Eval Creator Ci

Eval Creator CI

Install

bashCopy code
gh skill install pskoett/pskoett-skills eval-creator-ci

For interactive sessions, use:

bashCopy code
gh skill install pskoett/pskoett-skills eval-creator

Fallback using the Agent Skills CLI:

bashCopy code
npx skills add pskoett/pskoett-skills/skills/eval-creator-ci
npx skills add pskoett/pskoett-skills/skills/eval-creator

Purpose

Runs the outer loop's regress-test step in CI. Executes all eval cases in .evals/, reports pass/fail results, and optionally blocks merges on regressions. Can also create new eval cases from promotion candidates flagged by learning-aggregator-ci.

The interactive eval-creator skill is designed for in-session use where the user creates evals and runs them with immediate feedback. This CI variant runs on schedule or per-PR and posts results as check annotations.

Context Limitation (Important)

CI agents do not have implementation context. They execute mechanical verification methods (grep checks, command checks, file checks, rule checks) defined in eval case files. They do not interpret results beyond pass/fail — nuanced judgment is left to human review of the posted report.

Prerequisites

• GitHub Actions enabled on the repository
• gh CLI authenticated with repo access
• gh-aw extension installed (gh extension install github/gh-aw, v0.40.1+)
• .evals/ directory with eval cases (created by eval-creator or eval-creator-ci)
• .evals/EVAL_INDEX.md with eval case index

CI Contract

Hard rules for headless execution:

1. Eval execution is read-only for code — eval cases read files and run check commands but do not modify source code
2. Eval case creation writes to .evals/ only — when creating new evals from promotion candidates
3. Headless — no interactive prompts, no approval gates
4. Structured output — emit results as YAML under eval_creator_ci key
5. Gate policy — can fail the check run on eval regressions (configurable)
6. Single comment — post one consolidated results comment per run

Authoring Workflow (gh-aw)

1. Copy references/workflow-example.md into .github/workflows/eval-creator-ci.md
2. Customize trigger and gate policy
3. Validate: gh aw compile (add --actionlint --zizmor for security scan)
4. Push to enable

Persistence and Chaining

• cache-memory: stores eval run history (last-run dates, result trends) across runs. Avoids re-running evals that haven't changed.
• workflow_call: in create mode, triggered by learning-aggregator-ci via call-workflow. Receives promotion candidates as workflow inputs.
• upload-artifact: persists eval results YAML for downstream consumption.

Workflow Rules

The CI agent follows these rules in order:

Mode: Run Evals (default)

1. Read .evals/EVAL_INDEX.md to get the list of all eval cases
2. For each eval case file in .evals/cases/: a. Read the eval case metadata and verification method b. Check preconditions — if not met, mark as skip c. Execute the verification method:
   • grep-check: Search target files for pattern, compare to expected (found/not_found)
   • command-check: Run the command, check exit code and/or output
   • file-check: Verify file or section exists
   • rule-check: Read target file, search for expected content d. Compare result to expected outcome e. Record pass/fail/skip
3. Update .evals/EVAL_INDEX.md with last-run date and last-result for each case
4. Emit structured YAML under key eval_creator_ci
5. Post results summary as a PR comment or check annotation
6. If gate policy is enabled and any eval fails: fail the check run

Mode: Create Evals (from promotion candidates)

1. Read the learning_aggregator_ci artifact or gap report from the most recent learning-aggregator-ci run
2. For each promotion-ready pattern with eval_candidate: true: a. Determine the appropriate verification method based on the pattern type b. Create the eval case file in .evals/cases/ with proper frontmatter c. Add the entry to .evals/EVAL_INDEX.md
3. Commit the new eval cases (if running with write permissions)
4. Report created evals in the output

Recommended Outputs

Gate Policy

Configure blocking behavior:

Default: advisory (report but don't block). Teams should escalate to strict once eval coverage stabilizes.

Trigger Configuration

Recommended: per-PR + weekly schedule

yamlCopy code
on:
  pull_request:
    types: [opened, synchronize, reopened, ready_for_review]
  schedule:
    - cron: '0 10 * * 1'  # Monday 10am UTC (after learning-aggregator-ci)
  workflow_dispatch:

Per-PR runs catch regressions before merge. Weekly runs catch drift in the harness itself. Schedule after learning-aggregator-ci so new evals from promotions are available.

Integration with Other Skills

Upstream (feeds from)

• eval-creator (interactive) — creates eval cases manually
• learning-aggregator-ci — produces promotion candidates with eval_candidate: true
• harness-updater (interactive) — flags eval candidates after promoting patterns

Downstream (feeds into)

• self-improvement / self-improvement-ci — regression failures become new error entries in .learnings/
• Human review — failure report posted for team triage
• PR merge gate — can block merge on regressions (configurable)
