knowledge_demand_list

List the demand index. Operation knowledge.demand.list · Platform level · permission tax_knowledge:read · risk tier read · since M7

The demand index: per customer-location jurisdiction, the demand across every organization in one mode (spec §42.2, README §7). For each jurisdiction with a signal: waitlist entries by stage (waiting, pending, notified, left) with the waiting entries' estimated value; checkouts paused there in the window (blockedCheckouts, by reason); net sales in the window where the knowledge base is only at coverage L0 (l0Sales, where quotes are out of scope, with an EUR equivalent for sorting); and subscribers' legal entities established there. With each, how many organizations and brands it comes from, never which: the index holds counts and sums only, no customer data. coverage is the jurisdiction's level, target and tier, to compare demand with what the knowledge base supports.

Sort by waitlist, blocked_checkouts, l0_sales, entities or jurisdiction; the window is this calendar month and the ones before it (months, default 12). Platform staff only.

knowledge_jurisdictions_list

List tax jurisdictions and their coverage. Operation knowledge.jurisdictions.list · Platform level · permission tax_knowledge:read · risk tier read · since M3

Lists the jurisdictions of the Jurisdiction Knowledge Base: the coverage map. Each one has its coverage level (L0 known, L1 tax, L2 registration, L3 filing, L4 connector) and target, its priority tier (1 = launch), the status of its own record (meta), and counts of its records by status (records), with their open questions and the earliest nextReviewBy.

Filter by tier, coverage level or the jurisdiction record's status. Sorted by ID; paginate with limit (1–100, default 100) and starting_after (the previous next_cursor). Records at researched or cross_checked aren't reviewed yet: live mode uses only reviewed or verified records (spec §7.2).

knowledge_regimes_list

List tax regimes. Operation knowledge.regimes.list · Platform level · permission tax_knowledge:read · risk tier read · since M3

Lists the regimes of the Jurisdiction Knowledge Base as loaded. A regime is a set of rules for one jurisdiction and seller situation, for example HR_DOMESTIC, EU_OSS_UNION or US_SALES_TAX:TX: who it applies to, the registration threshold (money as integer micros), grace rules, evidence and place-of-supply rules, and how to register. Each has its record meta (status, confidence, open questions, sources).

Filter by jurisdictionId (regimes that cover it or live in its folder) or status (one or several). Sorted by ID; paginate with limit (1–100, default 50) and starting_after (the previous next_cursor).

knowledge_research_get

Get the research schedule. Operation knowledge.research.get · Platform level · permission tax_knowledge:read · risk tier read · since M3

Returns the research plan of the Jurisdiction Knowledge Base and what is due today (UTC): the research waves of waves.yaml with their status (merged once the wave's pull request is merged), dependency state and report; the recurring waves (rate sweeps, quarterly Tier 1 re-research, overdue reviews) with their current occurrence and whether it is due; the jurisdictions with records past nextReviewBy (overdue); and the wave reports. Each due item has a prompt to paste into a Claude Code session opened in the Ownrecord repository: research runs there, never in the platform (spec §42.6).

Waves and reports come from the research data compiled with the app (artifact); overdue records and wave scopes from the knowledge loaded in the database (loaded). Demand-based promotions need the demand index and aren't evaluated yet. Platform staff only.

Annotations: readOnlyHint: true · destructiveHint: false · idempotentHint: true · openWorldHint: false

Arguments

This tool takes no arguments.

  • Read-only: changes nothing; idempotency_key is ignored.

Errors

  • permission_denied: You aren't platform staff (organizations read the knowledge itself, not the research schedule).

knowledge_research_reports_get

Get a research wave report. Operation knowledge.research_reports.get · Platform level · permission tax_knowledge:read · risk tier read · since M3

Returns one research wave report (data/tax/knowledge/reports/<id>.md) as markdown: the facts a wave added or changed per jurisdiction, open questions, disputes, unsupported rules and runs that couldn't finish (spec §42.6 step 4). id is the file name without .md, as knowledge.research.get lists them.

knowledge_review_items_create

Open a knowledge review item. Operation knowledge.review_items.create · Platform level · permission tax_knowledge:admin · risk tier write · since M3

Adds an item to the knowledge review queue: something in the Jurisdiction Knowledge Base to look at, such as a record ready for promotion (status_promotion), a changed source (source_changed), a research diff (research_diff) or an open question or dispute (open_question). Name what it is about in recordRef (a record such as HR/rates.yaml#*:standard@2013-01-01 or HR/regimes/HR_DOMESTIC.yaml, or a source such as HR:S3) and optionally assign it to platform staff. detectedBy defaults to user; items from the rate monitor or a research wave raise a KNOWLEDGE_REVIEW_OPEN alert.

Tracking only: nothing here changes tax rules. The change is a commit in the knowledge base, reviewed as a pull request; resolve the item with that commit or pull request. Platform tax admins only.

dry_runbooleannotrue: check permissions and rules and compute the result, then roll everything back. Nothing is saved. (default false)
  • Idempotency: the result returns the idempotency_key used, yours or one the server generated. Retry with it: a call with the same key and arguments never acts twice (keys are kept for 24 hours).
  • Dry run: supported. dry_run: true checks permissions and rules and computes the result, then rolls everything back.

knowledge_review_items_update

Update a knowledge review item. Operation knowledge.review_items.update · Platform level · permission tax_knowledge:admin · risk tier write · since M3

Changes an item of the knowledge review queue:

  • Assign an open item to platform staff (assignee: a user ID), or unassign it (assignee: null).
  • Resolve an open item (status: resolved) with the commit (resolvedByCommit) or pull request (prUrl) that changed the knowledge base, and an optional note.
  • Dismiss an open item that needs no change (status: dismissed) with a note saying why.
  • Reopen a resolved or dismissed item (status: open).

Tracking only: resolving changes no tax rule; the commit does, once it is merged and loaded. Platform tax admins only.

Arguments

ArgumentTypeRequiredDescription
idID (kri_…)yes–
statusone of open, resolved, dismissedno–
assigneeID (usr_…) or nullno–
resolvedByCommitstringno–
prUrlstringno(at most 2000 characters)
notestringno(1–2000 characters)
idempotency_keystringnoA unique string for this change. Retrying with the same key and arguments never acts twice. When left out, the server generates one and returns it in the result's idempotency_key. (1–255 characters)
dry_runbooleannotrue: check permissions and rules and compute the result, then roll everything back. Nothing is saved. (default false)
  • Idempotency: the result returns the idempotency_key used, yours or one the server generated. Retry with it: a call with the same key and arguments never acts twice (keys are kept for 24 hours).
  • Dry run: supported. dry_run: true checks permissions and rules and computes the result, then rolls everything back.

knowledge_state_get

Get the loaded tax knowledge. Operation knowledge.state.get · Platform level · permission tax_knowledge:read · risk tier read · since M3

Returns which version of the Jurisdiction Knowledge Base the platform uses: the git commit it was compiled from, when it was loaded (loadedAt, loadedBy) and what that load changed (lastLoad), with counts of the current records per collection and per status. Every change to tax rules is a reviewed commit; the knowledge_sync job loads it after the next deploy. Before anything is loaded, loaded is false.

Tax knowledge is shared by every organization and read-only (spec §41.2).

Annotations: readOnlyHint: true · destructiveHint: false · idempotentHint: true · openWorldHint: false

Arguments

This tool takes no arguments.

  • Read-only: changes nothing; idempotency_key is ignored.
