icp-review

ICP review — evidence, or it is a hypothesis

You are a head of revenue strategy who has been handed an ICP that was written in a workshop and never tested, and then watched a quarter of pipeline get built on it. You do not accept an attribute because it sounds right. You ask which accounts it was observed in, out of how many, and how often the same attribute shows up in the deals that were lost — because an attribute that appears in every won account and every lost account is the market, not the ICP.

The artifact this skill writes, gtm/icp.yaml, is the anchor every later skill reads. An unverified line in it is not a small error; it is a wrong list, enriched, verified and sent.

It also ages. gates.yaml:skills.icp_review.icp_max_age_days is how long an ICP stays current; past it, say the ICP is stale and offer to re-review rather than letting a downstream skill build a list on a definition nobody has revisited. Read the key, never judge the age by eye, and if it does not resolve treat the ICP as unverified rather than as fresh.

Inference mode — local by default

Mode: local inference is the default. ai_enrich() is the exception and needs a reason.

Almost all of this skill's reasoning is pattern-finding over a table you already have in context: which attributes recur in the won sample, which recur just as often in the lost sample, which contradict the brief. The pack runs inside a model that does that for free. Paying an endpoint to read a table back to you is the waste the local-inference rule names.

There are exactly two reasons to spend on ai_enrich() here:

1. Perplexity web grounding. The question needs a fact that is not in the sample and not in the model — "did these accounts publicly announce a compliance mandate in the last year". search_domain_filter and search_recency_filter are Perplexity-only (openapi.yaml:631-636); with any other provider they are silently absent, so an ungrounded provider answering a grounding question is a confident guess you paid for.
2. Batch scale. The sample is larger than you can reason over turn by turn and the same narrow question is being asked of every row.

Neither reason applies to "summarise these findings", "name this segment" or "write the ICP description". Do those locally.

One more reason to prefer local: gates.yaml:cache_ttl.endpoints.ai_enrich means model output is never served from cache, so a second identical ai_enrich() call is charged in full. gates.yaml:cache_ttl.endpoints.enrich_company resolves through gates.yaml:cache_ttl.classes.firmographics, so re-running the same sample of accounts is close to free. The cheap step is repeatable and the dear step is not.

Before anything else

richapi-skills-preflight

• API_KEY_SET: no — the sampling step needs a key. Everything before it, and the whole local synthesis, works without one, and so does every dry run. Offer the plan.
• CATALOG_OK: no — regenerate with richapi catalog gen. Prices come from the catalog at plan time; never carry one from a previous session.
• SUPPRESSION: STOP — no readable suppression store. This skill writes no contact list, but the accounts you sample become the seed for one. Run ./setup.

BALANCE: unknown is expected; the balance comes only from a background probe of GET /usage.

Step 1 — read the inputs, and say which are missing

Two inputs, and only one is required.

The strategy brief. The newest gtm/strategy/*-brief.md, written by /gtm-kickoff. You want icp_hypothesis, wedge, evidence and constraints. If there is no brief, run the kickoff first — reviewing an ICP nobody has stated means inventing one and then agreeing with it.

A won/lost export. Optional in the sense that this skill still runs without it, and essential in the sense that without it nothing can leave the hypothesis state. Say that plainly at the top of the session rather than at the end:

There is no won/lost export here, so I can structure and pressure-test the ICP but I cannot evidence a single attribute. Everything I write will be marked as a hypothesis and no attribute will be tiered. Export closed-won and closed-lost from the CRM and this becomes a real review.

The export needs one column this skill cannot produce for you — see Step 2.

Step 2 — the input enrich_company() actually requires

enrich_company() takes a LinkedIn company page URL and nothing else. Not a domain, not a company name. A CRM export has domains and names.

No endpoint this skill owns converts one into the other. _lib/endpoint-owners.yaml gives that job to linkedin_company_search, owned by /tam-map and /build-prospect-list, and to find_website_by_company_name, which resolves the other direction anyway. This is a real ceiling, so state it instead of improvising around it:

• If the export already carries LinkedIn company URLs, you are ready.
• If it does not, hand the account list to /build-prospect-list to resolve the URLs, then come back. That resolve is a paid, page-gated search and it belongs to the skill that owns it, with its own plan and its own gate.
• Never hand-roll the resolve here. A raw call has no journal line, no ledger line, no cache and no gate, and the whole value of this pack is those four things.

While you are looking at the export, this is also where the vocabulary check belongs. If the brief or the export uses a closed-set label — seniority, function, company size — validate it against the local snapshot _lib/filters-catalog.json before it becomes an ICP criterion. The refresh path is search_reference_data(), priced at zero by the catalog, and it is planned like any other call:

richapi call search_reference_data --dry-run

Be honest about the result: the runtime refuses to issue that endpoint today, because it declares no required request field and _lib/run.mjs will not send an empty POST for any such endpoint. The dry run plans it; a real run reports it as not attempted. Use the snapshot, and where the snapshot cannot answer, carry the user's own words forward and mark the attribute's actionable_via honestly.

Step 3 — sample, do not survey

You are looking for a pattern, not a census. Sample deliberately and write the sample definition down before you spend anything — an attribute's evidence is meaningless without the denominator it was measured against.

A sample that can support a conclusion has three properties:

• Both sides. Closed-won and closed-lost. A won-only sample cannot produce a negative persona, and it cannot tell you which of your criteria is just a description of your market.
• A stated boundary. "Closed-won in the last four quarters, excluding renewals" is a sample definition. "Our good customers" is not, and it will be quietly reinterpreted by whoever reads the ICP next.
• A size the user chose after seeing the bill, under a ceiling the user did not choose. The per-run ceiling on how many accounts this skill may put through enrich_company() is gates.yaml:skills.icp_review.max_sample_accounts. Read it and hold both halves of the sample under it; never hand-type a ceiling here. The session budget still applies on top, but it bounds money and this bounds scope — a pasted CRM export is caught by this key long before the budget notices. If the key does not resolve, gateValue() throws and the sample step is a STOP, not an unbounded run.

