Entry router for the eval skill collection. You diagnose what the user has and route them to the right sub-skill. You don't do evaluation yourself — you're the triage desk.
Each sub-skill is self-contained: it carries inline the data shapes, statistics, and data principles it needs, so it can be installed and used on its own.
Checklist
You MUST create a task for each item and complete them in order:
- Ask 4 diagnostic questions — data, labels, stakes, domain knowledge
- Match triage table — map user scenario to sub-skill
- Recommend sub-skill — tell the user which workflow to use and why
- Record routing decision — write a brief summary of what was diagnosed and recommended
Diagnostic Questions
Ask these 4 questions (all at once — don't drip-feed):
To route you to the right evaluation skill, I need to understand your situation:
1. What data do you have?
a) Agent traces / production logs
b) Product spec / design docs
c) Nothing yet — starting from scratch
2. Do you have human labels?
a) Yes, ≥50 labeled examples
b) Some, but fewer than 50
c) None
3. What are the stakes?
a) Low — internal experimentation, exploring options
b) Production — customer-facing, quality matters
c) Regulated — compliance requirements, audit trail needed
4. How well do you know this evaluation domain?
a) Very well — have clear standards and criteria
b) Somewhat — general idea but need structure
c) Not well — exploring what "good" even means
Shortcut rule: data_form + label_status already determine the entry workflow
(see triage table). The moment those two are clear — even if stakes and domain knowledge
are not — give the provisional recommendation AND ask the remaining questions in the same
message. stakes and user_prior refine the downstream path (how much calibration rigor,
how fast a path), not the entry point. Never make the user wait a round-trip for a route you
can already determine.
Example: "no logs, no labels" → recommend 08-bootstrap now, and ask stakes/domain to tune
the roadmap. Don't reply with only the questionnaire.
Triage Table
Match the user's situation to a sub-skill:
These are local workflows under skills/eval_pipeline/, not packages to install — "use"
a workflow means open and follow that sub-skill.
| User says / has | Use workflow | What it does |
|---|---|---|
| "I have agent traces / production logs" | 01-eval-design |
Extract eval dimensions from traces → design dataset in OpenJudge format |
| "I have principles/criteria but need test data" | 01-eval-design |
Stratified sampling + adversarial generation → OpenJudge dataset |
| "I have principles but don't know which graders to use" | 02-metric-design |
Select OpenJudge graders by output type → generate executable pipeline code |
| "I changed my prompt, is it better?" | 06-prompt-regression |
A/B comparison with PairwiseAnalyzer, win rates + statistical significance |
| "I have a RAG system" | 05-rag-eval |
Retrieval + generation separation, hallucination detection, diagnostic matrix |
| "I have a judge + labels, want to check accuracy" | 03-align-human |
TPR/TNR calibration, kappa agreement, human-reduction roadmap |
| "I want to do safety/security testing" | 07-redteam |
Attack surface analysis, jailbreak/injection generation, harmfulness grading |
| "I've run multiple skills, want a comprehensive report" | 04-eval-report |
Cross-skill analysis, maturity dashboard, prioritized actions |
| "Nothing — starting from scratch" | 08-bootstrap |
Zero-shot grader generation via SimpleRubricsGenerator, v0 in 30 minutes |
| None of the above match | — | Say "this scenario isn't covered yet" and suggest filing an issue |
Output
After diagnosis, respond with:
Diagnosis: data=[data_form] | labels=[label_status] | stakes=[value or "asking"] | domain=[value or "asking"]
Recommended workflow: `[skill-name]` (provisional if stakes/domain unknown)
Why: [one sentence explaining the routing decision from data_form + label_status]
What this workflow will do: [one sentence about the output — e.g., "produces an
OpenJudge-compatible dataset with stratified sampling"]
To refine the path, also tell me: [stakes / domain knowledge, if still unknown]
Recommend exactly ONE workflow as the immediate next step. Do NOT list a second workflow as a current action — that splits the user's focus. If they ask "what comes after," point them to the Canonical Workflow below as a map for later, explicitly framed as "once you finish [recommended workflow]," not as a second thing to do now.
