Knowledge Query

Ask a question against a bound cogni-knowledge base. This skill is the shallow rung of the query↔research depth ladder: it ranks the pages that cover the question, reads them, and synthesizes a grounded, cited answer — one question, index-first, ≤12 pages, no web, no verify (the deep wiki-only report rung is owned by knowledge-compose --source wiki).

It runs natively on the vendored wiki engine — it consumes the shared wiki-grounding.py discovery primitive directly and reads the wiki pages with the Read tool, so a Karpathy base answers questions without cogni-wiki installed. The cogni-knowledge value-add:

1. Binding-aware wiki path resolution — no --wiki-root from the user; read from binding.json.
2. Index-first grounded synthesis — rank covering pages via wiki-grounding.py, read them, answer only from what they say (with [[slug]] citations), and report honestly when coverage is thin.
3. Knowledge-base footer — every answer ends with one line tying it to the knowledge slug + deposit count + fetch-cache health, so the user remembers where the answer came from and how much evidence the base holds.

Read ${CLAUDE_PLUGIN_ROOT}/references/differentiation-thesis.md once per session to anchor on the accumulation thesis. The synthesis discipline below — answer only from the pages you read, cite every claim, admit uncertainty — is the shallow rung's core contract.
