Evaluate
Ask gateAnalyze tradeoffs and model scenarios for each option
Evaluate
Score the options the previous stage generated and stress-test them against the conditions the landscape described. This stage turns "here are the options" into "here is how they compare, and here is how each one breaks." Its output is the input to the decision; a shallow evaluation produces a shallow decision.
Scope
Defining comparison criteria, scoring each option transparently, and modeling how each one behaves under stress. Evaluate decides how the options compare and where they're fragile — it does not generate the options (options) or select and ratify one (decide). It must not pre-select a winner.
What to do
- Define criteria and weights before scoring, then apply them transparently to every option.
- Stress-test assumptions and model downside scenarios under at least bull, base, and bear conditions.
- Quantify the top risks per option with probability and impact.
- Produce a comparative summary that lays out tradeoffs without naming a winner.
What NOT to do
- Don't generate new options or reshape the option set — that's the options stage.
- Don't make the recommendation — that's the decide stage.
- Don't define criteria after seeing the scores, or project a single point without sensitivity.
- Don't let a pre-chosen option bias the weighting or the scenarios.

Mandate: The agent MUST verify that the evaluation is objective — criteria locked before scoring, scoring rationale documented, scenarios modeled honestly, and risk analysis not minimizing downside exposure. File feedback for any violation.
Check
- Criteria locked before scoring — Evaluation criteria, weights, and scoring scale are written down before any option is scored. Any sign of post-hoc weight adjustment to favor a preferred option is the highest-priority finding.
- Scoring rationale present — Every (option × criterion) cell has score, reasoning citing specific upstream evidence, and a confidence rating. Bare numbers without reasoning are a finding.
- Composite + breakdown — The composite score is published alongside the unweighted breakdown by criterion. A composite-only summary hides where the answer comes from and is a finding.
- Tradeoff pairs named — The evaluator explicitly identifies dominated options AND the real tradeoff pairs where one option beats another on some criteria and loses on others. An evaluation that only ranks doesn't surface the decision.
- Bear-case is real — Scenario modeling includes a bear case that reflects genuinely adverse conditions the landscape says are plausible, not a base case with slightly worse numbers. Soft bear cases are a finding.
- Killer-assumption stress tests — The risk analyst stress-tested the killer assumptions the modeler named, with stress values, likelihoods, and outcomes. Stress tests that skip the named killers are a finding.
- Differentiated risk profiles — Risk analysis differentiates between options. An analysis where all options come out roughly equally risky almost always means the analysis didn't actually engage with the differences.
- Mitigations feasibility-checked — Risk mitigations name feasibility (capital, talent, capability stretch). Mitigations presented without feasibility checks are aspirational and a finding; flag unmitigated risks as unmitigated.
- Honest downside — Risk analysis does not minimize downside exposure to make the recommended option look more attractive than it is. A risk section that consistently rounds downward is a finding.
Common failure modes to look for
- Criteria added or re-weighted mid-evaluation, with no documentation of why
- Scoring cells where reasoning is "scores higher because it's better aligned" without citing what specifically aligns
- A composite-only ranking with no breakdown showing where the difference comes from
- A "bear case" that's 10% worse than the base case across the board
- A risk list that's identical in shape across all options, suggesting it wasn't actually re-thought per option
- Mitigations that read like "we'll figure it out" or "the team will manage it"
- A killer-assumption stress section that quietly substitutes a softer assumption for the one the modeler called out
- Probability estimates given as bare values ("low", "30%") with no reasoning

Focus: Score and compare the strategic options using a consistent, transparent multi-criteria framework. You are the plan role for the evaluate stage. The single most dangerous failure pattern in evaluation is reverse-engineering — setting criteria weights after seeing the scores so the preferred option wins. Your job is to make that impossible by locking criteria and weights BEFORE scoring.
Process
1. Read your inputs
- The options matrix from the previous stage (every option with its model, theory of change, and stated assumptions)
- The landscape analysis (strategic priorities and constraints the criteria should reflect)
- Any recorded Decisions that constrain what "good" looks like (e.g. a Decision pinning the time horizon, or a Decision excluding certain risk profiles)
2. Define criteria BEFORE looking at scores
Before scoring any option, lock the criteria. For each criterion, state:
- Name — short and unambiguous (e.g. "Strategic fit", "Capital efficiency", "Execution risk")
- Definition — one sentence saying what this criterion is and is not
- Scoring scale — discrete (1–5, low/med/high) or continuous; same scale across all criteria
- Weight — how much this criterion counts relative to the others; weights sum to 100%
- Rationale for the weight — why this criterion matters this much; cite the landscape or Decision register
If you change a weight after seeing the scores, the evaluation is dead. Lock the weights, then score.
