claude-code - 💡(How to fix) Fix [Bug] Skills injected in system prompt not persisted across agent messages [1 comments, 2 participants]

Bug Description The skill is active on the CLI side (toggle on, project, ~60 tok), but the harness has never injected its list into any system-reminder on the agent side. There's a disconnect between two layers: the user-facing skills picker works, but agent-facing skills injection does not.

This is probably a Claude Code bug in this session (long-running conversation, lazy injection never fired, or the list was emitted once at the start and fell out of context).

Two diagnostic tests

1. Direct invocation test (fastest): in a new message, simply type /github-commit. The system prompt explicitly allows invoking user-authored skills as /<name>, independent of the auto-discovery list. If the Skill tool accepts and the skill fires — the execution mechanism works, only the listing/announcement broke. If it rejects — a deeper bug.
2. Restart test: /exit → new session in the same repo. If in the first messages of the new session a system-reminder contains an available-skills block with github-commit — that confirms it's stale state in this session (a one-time injection at the start that either slipped through earlier / never happened).
