search_docsread-only

Search ZeroWidth product documentation. Returns matching pages with title, slug, public URL, and a query-relevant snippet. Use this when the user asks about a ZeroWidth product (Compass, Workbench, Caliper, Prism, Ledger, Napkin, zv1), an API behavior, or a policy. No authentication required — the docs corpus is public.

get_docread-only

Fetch the full Markdown body of a specific docs page by its slug. Use this after `search_docs` when the user needs the complete content of a page. No authentication required.

list_docsread-only

Enumerate all available docs pages, optionally filtered by product (e.g. 'compass', 'legal', 'overview'). Use this to discover what slugs exist before calling `get_doc`. No authentication required.

compass_pages_listread-only

Lists pages in the active workspace's Compass compendium. Optional `type` filter narrows to one node type (WORKFLOW, PERSON, ROLE, SYSTEM, PAIN_POINT, DOCUMENT, VALUE, PRIORITY, AUDIENCE, OFFERING). Returns summaries, 50 at a time (`limit` / `offset`, `total` and `nextOffset` in the result) — fetch one with `compass_pages_get` for the full body. When you know what you're looking for, `compass_pa

compass_pages_searchread-only

Keyword search over page titles, bodies, and tags (case-insensitive substring match), paginated. The fast way to check whether a subject already has a page before creating or linking. Returns summaries with a 300-char body snippet — fetch full text with `compass_pages_get`.

compass_pages_getread-only

Fetches one Compass page by id, including its full Markdown body, header fields, and any attached Napkin sketches — view an attached sketch's actual drawing with `napkin_boards_view` (its boardId) before discussing it.

compass_pages_create

Creates a typed page in the workspace's Compass compendium. Check `compass_pages_list` first — don't create a page for a subject the map already has; link to it instead. May return `needs_confirmation` — if so, tell the user what you're proposing, wait for their approval, then re-call with the approvalId. Only record what the human has actually told you.

compass_pages_updatecan modify

Edits an existing page's title, description, body, tags, header fields, or visibility — use this to FIX what you (or an extraction) got wrong instead of creating a duplicate. Fetch the current page with `compass_pages_get` first and preserve what the human wrote; title / body / tags replace the field wholesale, while `headerFields` MERGES over the current ones (send only the keys you're changing

compass_links_create

Creates a typed, directed edge between two pages — the knowledge graph's connective tissue. Canonical directions: PERSON or ROLE owns WORKFLOW/SYSTEM/PRIORITY, PERSON or ROLE involved_in WORKFLOW, PERSON holds ROLE, WORKFLOW uses SYSTEM, SYSTEM uses SYSTEM, PAIN_POINT affects WORKFLOW/SYSTEM/PERSON/ROLE, DOCUMENT documents anything, PRIORITY contributes_to PRIORITY (a priority that ladders up to

compass_process_diagram_ensure

Returns the Napkin diagram that holds a WORKFLOW page's steps, creating it when the page has none. If the page body has a ```mermaid block, it moves into the diagram verbatim (node ids kept, so changes anchored to a step still point at it) and leaves the body. Then edit the steps with napkin_diagrams_update using the returned diagramId. One diagram per workflow holds every step anyone has describe

compass_page_links_listread-only

All typed edges touching one page, both directions, each hydrated with the other endpoint's page summary. Use this to understand a subject's neighborhood before adding to it. Current connections only, unless includeEnded — then also relationships that have ended (validTo in the past), for questions like who handled this before.

