resume

resume is a command for coding agents from jovesun-lab/whetstone. It costs 24 tokens per session (575 once invoked), scanned A, original, MIT.

A command for continuing work from a handoff document, which records what a previous session or agent completed and what remains. It rechecks the document against the actual project before proceeding.

In plain words
What is it for?
Use it when resuming a task after another session or agent. It helps review the stated goal, files, checks, and unresolved gaps.
Why use it?
Handoff notes can be outdated or incomplete. This command helps detect that drift before work continues.

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

resume 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 5d 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.

What it actually says

Resume work from a handoff document written by a previous session or a different agent. The point of this flow is to pick up the thread without inheriting stale state — a handoff is a point-in-time snapshot, and trusting it blindly is exactly how drift creeps in.

  1. Load and orient. Read the handoff (from the given path, or from what the user pasted). Restate the ⭐️ Goal back to the user in one line so they can see you've oriented correctly. A gap in the handoff is a finding — say it. Missing doc, stale date, a goal with no verdict, a thin re-derive section: each is evidence about how the last session ended. Surface it out loud instead of silently patching around it — the protocol self-heals only when the pickup side reports what the wrap side skipped.

  2. Re-derive before trusting. Work through the handoff's "Re-derive on pickup" section. For each named item, reconcile the snapshot against ground truth using whatever access you have:

    • re-read the named artifacts (files, docs, plans);
    • re-run any named check or build;
    • re-confirm that cited facts/numbers are still current. If you lack live access, re-derive from the artifacts you were handed and explicitly flag what you could not verify — don't paper over the gap.
  3. Set up Task Track. Create a task list with the carried-forward ⭐️ MAIN as the goal anchor (exactly one, under its frozen title), and tag the open threads from the handoff by origin (🌶️ / 🍏 / 🍋). See references/task-track.md.

  4. Propose, then execute on a one-word confirm. End your orientation by proposing the handoff's top Open / Next item as a concrete action — "Highest priority is X — want me to start?" — with the rest of the queue visible so the user can redirect. Don't end on an open "what would you like to work on?": that forces the user to ask what's highest and then confirm it — two turns where one would do. The proposal is a default, not a lock; any redirect from the user wins.

If anything in the handoff contradicts ground truth when you re-derive, trust ground truth and say so — the handoff was written before the world moved.

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.
