safe-docx AGENTS.md

Repository instructions for safe-docx, a library for working with DOCX files, the Microsoft Word document format. They describe when to read the project's proposal instructions, how to follow its OpenSpec workflow, and how to maintain conformance with the ECMA-376 document standard.

In plain words
What is it for?
Use them when planning changes, adding capabilities, modifying DOCX or OOXML behavior, checking standard conformance, or preparing branches and commits.
Why use it?
They help keep document-processing changes aligned with the project's specifications, supported file-format scope, branch conventions, and contribution workflow.

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 2d 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.

How it starts

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.
