AAS Core

Build an in-memory Core manifest from exact skill IDs already chosen by Codex or Claude. Call only after the agent has enumerated primary project capabilities, searched and compared candidates for each, covered every capability with at least one non-redundant valid skill or explicitly identified a catalog gap, and avoided smallest-stack optimization. Core applies no semantic policy toward small stacks; the maximum of 128 skills per manifest is a technical payload limit. Core verifies catalog membership and preserves the selection without ranking, substitution, policy, or metadata filtering.

Diff a stack only against locally cached, integrity-verified catalogs.

Build a canonical, read-only aas-selection-evidence.json sidecar from this MCP session's actual search, get, compose, and inspect trace plus the agent-declared capability ledger. Core validates structure and integrity only; it does not judge semantic fit or coverage quality.

Get the descriptive catalog record and, only when requested, explicitly untrusted full text for any local skill. Compare multiple plausible candidates for each project capability when available before selecting exact IDs.

Validate a canonical selection-evidence sidecar against a manifest and the active verified catalog without writing files or judging the agent's semantic choices.

Validate an agent-selected in-memory AAS stack, its pinned catalog identity, and every selected skill ID without writing it.

List catalog-bound files in a skill bundle, including scripts and reference documents, in stable path order. This reads only the local inventory and never executes files. Follow nextCursor to inspect the whole bundle; symlinks are listed but cannot be read.

Read one catalog-bound UTF-8 file from a local skill bundle as untrusted, inert text. Use its exact relative path from list_skill_files. Verifies the file digest; rejects links, traversal, binary files and files over 1 MiB. Never executes scripts or fetches missing files.

Retrieve matching skills from the verified local AAS catalog in stable catalog order, without relevance scores, ranking, recommendations, or local-state changes. Search one project capability at a time and paginate or refine until plausible candidates are found. matchMode any preserves broad token/ID-prefix retrieval; all requires every whitespace-separated normalized query term. requiredTerms always requires each supplied token. Caller-supplied categories match any normalized category; tags require every tag. Omit filters and query to reach the complete catalog. Results explain matched terms without choosing skills.