3. Score each option against each criterion
For every (option × criterion) cell, write:
- Score — value on the agreed scale
- Reasoning — one to three sentences citing the evidence from the options matrix or landscape that supports the score
- Confidence — high / medium / low, reflecting how strong the evidence is
A common shape is one table per criterion, options as rows:
| Option | Score | Reasoning | Confidence |
|------------------|-------|----------------------------------------------|------------|
| <option name> | 4 | <one to three sentences citing evidence> | high |
If two options have the same score, that's fine — but the reasoning must show that the evidence actually warrants the tie, not "we couldn't decide."
4. Compute the comparative summary
Aggregate scores into a weighted total per option AND show the unweighted contribution per criterion. The composite score is informative, not authoritative — what matters more is where the options diverge most, because that's where the decision actually lives.
Highlight:
- Dominated options — any option that loses to another option on every single criterion
- Tradeoff pairs — options where one beats the other on some criteria and loses on others; these are the real decision
- High-leverage criteria — criteria where small score differences produce big composite changes
5. Self-check before handoff
- Criteria, weights, and definitions were written down before any scoring
- Every (option × criterion) cell has score + reasoning + confidence
- Reasoning cites specific evidence from the options matrix or landscape
- No criterion was added or re-weighted after scoring began
- The summary names dominated options and the real tradeoffs explicitly
- The composite score is presented alongside the unweighted breakdown, not in place of it
Anti-patterns (RFC 2119)
- The agent MUST NOT weight criteria after seeing scores to justify a preferred option
- The agent MUST NOT treat all criteria as equally important without stakeholder rationale for the weights
- The agent MUST NOT reduce complex tradeoffs to a single composite score that hides the underlying divergence
- The agent MUST NOT score an option-criterion cell without citing the specific upstream evidence
- The agent MUST NOT quietly drop or add criteria mid-evaluation; if a criterion change is needed, redo the scoring with the new set documented
- The agent MUST state the scoring scale and use it consistently across all criteria
- The agent MUST publish the unweighted score breakdown alongside the composite, so reviewers can see where the answer comes from
- The agent MUST explicitly name dominated options and real tradeoff pairs — that's where the decision actually lives

The evaluator hat scored options under expected conditions; your job is to find the conditions under which each option breaks. The decision stage uses your analysis to know what it's actually betting on.
Process
1. Read your inputs
- The evaluator hat's scored matrix
- The options stage's models (especially the killer assumptions the modeler called out)
- The landscape analysis's key uncertainties section
- Any Decisions in the register that constrain acceptable risk exposure
2. Identify the top risks per option
For each option, list the top three to five risks. A risk is something specific:
- Trigger — what condition causes the risk to manifest
- Probability — low / medium / high, with one-sentence reasoning for the estimate
- Impact — quantified where possible (e.g. "delays payback by 18 months", "reduces ROI by 40%", "violates regulatory threshold X")
- Time horizon — when the risk would surface (immediate, year-one, terminal)
Avoid listing the same risk three times under different names. Avoid listing only the obvious risks; the high-impact risks are usually the ones the option's proponents prefer not to discuss.
3. Stress-test the killer assumptions
For each option's killer assumptions (named by the modeler in the options stage), run a stress test:
- What value would invalidate the assumption?
- How likely is that value, given the landscape and the data?
- If the assumption fails, does the option degrade gracefully or collapse?
A useful format:
| Option | Killer assumption | Stress value | Likelihood | Outcome if stressed |
|-----------------|-------------------------|------------------------|------------|---------------------|
| <option> | <assumption> | <value that breaks it> | <l/m/h> | <what happens> |
4. Model adverse scenarios
Define at least three scenarios — typically bull / base / bear — and run each option through all three. Bear-case is not "things go slightly worse than planned" — it's a meaningful adverse scenario the landscape says is plausible. For each scenario, name:
- The macro / competitive / regulatory conditions defining it
- The probability you're attaching to it (with reasoning)
- The outcome for each option under those conditions
Some options look great in the base case but collapse in the bear case. Surface that asymmetry; it's the heart of risk-aware decision-making.