compass_interviews_create

Mints a stakeholder-interview invite: a no-account guest link where the person talks to an interviewer agent briefed by your focusPrompt, and the transcript flows back into Compass as reviewable draft pages. THE KNOWLEDGE-GAP MOVE: when caliper_flow_performance shows failures clustered on missing company facts (the judge says the flow invented a policy, missed a rule, didn't know who owns somethin

compass_interview_targetsread-only

Ranks the PEOPLE the map says know about a page (workflow, system, pain point): `owns` links first, then `involved_in`, then weaker edges. Each target carries contact email + role from their PERSON page and their latest interview (skip someone who just gave one — interview fatigue is real). Empty result = the map doesn't know an owner: ASK THE USER who runs this, create the PERSON page + owns li

compass_interview_invite

Emails the guest link for an existing interview, framed as coming from the REQUESTING USER (their name signs it; replies go to them). Author `message` in their voice — short, human, says why THEIR knowledge matters and that it takes ~15 minutes, no account needed. The approval card shows the exact subject + message before anything sends. Limit: the invite plus ONE reminder; a third ask is the us

compass_gaps_listread-only

Lists the workspace's open questions — the gap registry: what the map doesn't know yet. Defaults to OPEN gaps. This is where you keep your head — check it before asking the user something you may already have flagged, and compose interview briefs from a subject's open questions.

compass_gaps_create

Records something you don't yet know — the gap registry is your working memory, so use it liberally while mapping or interviewing. Give one clear question, WHY it matters (what answering it unblocks), and how you'd resolve it (ask the user / interview a specific person / connect a source). No approval needed — noting your own uncertainty isn't acting on the user's behalf. Attach it to a subjec

compass_gaps_resolvecan modify

Closes a gap once you've learned the answer (ANSWERED, with the resolution) or decided it doesn't matter (DISMISSED). Keep the registry honest — resolve gaps as their answers land (from an interview, a doc, or the user) so it always reflects what's still unknown. Gaps you raised close without a card; a question a person wrote needs their approval.

compass_opportunities_listread-only

The workspace's changes — fixes, chores, new steps, experiments. Each carries `statusName` (the workspace's own word for where it is) and `statusCategory` (TRIAGE undecided, BACKLOG not started, ACTIVE in progress, DONE, CANCELED dropped), plus the older lane key in `status`. `experiment: true` marks a change measured against the Ledger: `ledgerEntryId` null means no expectation registered; `led

compass_opportunities_propose

File an AI-PROPOSED opportunity into the workspace's review queue — the scouting verb (the opportunity-scout routine's main move). Unlike compass_opportunities_create this needs NO approval: the proposal itself is the human gate — it lands in the Compass Inbox and the cockpit's Needs-you for accept/dismiss. Check compass_opportunities_list first so you never duplicate an idea. Anchor to a work

compass_opportunities_create

Record a change — a fix, a chore, a new step, or an experiment worth trying. Anchor it to a workflow page when one fits (compass_pages_list); leave unanchored otherwise. It lands in the board's first status unless you name another (compass_statuses_list). Set `experiment` only when the user wants it measured against the Ledger. May return `needs_confirmation` — summarize and wait for approval.

compass_opportunities_register_expectation

The honesty mechanism: write what the experiment is expected to change BEFORE evidence exists. Creates a Ledger decision entry and links it to the opportunity — never backfill an expectation to match an outcome. Bind a metric (ledger_metrics_list) + comparator + target when the expectation is measurable; readings then land on the entry as evidence automatically. One expectation per opportunity â

compass_opportunities_mark_implemented

The measurement window's boundary: when the user says the experiment's change actually shipped / went live / rolled out, record the landing date. Readings before it are baseline; after it, evidence of effect. Recorded once — it cannot move afterward, so confirm the date. Attaches to the linked Ledger entry as evidence. May return `needs_confirmation`.

compass_map_viewread-only

Renders the workspace's visual map to an image and returns it so you can SEE it the way the user does: an isometric drawing where every page is a structure whose shape is its type — people are figures, audiences are crowds, workflows are gears lying on the ground, systems are database drums, offerings are price tags, pain points are warning signs, documents are standing sheets of paper, values a

compass_pages_deletecan modify

Moves a page to the trash (soft delete — its connections and anchored opportunities go with it, and compass_pages_restore brings the whole set back). Use this to REMOVE a page you or an extraction created wrongly, or one the user says no longer belongs on the map; to fix a wrong title or body, use compass_pages_update instead. Page ids come from compass_pages_list / compass_pages_search. May ret

compass_pages_restore

Puts a trashed page back on the map, together with exactly the connections and opportunities its delete took. Use when the user wants a deleted page back (the pageId from the earlier compass_pages_delete, or from the Compass trash). Fails with not_found when the page is already live or never existed. May return `needs_confirmation`.

