req-analyze

req-analyze is a skill for Claude Code, Codex from sd0xdev/sd0x-harness. It costs 101 tokens per session (3,966 once invoked), scanned A, original, MIT.

A requirements-analysis tool that breaks a problem into needs, stakeholders, and priorities before a technical solution is chosen.

In plain words
What is it for?
Use it to decompose requirements and record stakeholder concerns and open questions before writing a technical specification.
Why use it?
It separates what people need from how the software will be built, making the scope easier to understand.

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

req-analyze 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 today.

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.

Requirements Analysis Skill

Trigger

  • Keywords: requirements analysis, analyze requirements, decompose requirements, stakeholder analysis, 需求分析, requirement decomposition, analyze needs

When NOT to Use

  • Solution comparison / feasibility evaluation (use /feasibility-study)
  • Technical specification writing (use /tech-spec)
  • Per-task tracking tickets (use /create-request — requests are date-prefixed non-lifecycle docs for progress tracking, not feature-level requirements docs; see Relationship section below)
  • Issue root cause analysis (use /issue-analyze)
  • Architecture design (use /architecture)
  • Implementation (use /feature-dev)

Boundary Contract

/req-analyze is problem-space only:

  • Defines problems, analyzes stakeholders, decomposes requirements, prioritizes needs
  • Must NOT rank solutions, estimate implementation effort, or produce feasibility recommendations
  • Solution-space concerns discovered during analysis → log as Open Questions with suggestion to run /feasibility-study

Relationship with /create-request

1-requirements.md is a lifecycle document, not a task ticket. They live in different document classes per @rules/docs-numbering.md and serve different audiences.

Dimension /req-analyze1-requirements.md /create-requestrequests/YYYY-MM-DD-*.md
Doc class Lifecycle (Phase 1, numeric prefix) Request ticket (date-prefixed, non-lifecycle — per @rules/docs-numbering.md)
Count per feature One (upsert / incremental refine) Many (one per task)
Position in workflow Before /tech-spec (design phase) After /tech-spec (execution phase)
Content focus Problem space — 5-Why, FR/NFR, MoSCoW, stakeholders Execution — Status, Progress, AC checklist, Related Files
Granularity Feature-wide Single task (AC ≤ 8)
Update pattern Document upsert Status tracking (scan / update / update-all / --verify-ac)
Audience Designers, decision-makers Executors, progress trackers

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.
