specrew: Skill for Claude Code

.agents/skills/specrew-design-workshop/SKILL.md

specrew-design-workshop is a skill for Claude Code, Codex from alonf/specrew. It costs 193 tokens per session (10,270 once invoked), scanned A, original, MIT.

A workshop guide for making design decisions about a software feature one topic at a time. Its topics include architecture, data storage, user experience, security, integrations, operations, and implementation.

In plain words
What is it for?
Use it during feature planning and design analysis to work through technical structure, requirements, interface design, data, security, APIs, operations, reliability, and code.
Why use it?
It turns design review into a guided conversation so important decisions are discussed at the point they matter.

Skill for Claude CodeCodex

Written for no agent in particular: nothing here depends on one. Also seen: names the AskUserQuestion tool; installed under .agents/ (shared by several agents); mentions Codex.

This is alonf/specrew's own configuration. It tells Claude Code and Codex how to work on specrew itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything specrew configures →

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

specrew-design-workshop 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.

Type: Facilitation Skill Schema: v1 Status: Active design-lifecycle conduct

Purpose

Drive the design lenses as a real, point-of-use workshop — not a checklist skimmed once at launch. Each time you reach a lens, this skill is loaded fresh so the conduct is in focus exactly when you use it. It is self-contained: one load gives you everything you need for the current lens. Because most hosts do not guarantee a fresh reload per turn, re-invoke this skill (or re-read it) at the start of each new lens.

The Big Picture (read this first, every time)

You are facilitating a design conversation with a human, one lens at a time. The lenses live in extensions/specrew-speckit/knowledge/design-lenses/ (deployed under the project's design-lens catalog): architecture-core, component-design, requirements-nfr, ui-ux, data-storage, security-compliance, integration-api, devops-operations, observability-resilience, code-implementation. For each lens you work:

  1. Load that lens's md (design-lenses/<lens-id>.md) for its ## Design Decision Points and ## Workshop Conduct — that is the lens's focused agenda. Do not improvise it from memory.
  2. Facilitate the discussion for that lens (the method below).
  3. Record the decisions + agreement.
  4. Re-invoke this skill and go to the next lens.

The per-lens knowledge is in the lens md; this skill is the method that ties the lenses together. Keep both in view.

Render before you ask — the question may only reference what is on screen (A6/A7/FR-037). Before you raise ANY confirm/approve question (as a typed "does this work? / move on? / approve" prompt) about the lens agenda + depths, a per-lens diagram, the component map, an options/trade-off set, or a design verdict — the thing you are asking about MUST already be rendered in your assistant message in THIS exchange, in prose / console-ASCII the human can see. The question may reference ONLY content that is on screen. Never ask from a count ("8 lenses", "13 components"), a summary ("the agenda", "the map"), or a "shown above / as proposed" that was not actually shown. The failure mode this exists to stop is menu-before-render: render + explain, THEN ask. Be verbose — explain the agenda / diagram / map / options fully in prose first, and make the question and choices self-explanatory (not a terse "does this work? — 8 lenses").

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.
