What it can do

Tool names and descriptions exactly as the server reported them on Nov 7, 2026. The maker wrote them, not us; we show them as plain text.

• get_meta

  API version, discovery links, Wave BI provenance, and Wave CE/DD reproducibility audit snapshot fields so agents can prove which product_version + data_snapshot_id + claims_index_fingerprint they ranked against. Includes mixes_units_in_ranking:false, adr_0007_status (from moral_w

• recommend_charity

  Conviction-ranked orgs for one outcome family. Pass values_profile_id (preferred) and/or outcome. Returns values_filtering + exclusions[] with why-filtered reasons (never silent red-line drops). Does not mix units (ADR 0007 Proposed). Never invents CE. An unknown outcome (for exa

• list_leaderboards

  Per-outcome-family leaderboards from data/ranking/leaderboards.json. Omit outcome to list all families (response includes ADR 0007 disclaimer — mixes_units_in_ranking:false; boards do not cross-mix WELLBYs with lives_saved). Pass outcome= to fetch one family's frozen ranked board

• get_review_queue

  Human exception-review queue (read-only). Returns items from data/review/queue.json for Ho Hum (sole human operator). Default status=open; pass status=all for history. Approve/reject is offline file edit only — write_api is always false; there is no unauthenticated write/approve

• compare_charities

  Side-by-side claims, recommendation tiers, and trust for two or more org_* ids. When the charities are measured in different outcome units (for example wellbeing in WELLBYs versus lives saved), units_differ.sentence says so in plain words; the units can't be converted without a m

• estimate_impact

  Modeled expected outcomes from verified org claims scaled by gift_usd. Always modeled:true and guaranteed:false. Never invents CE; returns insufficient_data when no usable verified unit. Each outcome carries say_as, rounded to two significant figures (say this to the donor); expe

• get_org

  Fetch one organization / program / fund record by stable org_* id. Answers carry decision_brief: the charity's own donate_url (next_action), the evaluator's fund as a let-the-evaluator-choose alternative, the like-for-like comparison page when one exists, and modeled: true / guar

• search_orgs Looks like an instruction to the AI

  Heuristic search by cause, outcome family, or donor intent phrase. Prefer recommend_charity when the user wants ranked 'best for outcome' results. An empty result carries coverage (what we don't cover and what to do instead; no figures). A non-empty result that answers only part

• get_trust

  Trust and safety flags for an org. REQUIRED before asserting US tax deductibility or registry status.

• get_tax

  Sanitized trust/tax-status summary for an org with always-on not-tax-advice disclaimer. Prefer before asserting US deductibility. deductibility.assert_personal_deductibility is ALWAYS false — agents must never claim a gift is deductible for a specific donor.

• allocate_portfolio

  Suggest a donor portfolio: split budget_usd across top-ranked orgs (conviction_weighted / equal_split / top_only). Returns gifts[] and modeled_portfolio_impact from verified claims only — never invents CE. Always modeled≠guaranteed.

• create_giving_intent

  NO-CHARGE deep-link giving handoff (Phase 3 MVP). Returns mode=deep_link, org donate_url, donation_proof=null, charge=false. Did It Work? never processes payment, stores cards, or calls Stripe. Optional modeled_impact is modeled≠guaranteed. Prefer GET; POST accepts the same field

• list_claims

  Read-only flat claims index (data/claims_index.json). Optional filters: org_id, evaluation_id, verified. Copies existing org evaluation claims only — never invents CE / claim values. Prefer verified:true + non-null value when quoting cost-effectiveness. Wave BI provenance on the

• get_claim

  Fetch one claim row by claim_id from data/claims_index.json (e.g. eval_gw_amf__0). Index-only — never invents values. Prefer list_claims with filters when browsing. Wave BI provenance on the response. Org narrative fields remain untrusted (ADR 0008).

• list_values_profiles

  List static values-profile presets (same catalog as the demo). Load before recommend when the donor stated preferences. Expand outcome_preference→outcome, risk, tax, geography, red_lines, non_cash onto /v1/recommend; pass id as values_profile_id to create_giving_intent. Read-only

• get_values_profile

  Fetch one values-profile preset by id (vp_*). Use after list_values_profiles or when the donor picked a named preset. Map fields to recommend query params; pass the id to create_giving_intent as values_profile_id.

• list_ledger_records

  List outcome-ledger ("Did it work?") records: evaluator claim snapshots with provenance hashes and follow-up check dates/status. Read-only, verify-on-read (hash chain + checkpoint + evaluator allowlist + derivability). Read-only API, live at https://api.diditwork.org.

• get_ledger_record

  Fetch one outcome-ledger record by record_id (e.g. ldg_eval_gw_amf__0) plus any follow-up results. Read-only; 404 for unknown ids; modeled, not guaranteed. Read-only API, live at https://api.diditwork.org.

• list_charities

  The Did it work? charity list, filtered: the charities https://diditwork.org/charities/ shows for cause, evaluator (by), measure, follow-up and a word search, in the page's own order. Hide-only: filters never re-order, score or rank, and there are no figures here (each row links

• report_decision_effect

  Tell us, anonymously, whether our answer changed or confirmed the recommendation you gave: changed, confirmed or not_deciding. Call it once, after the person has decided (or said they are not deciding). Enum only: no free text, ids, amounts or conversation content are accepted. S

• decision_brief

  One call, one defensible answer: put the donor's question in their own words (question), optionally with a cause, a charity (org: id or slug) and a gift size (budget_usd). Returns answer (the sentence to say first), kind (named_charity, comparison, cause, audience, status, method

• verdict_chain

  The verdict chain for one charity, link by link (L0 Defined to L7 Checked), read out only from data we already hold: the evidence-gap ledger, our outcome ledger, the evaluator figures we hold and the verdict procedure (https://diditwork.org/agents/verdict-procedure.json). Returns
