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

safe-docx 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 1mo 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.

The opening of the file, as written. The whole thing — 76 lines — stays where its author put it; the contents beside it link to each section on GitHub.

OpenSpec Instructions

These instructions are for AI assistants working in this project.

Always open @/openspec/AGENTS.md when the request:

  • Mentions planning or proposals (words like proposal, spec, change, plan)
  • Introduces new capabilities, breaking changes, architecture shifts, or big performance/security work
  • Sounds ambiguous and you need the authoritative spec before coding

Use @/openspec/AGENTS.md to learn:

  • How to create and apply change proposals
  • Spec format and conventions
  • Project structure and guidelines

Keep this managed block so 'openspec update' can refresh the instructions.

ECMA-376 conformance

safe-docx targets a defined subset of ECMA-376 5th edition. Spec conformance is a foundational property of this repo, not a side concern, so the machinery lives at the repo root rather than under openspec/.

When editing OOXML behavior, lead conformance claims with a @conformance ECMA-376 edition <N>, Part <N> § <SECTION> JSDoc tag and demote internal #NNN issue references to @see. Tests use testAllure.conformance({ spec, edition, part, section }). The lint npm run check:conformance-citations enforces both.

Workflow Conventions

Follow all conventions in CONTRIBUTING.md. The rules below are mandatory for AI agents:

Branch Naming

  • ALWAYS create a branch before committing. Never commit directly to main.
  • Issue work: {issue}-{short-description}-{YYYYMMDD} (e.g., 42-add-redline-support-20260221)
  • Minor fixes: tweak-{description} (e.g., tweak-fix-typo-in-readme)

Commits

  • Use conventional commit format: type(scope): imperative description
  • Valid types: feat, fix, refactor, test, docs, chore, ci, perf, style
  • Scope to the package: feat(docx-primitives):, fix(safe-docx):, refactor(docx-comparison):
  • Body MUST explain WHY, not just what. Longer is better.
  • Reference the issue: Fixes: #N or Ref: #N

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.
