01-sdlc

01-sdlc is a skill for Claude Code from ai-driven-dev/framework. It costs 52 tokens per session (468 once invoked), scanned A, original, MIT.

An end-to-end workflow that turns a software request into a draft pull request by framing the work, implementing it, and reviewing the result.

In plain words
What is it for?
It helps deliver a requested code change, delegate focused tasks, run reviews, challenge the final result, and prepare a draft pull request.
Why use it?
It separates implementation from independent checking and verifies the change before presenting it for review.

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

    Skill enables autonomous high-impact decisions without human-in-the-loop verification. Critical operations (destructive commands, financial transactions, data deletion) should require explicit user confirmation.
    Fix: Add human-in-the-loop confirmation for destructive, irreversible, or high-impact operations. Never auto-execute commands that modify files, send data, or alter system state.

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

01-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 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.

What it actually says

Skill: sdlc

Behavior

Decide the mode as mode.md says, then read only it and the current zone's reference. Verify that every named provider is installed before calling it. A zone that cannot proceed stops the run and says what it would take to resume.

Spawn specialized agents for isolated work. Parallelize independent work when it is faster. Give each agent one focused task that a smaller model can execute. Repeat the responsible zone when delegated work returns an actionable gap.

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.
