checkpoint

checkpoint is a command for Claude Code from 16wells/claude-project-setup. It costs 25 tokens per session (609 once invoked), scanned A, original, MIT.

A command for making a full project checkpoint: updating the current state, recording activity, routing decisions and insights, then committing and pushing the changes.

In plain words
What is it for?
Use it when you need to refresh project status, record decisions, update activity logs, capture risks and next steps, and send the checkpoint to the project repository.
Why use it?
It keeps project notes and version control aligned after a work session, so another person or agent can understand what changed and where to continue.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

checkpoint scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 3d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 52 lines — stays where its author put it; the contents beside it link to each section on GitHub.

The user just asked for a checkpoint. The trigger-based discipline isn't enough right now — they want a full pass. Run it cleanly.

Step 1 — Refresh 01-context/state.md

Update every section that has changed since the last write. In particular:

  • Active Sub-Project — confirm the active slug; update if focus has shifted.
  • In-Progress Work — what's the next concrete step right now? Which surface? Which file?
  • Awaiting Human Decision — what's actually blocking? Restate the question and the options on the table.
  • Most Recent Commit — pull the latest SHA and subject from git; note what it landed and what it intentionally didn't.
  • External Systems State — for technical projects, refresh the deployed-services / cloud-resources / secrets / scheduled-jobs / production-data tables to reflect reality.
  • Open Risks / Known Mid-Recovery Items — any half-done work that hasn't landed yet.
  • Resume Notes for the Next Agent — one or two bullets, the shortest "do this next" possible.
  • Last updated — ISO timestamp + which surface you're on.

Keep the file under ~200 lines. If something doesn't fit there, it belongs in activity-log.md, the decisions log, or a deliverable file — move it.

Step 2 — Append to 01-context/activity-log.md

One concise entry covering everything since the last activity-log entry. Format per the template at the top of that file. Keep it tight — this file gets read at session start.

Step 3 — Route any new decisions or insights

  • If anything settled or opened a new question that isn't yet in 01-context/decisions-log.md → add it.
  • If you noticed a pattern, gotcha, or quirk that isn't yet in 01-context/insights.md → add it.
  • Don't duplicate. If a decision is logged in decisions-log, just reference it from activity-log; don't restate it.

Step 4 — Stage, commit, push

git add -A
git commit -m "checkpoint: <short topic>"
git push

Use the user-provided topic from $ARGUMENTS if given; otherwise summarize the activity-log entry in 6–10 words.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
