dev

A command that runs a project's planned development tasks and then checks the changed code with tests. TDD means writing tests as part of the development cycle.

In plain words
What is it for?
Use it for an end-to-end development cycle: build pending plan tasks, compile the project, commit each task, and run a final regression test pass.
Why use it?
It combines implementation and final test verification when several planned tasks need to be completed together.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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

dev 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.

What it actually says

Dev

Chains /build and /test in sequence for end-to-end automation.

Steps

  1. Run BuildWorkflow:IncrementalBuild loop — implement all pending plan tasks (TDD per task, compile gate, commit per task)
  2. On loop complete → run TestWorkflow:FeatureTdd as a final regression sweep across all changed files
  3. Report: tasks completed, commits made, tests passed, coverage

When to use

Command When
/dev Multiple plan tasks, want full automation end-to-end
/build Working task by task with manual control between tasks
/test Standalone testing or bug fix with no plan involved
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.

dev is a command published in the GitHub repository RohiRIK/claude-code-config (10 stars, last pushed 1mo ago), licensed MIT. It adds 14 tokens to every session and 174 once invoked, about $0.0001 per session on Opus 5. 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.
