use-statem

use-statem is a skill for Claude Code, Codex from henryqin1997/statem. It costs 40 tokens per session (1,040 once invoked), scanned A, original, Apache-2.0.

A system for managing long coding tasks with saved states and runbooks. A runbook is a written sequence of steps, and a state machine records which step is active and what happens next.

In plain words
What is it for?
Creating, validating, starting, resuming, saving, and reviewing structured workflows for long Claude Code tasks.
Why use it?
It preserves progress across pauses, retries, reviews, and resumed sessions instead of relying on conversation history alone.

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

use-statem 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.

Use Statem

Use statem as a state-aware runbook for long agent runs. It should guide the work and preserve progress without turning the session into a rigid workflow harness.

Operating Loop

  1. Inspect or create a spec such as statem.yaml.
  2. Run statem validate statem.yaml --json.
  3. Start or resume with statem start statem.yaml --run-id <id> --json.
  4. Before work, run statem cur --run-id <id> --json.
  5. When a state is complete, run statem goto <next> --run-id <id> --json.
  6. Before pausing, run statem save --run-id <id> --json.
  7. For handoff context, read recent history: statem history --run-id <id> --tail 10 --json.

If statem is not on PATH, use python3 -m statem from the repository that contains the Python package.

For dynamic servers, company machines, or disposable git checkouts, prefer a machine-local state directory. Set STATEM_STATE_DIR once, for example $HOME/.local/state/statem/<project>, so runtime state survives checkout replacement. After moving to a new checkout, run statem start <spec> --run-id <id> once to rebind the run to the current spec path.

Commit YAML runbooks with the repo. Do not commit runtime state; treat .statem/ or STATEM_STATE_DIR as local, copy-on-use execution data.

Context Clear

Avoid /clear in normal loops. It flushes the conversation, including any instructions that were supposed to run after it, and can lose useful intent that was not written to durable files. Prefer explicit transitions plus safe compaction. Before a hard clear, run statem prompt --run-id <id> and paste the generated prompt immediately after /clear. After a hard clear, recover from .statem with start, cur, and history instead of relying on previous chat context.

Loop Compaction

For cyclic runbooks, prefer an explicit session hygiene node after a full loop. When another cycle will continue and the context is noisy, run statem compact-prompt --run-id <id>, use the generated /compact instruction, then recover with statem cur and statem history --tail 10.

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.

use-statem is a skill published in the GitHub repository henryqin1997/statem (969 stars, last pushed 3d ago), licensed Apache-2.0. It adds 40 tokens to every session and 1,040 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
