# Checkpoint an FSL task

Use this skill at a meaningful boundary, before `/compact`, before `/clear`, and before handing work to another agent or person.

1. Re-read `tasks/active.md`, `git status --short`, and the relevant diff.
2. Verify changed files and observed command output instead of relying on conversation history.
3. Preserve the goal, authority surface, current state, decisions, invariants, evidence, changed files, failed approaches, verification results, remaining work, and one concrete next action.
4. Remove narration, raw logs, superseded hypotheses, and machine-specific absolute paths.
5. Do not claim a test or check passed unless its output was observed in this worktree.

The result must let a fresh Codex session continue safely without reconstructing the conversation.
