Agentic Keychain

Describe a task in plain words and get one compact answer: whether a registry capability is worth using for it, from registry-run benchmarks only, and the next step. Use when: you have a task and no capability name, and want one decision word (use, do_not_use, use_free_alternative, insufficient_evidence, blocked_by_constraints or no_match) with its reason codes. Not for: the full arithmetic, the o

Decide whether a registry capability is worth using or buying for your task, from registry-run benchmarks only. Use when: you have a task and want a recommend, do_not_recommend or undetermined answer with the arithmetic; name a capability to weigh only that one, or leave it out and the registry weighs its closest matches. Not for: one short answer without the arithmetic (resolve_task), a plain lis

Search capability names, summaries, tasks and use-when conditions by keywords, ranked by lexical relevance only, never by payment. Use when: you want to see which capabilities exist for a topic, or you know part of a name. Not for: deciding whether one fits your task (resolve_task, or evaluate_capability for the full arithmetic) or reading a capability you can already name (get_capability). Input:

Assess two to five named capabilities side by side for the same inputs, with the same method and ak.offer.v1 offer shape as evaluate_capability. Use when: you already hold a shortlist of capability ids and want each one's decision, reasons and offer in one answer. Not for: finding candidates (search_capabilities) or a single capability (evaluate_capability). Input: the capability ids, plus the opt

Per measured model: expected saving per run, break-even runs and net saving over expected_runs, with intervals, for one capability and no task. Use when: you know the capability and want its economics on each model the registry measured. Not for: a use-or-not answer for a task (evaluate_capability) or several candidates (compare_capabilities). Input: a capability id; add model to keep one model, a

The capability's card: purpose, use-when and do-not-use-when conditions, permissions, price, evidence summary, trust checks, links and a task-independent ak.offer.v1 offer. Use when: you can name a capability and want its facts, or want to check the conditions an evaluation asked about. Not for: an answer for your task (evaluate_capability) or the full benchmark records (get_benchmark). Input: a c

Registry-run benchmark summaries (labelled), publisher claims (labelled PUBLISHER CLAIMED) and the signed attestations of one capability. Use when: you want the measurements behind an answer (paired runs, model, fixtures, method) or want to check them yourself. Not for: an answer for your task (evaluate_capability) or artifact hashes and the log proof (get_provenance). Input: a capability id, ak:/

Artifact hash, manifest hash, signed publisher and registry attestations and a transparency-log inclusion proof for one capability. Use when: you want to check that a package is the one the registry published and signed. Not for: benchmark results (get_benchmark) or the card (get_capability). Input: a capability id, ak:// URI or slug. Output: ak.provenance.v1 with the hashes, the attestations, an

A signed 15-minute price quote with the hosted checkout link. It charges nothing; a purchase requires operator approval in the hosted checkout. Use when: your operator wants the price and the checkout link of a capability that is for sale, for example after an evaluation answered recommend. Not for: deciding whether a capability is worth it (evaluate_capability); a free capability needs no quote.

Exchange the license key from the checkout (a purchase requires operator approval) for a signed entitlement and a download link that lasts at most 15 minutes. How the key is handled: the privacy page at /legal/privacy/. Repeating it with the same key is safe and never charges. Use when: your operator completed the hosted checkout and gave you the license key. Not for: a price or a checkout link (g

Report how a capability worked for you. Stored as AGENT REPORTED; it never changes evidence labels, trust or ranking. Only the listed fields are accepted; no task text is kept. Use when: you ran a capability, or decided not to, and can say whether the task succeeded. Not for: questions about a capability (get_capability, get_benchmark). Input: the capability id and success; add evaluation_id or pu