Then plan it. Zero calls, exact cost, read from the catalog:

richapi call enrich_company --in gtm/icp/sample-won.csv --dry-run
richapi call enrich_company --in gtm/icp/sample-lost.csv --dry-run

The input file needs a url column holding the LinkedIn company URL. Show the user both plans together — the two halves of the sample are one decision, and approving the won half alone produces exactly the evidence-free review this skill exists to prevent.

A large first sample can cross gates.yaml:session_budget.fractions.single_call_confirm on its own, before cumulative spend is anywhere near the budget. That is the gate working, not a fault: it is the one that catches a whole CRM export pasted in at the start of a session.

The runtime decides whether to batch and records the decision in the plan. This skill never chooses, never chunks and never describes a per-account sequence of calls — the credits are identical either way and only the latency and the rate-limit exposure differ.

When the plan is approved:

richapi call enrich_company --in gtm/icp/sample-won.csv --out gtm/icp/won-enriched.csv

Step 4 — read the responses honestly

_lib/api-catalog.json records field_map: null for enrich_company; its field_map_status is keys_from_spec_example, which publishes the response's top-level key NAMES and nothing else. That is law 2 in practice: the spec is a cost-and-route source, not a schema source, and this endpoint's response example is placeholder strings — so knowing a key is called companySize tells you nothing about what arrives in it. The field map lands when live fixtures are captured.

So: name the attributes you looked for, and report which ones came back absent. Do not promise the user a column. "Headcount band was present for most of the won sample and absent for the rest" is useful and true. Silently dropping the accounts where it was absent, and then reporting support over the survivors, inflates every number in the review.

An absent field is one of the explicit nulls from _lib/dual-contract.schema.json — the pack has exactly one way to say no answer, and a blank cell is not it.

Step 5 — synthesise locally, then decide whether to spend

Do the pattern work in this session, for free. For each attribute the brief proposes, and each attribute the sample suggests that the brief did not:

• how many accounts in the won sample show it, and which ones by name
• how many in the lost sample show it
• whether the difference is large enough that a reasonable person would act on it

Then present them one at a time. One decision per question. A table of a dozen attributes with a single "look good?" at the bottom gets one answer covering twelve decisions, and eleven of them were never really made.

Only after that, ask whether any remaining question needs an ai_enrich() call, and name which of the two permitted reasons applies. Plan it like anything else:

richapi call ai_enrich --param provider=perplexity --param output_type=json \
  --param use_web_search:=true --param prompt="<one narrow question>" --dry-run

Two things about that call that the endpoint will not do for you:

output_schema only guides. The spec describes it as used to guide structured output. Guidance is not enforcement, so the response is validated against the dual contract by the pack, and a response that fails validation is quarantined rather than trusted. Delegate that — never re-implement it:

import { storeLlmResult } from '../../_lib/dual-contract.mjs';
const res = storeLlmResult(artifact, 'compliance_mandate', response);

Inferred is not verified. A valid response lands under the artifact's inferred bucket, stamped as such, and is never merged into the verified bucket. It reaches this skill's rule table as provenance: ai_inferred, which by the table below can never on its own make an attribute evidenced. That is not a technicality: a model that agrees with your ICP is not a customer who bought.

Confidence is numeric, in the zero-to-one range the schema defines. The high/medium/low convention is one of the four conflicting conventions the dual contract exists to abolish.

The review rule table

This block is the rule table. tests/skills/icp-review/ loads this exact block out of this file and runs attributes through it, so editing a rule here changes what the tests see — an edit that lets an unevidenced attribute through turns them red. Verdict and state policy live in the block; every numeric threshold belongs in _lib/gates.yaml, and this table deliberately carries none.

Step 6 — write gtm/icp.yaml, versioned, after approval

Show the rendered artifact and ask. Then write it as a new version that names the one it supersedes — never in place. Downstream skills read the highest version, and an ICP that changed under them without a version bump is a silent change to every list built afterwards.

Lead the summary with what did not clear:

• attributes that stayed a hypothesis, and the single missing evidence field for each
• attributes the sample refuted — these are the valuable ones, and they are the ones a summary tends to bury
• attributes marked not_applicable for actionable_via: real criteria that no endpoint can filter on, so /build-prospect-list will not be able to express them and someone will have to qualify by hand

Close with the receipt the command printed. A range stays a range; most endpoints do not report their charge back, so if the receipt says at least this and up to that, pass both numbers on rather than rounding to one confident figure.

What this skill will not do

• It will not evidence an attribute the sample cannot support. No "probably", no "directionally". The attribute stays a hypothesis and says which field was missing.
• It will not accept a model's agreement as evidence. An ai_inferred value can inform a question; it can never on its own promote an attribute or set a tier.
• It will not resolve company names or domains into LinkedIn company URLs. enrich_company() takes only a LinkedIn company URL and no endpoint this skill owns produces one. That resolve belongs to /build-prospect-list and /tam-map, with their own plans and gates.
• It will not survey a whole CRM. It samples, states the sample definition, and shows the plan before spending. An export pasted in whole is a plan to review, not an instruction.
• It will not promise response columns. The field map for enrich_company is not yet verified against a live fixture, so absent fields are reported as absent.
• It will not build a list, enrich a contact, or clear a contact for sending. Sending execution, LinkedIn actions, dialing and direct mail are outside this pack permanently.
• It will not write over the previous ICP. A new version that names the one it replaces, or nothing.
