Session Memory

Overview

Persistent memory system that survives Claude Code's message compaction. Uses three markdown files in .claude/cc10x/ as a permission-free database for continuity, consistency, and pattern compounding.

Memory Surfaces

1. activeContext.md -- Current focus, decisions, learnings, next steps, blockers
2. patterns.md -- Project conventions, architecture decisions, common gotchas, reusable solutions
3. progress.md -- Task completion tracking with verification evidence

Iron Law

EVERY WORKFLOW MUST:

1. LOAD memory at START (and before key decisions)
2. 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

1. Read file
2. Verify anchor exists
3. Edit with exact old_string
4. 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.
