lessons-capture

What problem does it solve? Development skills in this plugin need a consistent, low-friction way to record improvement observations after each run without risking edits to the skills themselves. This helper centralizes that reflection protocol so every calling skill logs lessons the same way. ## Core Features & Use Cases - Structured reflection: Captures at most one recommendation per run, formatted as observation, proposed change, and expected benefit. - Atomic log appends: Writes dated UTC entries to ~/.claude/dev-skills/lessons/<skill-name>.md using shell append so prior entries are never overwritten. - Safe by design: Never edits any SKILL.md and never writes outside the lessons directory; logs are reviewed and applied later by the user or an improver skill. - Use Case: After feature-design finishes a run, it invokes this helper with its slug, and a dated entry noting a missing guidance step is appended to the feature-design lessons log for later review. ## Quick Start Invoke this skill as the final step of another plugin skill, passing the calling skill's slug such as feature-design as the only argument.
