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 | $0.00045 | $0.01430 |
| Opus 5 | $0.00023 | $0.00715 |
| Sonnet 5 | $0.00009 | $0.00286 |
| Haiku 4.5 | $0.00005 | $0.00143 |
Grade B, and why
ag-otimizar-harness scanned grade B 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.

ag-otimizar-harness — Otimizador do harness
Complementa
ag-auditar-harness(que diagnostica) com acoes de otimizacao de custo/performance: caching, depreciacao, MCP slimming.
Quando invocar
- Sob demanda:
/ag-otimizar-harness - Como sub-fase de
/ag-13-limpar-codigo --target=harness - Como recommendation gerada por
ag-auditar-harness(HCS.mcp_cost baixo) - Trimestral via
ag-curador-skills
Output
Relatorio em ~/Claude/docs/diagnosticos/harness-optimization-YYYY-MM-DD.md.
Se --apply: PR atomico com markers cache_control: ephemeral aplicados + skills marcadas como deprecated: true.
4 Analises
1. cost_per_skill — Top skills por custo total
Fonte: ~/.claude/projects/*/session-*.jsonl (ultimos 30 dias).
Metodo:
- Para cada skill invocada (
tool_usecomname=Skill):- Soma
usage.input_tokens+usage.output_tokensda assistant message subsequente - Conta invocacoes
- Soma
- Ranking:
tokens_total = mean(tokens_por_invocacao) * invocacoes
Output: Top 10 skills caras com decomposicao mean vs frequency.
2. cache_candidates — Skills elegiveis para cache_control
Criterios (do prompt-cache-policy.md):
- Tamanho >= 300 linhas
- Conteudo estatico (sem timestamp, IDs, paths dinamicos)
- Invocada >= 2x por sessao tipica
Metodo:
wc -lem cada SKILL.md- Detecta dinamico: grep
{{,\$ARGUMENTS,\$(date,\$(uuidgenetc. - Cross-check com
cost_per_skill(frequencia >= 2) - Para cada candidato:
- Sugere ponto de insercao do marker (apos primeiro
##longo) - Calcula tokens economizados estimados (~tokens_per_invocation * (invocacoes - 1) * 0.9)
- Sugere ponto de insercao do marker (apos primeiro
Action --apply: insere <!-- cache_control: ephemeral --> no ponto sugerido.
Reusa logica do ag-otimizar-cache existente — esta skill orquestra, nao reimplementa.
3. dead_skills — Skills com 0 invocacoes em N dias
Default N=90 dias.
Metodo:
- Lista todas as skills (
ls ~/Claude/.claude/skills/) - Para cada: grep no transcripts dos ultimos 90 dias
- Skills com 0 invocacoes:
- CONFIRM antes de depreciar:
- Tem
metadata.always_available: true? → skip - E referenciada por outra skill (
[[name]]em outro SKILL.md)? → skip - Foi criada nos ultimos 30 dias? → skip (ainda em adocao)
- Tem
- CONFIRM antes de depreciar:
- Sugere depreciacao via
metadata.deprecated: true+ nota de migracao
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.

ag-otimizar-harness is a skill published in the GitHub repository andregusman-raiz/a-gusman-claude (19 stars, last pushed 4d ago), licensed MIT. It adds 45 tokens to every session and 1,430 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it B with 1 finding (enumerates other installed skills). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
Other skills, from other repositories
taiyi-ui-design
A design-planning guide for describing how an application's user interface should look and behave. It produces a UI-DESIGN.md document covering layouts, components, interactions, accessibility, and error states.
taiyi-evolve
A workflow skill that compares the implemented code with the frozen design after development and testing. It records architecture changes and proposes updates to DESIGN.md, the document describing the intended system structure.
taiyi-diagram-c4
A code-scanning tool that builds C4 architecture documents from a repository. It separates facts observed in the code from conclusions inferred about the design and uses Mermaid diagrams as the source format.
retrospective-audit
Stage B of /prflow:retrospective-weekly: given a most-recent-first subset of one recurring pattern's occurrence-PR context bundles (bounded by auditbundlecap), re-derive the root cause and return one JSON object carrying a ranked findings array (one to three sub-patterns) — no edits, no worktree. Invoked as a subagent…
docs
Use when documentation generally needs to catch up with a branch before pushing or merging, covering internal developer docs, external customer-facing docs, and release notes together — "update the docs", "do a docs pass before I merge", "make sure everything's documented". Prefer this when no single documentation…
tmux-lane-orchestrator
Manage one tmux agent lane from its matching ops pane, inspect live pane state and Codex logs on cold start, and produce concise manager summaries for OpenClaw and adjacent project work.
