": {
  "~/p/**": "allow",
  "*": "ask"
}
```
- Add task permission to restrict subagents:
```
"task": {
  "*": "deny",
  "explore": "allow",
  "librarian": "allow",
  "athena": "allow",
  "chiron-forge": "allow"
}
```
- Add /run/agenix/* to read deny list
- Add expanded secret blocking patterns: .local/share/*, .cache/*, *.db, *.keychain, *.p12
Must NOT do:
- Allow bash file write operators (echo >, cat >, tee, etc.) - will add in Task 3 for both agents
- Allow chiron to invoke build-capable subagents beyond chiron-forge
- Skip webfetch permission (should be "allow" for research capability)

```
"external_directory": {
  "~/p/**": "allow",
  "*": "ask"
}

```
"bash": {
  "$(*": "deny",
  "`*": "deny",
  "eval *": "deny",
  "source *": "deny"
}
```

"bash": {
  "git add *.env*": "deny",
  "git commit *.env*": "deny",
  "git add *credentials*": "deny",
  "git add *secrets*": "deny"
}
```
- Add expanded secret blocking patterns to read permission:

Must NOT do:
- Remove existing bash deny rules for dangerous commands (dd, mkfs, fdisk, parted, eval, sudo, su, systemctl, etc.)
- Allow git config modifications
- Allow bash to write files via any method (must block all redirect patterns)
- Skip command injection prevention ($(), backticks, eval, source)
