Common Session Retrospective Agent Skill

Analyze conversation corrections to detect skill gaps and prepare targeted skill-library maintenance tasks. Use after any session with user corrections, rework, or retrospective requests. After finding correction loops, also load +common/common-learning-log to persist mistake entries to AGENTS_LEARNING.md.

Session Retrospective

Structure

└── references/
    └── methodology.md    # Signal tables, taxonomy, report template

Protocol

  • Extract — Scan for correction signals (loops, rejections, shape mismatches, lint rework)
  • Classify — Root cause: Skill Missing | Incomplete | Example Contradicts Rule | Workflow Gap | Trigger Miss
  • Trigger Miss Check — For every task in session, ask: _" relevant skill available but not loaded?"_
  • If yes: record skill ID, indirect phrase used, and fix (add keyword alias to triggers)
  • Propose — One fix per root cause: revise existing guidance, update reference, add new skill, or add new workflow
  • Implement — Only when current task explicitly authorizes repository maintenance, apply the approved repo changes across configured agent dirs. Keep SKILL.md concise; move large tables to references/. Update AGENTS.md
  • Log to AGENTS_LEARNING.md — For each correction loop found, append one entry using common/common-learning-log protocol (Signal: Session retrospective)
  • Report — Output correction count, skills changed, trigger misses found, estimated rounds saved

Trigger Miss Output

Emit trigger miss block (schema in references/methodology.md) for each miss detected.

Guidelines

  • Cite specifics: Reference concrete conversation moment per proposal
  • Extend first: Search AGENTS.md before creating — extend existing guidance first
  • One fix per loop: One correction → one targeted skill change
  • Stay task-scoped: Only change repository library source during explicit maintenance work for the repository
  • Sync all agents: Apply to every agent skill dir listed in .skillsrc agents field
  • Follow skill-creator: New skills comply with common/skill-creator standards

Anti-Patterns

  • No Vague Proposals: Cite exact gap + fix, not "make X better"
  • No Duplicate Skills: Search AGENTS.md index first
  • No Oversized Patches: Extract to references/ per skill-creator standard

References

Signal tables, root cause taxonomy, report template, real-world example:

How to use it

Copy the folder

Take hoangnguyen0403/common-session-retrospective from the repository into ~/.claude/skills for personal use, or into .claude/skills inside a project.

Check the name does not clash

The agent identifies a skill by the name field in its header. Two skills with the same name cannot sit side by side — one of them will be ignored.
