Rename directories to plural form: skill/ → skills/, agent/ → agents/, command/ → commands/

- Rename skill/ to skills/ for consistency with naming conventions
- Rename agent/ to agents/ and command/ to commands/
- Update AGENTS.md with all directory references
- Update scripts/test-skill.sh paths
- Update prompts/athena.txt documentation

This aligns with best practices of using plural directory names and updates
all documentation to reflect the new structure.

+# User Correction Signal Patterns
+
+Patterns that indicate the user is correcting or refining the agent's behavior.
+
+## High Priority Signals (Explicit Corrections)
+
+**Direct corrections:**
+- "No, that's not right..."
+- "Actually, you should..."
+- "Don't do X, instead do Y"
+- "That's incorrect..."
+- "You misunderstood..."
+
+**Explicit instructions:**
+- "Always..." / "Never..."
+- "From now on..."
+- "Make sure to..."
+- "Remember to..."
+
+**Repeated clarifications:**
+- User re-explains the same point multiple times
+- User provides same instruction in different words
+- User corrects same mistake in multiple sessions
+
+**Workflow corrections:**
+- "You skipped step X"
+- "You should have done Y first"
+- "That's the wrong order"
+
+## Medium Priority Signals (Effective Patterns)
+
+**Positive reinforcement:**
+- "That's perfect"
+- "Exactly what I needed"
+- "Great, keep doing it this way"
+- "Yes, that's the right approach"
+
+**User adopts the pattern:**
+- User requests same workflow multiple times
+- User references previous successful interaction
+- User asks to "do it like last time"
+
+**Implicit preferences:**
+- User consistently asks for specific format
+- User regularly requests certain tools/approaches
+- Patterns in how user phrases requests
+
+## Low Priority Signals (Observations)
+
+**General feedback:**
+- "Hmm, interesting..."
+- "I see..."
+- Neutral acknowledgments
+
+**Exploratory questions:**
+- "What if we tried..."
+- "Could you also..."
+- "I wonder if..."
+
+**Context clues:**
+- Time of day patterns
+- Task batching preferences
+- Communication style preferences
+
+**Environment signals:**
+- Tools user prefers
+- File organization patterns
+- Workflow preferences
+
+## Anti-Patterns (Not Corrections)
+
+**Questions about capabilities:**
+- "Can you do X?" (not a correction, just inquiry)
+
+**Exploration:**
+- "Let's try something different" (exploration, not correction)
+
+**Context changes:**
+- "Now let's work on Y" (topic shift, not correction)
