implement-plan

implement-plan is a skill for Claude Code from Joaonic/agentkit. It costs 19 tokens per session (4,884 once invoked), scanned A, original, MIT.

Instructions for carrying out an existing software-development plan through separate, sequential subagents. They define required workflow stages, reviews, file access, tests, and validation responsibilities.

In plain words
What is it for?
Use them when implementing an approved plan that requires worktrees, staged coding, code review, user-interface review, testing, or documentation.
Why use it?
They prevent an agent from skipping governance steps or making changes directly when the workflow requires controlled delegation. This makes execution easier to review and verify.

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

implement-plan 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 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.

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.

LEIA ESTA SKILL COMPLETAMENTE ANTES DE COMEÇAR

Implementar um plano existente. Não cria plano. Sempre numa worktree separada.

Fonte única:

  • docs/governance/cursor/workflow.md
  • docs/governance/cursor/workflow/*.md

Contrato operacional obrigatório desta skill:

  1. Você é o agente pai e atua apenas como orquestrador.
  2. Você não pode usar diretamente Read, Write, Edit, MultiEdit, Shell, Grep, Search, Browser, MCP, ferramentas de VCS remotas, Web, testes, ou qualquer outra tool fora da tool de subagent.
  3. Todo acesso a ficheiros, comandos, GitLab/GitHub (tracker), MCP, web, testes e validações deve acontecer dentro de subagents.
  4. A execução é obrigatoriamente sequencial. Uma etapa por vez.
  5. Cada chamada de subagent deve definir explicitamente subagent_type.
  6. Cada chamada de subagent deve incluir o marcador exato da etapa no prompt ou na description.
  7. Não pular etapas obrigatórias.
  8. Após workflow:code-review, cumprir sempre workflow:ux-review. Com alteração em fluxos ou superfície user-facing sob web/** (ou outro frontend definido no subprojeto), usar ux-reviewer. Sem alteração user-facing, usar verifier ou docs para registar «UX Review: não aplicável (sem frontend)» — não invocar ux-reviewer (rule 08-ux-mandatory.mdc).
  9. O ux-reviewer (e a etapa workflow:ux-review) não substituem workflow:posttask.
  10. Antes de declarar concluído, cumprir a skill posttask, MR pareado (GitLab) ou PR (exceção GitHub), review-open-pr e CI verde conforme o workflow do projeto.

Política de zero tolerância (obrigatória em todas as etapas):

  1. Não existe "aprovado com ressalvas" — qualquer problema encontrado em scope (código, testes, UX, docs, acessibilidade) é BLOQUEANTE e deve ser resolvido antes de avançar.
  2. Se o code-reviewer ou ux-reviewer reportar problemas, o agente pai deve delegar correção ao subagent adequado e re-submeter para review até zero problemas restarem.
  3. Problemas de UX em ficheiros tocados são bloqueantes quando há mudança user-facing em web/** (ou frontend do subprojeto em causa).

Uso obrigatório de MCP para pesquisa:

  1. Subagents de workflow:investigation, workflow:implementation e workflow:code-review devem usar Context7 (servidor MCP configurado no projeto) para validar APIs/bibliotecas contra documentação actualizada (Spring Boot, React, Next.js, Flyway, MapStruct, etc.).
  2. Quando existirem outros MCPs oficiais em .cursor/mcp.json para integrações em scope, usá-los em vez de suposições de treino.
  3. Nunca depender apenas de training data para APIs/bibliotecas quando MCP aplicável estiver disponível.

Regras obrigatórias de CI (aplicar em todas as etapas que envolvam push/CI):

  1. CI RED é BLOQUEANTE — nenhuma etapa avança com checks falhados. Corrigir antes de prosseguir.
  2. CI CANCELLED == CI FAILED — pipeline fail-fast cancela jobs satélite. Nunca reexecutar pipelines sem corrigir causa raiz. Em GitLab: glab ci list --ref <branch>, depois glab ci trace <job-id> no job que falhou primeiro. Em GitHub Actions (ex.: web/your-github-project): gh run view <id> --json jobs e gh run view <id> --log-failed.
  3. Bugs encontrados durante code-review ou posttask são BLOQUEANTES — o agente pai delega correção e re-submete até zero problemas.

Regras obrigatórias de rebase/merge (NUNCA perder código):

  1. Ao fazer rebase ou merge de main na branch de trabalho, NUNCA perder conteúdo que já existia em main. O rebase serve para incorporar main — não para sobrescrever.
  2. Durante resolução de conflitos, ambos os lados devem ser preservados: o código novo da feature E o código existente de main. Se houver conflito real (mesmo trecho modificado nos dois lados), o agente deve fundir manualmente, mantendo a semântica de ambos.
  3. Após rebase, o agente deve verificar: git diff origin/main..HEAD -- <ficheiros com conflito> e confirmar que nenhuma funcionalidade, import, teste, config ou bloco de código de main desapareceu.
  4. Se o agente detectar que perdeu código de main durante rebase, deve imediatamente corrigir (cherry-pick, re-apply, ou editar manualmente) antes de avançar para qualquer outra etapa.
  5. Esta regra aplica-se a todas as etapas: investigation, implementation, code-review, posttask — sempre que houver rebase/merge de main.

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.

implement-plan is a skill published in the GitHub repository Joaonic/agentkit (2 stars, last pushed 5mo ago), licensed MIT. It adds 19 tokens to every session and 4,884 once invoked, about $0.0001 per session on Opus 5.5. 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.
