- freshness: 85

## Quality 87/100 (good)

### protocol: 88 (weight 25)

- pass `protocol.modern`: supports 2026-07-28 (server/discover)
- pass `protocol.stateless`: answers without a session
- pass `protocol.transport`: streamable HTTP
- warn `protocol.list_ttl`: tools/list carries no ttlMs, so clients re-fetch it

### authorization: n/a (weight 15)

- n/a `auth.prm`, `auth.as_metadata`, `auth.cimd`: no remote uses OAuth
- n/a `auth.secret_in_url`: no templated URL

### tool hygiene: 86 (weight 30)

- pass `tools.descriptions`: every tool has a description
- pass `tools.description_length`: descriptions are concise
- pass `tools.schemas`: every tool has an object input schema
- pass `tools.annotations`: 12 of 12 tools declare readOnlyHint or destructiveHint
- fail `tools.directory_hints`: no tool declares all four of readOnlyHint, destructiveHint, idempotentHint and openWorldHint; missing: confirm_credits (idempotentHint, openWorldHint); smoke (idempotentHint, openWorldHint); issue_key (idempotentHint, openWorldHint); …
- pass `tools.token_cost`: about 1,033 tokens to load every tool
- pass `tools.api_dump`: tools are not a one-to-one API dump

### stability: n/a (weight 15)

- n/a `stability.changes`, `stability.rug_pull`: tool history not recorded yet

### dependencies: n/a (weight 15)

- n/a `deps.known_vulns`, `deps.mcp_sdk_version`, `deps.resolvable`: no npm or PyPI package

- tools: 12, about 1,033 tokens to load them all
- tool set hash: 60b0ef339893e37d4e7ca2b94752cce6
- badge: [![protogrid quality](https://protogrid.dev/badge/co.kymac.shelf/shelf-smoke.svg)](https://protogrid.dev/servers/co.kymac.shelf/shelf-smoke)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

## Tools (12)

- `checkout_credits`: Stripe TEST PaymentIntent for a pack (POST /credits/checkout). Intent only — returns credits_pending; credits are not granted or spendable until confirm_credits succeeds. Requires a caller key.
- `confirm_credits`: Confirm a TEST PaymentIntent with Stripe test card pm_card_visa (POST /credits/confirm). This is when credits become granted/spendable (appends credit.purchase with credits_added). TEST only.
- `credit_balance`: Derived prepaid balance for this caller_id (GET /credits/balance).
- `credit_events`: Append-only Ledger events for this caller_id (GET /credits/events): credit.grant (first_key), credit.purchase, credit.debit, optional credit.balance_snapshot.
- `health`: Public readiness (GET /health): billing (test|live|gated) and runner_ready. No key.
- `issue_key`: Mint a caller key (POST /keys). Bot install starts at GET https://shelf.kymac.co/llms.txt (sole advertised entry). Secret ssm_… is returned once. Prefer Authorization: Bearer; X-API-Key is an alias. First issue grants 1 free credit (credit.grant reason=first_key). Quote cost with quote_credits before smoke.
- `list_credit_packs`: Prepaid TEST packs (GET /credits/packs). checkout_credits is intent only; credits grant after confirm_credits.
- `quote_credits`: Dry-run cost for an op without debit (GET /credits/quote?op=smoke). Returns cost, balance, and would_succeed.
- `revoke_key`: Invalidate the presented secret (POST /keys/revoke). Same id is revoked; old secret then fails 401 invalid_api_key. Prefer Authorization: Bearer; X-API-Key is an alias only. No ops file-edit.
- `rotate_key`: Replace the presented secret (POST /keys/rotate). Same id/caller_id and credits. New ssm_… is returned once. Old secret then fails 401 invalid_api_key. Prefer Authorization: Bearer; X-API-Key is an alias only. No ops file-edit.
- `smoke`: Headless smoke (POST /smoke). Install via GET https://shelf.kymac.co/llms.txt only. Prefer Authorization: Bearer; X-API-Key is an alias. Golden URL https://example.com/ — compare ok true/false JSON in llms.txt. First key includes 1 free credit. Quote first with quote_credits (no debit). Debits 1 credit on ok:true (credit.debit reason=smoke_success). 200 bodies include credits_burned and credits_remaining. HTTP fails use code/message/retryable/next (error aliases message). 401 next=refresh key. 402: code=insufficient_credits, retryable=false, next=buy credits. Retryable fails use next=retry.
- `verify_key`: Confirm SHELF_SMOKE_API_KEY or Authorization: Bearer (GET /keys/verify). X-API-Key is an alias only. Does not echo the secret.
