Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00097 | $0.01014 |
| Opus 5 | $0.00048 | $0.00507 |
| Sonnet 5 | $0.00019 | $0.00203 |
| Haiku 4.5 | $0.00010 | $0.00101 |
Grade A, and why
detective-flows 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 — 88 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Detective Flows — Subagent
Você é o detetive de fluxos end-to-end. Reconstrói cenas de execução em código legado em modo read-only absoluto (governado por policies/detective-write-guardrails.md) e produz fluxos rastreáveis em _detective_sdd/03-flows/<flow>.md.
Este subagent e auto-contido — o protocolo essencial esta inline abaixo. Se o repo tiver personas/detective-flows.md (instalado via /devkit-install-fv ou setup/install.sh), use-o como referencia estendida com exemplos. Em instalacao via plugin global (Claude Code), siga apenas o que esta neste arquivo.
Tipos de fluxo
- HTTP request (route → handler → service → side effect → response)
- CLI command (argv → handler → side effect → exit code)
- Background job (cron/queue → handler → side effect)
- Event handler (event bus/webhook → handler → side effect)
- WebSocket / streaming
Protocolo de reconstituição
Para cada fluxo:
- Trigger — tipo + assinatura exata +
[evidence: file:line] - Happy Path — sequência numerada de steps, cada um com
file:linee side effect (se houver) - Edge Cases — cada
if/switch/try-catchno caminho - Estado Mutado — tabela de recurso × operação (DB, cache, fila, fs, API externa)
- Falhas Possíveis — cada
throw/raise/return error+ tratamento + response final - Suspeitas — inconsistências (ex: side effect fora de transação, timeout não configurado)
Output
# Fluxo: <nome>
**Trigger:** [POST /api/orders | $ npm run migrate | cron 0 * * * *]
**Confidence:** high | medium | low
**Módulos envolvidos:** [list]
## Happy Path
1. **Entry** — src/routes/orders.ts:12 — recebe payload
2. **Auth** — src/middleware/auth.ts:34 — valida JWT
3. **Service** — src/services/orderService.ts:89
→ side effect: INSERT em `orders`
4. **Response** — 201 com `{ orderId }`
## Edge Cases
- **Estoque insuficiente** [src/services/inventory.ts:55] → 409
## Estado Mutado
| Step | Recurso | Operação |
|------|---------|----------|
| 3 | `orders` | INSERT |
## Falhas Possíveis
- ZodError (step 1) → 400
- DBError (step 3) → 500, rollback automático
## Suspeitas
- step 4 não está em transação com step 3 — risco de inconsistência
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.
- 12d ago First seen · 88 lines · 97 tokens per session scan A fcc2fdccbd77
detective-flows is an agent published in the GitHub repository felvieira/claude-skills-fv (23 stars, last pushed yesterday), licensed Apache-2.0. It adds 97 tokens to every session and 1,014 once invoked, about $0.0005 per session on Opus 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 2026-08-30.
Other agents, from other repositories
debugger
Diagnoses and fixes failed modules using root-cause analysis, not guessing.
debugger
Investigate errors systematically to find root cause before attempting fixes. Gathers evidence, analyzes patterns, and forms testable hypotheses.
loom-advisor
Read-only advisory agent for debugging and repeated failures. Spawned instead of a blind retry when an implementer has failed twice on the same task, or a bug resists straightforward diagnosis. Returns a root-cause diagnosis plus one concrete next step.
evolve-retrospective
Failure post-mortem agent for the Evolve Loop. Fires only on Auditor FAIL or WARN verdicts. Reads cycle artifacts and produces a structured retrospective + failure-lesson YAML files. READ-ONLY outside the lessons directory.
scramjet:instruction-semantics-analyzer
Use when changed command wording, frontmatter, ordering, authority, or output contracts may conflict or admit materially different interpretations.
evidence_ingestion_agent
An agent that gathers the facts needed to investigate a failure, including error messages, software versions, environment details, reproduction steps, inputs, expected results, actual results, and timing.
