Extracted from the reflex spike (feat/needle), keeping only the measured winner: pure BM25 ranking behind discovery::search_functions, plus the gated pre-generate search hint (inject_hint knob, hot bind/unbind) and the console surface (search call card, config form with live hint preview, null transcript renderer). Carries the additive @iii-dev/console-ui typings + SOP section for the optional chat.registerTranscriptRenderer slot the worker feature-detects; the console implementation of that slot stays on feat/needle. Evidence for bm25-only lives in docs/reflex-discover-findings.md.
…nerate hooks Dynamic pre-generate hooks (discovery::pre-generate) need the concrete decision surface to gate on: split build_tools into concrete_allowed_tools (one schema per allowed registry function, what hooks reason over) and provider_tools (the agent_trigger envelope or the concrete list, what the model sees), and include functions_generation, tools, and expose in the hook's generate payload. Without these fields the discovery worker's request deserialization failed on every pass and on_error=fail_open swallowed it — the hint never reached a single generation.
…essage Both gates scanned the whole context window, so turn 1's worker results (already_operating) or a function id named in turn 1 (task_guided) suppressed the hint for every later turn — even when turn 1 never searched and the next task needed new capabilities. Evidence now resets at the latest user message: exclusive slice for operating evidence, inclusive for guidance (the guiding text usually IS that message). AlreadySearched stays whole-window by design: a search result in the window means the contracts are already known.
… on empty search When a search matches no installed function, consult the public worker registry (directory::registry::workers::list with the full query, then per-term retries — pg_trgm misses long natural-language queries that a single term lands), pull the top verified candidates' API references, rank all pooled contracts against the full query in one shared BM25 pass, and return up to two workers as an `installable` section with install guidance (worker::add source kind=registry, wait:false, poll worker::status). Verified authors only; functions already installed, internal, or in excluded namespaces never surface. Fail-open: any registry error falls back to the plain refine guidance. New hot config knob `registry_fallback` (default on) disables the whole path.
…arch card The call card now parses the response's optional `installable` section: an INSTALLABLE meta chip, one section per registry worker (name @ version, a NOT INSTALLED tag, description, its matched contracts as the usual collapsible ƒ rows) and the exact worker::add install call. The empty state keeps the old refine text only when nothing installed AND nothing installable matched; guidance stays behind the collapsed details row instead of dumping into the card.
The installable section now rides along every search response instead of only the empty ones: registry list variants (full query + informative terms, cap 6) run CONCURRENTLY via JoinSet so a cold registry costs one timeout, candidates merge round-robin across variants so a multi-intent query's later capability is not starved out of the cap by the first one's lookalikes, and candidates matching an already-installed namespace are skipped. Combined guidance keeps the installed contracts authoritative and marks installable ones as prefer-installed + confirm-before-worker::add. Knob renamed registry_fallback → registry_search (serde alias keeps stored values), now with a config-form checkbox (previously missing).
The one-shot lexical function search, the conditional pre-generate hint,
and the installable-registry search move into iii-directory; the
standalone discovery worker is deleted (hard removal, no aliases).
Public id: discovery::search_functions → directory::search_functions.
Internal ids: directory::{pre-generate,on-functions-change,hint-preview};
the separate discovery config entry and on-config-change handler fold
into the existing iii-directory entry (knobs inject_hint,
hint_min_workers, registry_search — tunable, hot-reload, with
config-form fields). The hook's transcript annotation key becomes
origin.directory.
The registry search now runs in-process through functions/registry.rs
(worker_list/worker_info + RegistryCache) instead of round-tripping
directory::registry::workers::* through the engine — the cross-worker
hop, its per-call timeout, and the extra permission dependency collapse.
Search exclusion is by function, not namespace: engine::* and
metadata.internal functions never enter the catalog, the search excludes
itself, and the retired reflex:: prefix dies — which makes the worker's
own public directory::* functions searchable like any other capability
(verified live: skills/prompts/registry functions rank, internals never
leak).
