pagekit-claim-check

Run a skeptical claim-check pass on a PageKit first-page draft, at light/normal/hard severity. Step 07 of the PageKit method. Use after a first-page draft exists and you want to validate it before treating it as publishable. Delegates to the pagekit-claim-checker subagent.

PageKit step 07 — Claim Check

You are running the optional durability pass on a first-page draft.

Read first

./references/prompt.md
./references/framework.md — claim-check flag types, severity calibration, principle
./references/template.md
../pagekit/references/anti-slop.md — the slop pattern catalog

Inputs

runs/<run-name>/first-page-draft.md
runs/<run-name>/proof-map.md
Severity: light, normal, or hard. Ask the user if not specified; default to normal.

Procedure

Option A — delegate to the subagent (preferred)

Invoke the pagekit-claim-checker subagent (agents/pagekit-claim-checker.md). Pass:

the path to the draft
the path to the proof map
the severity

The subagent runs read-only, produces the audit, and writes:

runs/<run-name>/claim-check.md — the audit (flagged lines, types, rewrites, recurring patterns)
runs/<run-name>/first-page-draft-corrected.md — the corrected draft (only if any line was rewritten)

Option B — run inline

Use scripts/claim-check.sh <draft> <proof-map> --severity <severity> to expand the canonical prompt for paste. Save outputs to the same paths.

After the pass

Save the audit and corrected draft.
Update working-log.md with the severity used, count of flags by type, and any recurring patterns.
If the same slop pattern showed up more than once, add it to ../pagekit/references/anti-slop.md (or strengthen the existing entry) and to ../pagekit-page-argument-shape/references/template.md's drafting-constraints list. The framework absorbs what the claim-check kept catching.

Quality gate

A strong claim-check pass:

names specific lines, not general impressions
separates claim types (overclaim / vague / unsupported / outrun proof map / editorial voice / unsourced quantitative / clinical drift / ai-slop tell)
proposes replacements that are sharper and more accurate than the originals, not simply softer
ends with a recurring-patterns summary so upstream constraints can absorb them

Do not stop at claim-check. Continue:

Write runs/<name>/evaluation.md — the run's own honest read of what worked, what stayed thin, where outputs drifted generic.
Invoke pagekit-evaluator-pass to produce the adversarial second read.
Ensure runs/<name>/working-log.md has real entries per step (replace all scaffold *[Fill in]* placeholders).
Invoke pagekit-run-check — it must return tier: FULLY LOGGED or tier: PUBLISHABLE before the run is done.
