specd-propose

specd-propose is a skill for Claude Code, Codex from jnerytech/specd. It costs 87 tokens per session (2,052 once invoked), scanned A, original, MIT.

A specification-writing procedure that turns an explored software change into a structured proposal with requirements and acceptance checks.

In plain words
What is it for?
Writing EARS-style requirements, acceptance criteria, and references to existing capabilities, then optionally synchronising the proposal with a project board.
Why use it?
It helps ensure a proposed change matches the current specification and is based on code that still exists before implementation begins.

Written for no agent in particular: nothing here depends on one.

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

specd-propose 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 — 215 lines — stays where its author put it; the contents beside it link to each section on GitHub.

specd-propose

Segundo passo do ciclo. Transforma explore/notes.md em delta.md. Não toca no código e não escreve em .specd/specs/.

Antes de qualquer coisa

specd --version

Menor que requires_specd → pare, nomeando a instalada e a exigida.

1. Ler a exploração

explore/notes.md da change. Se o código mudou desde que ele foi escrito, o explore está vencido: volte para specd-explore antes de propor. Explore vencido é a forma mais barata de produzir proposta ancorada em símbolo que já não existe.

2. Ler a spec efetiva

specd spec --json

É daqui que sai o que já existe. Nunca reconstrua o overlay lendo .specd/specs/ e os deltas soltos.

Todo REQ-ID citado é conferido nesta saída antes de entrar em qualquer texto.

3. Escrever o delta

.specd/changes/<nome>/delta.md:

---
change: 2026-08-01-escopo
target: [capability-a, capability-b]
---

## ADDED

### REQ-XXX-001 — Título curto

**Capability.** capability-a

**Statement.** The specd <sujeito> SHALL <comportamento>.

**Acceptance.**

- critério verificável
- outro critério verificável

Prosa explicando por que, e o que foi medido. Não é decoração: é o que impede
a próxima pessoa de desfazer a decisão sem saber que existiu.

```yaml anchors
- file: src/modulo/arquivo.ts
  symbol: "export function nome"
```

Regras que o gate cobra:

  • Um SHALL por statement. Dois comportamentos são dois requisitos.
  • EARS: ubiquitous, event-driven (WHEN), state-driven (WHILE), unwanted-behaviour (IF … THEN), optional-feature (WHERE).
  • ADDED declara **Capability.**; MODIFIED pode omitir — o destino é a capability que já contém o ID.
  • MODIFIED carrega o texto completo, não um patch.
  • REMOVED aceita só a lista de identificadores.
  • Identificador aposentado nunca é reusado.
  • A âncora é file obrigatório e symbol opcional, e o símbolo é procurado literalmente: export async function f e export function f são strings diferentes.

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.