BREAKING: the discovery worker and its discovery::* ids no longer exist;
sessions relying on discovery::search_functions must use
directory::search_functions. iii-sdk pinned =0.21.8 (was =0.21.6);
iii.worker.yaml gains the harness ^1.0.0 dependency for the hook.
Verified: 328 lib tests + golden schemas + clippy clean; UI tests/build
green; live on the workers-dev stack — combined installed+installable
search, hook binding re-armed, hint injected once per session with the
model's first call being directory::search_functions, and
discovery_assist.guided/.open PASS 100/100.
Live sessions showed models calling an installable function directly
(web::fetch, not installed → function_not_found) even though the
guidance said not to — an uninstalled contract that LOOKS like a
callable contract invites exactly that pattern-match. Three structural
changes:
- installable functions now carry name + description ONLY (no
request_schema): there is nothing to shape a direct call from, and
the real contracts arrive through a fresh search after installing.
- every installable worker carries a ready-made call envelope
({ function: "worker::add", payload: { source: { kind: "registry",
name }, wait: false } }) — models follow concrete envelopes far
better than prose instructions.
- the guidance is imperative: calling these now FAILS with
function_not_found; run the install call, poll worker::status until
running, then search again.
The card renders installable functions as plain ƒ rows (no schema
toggle). Verified live: the g1 task that previously stumbled on
web::fetch now goes search → browser::fetch (installed) in two calls.
The fn-id column collapsed to minimum width under flex + break-all and rendered ids one character per line (web::fetch → we/b::/fet/ch). The id no longer shrinks or breaks; the description takes the remaining width. Installable function descriptions are also slimmed to their first sentence worker-side (same slimming as the search corpus) — the registry ships paragraph-length descriptions that dominated the card and cost ~150 tokens of noise per response; the full contract arrives after installing anyway.

Do not expose unresolved native tool schemas. If engine::functions::info fails, hydrate retains parameters: None, and concrete_allowed_tools exposes { "type": "object" }. Exclude that descriptor from ExposeMode::Native or retain its previous schema.

Update the hot-reload summary.
The header still lists only registry_url, download_timeout_ms, registry_cache_ttl_ms, and filter_unregistered. Add inject_hint, hint_min_workers, and registry_search so the seed file documents the new hot-reload behavior.

Clarify hint deduplication across all documentation.
The hook re-sends the hint on same-step replays. The three documents currently state an absolute once-per-session guarantee.

…fo failures fetch_catalog fetched ~250 contracts as sequential single-id engine::functions::info round trips, and one failed or malformed response discarded the whole catalog. It now uses the engine's batch form (function_ids, max 32 per call) with the batches fired concurrently — fan-out bounded to ceil(ids/32) in-flight calls under the same per-call timeout — and each entry keeps its function association by id (batch entries carry function_id even for per-entry forbidden/not_found errors), so ordering never matters. catalog_from_entries is resilient: an errored, missing, or malformed entry drops only that function. The one remaining hard error is a listed-but-empty catalog (every batch failed), which keeps the previous catalog live instead of activating an empty one.

…n chat The search renderer declared no presentation metadata, so the console kept a successful DiscoverCard behind "show raw request and response" and chat only showed the generic compact card for directory::search_functions. Declare metadata.display, matching the focused result-bearing renderers in browser (screenshot), shell (agent-run, file-changes), and web. The general catch-all renderers (browser/page.js#calls, shell/page.js#shell, and iii-directory's own #directory) deliberately stay compact, so this is scoped to the search card only. Safe by construction: every non-render path in tryRender already returns null, so a pending-approval, errored, or unparseable call still falls through to the compact card. Arrived with the discovery-worker absorption (#839); shipping here since it rides the same PR.

