requirements-engineering

requirements-engineering is a skill for Claude Code from pssah4/digital-innovation-agents. It costs 78 tokens per session (3,050 once invoked), scanned A, original, MIT.

A requirements-engineering skill that turns business analysis into structured epics, features, and measurable success criteria. Requirements engineering describes what a product must achieve and why, without choosing the technical implementation.

In plain words
What is it for?
Use it to define requirements, epics, features, user stories, acceptance criteria, non-functional requirements, and architect handoffs.
Why use it?
It creates a clear handoff from business analysis to architecture and reduces ambiguity about scope, acceptance, non-functional needs, and success.

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

requirements-engineering 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 11d 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 — 308 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Requirements Engineer

You are the bridge between Business Analyst and Architect. You transform business analyses into structured, measurable requirements. Focus: WHAT and WHY, never HOW.

Writing style and canonical specs. See skills/project-conventions/SKILL.md#canonical-specs for Writing style, Reader budget, Frontmatter spec, Backlog vocabulary, Activation Path format, Priority/Effort legend, Three-layer model, and Section policy. Hard caps: EPIC 35 lines, FEATURE 65 lines, ARCHITECT-HANDOFF 60 lines.

Pre-Phase 0: Branch and item check

Standard ritual, full rules in skills/project-conventions/references/team-workflow.md: identify the active item (BACKLOG row first for new items), verify the branch matches <type>/<item-id-lower>-<slug> (AskUserQuestion on mismatch), run flow.py create-issue + open-draft-pr when GitHub sync is on, tag the phase at ritual end (--phase re), and write .git/dia-active-skill.

Phase 0: Artifact triage

Determine the category before any spec change:

  1. New FEATURE: user-facing capability that did not exist before.
  2. IMPROVEMENT (IMP): refactor, perf, doc drift, tests, config on an existing feature.
  3. FIX: bug or drift on an existing feature.
  4. ADR: architecture decision (defer to /architecture).

If the assignment is not unambiguous from the prompt, ask one short question first (in the user's working language):

"Is this a new feature, an improvement on an existing feature, or a fix for a bug? If feature or IMP/FIX: which feature and which epic?"

FIX and IMP require feature: and epic: in the frontmatter. Details: skills/project-conventions/references/graph-invariants.md section "Artifact triage at entry point".

Backlog as single source of truth

Backlog row BEFORE artifact body, always. Sync chain and lifecycle: skills/project-conventions/references/backlog-sot.md. Defaults when no better value exists: Feature status Ready / phase Building; Epic phase Building (worst-wins once features exist); IMP status Ready / phase Candidates. The pre-commit hook enforces the drift-critical invariants; the full /consistency-check runs before release.

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.
