specd-apply-change

specd-apply-change is a skill for Claude Code, Codex from jnerytech/specd. It costs 77 tokens per session (1,012 once invoked), scanned A, original, MIT.

A workflow for implementing the tasks in an open specd change until its requirements and acceptance checks are satisfied. A change is a tracked set of proposed project modifications.

In plain words
What is it for?
Use it to select an open change, implement its pending tasks, update its delta, and run the specd verification report.
Why use it?
It keeps implementation tied to the written requirements, records discoveries, and verifies the result before the work is considered complete.

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

specd-apply-change 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.

How it starts

The opening of the file, as written. The whole thing — 107 lines — stays where its author put it; the contents beside it link to each section on GitHub.

specd-apply-change

Terceiro passo do ciclo. Implementa até o gate fechar. Não arquiva, não escreve no board e não promove requisito para .specd/specs/.

Antes de qualquer coisa

specd --version

Menor que requires_specd → pare.

1. Escolher a change e a task

specd status --json

Uma change aberta: use essa. Mais de uma: pergunte pela ferramenta de pergunta do host com as changes como opções. Nunca infira por data nem por ordem.

Dentro da change, as tasks estão em tasks/*.md com status na frontmatter: pending | in_progress | done | blocked.

2. Ler o contrato

specd spec --json

Os requisitos que a task cita em req são a especificação. Os critérios de aceite são a especificação de teste — cada um vira teste.

Nunca reconstrua o overlay lendo .specd/specs/ e os deltas soltos: a spec que a skill leria não seria a que o gate lê, e ninguém veria a diferença.

3. Implementar

Até as âncoras declaradas no delta resolverem. A âncora é contrato, não sugestão: respeite exatamente o caminho e o símbolo declarados. Se o símbolo precisar de outro nome, atualize o delta no mesmo commit — requisito em voo é maleável e o preço é cobrado na hora.

Escreva código no idioma e no estilo do repositório em volta: mesma densidade de comentário, mesmos nomes, mesmos idiomas.

4. Atualizar a spec com o que a execução descobriu

"A spec" aqui é o delta, nunca .specd/specs/. Requisito que faltava, âncora que devia apontar para outro símbolo, premissa que não se sustentou: tudo entra no delta.md da change corrente.

É para isso que o delta é a superfície de escrita — o ciclo precisa de um lugar onde a realidade corrige a intenção sem contaminar a verdade realizada.

Mexeu em requisito? Confira se o req das tasks acompanha, ou coverage reprova.

Nunca toque no propose.json. Ele é o registro do que a proposta dizia, e é contra ele que a specd-archive-change recorta a revisão. Reescrevê-lo aqui faria o recorte dar vazio sempre — o mecanismo inteiro viraria decoração, e a revisão que ele sustenta passaria a informar que nada mudou justamente nas changes em que mais coisa muda.

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.
