sdlc-feature

sdlc-feature is a command for coding agents from MCKRUZ/claude-code-sdlc. It costs 0 tokens per session (1,466 once invoked), scanned A, original, MIT.

An interview-driven tool that turns an epic into channel-specific features and buildable specifications. An epic is a large piece of planned work; a feature describes how it will reach customers, and a specification gives developers concrete requirements.

In plain words
What is it for?
Use it to identify channels and user groups, ask focused planning questions, and write a feature brief inside an SDLC project or a standalone repository. SDLC means the software development life cycle.
Why use it?
It fills the planning gap between deciding what a large effort should achieve and deciding exactly what should be built for each customer channel or audience.

Command

Installs and runs on its own, but its text points at files inside its plugin — anything it tells you to read at a ${CLAUDE_PLUGIN_ROOT} path is only there once the plugin is installed. Installing the plugin gets both.

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-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.

/sdlc-feature — Decompose an Epic into Channel-Aware Features and Specs

Drive the epic → feature → spec decomposition that the plugin lacks today — the "featuring" hop where you decide how a feature is delivered (which customer channels, which personas) and carve it into buildable specs. Output is feature-brief.md, authored on every channel-bound feature. This is interview-driven like /sdlc-coach: the feature-architect agent assesses what's there, asks focused questions, and drafts the brief as answers arrive — it proposes, a named human decides (the One Rule). Works inside an SDLC project or standalone against any repo.

Instructions

  1. Resolve context:

    • Workflow mode (default): .sdlc/state.yaml exists. Read the epic from .sdlc/artifacts/01-requirements/epics.md, the requirements from requirements.md, and any user-stories.md; the brief lands in .sdlc/artifacts/01-requirements/feature-brief.md.
    • Standalone mode (--repo <path>, or no .sdlc/ found): operate on the given repo with provisional context. Note the missing engagement context in the brief's header and write it to the given --output (default alongside the repo).
  2. Assess what exists: Read the epic and any prior requirements/persona/channel-sensing work. The feature-brief sits below the epic — it decomposes one epic into features + specs; it does not replace epics.md or the stories. If no epic is available, ask the human to name the epic and its outcome before decomposing.

  3. Run the interview: Spawn the feature-architect agent (Product discipline). It runs the coach-style dialogue — which epic; the single coherent slice of value (the feature); who the customer is and how they reach it (the channel is sensed here); whether there is shared "brains" logic multiple surfaces reuse (a channel-agnostic spec); and any product choice not yet decided that the agent must not guess. It drafts feature-brief.md from templates/phases/01-requirements/feature-brief.md — each ## section names its owning discipline, with a Channels × personas narrative and a decomposition table whose rows carry channel + persona columns. Channel-agnostic rows (channel: —) are first-class — the shared brains the surfaces build on. One channel per spec.

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-feature 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 1,466 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.
