What is agente-00c-runtime?

A collection of internal POSIX shell helpers for managing workflow state, locks, validation, hashes, paths, and secret filtering. POSIX shell is a portable command-line scripting standard.

Supporting agente-00c workflows with state files, history, locking, integrity checks, path validation, and secret filtering.

It gives orchestrated workflows consistent ways to read, write, validate, and protect their saved state.

agente-00c-runtime — Skill for Claude Code by JotJunior

Install

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.

Any agent

npx skills add JotJunior/cstk --skill agente-00c-runtime

Clone the repo

git clone --depth 1 https://github.com/JotJunior/cstk

Made for: Claude Code.

Or install cstk, the plugin that ships this one along with the rest of its 21 skills, 7 commands, 7 agents, 1 MCP server.

NVIDIA SkillSpector warn 7 Sept 2026

SkillSpector: 1 finding, up to medium

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 →

medium Rogue Agent · line 21
Skill establishes unauthorized persistence across sessions via cron jobs, startup scripts, or state files. Session persistence allows an attacker to maintain access beyond the current interaction.

Fix: Remove any persistence mechanisms (cron jobs, startup scripts, state files). Skills should not maintain state across sessions without explicit user consent.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00042	$0.04054
Opus 5	$0.00021	$0.02027
Sonnet 5	$0.00008	$0.00811
Haiku 4.5	$0.00004	$0.00405

Security

Grade A, and why

agente-00c-runtime 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 5d ago.

The scan reads SKILL.md. This mod also ships 51 executable files (hooks/posttooluse-agent-usage.sh, hooks/posttooluse-loose-usage.sh, hooks/posttooluse-tool-call-tick.sh, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

Agente-00C Runtime

Scripts POSIX que implementam as primitivas de estado da pipeline 00C. Consumidos via tool Bash pelos agentes em ~/.claude/agents/agente-00c-*.md.

Layout

~/.claude/skills/agente-00c-runtime/
└── scripts/
    ├── state-rw.sh        # init/read/write/get/set/sha256/path-validate
    ├── state-validate.sh  # FR-008: schema + invariantes (read-only)
    └── state-lock.sh      # acquire/release/check (mkdir atomico)

Convencao de path do estado

<projeto-alvo>/.claude/agente-00c-state/
├── state.json
├── state.json.sha256
├── .lock/                 # diretorio criado por mkdir atomico
└── state-history/
    └── onda-NNN-<iso8601>.json

Todos os scripts aceitam --state-dir <path> apontando para o diretorio acima — nao para o state.json diretamente.

Dependencia: jq

Os helpers de leitura/escrita de state.json exigem jq no PATH. Sem jq, os scripts falham com mensagem clara orientando instalacao (brew install jq no macOS / apt install jq em Debian/Ubuntu). Esta e uma excecao escopada ao Principio II do toolkit (POSIX sh puro), alinhada com o carve-out 1.1.0 da constitution para JSON estruturado.

NAO e skill user-invocavel

Esta skill NAO tem trigger automatico — description indica claramente que e infraestrutura interna. Nao deve aparecer como sugestao para o operador. A presenca em ~/.claude/skills/ e necessaria apenas porque o mecanismo de cstk install so distribui artefatos sob plugins/cstk/skills/, plugins/cstk/commands/ ou plugins/cstk/agents/.

Estado atual

FASE 2 do backlog em docs/specs/_archived/agente-00c/tasks.md. Implementacao operacional dos 3 scripts entregue como esqueleto + cobertura de testes em tests/test_state-*.sh.

Reuso pelo feature-00c (FASE 1 de `docs/specs/_archived/feature-00c/tasks.md`)

Este runtime e compartilhado entre /agente-00c (orquestracao de projeto inteiro) e /feature-00c (orquestracao de feature individual). Auditoria empirica em scripts/_audit-paths.md confirma que 18/21 scripts ja aceitam --state-dir DIR desde a v1.0 — nenhum refactor mecanico necessario. Os 3 scripts restantes (issue.sh, report.sh, secrets-filter.sh) tem decisoes de design documentadas no audit.

What ships with it

60 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.

agente-00c-runtime is a skill published in the GitHub repository JotJunior/cstk (23 stars, last pushed today), licensed MIT. It adds 42 tokens to every session and 4,054 once invoked, about $0.0002 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 2026-08-30.