compass_links_updatecan modify

Edits an existing edge between two pages: its `kind` (how the two relate), its `note`, and/or when it was true (`validFrom` / `validTo`). Use kind to CORRECT a connection typed wrongly — 'Dana doesn't own billing, she's involved in it'. Use validTo to END one that used to be true — 'Dana handed approvals to Sam in March' ends Dana's edge in March (then create Sam's from March); the old edge st

compass_links_deletecan modify

Deletes one edge from the graph (the pages stay). Use only when a connection was never true — the system isn't used by that workflow, it was recorded by mistake. When a relationship WAS true and has stopped (the person left the team, moved roles), end it with compass_links_update `validTo` instead, so the history stays. Link ids come from compass_page_links_list. Re-creating the same edge later

compass_opportunities_updatecan modify

Corrects an opportunity's content: label, description, priority, what done means, the 1–5 value / feasibility / risk scores, the owner (a PERSON page), notes, tags, workflow anchor, external link, visibility. Fields you omit are untouched; the lane is NOT here — move it with compass_opportunities_set_status. Opportunity ids come from compass_opportunities_list. May return `needs_confirmation`

compass_opportunities_deletecan modify

Removes an opportunity from the pipeline (soft delete). For an AI proposal the user doesn't want, this is the dismiss verb; for a captured experiment that was a duplicate or a mistake, the remove verb. To conclude a real experiment without evidence, prefer compass_opportunities_set_status REJECTED — that keeps the record. Ids come from compass_opportunities_list. May return `needs_confirmation`.

compass_opportunities_acceptcan modify

The review verb for the Inbox: promotes an AI-PROPOSED opportunity (from compass_opportunities_propose or the opportunity scout) into the workspace's own pipeline. compass_opportunities_set_status does NOT do this — a proposal stays in the Inbox until accepted. Optional `status` decides its lane in the same step (BACKLOG to park it, EXPERIMENTING to start it); omitted, it lands in NEW. Fails wit

compass_interviews_listread-only

Every stakeholder interview in the workspace, newest first: who was invited, status (INVITED / IN_PROGRESS / COMPLETED), focus, message count, whether the transcript was already reviewed (documentPageId set), and the invite URL while the link is still live. Check this before inviting someone again — interview fatigue is real — and to answer 'who have we already asked?'. Read one in full with c

compass_interviews_getread-only

One interview in full — metadata plus the transcript of what the guest actually said. Read this before summarizing an interview or drafting pages from it: the transcript is the source you work from, and your compass skill has the rules for typing and splitting what's in it. Ids come from compass_interviews_list or compass_inbox_list.

compass_interviews_revokecan modify

Kills an interview's invite link — the guest's next visit sees that the link is no longer active. Use when an invite went to the wrong person, the user changed their mind, or the link leaked. Idempotent. Ids come from compass_interviews_list. May return `needs_confirmation`.

compass_inbox_listread-only

The Compass Inbox in one read: finished interviews awaiting review (transcript in, not yet turned into pages), AI-proposed opportunities awaiting accept / dismiss, and the caller's pending approval cards for Compass writes. THE place to answer 'what needs me?' for the map. Also `fillIn`: what the map is missing to say who's responsible for what (priorities with no owner, business units with no lea

compass_gaps_updatecan modify

Edits an open question's wording, rationale, or suggested resolution — for sharpening a vague question or fixing one you phrased badly. Closing a gap is compass_gaps_resolve, not this. Gap ids come from compass_gaps_list. May return `needs_confirmation`.

