sdlc-brief

sdlc-brief is a command for coding agents from MCKRUZ/claude-code-sdlc. It costs 0 tokens per session (831 once invoked), scanned A, original, MIT.

A command that reads a collection of intake documents and drafts a one-page workshop brief. It also identifies contradictions and unanswered questions for a person to review.

In plain words
What is it for?
Use it inside an SDLC project or against any folder of documents to prepare a brief, contradiction list, and question list.
Why use it?
It turns scattered source documents into a focused starting point for a discovery workshop. This makes disagreements and missing information visible before planning begins.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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

sdlc-brief 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.

/sdlc-brief — Generate the Discovery Workshop Brief

Run cross-document analysis on the intake corpus and draft the one-page workshop brief, with the human curating what makes the page. Works inside an SDLC project or standalone against any folder of documents.

Instructions

  1. Resolve context:

    • If .sdlc/state.yaml exists: workflow mode. Corpus is the locked intake catalog (.sdlc/context/intake/); outputs go to .sdlc/artifacts/00-discovery/.
    • If not (or --docs <path> given): standalone mode. Corpus is the given folder; outputs go alongside it. Note in output headers that DOC-NNN IDs are provisional.
  2. Ensure intake exists (workflow mode): If the catalog or per-document summaries are missing, stop and tell the human to run document intake first (Phase 0, Step 0c) — the brief is built on the summaries, not raw files. In standalone mode, read the documents directly.

  3. Run the analysis: Spawn the discovery-analyst agent to produce contradiction-list.md and question-list.md (templates in templates/phases/00-discovery/). Skip if both exist and --refresh was not given.

  4. Curate with the human:

HITL GATE: Present the analysis to the human using the AskUserQuestion tool — this is the step that makes the brief curated rather than generated. Ask: (1) Which contradictions make the one page? (show all blocks-outcome and shapes-design entries with their resolving questions; recommend the top 3-5) (2) Which questions make the one page? (show the workshop-routed list; recommend 8-12 across the agenda blocks; confirm the pre-workshop-routed ones get emailed instead) (3) What are the 3-5 decisions the room must leave with? (4) Logistics: date/time/location, attendees with roles, duration, facilitator.

  1. Draft the brief: Fill templates/phases/00-discovery/workshop-brief.md with the curated content. Hard rules from the template: one page above the appendices; questions only — no proposed outcomes, metrics, or solutions; every claim carries a DOC-NNN reference.

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.

sdlc-brief is a command published in the GitHub repository MCKRUZ/claude-code-sdlc (4 stars, last pushed 6d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 831 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 2026-08-31.
