A skill-seed planter copies a starter skill from a plugin into the person's `.claude/skills/` folder, where they can edit it independently.

Use it to list available skill seeds, see which are already installed, and copy a selected seed into the current project.

It lets people adopt useful starter skills without having plugin updates overwrite their changes. It also checks for an existing skill with the same name before copying.

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	$0.00088	$0.00554
Opus 5	$0.00044	$0.00277
Sonnet 5	$0.00018	$0.00111
Haiku 4.5	$0.00009	$0.00055

Measured 12d ago against content hash 17b494a7e324, method: parsed. Prices are Anthropic first-party input rates as of 2026-09-12, from the pricing page.

Security

Grade A, and why

plantar 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 12d 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

Plantar uma semente

Semente é uma skill starter que vive no plugin só até ser plantada: copiada pra .claude/skills/ da pasta da pessoa, ela vira arquivo DELA, editável, auto-modulável, fora do alcance de qualquer atualização do plugin.

Fluxo

Listar o catálogo. As sementes vivem em ${CLAUDE_PLUGIN_ROOT}/seeds/ (se a variável não resolver, localize a pasta do plugin pm-chief-of-staff no cache de plugins). Liste as disponíveis com 1 linha de descrição cada, tirada da primeira frase do campo description do frontmatter (a linha após o título é o banner de semente, idêntico em todas, e não descreve nada). Compare com .claude/skills/ da pasta atual e marque o que já está plantado.
A pessoa escolhe (ou já veio com o nome no comando).
Checar colisão. Se já existe .claude/skills/{nome}/ na pasta dela: nunca sobrescrever. Ofereça: manter a dela (default), plantar com outro nome pra comparar, ou mostrar o diff entre as duas.
Copiar a pasta da semente pra .claude/skills/{nome}/ da pasta da pessoa. Se ela referencia .claude/skills/_shared/capacidades.md e esse arquivo não existe, diga em 1 linha que a semente vai seguir perguntando o que daria pra puxar sozinha, e ofereça rodar /pm-chief-of-staff:conectar. Existindo, nada a dizer.
Avisar: "plantada. Essa skill agora é um arquivo seu: me pede pra mudar qualquer coisa nela que eu edito na hora. Atualização do plugin nunca toca nela."

Se a pasta não tem sistema montado

Se não existe CLAUDE.md na pasta (o setup nunca rodou), diga que a semente funciona melhor plantada num sistema montado e ofereça rodar /pm-chief-of-staff:setup primeiro. Se a pessoa quiser a semente avulsa mesmo assim, plante.

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.