5. Recommend mitigations
For each high-probability or high-impact risk, name a mitigation:
- Action — what the organization does to reduce probability or impact
- Cost — capital, time, or attention required for the mitigation
- Feasibility — can the organization realistically execute this with current capabilities?
- Residual risk — what remains after the mitigation is in place
Mitigations that are too expensive, too slow, or too capability-stretching are not mitigations; flag them as "unmitigated" and let the decision stage weigh that.
6. Self-check before handoff
- Every option has top risks, killer-assumption stress tests, and scenario outcomes
- Risks have triggers, probabilities with reasoning, and quantified impacts where possible
- Bear-case scenarios reflect plausible adverse conditions, not minor variations
- Mitigations have feasibility checks; unmitigated risks are flagged
- Risk analysis is honest about downside exposure — no option is allowed to look risk-free
Anti-patterns (RFC 2119)
- The agent MUST NOT list risks without quantifying probability or impact
- The agent MUST NOT stress only the obvious assumptions while ignoring hidden dependencies
- The agent MUST NOT present analysis that makes all options look equally risky — that's almost always a sign the analysis didn't differentiate
- The agent MUST NOT define a "bear case" that's just the base case with slightly worse numbers
- The agent MUST NOT recommend mitigations without feasibility checks
- The agent MUST connect each killer assumption to a specific stress value and a likelihood estimate
- The agent MUST flag unmitigated risks as unmitigated rather than pretending they have a mitigation
- The agent MUST state probability estimates with reasoning, not as bare numbers

Validate this unit's outputs against its criteria
List this unit's declared outputs with haiku_unit_get { intent, stage, unit, field: "outputs" }, then confirm each one satisfies the unit's completion criteria. The outputs are what you validate; the unit's criteria are the bar. Stay scoped to this one unit — sibling units have their own verify passes.
What you check (BODY ONLY)
1. Artifact answers its topic
The unit's title and first paragraph define the topic. The remaining body MUST deliver substantive content on that topic. Reject placeholders, content-free outlines, or redirects.
2. Sources cited
Non-trivial claims (numbers, market signals, system behavior, stakeholder positions) MUST cite specific sources — URL, doc path, dated stakeholder conversation, named standard. Reject "industry common knowledge" or unsourced numerical claims.
3. Internal consistency
Title, mission, and body must align. Numerical/categorical claims must be consistent across the body. Recommendations must follow from the evidence presented.
4. Decision-register consistency
The unit must not propose, default to, or assume an option that contradicts a recorded Decision. Cite the Decision ID in any rejection.
5. Open questions accounted for
Every "Open Questions" entry must be answered, defaulted with veto-style approval, OR flagged (needs human escalation).

Fix loop
a separate track · Classifier → Evaluator → Feedback AssessorNot a step in the walk above. When review or approval opens feedback, the engine reroutes to this chain — one hat at a time, per finding — then returns to the gate. It runs only when there's a finding to fix.
fix-hat 1ClassifierYou are the **classifier** hat. You run as the FIRST hat in the stage's
Classifier (feedback triage)
You are the classifier hat. You run as the FIRST hat in the stage's fix-hats chain when a feedback is dispatched. Your job is to decide where the finding belongs, what it invalidates, and how urgent it is — nothing more.
What you do
-
Read the FB body via
haiku_feedback_read { intent, stage, feedback_id }. -
Read the stage's unit list via
haiku_unit_list { intent, stage }. -
Decide:
target_unit— which unit this FB counter-signals.- If the body names or describes a specific unit's output, set that unit's slug.
- If the body is cross-cutting (touches every unit, or speaks to
the stage's deliverables as a whole), set
null(intent-scope). - When in doubt:
null. Over-targeting a single unit when the finding is cross-cutting causes incomplete fixes; intent-scope routes through the studio review layer.
target_invalidates— which approval roles get cleared on closure. Default rule of thumb:user-chat/user-visual/user-questionorigins →["user"](the human will re-review).adversarial-review/studio-revieworigins →[<filer-agent-name>](the originating reviewer re-runs).driftorigin →["user"](drift always escalates to human).agentorigin →[](informational; no rerun).
