dev-workflow

dev-workflow is a skill for Claude Code, Codex from hideki5123/agent-skill-set. It costs 211 tokens per session (5,007 once invoked), scanned B, original, no licence file.

A development workflow that uses TDD, or test-driven development: write a failing test, make it pass, then improve the code. It also plans work, uses multiple agents for review, and can isolate changes in worktrees.

In plain words
What is it for?
Use it to plan and implement features, create requirements, develop with strict TDD, review the work with multiple agents, and manage isolated branches.
Why use it?
It gives feature work a repeatable sequence with tests and review checkpoints. Worktree isolation helps keep separate changes apart while development is in progress.

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 B, and why

dev-workflow scanned grade B with 1 finding 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.

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.