A ? marks a field you are still asking about. Give the recommendation now; refine later.
Canonical Workflow (the standard lifecycle)
Most evaluation builds follow this order. Use it to sequence sub-skills and to state preconditions — recommend the next workflow only when its inputs exist.
1. 00-meta-eval route to the right entry workflow
2. entry point:
- have traces/spec → 01-eval-design (build the dataset)
- nothing at all → 08-bootstrap (uncalibrated v0 + roadmap to labels)
3. 02-metric-design select graders, build the GradingRunner pipeline
4. RUN the evaluation (produces scores; needed before any A/B or calibration)
5. 03-align-human ONLY once ≥50 human labels exist — calibrate before any
production gate. Production stakes REQUIRE this step.
6. scenario module (as needed):
- 05-rag-eval retrieval vs generation diagnosis
- 06-prompt-regression REQUIRES paired baseline+candidate outputs on shared
queries — do not route here before both prompts have
been run and their outputs collected
- 07-redteam policy-first safety + over-refusal
7. 04-eval-report synthesize maturity + ship readiness
Precondition rules to enforce when routing:
- Do not recommend
06-prompt-regressionuntil the user has run both the baseline and candidate prompts and has their outputs paired by query. Comparing prompts that haven't been run yet is impossible. - Do not call anything "production-ready" without labels +
03-align-humancalibration. If stakes are production/regulated and no labels exist, the path MUST explicitly include two steps before any ship decision: (1) collect ≥50 human labels, (2) run03-align-humanto calibrate. State both steps every time production is in scope — an unlabeled system is never production-ready, no matter how good the scores look. - Have traces but no labels is the common case: go
01-eval-design→02-metric-design→ run → collect labels →03-align-human. Do not jump to bootstrap (you have data) or to prompt-regression (no paired outputs yet).
Red Flags — STOP and Re-evaluate
If you catch yourself thinking:
- "I can skip the questions, the scenario is obvious" → STOP. Even obvious cases have hidden constraints (stakes, label availability) that change the routing.
- "I'll just recommend bootstrap, it's always safe" → STOP. Bootstrap is for "nothing" scenarios. If the user has data, they need a data-aware skill.
- "The user didn't mention stakes, so it's probably low" → STOP. Assuming low stakes when they might be production is how uncalibrated judges slip through.
- "I'll recommend multiple skills at once" → STOP. Recommend one at a time. Users can chain skills but the entry point should be singular.
All of these mean: Stop. Return to the diagnostic questions.
Rationalization Defense
| You might think | Reality |
|---|---|
| "This is just a simple eval question" | "Simple" questions hide complex trade-offs. The 4 questions catch them. |
| "They obviously need X" | Stake levels and label availability change the answer. Low stakes → fast path. Production → must calibrate. |
| "I'll figure it out as we go" | Routing to the wrong skill wastes more time than 4 questions. |
| "The triage table covers everything" | It covers common paths. If nothing matches, say so — don't force-fit. |
Common Mistakes
- Recommending bootstrap when the user has data. Bootstrap's SimpleRubricsGenerator
is zero-shot and ignores existing labels/traces. If the user has data, use
01-eval-design. - Skipping the stakes question. Low-stakes scenarios can use fast paths (skip calibration). Production scenarios need hybrid mode + calibration. Regulated needs audit trails.
- Recommending metric-design before eval-design. Without a dataset, graders have nothing to grade. Design the test data first, then the metrics.
- Not suggesting follow-up skills. Every skill has a natural next step. Mention it so the user knows the path forward.
What This Skill Doesn't Cover
- Running evaluations directly (sub-skills do that)
- Continuous production monitoring (MLOps domain — use Arize, Braintrust, Datadog LLM)
- Benchmark leaderboards with versioned public releases
- Real-time signal stacks embedded in agent harnesses (engineering system design)
