Specflow CLAUDE.md

Specflow CLAUDE.md is an instructions file for Claude Code from Hulupeep/Specflow. It costs 2,106 tokens per session, scanned A, original, MIT.

Instructions for Specflow, a Node.js and JavaScript framework built around contracts, agents, hooks, and templates.

In plain words
What is it for?
Use them before changing protected files, running contract or hook tests, creating commits, or completing work tied to a GitHub issue.
Why use it?
They enforce project rules that prevent untracked work, invalid contract changes, issue-less commits, and unfinished tests.

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

Specflow CLAUDE.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 6d 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.

Project Context

Repository: Hulupeep/Specflow Project Board: GitHub Issues Board CLI: gh (must be installed and authenticated) Tech Stack: Node.js, JavaScript, Jest Primary Focus: Specflow methodology framework — contracts, agents, hooks, templates


Specflow Rules

Rule 1: No Ticket = No Code

All work requires a GitHub issue before writing any code.

Rule 2: Commits Must Reference an Issue

NEVER run git commit without a #<issue-number> in the message.

If you don't know the issue number, ASK before committing.

# Good
git commit -m "feat: add agent validation (#42)"

# Bad — hooks find nothing, no tests run
git commit -m "feat: add agent validation"

Rule 3: Contracts Are Non-Negotiable

Check docs/contracts/ before modifying protected files.

npm test -- contracts    # Must pass

Violation = build fails = PR blocked.

Rule 4: Tests Must Pass Before Closing

npm test                 # All tests (558+)
npm test -- contracts    # Contract tests only
npm test -- hooks        # Hook tests only
npm test -- schema       # Schema validation only
npm test -- compile      # Compiler tests only

Work is NOT complete if tests fail.

Rule 5: Contracts Are YAML, Not Markdown

NEVER write contract content (invariants, forbidden patterns, required patterns) into .md files.

Contracts MUST be YAML files in docs/contracts/:

  • Feature contracts: docs/contracts/feature_*.yml
  • Journey contracts: docs/contracts/journey_*.yml
  • Default contracts: docs/contracts/*_defaults.yml

Wrong: docs/specflow/my-feature-invariants.md Right: docs/contracts/feature_my_feature.yml

Contract Locations

Project contracts docs/contracts/*.yml
Template contracts templates/contracts/*.yml
Contract tests tests/contracts/*.test.js
Schema tests tests/schema/*.test.js
Hook tests tests/hooks/*.test.js
Compiler tests tests/compile/*.test.js

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.
