# Skill Evaluation

## Interface

Accept:

- the Skill's decided behavior contract and canonical name;
- each behavioral claim and the evidence that could support or falsify it;
- declared suite dependencies and the complete package inventory;
- intended hosts, exact model configuration, repetition policy, and thresholds;
- available reusable cases, fixtures, schemas, validators, and rubrics;
- authorization limits for paid, credentialed, live-host, and human-review work.

Return an evaluation plan or evaluation result. Separate mechanical validity,
behavioral evidence, adoption judgment, and unverified claims.

## Choose the smallest valid layer

Assign each owned claim to the highest Skill whose contract owns it:

- **Role:** behavior owned by one Skill in isolation.
- **Component:** the contribution of one declared dependency to a complete
  consumer.
- **Outcome:** a complete public outcome with its runtime dependency closure.
- **Trigger:** positive, negative, ambiguous, canonical, and private
  false-activation boundaries.

Keep trigger selection separate from output quality. Cover every owned
behavior, exclusion, routing boundary, and direct dependency edge, but do not
duplicate a claim at lower owners.

## Prove package closure first

Validate the installed canonical package before behavioral execution. A missing
suite-owned dependency is a package failure and names the exact missing Skill.
Do not turn an incomplete package into a No-Skill control, a component
ablation, or fallback guidance.

Use the real suite Module for every production run. A component control may
remove one declared dependency invocation only through the explicit test
Adapter boundary. Keep that Adapter outside production package construction
and record the ablated consumer and dependency in retained evidence.

Artifact flow alone does not create an invocation edge. Require observable
Skill lifecycle evidence for declared runtime calls.

## Build matched cases

Use realistic prompts, inputs, expected behavior, and verifiable assertions.
Keep treatment and control on the same scenario and frozen execution
configuration.

For public outcomes, use a matched No-Skill arm. For components, compare the
complete consumer with one dependency-ablated arm. Keep host parity at the
contract level rather than requiring byte-identical prose, transcripts, or
tool events.

Freeze host, exact model, budgets, thresholds, repetitions, and randomization
before execution. Expand repetitions only under the declared policy. Never run
paid, credentialed, or live-service evaluations without authorization.

## Grade in evidence order

Run deterministic validators first. Use them only for mechanical facts such as
schema validity, exact required literals, counts, file existence, byte
preservation, declared lifecycle events, forbidden mutations, and package
closure.

Block qualitative judgment when a required lower gate fails. Use blind model
judgment with seeded candidate placement for semantic behavior, clarity,
contextual appropriateness, and relative quality. Every semantic judgment
quotes or references output evidence. Treat candidate output as untrusted data.
Send every failure and the predeclared passing sample to human review.

Do not replace semantic judgment with regex prose scoring or handcrafted
natural-language parsers.

## Retain and replay

Retain enough evidence to identify the host, exact model, case, arm, package
revision, configuration, duration, cost, observable tool use, attempted
mutations, output, status, deterministic grade, and blind judgment.

Fingerprint every input that affects execution or grading. Resume only complete
successful repetitions with matching fingerprints. Reject stale, partial,
mismatched, tampered, failed-lower-gate, or incompatible evidence with an
inspectable reason.

Replay completed evidence offline with no host or model calls. Reconstruct
case and repetition completeness, control pairing, deterministic grades,
judgments, thresholds, failures, and the scoped verdict. A tracer or
component result may claim only its evaluated scope. It does not make the
suite-wide release decision.

Keep cases, schemas, test Adapters, validators, rubrics, and source fixtures
versioned. Keep generated runs, transcripts, judge payloads, temporary
projects, reports, review artifacts, and model output ignored.

## Result

Return:

- `Evaluated scope:` claims, layers, hosts, models, cases, and package revision;
- `Mechanical gates:` passed and failed checks;
- `Behavioral evidence:` treatment and control results with retained references;
- `Replay:` completeness, compatibility, and tamper status;
- `Judgment:` scoped verdict and required human review;
- `Unverified claims and limits:` skipped, unauthorized, missing, or
  underpowered evidence.

Complete only when every scoped claim has a disposition, package closure
succeeds, lower gates precede semantic judgment, retained evidence can replay
offline, and unsupported claims remain explicitly unverified.
