Explicit tier override for the current session. Narrows or widens the exposed tool list to 'core' / 'standard' / 'full'. Prefer plan_turn(model=...) for routine per-task use; use set_tool_tier only when you need an explicit override (e.g. escalate mid-task to 'full' after a capability-gated failure).

Agent self-reports its active model identifier. Server resolves to a tier via model_tier_map (fuzzy: normalize → exact → glob → substring → '*' → 'full') and narrows the exposed tool list accordingly. Idempotent: a second call with the same model is a cheap no-op. Prefer calling plan_turn(model=...) for routine per-task use; use announce_model as a fallback when plan_turn is not appropriate for the current task.

Return the version-current CLAUDE.md / AGENT.md policy snippet for jcodemunch-mcp — the same text produced by jcodemunch-mcp claude-md --generate. Lets an agent keep a one-line CLAUDE.md (e.g. "Call jcodemunch_guide and strictly follow its instructions.") instead of pasting a static snippet that drifts from the installed version. Idempotent, no repo context required. Matches the active tool surface, tier and disabled_tools — list 'jcodemunch_guide' in disabled_tools to hide it.

Dispatch any jcodemunch action by name: order(action, args). The single-verb front door to the full tool catalog. Read-only by default — actions that change index/session state require allow_state_change=true, and execution/file-write verbs are refused. For exploration questions ('how does X work'), order('get_ranked_context', {repo, query, token_budget}) answers in ONE call — prefer it over chained search/outline/source hops; add compress=true to fit more symbols in the same budget. Call 'menu' to discover actions, or 'route' to pick one from a task.

Discover catalog actions without keeping the full tool catalog resident: menu(query?). Returns compact rows (action, summary, required args, state_changing). With no query, lists the catalog. Pair with 'order' to dispatch the chosen action.

Map a natural-language task to the best catalog action(s): route(task, repo?, execute?). Returns ranked recommendations with ready-to-run argument templates. With execute=true, dispatches the top recommendation and returns its result in the same call, collapsing discover-then-call into one round-trip. Recommends assemble_task_context / plan_turn for context-gathering intents.
