feature-00c

feature-00c is a command for coding agents from JotJunior/cstk. It costs 80 tokens per session (19,169 once invoked), scanned D, original, MIT.

A command that starts an automated workflow for one software feature after its brief and project rules have been approved. The workflow breaks the feature into a specification, plan, tasks, implementation, and reviews.

In plain words
What is it for?
Use it to run the full specification-driven development process for one feature, from defining requirements through implementation and review.
Why use it?
It coordinates the many steps and records progress, decisions, and pauses in a project state folder, so a complex feature does not depend on manual tracking.

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 D, and why

feature-00c scanned grade D with 3 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 today.

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.

Fronteira command↔orquestrador (lock + init): este command PAI detem o lock (acquire no passo 7, release SEMPRE no Cleanup) e inicializa o state.json (passo 3). O orquestrador NAO adquire lock nem re-inicializa estado — contrato canonico em "Fronteira command↔orquestrador" de agente-00c-feature-orchestrator.md. Identico no resume (/feature-00c-resume).

0. Warm-up de permissoes (CRITICO — antes de qualquer outra coisa)

A pipeline feature-00c invoca varias skills/tools ao longo de ondas. Permissoes pedidas "lazy" quebram a autonomia se o operador nao estiver presente. Solucao: invocar TODAS as skills/tools em batch ANTES de qualquer logica.

Apresente ao operador:

Feature-00C — Warm-up de permissoes

Vou agora invocar cada skill/tool que sera usada na pipeline para
disparar TODOS os prompts de permissao em batch. Voce sera questionado
sobre cada uma; aprove para autorizar a execucao autonoma posterior.

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.

feature-00c is a command published in the GitHub repository JotJunior/cstk (23 stars, last pushed today), licensed MIT. It adds 80 tokens to every session and 19,169 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it D with 3 findings (asks for root, reads agent configuration directories, reads mcp configuration). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
