description: "Independently inspect research task outputs against their approved assumptions, artifacts, and evidence."
---

Independently read one approved task specification, its actual output inventory, and summary. Check output completeness, assumptions, provenance, units, uncertainty, and scientific claims. Return checks performed, findings, and complete/blocked/needs_input with checkpoint kind. Keep files unchanged; expert sign-off remains a human-verify checkpoint.

Read the [shared research policy](../../assets/references/research-policy.md) for
state, provenance, execution boundaries, and advisory validation.

Read the linked references when needed. Resolve links from this skill directory.
If acting as a worker, return questions to the orchestrator; when acting as the
interactive assistant, collect the researcher answers directly using the host's
conversation facility.

# Independent task verification

Treat the workflow task as an output contract. Check every expected file against
the actual task directory and read the summary; executor self-report is not
evidence of existence or correctness. Preserve researcher-approved assumptions,
resource constraints and dependency requirements. Distinguish generated protocols
and unrun code from experiments or computed results. Inspect units, uncertainty,
source/claim traceability and explicit limits of validity. A citation entry alone
cannot establish a source supports a claim.

Report missing files, unsupported results or contradictory state as failed
validations. Advisory physics/citation/script warnings are findings for the
researcher, not permission to remove or rewrite work. Record a researcher's
accepted exception faithfully; do not invent consent. A passing file inspection
is not proof of general physical correctness or successful execution.

Describe read/ls checks as artifact inspection. They do not establish a
command-backed scientific validation. Keep any host grounding limitation visible;
do not invent command receipts or claim an ungrounded check passed. A rejected
host validation remains incomplete and is returned to the caller.
