The Fit Scorer

Score an account list against ICP criteria and return a ranked priority table with outreach rationale per account.

What drives scoring accuracy. Methodology and input quality drive scoring accuracy far more than the weighting does, and the same failure modes that wreck sales forecasts wreck ICP scores: subjective inputs, silent gaps that default rather than flagging, and criteria defined by what is easy to observe rather than what predicts. Two consequences for this skill:

  • Mark which signals are observed versus asserted. A tier built mostly on asserted or inferred signals is a hypothesis, and should be labelled one rather than presented alongside evidence-backed tiers as though they were equivalent.
  • A score nobody has checked against outcomes is decoration. Where the user has history, ask whether previously High-tier accounts actually converted better than Medium. If they did not, the criteria are wrong and re-weighting them will not help. If no history exists, say the model is uncalibrated rather than implying the tiers are predictive.

Before you write

Run the input list below before you write anything. If one of those inputs is missing, ask for it and stop. Do not return a draft with a warning on it. The user copies the draft and leaves the warning behind, so a caveat protects you and not them. Ask at most THREE questions. Hard cap. Before anything becomes a question, get it yourself: read .agents/product-context.md, fetch the site or page they named, compute it from numbers they already gave, or look up the platform default. Whatever is left after that, and everything past the third question, becomes a stated assumption the user corrects in one word rather than a question that stops the work. Number them, and say what you will assume if one goes unanswered. Check .agents/product-context.md first so you never ask for something already recorded there.

Write it the way you would say it. Read references/house-rules.md and apply it to everything you return: answer first, ordinary words, short sentences, top three rather than all fourteen, no em dashes. Its nine-question check, quality plus safety, runs on your output in addition to this skill's own.

Constraints

Never score, tier, route, segment, or exclude a person on a special category. The rule and its edge cases are in references/agent-security.md. Read it and follow it.

Expressed incumbent pain is a strong signal, and it is missing from most scoring models. A decision-maker publicly naming a tool they are unhappy with, on a podcast, in a post, in a community thread, on a review site, is stronger evidence of a live buying window than any job posting, because it is dissatisfaction stated by the person who can act on it. Weight it as strong, alongside a funding event or a leadership hire.

And define "confirmed contact" before applying the tier cap. An unverified row in an enrichment export is asserted, not confirmed. Confirmed means the person appears in a source that the company controls or that you checked directly, a team page, their own post, a live profile the user viewed. Where only an export row exists, say asserted and treat the cap as unresolved rather than satisfied, because a tier gate resting on an undefined word is not a gate.

When an input is missing, choose a response - never fill the hole silently. The rule and its edge cases are in references/missing-input-protocol.md. Read it and follow it.

Context

  1. If .agents/product-context.md does not exist, build it yourself. Do not tell the user to go and run another skill first. Read their website and public sources for positioning, ICP, the offer and tiers, brand voice, proof points and competitors. Ask only for what research genuinely cannot establish, inside your three-question budget. Then write what you learned to .agents/product-context.md so the next skill does not repeat the work, and say in one line that you created it and what you inferred rather than observed. The parts this skill needs most are the ICP criteria (including the disqualifier list) and the product one-liner.
  2. Read .agents/product-context.md for the ICP criteria (including the disqualifier list) and the product one-liner. Any input below that these already cover is usually recorded there: pull it and confirm with the user rather than asking them to restate it.

How to run

Ask the user for:

  1. Their ICP criteria (company size, ARR range, target industries, required roles on the team, key signals they look for)
  2. Their product description in one sentence
  3. The account list: one account per line with any enriched data available (company name, headcount, industry, signals like funding, hires, stack)

If the user provides a partial list (e.g. just company names), work with what is available and note what signals are missing.

Output format

Return a markdown table with these columns:

| Company | Tier | Rationale | Outreach Angle |

  • Tier: High / Medium / Low
  • Rationale: one sentence explaining why this account fits or does not fit the ICP right now, referencing the specific signal that drove the tier
  • Outreach Angle: only for High-tier accounts. The single strongest angle to lead with in the first email or call

After the table, add a short summary:

  • How many High / Medium / Low accounts
  • The top 3 accounts to contact this week and why. If fewer than 3 accounts reached High, list only the High ones and say how many there were: do not pad the list with Medium accounts to reach three, and do not promote a Medium account to fill the slot. If zero accounts reached High, say that outright and name what signal or contact confirmation the list would need to produce one.
  • Any accounts that should be removed from the pipeline entirely (no fit), with a one-line reason

Scoring logic

Weight signals in this order (adjust if user specifies different priorities):

  1. Leadership hire (new CRO, VP Sales, VP Marketing, Head of Growth hired in last 90 days): strong signal
  2. Funding event (last 180 days): strong signal
  3. Hiring for SDR, RevOps, lifecycle, or growth ops roles: medium signal
  4. Stack sprawl (3+ tools across CRM + email + analytics): medium signal
  5. Active LinkedIn posting from a contact at the account: low signal
  6. Headcount growth 20%+ in last 6 months: medium signal

An account needs a real, named contact who holds the required role from the user's ICP criteria (the "required roles on the team" gathered in step 1 of How to run) confirmed as present at the account. Company-level fit alone does not satisfy this. Use this as a hard gate: if no such contact is confirmed, cap the tier at Low regardless of how strong the other signals are, and say so plainly in the Rationale column (e.g., "capped at Low: no confirmed contact in the required role").

Quality check before returning

Scope of these checks. Two rules before you run them, because testing found both failures in most skills in this pack:

  • A check you cannot answer from the inputs you asked for is conditional, not skippable. If it needs data the Inputs section never collects, run it only when the user happened to supply that data. Otherwise say the check did not run and name the input it needed. Never skip it silently, and never invent the data to make it pass. Inventing is the likelier failure and the worse one.
  • Every figure stated in this skill's own instructions is a pack benchmark, not the user's number. Label it inline as such wherever it reaches the output, or replace it with [NEED: source] if it is doing real work in a decision and no source exists. House rules 4b and 4c have the full version.

Before returning the output, verify:

  • Is expressed incumbent pain scored as a strong signal where present, rather than falling through the model as no-signal?

  • Is every required-role contact marked confirmed or asserted, with an unverified export row treated as asserted and the tier cap stated as unresolved?

  • Does every row's Tier trace back to the specific signal named in the Rationale column, not a generic "good fit" statement?

  • Is the Outreach Angle filled in only for High-tier accounts, and left blank for Medium/Low?

  • Where the account list was partial, does the output note which signals were missing rather than silently scoring around the gap?

  • Does the summary's "top 3 accounts to contact this week" actually match the three highest-scoring rows in the table?

If any check fails, correct it before returning the output.

Part of the SDR pack

This is one of 9 SDR skills. They chain - the order you run them in changes what you get, and running one in isolation usually means re-answering setup another skill already captured. 8 best Claude Code skills for SDRs walks the whole pack in the order the skills actually chain.

Questions about The Fit Scorer

Everything you need before installing, plus how the skill actually behaves once Claude picks it up.

Scores an account list that already exists against ICP criteria and returns a priority tier of High, Medium, or Low with a one-sentence outreach rationale per account, plus what was inferred rather than observed. It's a Claude Agent Skill - a folder with a SKILL.md file and reference material - so Claude loads the methodology on demand when you ask for what you need in plain language, instead of you pasting a template.
