analyze

analyze is a skill for Claude Code, Codex from lantisprime/claude-sdlc. It costs 111 tokens per session (999 once invoked), scanned A, original, MIT.

A requirements-writing phase that turns a planned task into structured, testable requirements with stable IDs such as REQ-001. It also checks whether the task affects a user interface and requires UX designs and brand guidelines when needed.

In plain words
What is it for?
Use it after the planning phase to create or update requirements, identify frontend involvement, and connect requirements to UX artifacts and later test cases.
Why use it?
It prevents requirements from drifting beyond the approved scope and makes each requirement traceable to later tests. The frontend check catches missing design guidance before implementation begins.

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

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 4d 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.

Analyze (Phase 2)

Turn a task into structured, testable requirements.

Prerequisite

The plan gate must exist: .claude/sdlc/gates/plan-<task-slug>.md. If it does not, tell the human to run /plan first.

Step 1 — Detect frontend involvement

Before writing requirements, determine whether the task touches a user interface. Check:

  • The plan's in-scope files for UI frameworks (React, Vue, Angular, HTML templates, mobile views)
  • Keywords in the plan: "screen", "page", "form", "button", "UI", "UX", "design"

If yes, and no UX artifact exists under .claude/sdlc/architecture/ux/:

  • Halt. Ask the human for UX designs (Figma link, wireframes, mockups) and brand guidelines (colors, typography, spacing tokens, component library).
  • Do not proceed to write requirements until a UX artifact is linked or written at .claude/sdlc/architecture/ux/<task-slug>.md.

This is a hard rule. Frontend without UX specs produces UI debt.

Step 2 — Write requirements

Write to .claude/sdlc/requirements/<task-slug>.md using templates/requirements.md. Each requirement has:

  • Stable ID: REQ-<n> — never renumbered once published
  • Title: short imperative
  • Description: what the system must do
  • Acceptance criteria: testable, unambiguous (Given/When/Then works)
  • Priority: must / should / could
  • Source: ticket, CR, stakeholder, or project scope section
  • Dependencies: other REQ IDs or external systems

Stable IDs matter: Design references them, Build validates against them, Test maps cases to them, Deploy records them, Docs traces them.

Step 3 — Contract / scope coverage check

For each requirement, confirm it maps to a section of .claude/sdlc/scope.md (or the relevant contract/SOW artifact). Any unmapped requirement is a scope question — surface it, don't hide it. The human decides whether to expand scope or drop the requirement.

Produce a coverage table in the requirements file:

REQ ID Scope section Status
REQ-001 2.1 Checkout ✓ mapped
REQ-002 ? unmapped

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.

analyze is a skill published in the GitHub repository lantisprime/claude-sdlc (3 stars, last pushed 4mo ago), licensed MIT. It adds 111 tokens to every session and 999 once invoked, about $0.0006 per session on Opus 5. 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 2026-08-31.