…stem-installed ~/.agents/skills (#851) * docs(agents): wire issue-tracker, triage-label, and domain-doc guides into AGENTS.md Adds docs/agents/{issue-tracker,triage-labels,domain}.md — how agent skills reach Linear (iii team, MOT-###), the five canonical triage labels, and the CONTEXT.md/ADR reading order — and points AGENTS.md at them under a new 'Agent skills' section. * feat(iii-directory): skill create/delete and a read-only ~/.agents/skills root Skills gain full CRUD parity with prompts: directory::skills::create {id, content} writes <skills_folder>/<id>.md with a two-layer conflict check (visible-set resolution incl. the <id>/index alias, then raw dest.exists(); D114), and directory::skills::delete removes a resolved skill plus any parent directories the removal left empty, so a deleted namespace can't keep shadowing a lower-precedence root. Both fan out {op, namespace, id} on directory::skills::on-change, and deletes (skill AND prompt) now self-write-mark so the watcher stops firing a spurious op:"external" on top of the precise op. A third scan root, agents_skills_folder (default ~/.agents/skills), serves system-installed agent skills read-only: scanned shallowly (only <skill>/SKILL.md, id <skill>/index) so support payload never floods list; namespaces shadowed by the same namespace under the global/local roots; exempt from filter_unregistered by namespace NAME (dirs actually carrying a SKILL.md) so manual global-root forks stay visible; excluded from the per-worker skills::index by file provenance; refused by update/delete (D116) and reserved against create (D115). The watcher picks the root up only when it already exists — the worker never creates ~/.agents/skills. SkillFrontmatter learns name: as a title fallback (title -> name -> H1) for the agents/SKILL.md convention. Create also rejects ids the reader could never serve: filter-hidden namespaces while filter_unregistered is on, and prompts/system-prompts path segments the classifier would route away from skills (D115). The directory UI's skills tab gains the new/delete buttons (id-shaped namePattern, applied to creates only — frontmatter titles are display fields on update), skills::create renders as a trigger card, and the config form gains the new knob. The form is also brought in line with the #837 shared-UI conventions: sentence-case copy end to end, no CSS case transforms, sans panel with mono confined to path/URL inputs, and the shared Input + Chip(tone=warning) primitives replacing hand-rolled controls. Tests pin agents_skills_folder into tempdirs everywhere (the default resolves to a REAL directory on dev machines): unit cfg helpers, the BDD harness, and the e2e config. cargo test --lib 354 passing; BDD unchanged at its pre-existing baseline. * (MOT-4506) fix(iii-directory): show the function-search card inline in chat The search renderer declared no presentation metadata, so the console kept a successful DiscoverCard behind "show raw request and response" and chat only showed the generic compact card for directory::search_functions. Declare metadata.display, matching the focused result-bearing renderers in browser (screenshot), shell (agent-run, file-changes), and web. The general catch-all renderers (browser/page.js#calls, shell/page.js#shell, and iii-directory's own #directory) deliberately stay compact, so this is scoped to the search card only. Safe by construction: every non-render path in tryRender already returns null, so a pending-approval, errored, or unparseable call still falls through to the compact card. Arrived with the discovery-worker absorption (#839); shipping here since it rides the same PR. * (MOT-4506) feat(iii-directory): announce a skill's base directory so payload skills can run Live session console-1f62d4cf showed why a payload skill (impeccable: SKILL.md + scripts/ + reference/) degrades to prose-only: the console freezes only the SKILL.md body into the session addon, so the model has no way to locate scripts/context.mjs and probes .agents/skills/ relative to the project cwd, which doesn't exist. - directory::skills::get now returns `path`, the absolute on-disk file; its parent dir is the skill's base directory per the agent-skills convention. - The console appends a 'Skill base directory: <dir>' line at both freeze sites (session addon picker and /skill:<id> slash expansion) via one shared helper; body-only when the worker predates the field. * feat(harness): copy the session id from the context chip popover * (MOT-4511) feat(state)!: default the kv store to file_based persistence and flush on shutdown The in_memory default silently lost every