Close-Lessons-Learn 150 Protocol

Goal

Capture durable learning from a solved problem and keep the Memory pipeline consistent.

When to use

Use this skill when:

• The user confirms a fix worked (e.g., "works", "fixed", "отлично").
• A non‑obvious bug or root cause was discovered.
• A recurring pattern should be turned into a protocol.
• New architectural insights emerge that should be documented in Project Architecture Quick Reference.

Workflow

1. Read the active session log in

   .sessions/SESSION_[date]-[name].md

   for evidence and context.
2. Open

   MEMORY.md

   (repo root).
3. Append a new Lesson to

   ## 🆕 Lessons (Inbox)

   using this template:

### <YYYY-MM-DD> <Short title>
**Problem:** <what was broken>
**Attempts:** <what was tried, if any>
**Solution:** <what fixed it>
**Why it worked:** <causal explanation>
**Principle:** <one-sentence rule for the future>

4. If 3+ related lessons exist, create a Short‑Term entry:

   • Move the related lessons (or summarize them) into

     ## 🔄 Short-Term Memory

     .
   • Write a common pattern and an emerging principle.

5. If a principle is stable, promote it to

   ## 💎 Long-Term Memory

   as a protocol:
   • Format: Context → Protocol → Reasoning.

6. Review Project Architecture Quick Reference and enhance if needed:

   • Check if the lesson reveals new architectural insights (new directories, patterns, workflows)
   • Add missing directories, workspaces, or key patterns discovered during work
   • Update existing entries with new information or clarifications
   • Keep the reference current and comprehensive

Output expectations

• Report exactly what you recorded or moved.
• If you did not write a lesson, say why.
• If you updated the Project Architecture Quick Reference, specify what was added or modified.

Session Log Entry (MANDATORY)

After completing this skill, write to

.sessions/SESSION_[date]-[name].md

:
