update

update is a skill for Claude Code, Codex from conorbronsdon/agent-workspace. It costs 26 tokens per session (399 once invoked), scanned A, original, MIT.

A manual checkpoint for an agent session that records progress in a daily log and updates task state when priorities or work status change.

In plain words
What is it for?
Use it to save a short progress note, record a changed priority, mark a task complete, or note that a work thread opened or closed.
Why use it?
It keeps important decisions and progress from being lost during a long session without formally ending the session.

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

update 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 4d 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

/update — Quick Checkpoint

Save progress mid-session without closing. Fast and low-ceremony: a log line plus a state touch only if something actually changed.

Invocation: user-only (disable-model-invocation: true) — checkpoints are timed by you, and the flag keeps this skill out of ambient context.

Configuration

Read the optional workspace.yaml at the project root. Below, <state_dir> and <sessions_dir> are its resolved values; defaults are state/ and sessions/. Full reference: docs/state-model.md.

Instructions

  1. Scan recent conversation. Identify in ~30 seconds: what was worked on, any decisions made, any state changes needed.

  2. Append to session log. Add to <sessions_dir>/{TODAY}.md (create it if absent):

    ## Update: {TIME}
    - {what was worked on, 1–3 bullets max}
    
  3. Update state only if something changed. Touch <state_dir>/current.md only if a priority shifted, a thread opened or closed, or a task completed. Skip otherwise — an /update with no real change writes only the log line.

  4. Confirm. One line: "Checkpointed: {brief description}".

Design principles

  • Fast. A checkpoint should cost seconds, not minutes.
  • Skip what's clean. Don't rewrite current.md for a checkpoint that changed nothing.
  • Standing rule. Whenever you run /update, log first, then decide whether state actually moved — don't invent a state change to justify the run.
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.
