sdlc-task

sdlc-task is a skill for Claude Code, Codex from redhat-vmeperf/agent-tasks-template. It costs 43 tokens per session (523 once invoked), scanned A, original, Unlicense.

An autonomous seven-stage software development life cycle (SDLC) workflow covering architecture, security planning, team coordination, coding, review, quality checks, and security auditing.

In plain words
What is it for?
Use it to run a software task from design through implementation and testing, handle in-scope findings, flag out-of-scope findings, and receive a record of the completed process.
Why use it?
It allows the stages to proceed without human approval at each gate while still producing their reports and revisiting earlier decisions when new findings require it.

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-task 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 1mo 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.

What it actually says

sdlc-task Skill

Platform-agnostic definition for the autonomous (ungated) SDLC pipeline.

This skill runs the same 7 roles as the standard SDLC pipeline (Architect, Security Architect, Team Lead, Engineer, Code Reviewer, Quality Engineer, Security Auditor) but without human approval gates. All gates are advisory — agents produce their artifacts, surface findings, and self-advance.

When a later gate discovers something that changes architecture, scope, or security posture, the pipeline loops back to Gate 1 to re-evaluate with the new information, then continues forward. This makes the pipeline self-improving, not just advisory.

Behavior

  • All 7 roles execute in sequence and produce their standard artifacts
  • No gate blocks on human approval — agents self-advance
  • Self-correction: discoveries that change architecture, scope, or security posture trigger a loop back to Gate 1 (max 2 re-evaluation cycles to prevent infinite loops)
  • Finding mitigation is driven by the invoker's directions — findings within scope are mitigated, findings outside scope are flagged
  • Audit trail is mandatory (REQ-2), entries marked as UNGATED
  • All common files (CYNEFIN.md, PERSONALITY.md, LESSONS.md, REQUIREMENTS.md) are loaded

Pipeline

See .agents/skills/sdlc-task/PIPELINE.md for the full pipeline process definition.

Invocation Context

This skill may be invoked:

  1. Directly by a human for lower-ceremony tasks
  2. By any pipeline that needs autonomous SDLC-quality analysis without blocking

Changes

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.
