work-checklist

work-checklist is a skill for Claude Code, Codex from xcaeser/work-skill. It costs 77 tokens per session (1,593 once invoked), scanned A, original, MIT.

A tool that turns a conversation into a short checklist whose items can be traced back to requirements, decisions, experiments, or concerns.

In plain words
What is it for?
It is for capturing discussions as deliverables or decisions, and, when requested, registering a goal and carrying out the checklist.
Why use it?
It helps preserve what was actually agreed, including open questions and safeguards, without inventing extra work.

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

work-checklist 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 — 136 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Work / 6. Checklist

Turn conversation into accountable next steps. Preserve reliability, meaningful testing, simplicity, user state, and clean breaks. Do not flatten an idea into a defect list or invent work to make the checklist look complete.

Use the strongest current source, in this order:

  1. The user's latest explicit decisions and constraints.
  2. A $work-ideate decision, $work-plan output, or named requirements.
  3. A $work-concern or $work-audit result.
  4. The smallest coherent outcome supported by the current conversation.

Preserve open questions as open questions. Distinguish evidence, assumptions, preferences, commitments, and rejected directions.

Choose the mode

  • Capture: When the user asks to make, save, organize, or turn the conversation into a checklist without asking for execution, return the checklist only. Do not create a goal, inspect unrelated files, or edit anything.
  • Execute: When the user asks to implement, do, resolve, go through, or complete the checklist, register one goal and work every item.

If intent is ambiguous, default to Capture and end with the exact command or sentence that would start execution. Do not silently turn planning into implementation.

Do not spawn agents. The parent owns verification, edits, integration, and proof. If execution genuinely requires orchestration, preserve the approved checklist and hand it unchanged to $work.

Build the checklist

Merge duplicates and order items by dependency first, then user value and risk. Use one of these types:

  • deliverable: something that must exist or change;
  • decision: a choice that must be resolved;
  • experiment: evidence needed before committing to a direction;
  • guardrail: a boundary or non-goal that must remain true;
  • concern: a suspected implementation problem to verify and resolve or disprove.

Keep Capture mode to at most 10 items unless the user explicitly asks for an exhaustive breakdown. Every item must trace directly to the conversation. Do not invent architecture, screens, features, edge cases, research sample sizes, success thresholds, or implementation chores. If a necessary detail is unknown, create one decision item instead of choosing it for the user.

Changes

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.
