What is retrieval-system-audit?

A comprehensive review process for improving how a system finds and returns information across its services and skills. Retrieval means matching a user's question to the right available content or operation.

Use it to audit endpoints, response formats, descriptions, search ranking, execution grounding, evaluation coverage, and weighting across sources.

It measures the existing system before changes and checks proposed improvements against live probes and reviewed test questions.

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	$0.00066	$0.01142
Opus 5	$0.00033	$0.00571
Sonnet 5	$0.00013	$0.00228
Haiku 4.5	$0.00007	$0.00114

Security

Grade A, and why

retrieval-system-audit 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 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.

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.

Retrieval System Audit

Measure the complete retrieval system before changing it. Ship only general improvements that survive real endpoint calls and reviewed golden questions.

Use the companion runbooks

Read PLAN.md, ARCHITECTURE.md, eval/EVALS.md, and eval/qa/README.md.
Use the global herdr skill to run an explicitly requested multi-model audit, one agent per pane.
Use run-evals for every evaluation run and spend decision.
Use golden-truth before changing a golden question or answer.
Use improvements-pipeline for verified upstream defects.
Use live-drift-resolution first when the committed catalog differs from the live surfaces.

Keep fixed boundaries

Treat the manifest as the exposed surface.
Keep exact operation and skill identifiers.
Keep data, soft-empty, and error responses distinct.
Keep secrets and service traffic outside model-authored code.
Do not call a paid or side-effecting service operation during inventory work.
Do not tune production behavior for one question.
Prefer deletion, simpler descriptions, and existing interfaces before new code.
Keep raw paid results local and gitignored.
Give Git, spending, deployment, and external filing authority to the coordinator.

Run the audit

1. Isolate and pin

Create a dedicated Git worktree and a round ledger under .agents/rounds/. Record the revision, clean-tree digest, manifest digest, runner digest, corpus digest, and evaluation gates.

Run the free baseline from AGENTS.md. Compile generated artifacts and verify that regeneration leaves the tree clean.

2. Build one surface ledger

Inventory every exposed operation and whole skill. Compare the committed manifest, generated specification, adapters, live catalog, and fresh-client MCP descriptions.

Record each input schema, output schema, retrieval description, retrieval profile, response class, authority scope, safety class, and evaluation coverage. Use references/evidence-contract.md for the required fields.

Files

What ships with it

2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.

retrieval-system-audit is a skill published in the GitHub repository stellar-experimental/stellar-raven (6 stars, last pushed today), licensed Apache-2.0. It adds 66 tokens to every session and 1,142 once invoked, about $0.0003 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 2026-08-31.
