# Evals

This directory makes trigger quality and packaging quality more reproducible.

Contents:

- `trigger_cases.json`: full regression set with `family` labels
- `train/`, `dev/`, `holdout/`: split trigger suites for iterative tuning and final verification
- `blind_holdout/`: description-optimization acceptance prompts that do not participate in candidate ranking
- `adversarial/`: harder route-collision prompts for description optimization, including noisy positives and deceptive non-trigger requests
- `confusion/`: sibling-skill routing prompts used to catch route theft and false `no_route` decisions
- `semantic_config.json`: local semantic-intent concepts, exclusions, and weights
- `promotion_policy.md`: formal rules for when a route is promotable
- `baseline_description.txt`: intentionally weaker trigger description
- `improved_description.txt`: current stronger trigger description
- `../reports/description_optimization*.{json,md}`: generated route-optimization reports for the root skill
- `failure-cases.md`: current weak spots and regression targets
- `packaging_expectations.json`: required packaging behaviors for supported targets, including IR provenance, compiler contracts, and semantic parity fields
- `output/`: Output Eval Lab cases, fixtures, and schema for with-skill vs baseline assertion grading
- registry audit tests verify package metadata, compatibility, checksum, owner, license, and Skill IR provenance
- package verification tests verify generated manifests, target adapters, zip archive safety, archive checksum, and registry parity
- install simulation tests verify archive extraction, entrypoint loading, manifest/interface readability, adapter loading, and unsafe zip blocking
- upgrade check tests verify version-bump recommendations, target diff detection, compatibility regression blocking, and release-note evidence
- adoption drift tests verify metadata-only telemetry aggregation, privacy-field blocking, and exclusion of raw local telemetry logs from zip packages
- review waiver tests verify reviewer, reason, expiry, active coverage, expired records, invalid records, and Review Studio integration
- compiler tests verify Skill IR target contracts, adapter modes, generated-file mappings, unsupported targets, and markdown/json report artifacts
- `../reports/`: generated suite JSON plus the homepage-visible family summary panel source

Regression scope now includes:

- direct positives
- direct negatives
- near neighbors
- long-context positives
- mixed-intent negatives
- explicit "do not build a skill" negatives
- semantic exclusion cases such as one-off, document-only, and future-outline prompts
- paraphrase families that avoid the original wording while preserving the same trigger intent
- long-context contamination cases where build intent or no-build intent appears after unrelated setup text
- family-based reporting across workflow-to-skill, iterate-existing-skill, document-only, one-off, and future-outline cases
- holdout verification
- description optimization reports that compare baseline, current, and optimized route wording across dev, holdout, blind holdout, and adversarial holdout gates
- judge-backed blind-holdout verification that adds a rubric-based second opinion for blind prompts
- calibration summaries that surface score gaps, threshold margins, and risk bands for each acceptance gate
- family-level drift history that records which blind and adversarial families stay clean over time
- output-quality scorecards that compare without-skill and with-skill artifacts through assertion grading, including near-neighbor and file-backed governed cases
- install-simulation checks that prove generated archives can be extracted into a temporary local skill root and loaded without touching the active global skills directory
- upgrade-readiness checks that compare registry package baselines, recommend semver bumps, and block breaking changes without an adequate declared version
- local-first adoption drift checks that turn accepted, edited, missed, rejected, script-error, and review-overdue metadata into next iteration candidates without storing raw prompts or outputs
- reviewer-waiver checks that keep warning acceptance explicit, expiring, and separate from non-waivable blockers
- compiler checks that turn Skill IR into reviewable target contracts before packaging embeds those contracts into adapters
