work-specify

work-specify is a command for Claude Code from christopherlouet/claude-base. It costs 0 tokens per session (476 once invoked), scanned A, original, MIT.

A command that turns a feature request into a structured functional specification before implementation planning. It records user stories, acceptance criteria, requirements, edge cases, success measures, and scope limits.

In plain words
What is it for?
Use it to document a feature’s expected behaviour in a testable form, including priorities, data entities, clarification questions, and out-of-scope work.
Why use it?
It prevents a team from planning or coding before agreeing on what the feature must do. It also exposes unclear requirements and unusual cases early.

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

work-specify 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.

What it actually says

WORK-SPECIFY Agent

Creates a structured functional specification. SPECIFICATION mode only.

Request context

$ARGUMENTS

Objective

Create a complete and testable functional specification BEFORE planning. Step between exploration and planning: EXPLORE -> (BRAINSTORM) -> SPECIFY -> PLAN -> TDD -> AUDIT -> COMMIT Focus on the WHAT (functionality, value), not the HOW (technical implementation).

Workflow

  • Analyze the request: identify WHAT, WHY, actors, actions, data, constraints
  • Write prioritized User Stories (P1=MVP, P2=Important, P3=Nice-to-have)
  • Each US: "As a / I want / So that" format + Given/When/Then criteria
  • Each US must be INVEST (Independent, Negotiable, Valuable, Estimable, Small, Testable)
  • List measurable functional requirements (EF-XXX)
  • Identify edge cases (errors, empty/invalid data)
  • Define key entities if data is involved
  • Define measurable success criteria (CS-XXX)
  • Explicitly delimit out of scope
  • List max 3 clarification points if grey areas exist

Expected output

Generate specs/[feature-name]/spec.md with:

  1. Summary (1-3 sentences, user value)
  2. User Stories (P1 > P2 > P3, with acceptance criteria)
  3. Functional Requirements (EF-XXX)
  4. Edge Cases
  5. Entities (if data is involved)
  6. Success Criteria (measurable metrics)
  7. Out of Scope
  8. Clarification Points (max 3)
Before Usage
/work:work-explore Exploration
After Usage
/work:work-clarify If ambiguities
/work:work-plan Planning

IMPORTANT: NEVER include technical implementation details.

YOU MUST prioritize User Stories (P1 = MVP, P2 = Important, P3 = Nice-to-have).

YOU MUST make every requirement testable and measurable.

NEVER use technical jargon (API, database, framework...) in the spec.

Think hard about USER VALUE before writing.

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.

work-specify is a command published in the GitHub repository christopherlouet/claude-base (5 stars, last pushed 4d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 476 tokens. 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 2026-09-03.