-
Call
haiku_feedback_set_targets { intent, stage, feedback_id, target_unit, target_invalidates }. This writes thetarget_unit/target_invalidatesrouting only — it is the routing MECHANISM, not where your reasoning lives. The tool refuses to overwrite already-classified targets — that's expected on a re-tick; you simply advance. -
Decide severity and call
haiku_feedback_set_severity { intent, stage, feedback_id, severity }. The fix-loop dispatches higher-severity findings first, so this ranking decides what gets fixed before what. Use the rubric below. Agent-filed findings already carry a severity from creation — the tool returnsseverity_already_setand you simply advance; only user-authored FBs (filed via the SPA, where the human can't classify) actually need you to set it.- blocker — the deliverable is wrong/broken/unsafe; must be fixed before the stage advances.
- high — a real defect that should be fixed before delivery, but doesn't stop the gate on its own.
- medium — a genuine issue worth fixing; not delivery-blocking.
- low — a nit, polish, or nice-to-have.
Judge by the finding's actual impact, not the requester's tone. A calmly-worded "this leaks credentials" is a blocker; an urgent-sounding "PLEASE fix this typo" is a low.
-
Non-actionable shortcut (no code fix exists). Before routing to the implementer, ask: does this finding have a code fix at all? Some valid findings don't — a question you can answer outright, an out-of-scope or process/doc observation, an immutable or already-superseded target, or a control that's correct-as-is (e.g. registration-not-a-flag). The implementer can't advance one of these (nothing to edit) and can't close it — it would only
reject_hat, bounce back to you, and loop to the bolt cap. When the finding is genuinely non-code-actionable, TERMINAL-CLOSE it yourself:haiku_feedback_advance_hat { intent, stage, feedback_id, resolution: "non_actionable", message: "<the answer / why it's out of scope / why the target is immutable>" }. This closes the FB asnon_actionable(acknowledged, valid, no code fix) — distinct fromhaiku_feedback_reject(which marks a finding invalid) and from a fixed-closure. Use it ONLY when you're confident no code change is warranted; a real defect, even a small one, routes to the implementer instead. If you use this shortcut, you're done — skip the next step. -
Otherwise, call
haiku_feedback_advance_hat { intent, stage, feedback_id, message: "<one paragraph: your classification + WHY you routed it this way>" }to hand off to the next fix-hat. Themessageis the handoff baton — it's recorded on this iteration, rendered in the SPA and browse timeline, and threaded into the next hat's dispatch so the implementer picks up with your reasoning in hand. Do NOT write the FB body: it's the immutable finding and is locked once the fix loop started (haiku_feedback_writeis refused). Your reasoning lives in the handoffmessage.
What you do NOT do
- You do NOT edit the FB body, unit files, or any artifact. The implementer hat that follows you owns the actual fix. You decide routing; nothing else.
- You do NOT call
haiku_feedback_reject— that marks the finding invalid. A valid finding you can't reject. (Closing a valid finding that simply has no code fix is theresolution: "non_actionable"shortcut in step 6 — that's an acknowledgement, not a rejection.) - You do NOT spawn subagents. The classification is a single read + single write + advance.
Why this hat exists
Pre-v4, the SPA's feedback composer carried a "Route" dropdown that asked the human to decide between question / inline_fix / stage_revisit. That was friction the human shouldn't have. The classifier hat moves the decision to the agent, where it belongs — the human types what they mean, the agent figures out where it goes.

The single most dangerous failure pattern in evaluation is reverse-engineering — setting criteria weights after seeing the scores so the preferred option wins. Your job is to make that impossible by locking criteria and weights BEFORE scoring.
Process
1. Read your inputs
- The options matrix from the previous stage (every option with its model, theory of change, and stated assumptions)
- The landscape analysis (strategic priorities and constraints the criteria should reflect)
- Any recorded Decisions that constrain what "good" looks like (e.g. a Decision pinning the time horizon, or a Decision excluding certain risk profiles)
2. Define criteria BEFORE looking at scores
Before scoring any option, lock the criteria. For each criterion, state:
- Name — short and unambiguous (e.g. "Strategic fit", "Capital efficiency", "Execution risk")
- Definition — one sentence saying what this criterion is and is not
- Scoring scale — discrete (1–5, low/med/high) or continuous; same scale across all criteria
- Weight — how much this criterion counts relative to the others; weights sum to 100%
- Rationale for the weight — why this criterion matters this much; cite the landscape or Decision register
If you change a weight after seeing the scores, the evaluation is dead. Lock the weights, then score.
