Iron Law

EVERY WORKFLOW MUST:

LOAD memory at START (and before key decisions)
UPDATE memory at END (and after learnings/decisions)

Stable Edit Anchors

Safe section headers for Edit operations:

activeContext: ## Recent Changes, ## Learnings, ## References
patterns: ## Common Gotchas, ## Project SKILL_HINTS
progress: ## Completed, ## Verification

Read-Edit-Verify Pattern

Read file
Verify anchor exists
Edit with exact old_string
Read back to confirm

Tool Rules

Use Write() for NEW files (permission-free)
Use Edit() for EXISTING files (permission-free)
Never use Write() to overwrite existing files
Never compound commands (mkdir && cat)

When to Use

At the start of every CC10X workflow (load)
At the end of every CC10X workflow (update)
Before making key decisions (check patterns)
After discovering learnings or gotchas (persist)

Agents Used

All CC10X agents use this skill. The cc10x-router manages load/update lifecycle.