compass_statuses_listread-only

The statuses this workspace's changes move through, in board order — the names people use. Each sits in a group: Undecided (TRIAGE), Not started (BACKLOG), In progress (ACTIVE), Done (DONE), Dropped (CANCELED). Groups are stable across workspaces; names aren't, so use the names when talking to people and the groups when reasoning about progress. Move a change with compass_opportunities_set_statu

compass_opportunities_set_statuscan modify

Move a change to one of the workspace's statuses, by name (compass_statuses_list has them — e.g. "In review"). The old lane keys (NEW / QUALIFYING / BACKLOG / EXPERIMENTING / SETTLED / REJECTED) still work and land on that lane's default status. Only changes marked as experiments follow the Ledger: when an experiment enters an In progress status with no registered expectation, offer compass_oppo

compass_workflow_stepsread-only

Every step in a WORKFLOW page's steps diagram, in diagram order, with its phase, whether it is itself a workflow (subWorkflowPageId), and who the map says owns, does, approves, is consulted on, or doesn't do it, and `uses`: the systems or documents it's done in. `unknown: true` means nothing that counts says who does the step or what it's done in — those are the questions worth asking in an inte

compass_step_claims_listread-only

Every claim about a WORKFLOW's steps, oldest first: the step (nodeId; null = the workflow as a whole), the role or person (subject), the relation, who says so (sourceKind + sourceLabel), when it was true (validFrom/validTo), and origin — AI_PROPOSED claims are waiting for a person to review. Claims that disagree coexist; each keeps its source.

compass_step_claims_propose

Propose claims about who does what in a WORKFLOW, and what each step is done in, from what someone said. Each claim names a step (nodeId from compass_workflow_steps), a page (subjectPageId: a ROLE or PERSON, or an AUDIENCE when a customer or partner does the step; for uses a SYSTEM or DOCUMENT; for impacts a PRIORITY; for holds_to a VALUE), and a relation: owns (accountable for it), does (does the

compass_workflow_rollupread-only

Per run and per month: hands-on minutes, waiting minutes, labor cost (hands-on time priced through each role's hourly rate), and hard costs, each as a low–high range, with every step's share and its gates (approvals, handoffs, re-keying, rework). A step that is itself a workflow uses that workflow's roll-up unless it has its own estimate. `coverage` says how many steps are timed — always say h

compass_workflow_learningread-only

Newest first: steps added to or dropped from the diagram (and by whom), and claims about who does what or what a step takes — said, corrected (with what they replaced), withdrawn, or accepted from a proposal — each with its source. This is when we LEARNED things; when they were true is each claim's validFrom/validTo. Use it to brief someone on what changed in the picture, or to see what an int

compass_step_measures_propose

Propose estimates from what someone said, as ranges — people know "20 minutes to an hour", not "37 minutes"; when they give one number, use it for both ends. Each item is either a `measure` or a `gate` on a step (nodeId from compass_workflow_steps): - measure.metric `working`: hands-on minutes per run (low/high). - measure.metric `waiting`: minutes the work sits idle before or inside the step â€

compass_scenario_changesread-only

Changes whose effects reach a WORKFLOW's steps — or any nested workflow's — plus changes anchored to it with no effects yet, each with what it does per step. Pass their ids to compass_workflow_rollup's changeIds to project the workflow after them.

compass_change_effects_setcan modify

Replace a change's effects: for each step it reaches (workflowPageId + nodeId from compass_workflow_steps — a sub-workflow's steps included), one of eliminate, automate (reviewMinutes: what a person still spends checking), parallelize (its wait comes off the critical path), relax_gate (keepShare: share of the wait left, default 0.25), assist (keepShare: share of hands-on time left, default 0.5),

compass_transformations_getread-only

What the workflows behind a PRIORITY could become, at five levels (Assist, Automate, Re-form, Invert, Dissolve): for each, whether it fits, is already reached, or what it needs; what changes; what it does to the priority; time freed; and the change made from it, if any. Also the recommended level, or `settled` when the work is good as it is. state 'running' means a read is under way; null means no

compass_priority_steps_find

Reads every mapped workflow against one PRIORITY (or VALUE) and proposes the steps that move it (or where the business lives the value), one marked as what holds a priority back. Proposals wait for a person to keep them on the priority's page or in the Inbox, except in workflows someone tied to it (a serves link), where they're kept at once. Steps already tied or proposed aren't proposed again, so

compass_transformations_read

Starts reading the five levels for a PRIORITY in the background (a minute or two). Needs at least one kept step that impacts the priority. A read under way is left to finish. Check back with compass_transformations_get.

