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

TreeWork AGENTS.md 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 26d 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

TreeWork Repository Guidance

TreeWork is a standalone, single-file Agent Skill. This repository also contains an optional experimental Codex plugin and the source used to maintain it.

Read Before Editing

  • Standalone workflow behavior: read skills/treework/SKILL.md.
  • Experimental plugin workflow behavior: read the relevant file under plugins/treework/skills/treework/references/.
  • Build Tree runtime: read docs/architecture/build-tree-runtime.md.
  • Transaction, event, checkpoint, or projection behavior: read docs/architecture/transaction-projection.md.
  • Project Map product behavior: read docs/product/project-map.md.
  • Development and release commands: read docs/development.md and docs/releasing.md.

Repository Boundaries

  • plugins/treework/ is the installable experimental Codex plugin. Keep it free of project history, UI source, prototypes, and maintainer-only documents.
  • skills/treework/ is the independently installable TreeWork Skill. Keep its complete working contract in one self-contained SKILL.md.
  • Agent references explain how to use TreeWork. Do not put Rust modules, API internals, migration plans, or frontend architecture there.
  • project-map-ui/ is source; plugins/treework/assets/graph-panel/ is generated output.
  • .TreeWork/ is user-project state created by TreeWork and must never be bundled into the installable plugin.

Change Discipline

  • Preserve the mental model: align intent, build the tree, work along its branches.
  • Keep the standalone Skill free of runtime dependencies and mandatory CLI rules.
  • Add or update tests for public behavior.
  • Run make test and make validate before declaring a change complete.

Experimental Runtime Boundaries

  • Keep the Agent-facing command surface small.
  • Do not add Team, Runner, assignment, or provider-session state.
  • Project Map remains a read-only projection.
  • Machine-owned accepted state changes only through transactions.
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.
