sdlc

A command that explains what to do in the project’s current software-development phase, including the needed skills and documents to produce. It reads the project’s saved phase and team context.

In plain words
What is it for?
Use it to see the current phase, participating team roles, required work, and expected project artifacts.
Why use it?
It gives developers phase-specific guidance instead of making them search through workflow definitions and project files themselves.

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 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 2d 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 — 69 lines — stays where its author put it; the contents beside it link to each section on GitHub.

/sdlc — Phase Guidance

Show guidance for the current SDLC phase including what to do, which skills to use, and what artifacts to produce.

Instructions

  1. Locate state file: Look for .sdlc/state.yaml in the current project directory. If not found, tell the user to run /sdlc-setup first and exit.

  2. Read state: Load .sdlc/state.yaml to get current_phase.

  3. Load phase definition: Read the phase definition file from phases/XX-phasename.md (where XX is the zero-padded phase number).

  4. Load profile: Read .sdlc/profile.yaml to get stack and quality configuration.

  5. Display phase context: Present to the user:

    Header

    Phase {N}: {Name}
    Profile: {profile_id}
    

    Team & RACI (this phase)

    Read references/team-model.md from the plugin directory and find the entry keyed by the current phase id. Render a short block: which disciplines are active this phase and their per-phase RACI (Responsible / Accountable / Consulted / Informed). This tells each seat — Product, Data, Design, Engineering, Bizreq — where it owns work vs. where it advises.

    • Degrade gracefully: if references/team-model.md is absent, or has no entry for this phase, skip this subsection silently and continue — do not error or emit a placeholder.

    Purpose

    One-line description of this phase's goal.

    Resolved Questions from Previous Phase

    Check the previous phase's handoff document (e.g., phase1-handoff.md when in Phase 1) for a "Resolved Questions" section. If it exists, list the resolved questions as context — these are confirmed inputs that MUST inform the current phase's artifacts. If no resolved questions section exists, note that and move on.

    What to Do Next

    Based on the phase workflow steps, current artifact state, and resolved questions:

    • List the next actionable step
    • Reference the specific skill/command to use
    • Note which resolved questions feed into which artifacts
    • Example: "Write requirements.md using resolved questions RQ-1 through RQ-3 as inputs"

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 is a command published in the GitHub repository MCKRUZ/claude-code-sdlc (4 stars, last pushed 4d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 724 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.