compass_transformations_respond

Records what someone told you about one level of a PRIORITY's current transformations, in their words or a faithful summary: that they already do it, what rules it out, a system that isn't ready, work still done on paper, and so on. Compass works out what it means in the background: a label for the level, facts kept on the steps they're about (every later reading of those workflows sees them), and

compass_transformations_make_change

Creates a Change from one level of a priority's transformations, with its step effects and the priority it serves, and starts drafting in Workbench up to three flows for what the level says to build (`builds`, each `drafting` until ready). Only a level that fits, once per level. May return `needs_confirmation`.

compass_step_suggestions_listread-only

Your earlier read of a WORKFLOW's steps: for each suggestion, the steps it covers (nodeIds, labels), what could do them (proposal.doer: a flow and its mode, a shim, or a task), whether it does the step or helps (reach), why, and what it would take (checklist, each item met or not). state OPEN is waiting for a person; APPLIED made a change (opportunityId), and `built` is what was built for it in Wo

compass_step_suggestions_build

Builds a step suggestion the way Compass's Build button does: makes its change if it isn't one yet, then the thing in Workbench — a flow drafted from the step itself (who does it, its times, systems, write-up, attachments, interview notes) and its checklist; a shim named for the decision; or a task whose sentence is the steps. Use this, not workbench_flows_scaffold, whenever the work came from a

compass_changes_upsertcan modify

Create or update up to 100 changes in one call, each matched by `url` — the GitHub issue, Linear or Jira ticket, PR or doc it mirrors. A url already linked to a change updates that change (label, description, status, tags, experiment, workflow — omitted fields are left alone); any other url creates a change with that link. Run it again with the same urls to keep Compass in step; nothing duplic

comments_listread-only

Lists the comment threads on one workspace entity (open first, then resolved) with authors and timestamps. Read this before weighing in on contested work — the threads are where disagreement lives before it becomes a decision.

comments_create

Posts a comment on a workspace entity — a new thread, or a reply when rootId is given. Use it to leave findings where the discussion already lives (an eval result on the flow being debated, a summary on a long thread). Mention people via mentionedUserIds (from workspace member ids) to ring their notification bell; never mention someone who didn't ask to be pulled in.

comments_resolvecan modify

Sets a comment thread's resolved state (rootId = the thread's root comment id). Resolve ONLY when the human asked or the thread's question is demonstrably settled — and say what settled it in a reply first. Reopening is for new evidence.

search_workspaceread-only

Finds anything in the workspace in one call — uploaded files (searching the text inside them), folders, Workbench flows, shims, knowledge bases and tasks, Compass pages and changes, Caliper datasets, evals, rubrics, reviews, specs and sources, Ledger entries, Napkin sketches, decks, docs, sheets, diagrams and interfaces. The same search the person uses in Home. Use it FIRST whenever the user men

entity_tags_getread-only

Returns the tags on a batch of entities of one kind — the labels galleries organize by. Ids come from the kind's list/get tool or from search_workspace. Use it before entity_tags_set so you replace the full set knowingly, and to answer 'what is this filed under'. Entities the user can't see are omitted.

entity_tags_browseread-only

Without a tag: every tag in use across the workspace with how many entities carry it, most-used first — the vocabulary the team already organizes by. With a tag: everything filed under it across every tool, each with its kind, id, title, and path. Use it to reuse existing labels instead of inventing near-duplicates, and to answer 'show me everything about X' when X is a label.

entity_tags_setcan modify

Replaces the FULL tag set on one entity (an empty list clears it). Read the current tags with entity_tags_get first and pass the merged list — this is not additive. Tags are lowercase letters, numbers, spaces, and hyphens; prefer labels already in use (entity_tags_browse) so the workspace's vocabulary stays small. The id comes from the kind's list/get tool or search_workspace.
