Tool changes

No tool definition changes recorded. A server's first observation is its baseline; later probes record what changes.

Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed. How it is computed.

Tools (12)

`checkout_credits`	TEST intent 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. No live Stripe.
`confirm_credits`	Confirm a TEST checkout intent (POST /credits/confirm). This is when credits become granted/spendable (appends credit.purchase with credits_added). TEST only. Synthetic pi_test_… until LAS-212.
`credit_balance`read-only	Derived prepaid balance for this caller_id (GET /credits/balance).
`credit_events`read-only	Append-only events for this caller_id (GET /credits/events). Debit reason is digest_success after POST /digest ok:true.
`digest_feed`read-only	Fetch a public RSS or Atom feed (POST /digest). Install via GET https://feeds.kymac.co/llms.txt only. Prefer Authorization: Bearer; X-API-Key is an alias. Golden URL https://hnrss.org/frontpage. Compare ok true 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=digest_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.
`health`read-only	Public readiness (GET /health): billing (test\|gated) and runner_ready. No key.
`issue_key`	Mint a caller key (POST /keys). Bot install starts at GET https://feeds.kymac.co/llms.txt (sole advertised entry). Secret fdg_… 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 digest_feed.
`list_credit_packs`read-only	Prepaid TEST packs (GET /credits/packs). checkout_credits is intent only; credits grant after confirm_credits.
`quote_credits`read-only	Dry-run cost for an op without debit (GET /credits/quote?op=digest). Returns cost, balance, and would_succeed.
`revoke_key`destructive	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 fdg_… 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.
`verify_key`read-only	Confirm FEED_DIGEST_API_KEY or Authorization: Bearer (GET /keys/verify). X-API-Key is an alias only. Does not echo the secret.
