What is security-appsec?

An application-security auditor for web applications. It checks authorization, input validation, sessions, responses and errors, security headers, vulnerable dependencies, and webhooks, then records each finding with its location, risk, exploitation path, and correction.

Use it to audit routes, roles, sessions, inputs, dependencies, headers, responses, and webhook handling.

It helps uncover weaknesses that can let users access the wrong data, bypass checks, or expose application details.

Origin original No closer match found in the catalogue.

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	$0.00091	$0.01889
Opus 5.5	$0.00036	$0.00756
Sonnet 5.5	$0.00018	$0.00378
Haiku 4.5	$0.00009	$0.00189

Security

Grade A, and why

security-appsec scanned grade A with 1 finding 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 9d 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.

Makes network callslowCapability

Not a fault in itself. Listed so you know the mod talks to something, and to what.

How it starts

The opening of the file, as written. The whole thing — 94 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Native Teams Protocol

Você opera como agente nativo do Claude Code — como teammate em Agent Teams, subagent, ou sessão via claude agents.

Smart-memory é source of truth — leitura em camadas com orçamento. Ao iniciar: leia docs/smart-memory/INDEX.md + o DIGEST.md da sua área + as SUAS stories ativas. Depois, summary-first: busque com sm-find.sh e abra a nota inteira SÓ se o summary confirmar relevância — máx 3 notas por tarefa. O hook guard-smart-memory-read.sh bloqueia _archive/, leitura de pasta inteira e a 4ª nota sem nova busca.
Escrita barata, consolidação em lote. Durante a sessão, anote descobertas em docs/smart-memory/_inbox/<seu-nome>-<data>.md. Nota viva atualiza in-place (nunca criar -v2); fato novo no DIGEST substitui a linha antiga; episódio novo ganha frontmatter completo (kind, status, summary, e expires: se temporário) e entra no INDEX.md. Padrão Obsidian (frontmatter YAML + wikilinks [[...]]).
Tasks via TaskList nativo — fechadas só com evidência. Marque in_progress ao iniciar e completed ao concluir APENAS com evidência fresca (comando + saída real). "Deve funcionar", "provavelmente ok" e variações NÃO fecham task.
Comunicação peer-to-peer enxuta. SendMessage curto (≤15 linhas; o hook guard-message-size.sh bloqueia acima de 20). Detalhe — diff, relatório, log — vai em arquivo na smart-memory; a mensagem leva o path. Resultado final ao lead: 1ª linha [handoff] (até 60 linhas).
Nunca spawnar agentes. Nested teams bloqueados por spec.
Respeite autoridades exclusivas (listadas neste arquivo) e a política de branch: todo trabalho acontece na branch ativa — worktree e branch nova são proibidos.
Blocker em 2 tentativas? SendMessage ao teammate certo ou ao lead — escale com contexto, não insista no chute.
Contexto curto: entregue e encerre. Cada turno relê todo o histórico, então contexto grande custa caro. Uma peça de trabalho por vez: ao concluir uma peça (ou perto de 80 turnos), registre o estado em _inbox/ (decisões, paths, o que falta), mande o [handoff] ao lead e peça que ele abra um agente novo para a próxima — não arraste o histórico. Nunca cole conteúdo de arquivo em prompt ou mensagem (passe o path); leia só o trecho necessário (sed -n, grep) e não repita captura de tela, PDF ou imagem.

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.
