bootstrap-feature

A documentation step for planning a software feature before coding begins. It creates a product requirements document, use cases, architecture review, quality-assurance tests, and an implementation plan.

In plain words
What is it for?
Use it to document a feature, review its design, define test cases, plan implementation, and prepare the development work without producing code.
Why use it?
It turns an unfinished feature idea into a shared plan and exposes design or testing gaps early. It can also prepare a feature branch and working notes.

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

bootstrap-feature 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 3d 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 — 196 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Command: Bootstrap Feature

Arguments

The feature to document is $feature (also available as $ARGUMENTS). When it is empty, ask the user what to document before Step 1 — do NOT infer a feature from surrounding context.

Literal-token flag rule: a documented flag is active ONLY if its literal token appears in $ARGUMENTS. Never infer that a flag was passed because the documentation describes it.

Preflight: Memory Layer Check

Run this FIRST, before Step 1. It takes one Read.

  1. Check that ~/.claude/claude.md exists and contains the marker heading ## Autonomous Development Workflow (MANDATORY).

  2. If the file is missing, or the marker is absent, print this warning verbatim and continue anyway:

    WARNING: the SDLC memory layer is not installed. ~/.claude/claude.md is missing or does not contain the pipeline instruction, so the autonomous workflow is not active for unprefixed requests in this session. Installing the plugin alone is not sufficient — run bash install.sh from the claude-code-sdlc repo to install the memory layer.

  3. Never block on this check. A missing memory layer degrades autonomy; it does not invalidate this run. Warn once and proceed to Step 1.

Known limitation: this preflight only fires when this skill is invoked explicitly. An unprefixed natural-language feature request bypasses it entirely, because nothing runs. That gap closes when the SessionStart hook lands (roadmap F2a).

Agency Documentation Pipeline

Every feature follows this pipeline before any code is written. Each step is performed by a specialized agent role.

Design declaration precheck: when the feature is user-facing AND .claude/rules/design.md does not exist, run design-foundation (or instruct the developer to) before the documentation phases proceed, stating explicitly in the invocation that it is an unattended run — its non-blocking path keys off that marker. If the developer declines, proceed anyway — never block this pipeline on it.

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.

bootstrap-feature is a skill published in the GitHub repository Koroqe/claude-code-sdlc (51 stars, last pushed 5d ago), licensed MIT. It adds 40 tokens to every session and 3,303 once invoked, about $0.0002 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 2026-08-30.