scope (harness turn records, context snapshots, barriers, namespace claims) on each worker restart. Defaults now: store_method file_based under ./data/state (worker-cwd relative). Shutdown flushes pending dirty scopes instead of relying on the next save-loop tick, and main handles SIGTERM (workers-dev's stop signal) so that flush actually runs. Explicit in_memory pins (CI e2e) keep their behavior; tests that leaned on the volatile default now pin it explicitly. BREAKING CHANGE: a bare state worker now persists to ./data/state; pin store_method: in_memory to keep the old volatile behavior. * (MOT-4515) fix(iii-directory): keep unsaved skill/prompt drafts across tab switches The console unmounts the directory page on every tab switch, so a half-typed new skill (or an unsaved edit to an existing one) died with the component — the editor came back empty with no warning. Unsaved work now mirrors to localStorage under `${storageKey}:draft` (already per-tab and per-collection) and is restored on mount. A creating draft is self-contained; a draft over an existing entry re-fetches its on-disk baseline so dirty tracking and save() still diff against the real file. The write/clear/keep decision is a pure function in draft-storage.ts so it is testable without a DOM: notably it KEEPS storage while a baseline load is in flight, since clearing there would destroy the work just restored. Every deliberate discard (open another entry, start a create, drill out) clears immediately rather than waiting for the load to land. Storage only ever holds work that differs from disk, so a save, delete, or discard leaves nothing behind. * (MOT-4511) fix(state): make the shutdown flush actually durable Three defects in the file_based persistence path, from CodeRabbit review on #851. Each one loses exactly the write the file_based default exists to keep. - Periodic and explicit flushes both drained the whole dirty map with no mutual exclusion, so the shutdown flush could find it already empty while the save loop's write was still in flight — and process exit then cancelled that write. A shared async mutex now spans drain, persist, and requeue for both paths. - A failed write requeued its scope with a plain insert, clobbering any newer op a concurrent set/delete had queued meanwhile. A failed Delete landing on a fresh Upsert deletes live data on the next flush. Requeue is now entry().or_insert(), so newer intent always wins. - flush_dirty only logged failures, so KvStoreAdapter::flush always returned Ok and BootHandle::shutdown's warn branch was dead code. It now attempts every scope, then reports how many failed; the adapter propagates instead of discarding. Shutdown also disconnects before flushing. shutdown_async clears the SDK's running flag, which stops its receive loop dispatching further invocations, so no request accepted after the signal can mutate the store behind the flush. Requests already executing remain a race the SDK gives no way to await — closing that needs in-flight tracking, which is out of scope here. Two tests: the requeue ordering rule, and that a failed persist surfaces as an error and leaves the scope dirty (a directory planted where the index file belongs makes the write fail without touching permissions). * (MOT-4506) fix(iii-directory): correct the base-dir helper, trigger contract, and README anchor CodeRabbit review on #851. - skillBodyWithBaseDir cut the directory at the last '/' only. The worker ships Windows binaries, so path can be C:\...\SKILL.md; worse, with no separator at all lastIndexOf returned -1 and slice(0, -1) produced the whole path minus its last character, presented to the model as a directory. Now cuts on either separator and falls back to body-only when there is none. - All three on-change trigger descriptions listed only write ops, but the fs watcher also fires them with { op: "external" }; subscribers read these descriptions as the event contract. The prompts one also omitted delete, which it has fired since the prompt CRUD landed. - README linked #layout; the heading anchor is #on-disk-layout. - Long session ids could not ellipse in the harness context chip: a flex item will not shrink past its content without min-width: 0, so the id pushed the copy button out of the popover. Same pairing the sibling .harness-ui-pop-model already uses. Also documents what happens when the agents skills root is created after boot — it stays unwatched until a restart, and reads still serve it because every read re-scans disk, so only the live doorbell is missing. Re-arming the watcher for a root that may never appear is not worth the machinery.