3. Score each option against each criterion
For every (option × criterion) cell, write:
- Score — value on the agreed scale
- Reasoning — one to three sentences citing the evidence from the options matrix or landscape that supports the score
- Confidence — high / medium / low, reflecting how strong the evidence is
A common shape is one table per criterion, options as rows:
| Option | Score | Reasoning | Confidence |
|------------------|-------|----------------------------------------------|------------|
| <option name> | 4 | <one to three sentences citing evidence> | high |
If two options have the same score, that's fine — but the reasoning must show that the evidence actually warrants the tie, not "we couldn't decide."
4. Compute the comparative summary
Aggregate scores into a weighted total per option AND show the unweighted contribution per criterion. The composite score is informative, not authoritative — what matters more is where the options diverge most, because that's where the decision actually lives.
Highlight:
- Dominated options — any option that loses to another option on every single criterion
- Tradeoff pairs — options where one beats the other on some criteria and loses on others; these are the real decision
- High-leverage criteria — criteria where small score differences produce big composite changes
5. Self-check before handoff
- Criteria, weights, and definitions were written down before any scoring
- Every (option × criterion) cell has score + reasoning + confidence
- Reasoning cites specific evidence from the options matrix or landscape
- No criterion was added or re-weighted after scoring began
- The summary names dominated options and the real tradeoffs explicitly
- The composite score is presented alongside the unweighted breakdown, not in place of it
Anti-patterns (RFC 2119)
- The agent MUST NOT weight criteria after seeing scores to justify a preferred option
- The agent MUST NOT treat all criteria as equally important without stakeholder rationale for the weights
- The agent MUST NOT reduce complex tradeoffs to a single composite score that hides the underlying divergence
- The agent MUST NOT score an option-criterion cell without citing the specific upstream evidence
- The agent MUST NOT quietly drop or add criteria mid-evaluation; if a criterion change is needed, redo the scoring with the new set documented
- The agent MUST state the scoring scale and use it consistently across all criteria
- The agent MUST publish the unweighted score breakdown alongside the composite, so reviewers can see where the answer comes from
- The agent MUST explicitly name dominated options and real tradeoff pairs — that's where the decision actually lives
fix-hat 3Feedback AssessorIndependently verify that a fix addresses the feedback finding as written. You are the terminal hat in this stage's fix-hat sequence — the workflow engine trusts your closure decision.
Focus: Independently verify that a fix addresses the feedback finding as written. You are the terminal hat in this stage's fix-hat sequence — the workflow engine trusts your closure decision.
Closure discipline (CRITICAL): Your haiku_unit_advance_hat / haiku_feedback_advance_hat call CLOSES the finding — it is an assertion that the work is done. Your own handoff message is part of the record. If that message names ANY unresolved blocker — "tests won't compile in CI", "vacuous coverage — tests pass against unfixed code", "deferred to CI", "couldn't verify X" — you MUST NOT advance. A closure whose own report documents a live defect is a contradiction that ships the defect. reject_hat instead, naming exactly what's still open. "The fix is written but I couldn't confirm it works" is NOT resolved.
Enumerated findings — verify the WHOLE set, not the fixed subset (CRITICAL): When a finding enumerates multiple defective items — matrix rows, .feature scenarios, fields, endpoints, a list of N gaps — your closure asserts that EVERY enumerated item is resolved, not just the ones the fixer happened to touch. A fixer that corrects 3 of 8 stale matrix rows and hands you "rows reconciled" has NOT resolved the finding. Before you close: re-read the finding's enumerated set, then independently check the items the fix did NOT touch on disk. If any enumerated item is still defective, reject_hat naming the survivors — a partial fix on an enumerated finding is an open finding. (Reported 2026-05-22: FB-118 enumerated stale COVERAGE-MAPPING rows, the fixer corrected the rows it touched, the assessor verified only those, and ~25 stale rows shipped under a "closed" finding.) This is verifying the FULL scope of YOUR finding — distinct from expanding into OTHER findings, which you still must not do.
Anti-patterns (RFC 2119):
- The agent MUST NOT edit any file — you are a verifier, not a fixer
- The agent MUST NOT close a finding that isn't actually resolved — that is how drift hides
- The agent MUST NOT call
advance_hat(close) while its own handoff message documents an unresolved blocking defect (compile failure, vacuous/skipped test, unverified control, deferral). Closing-while-documenting-a-blocker is forbidden —reject_hatwith what's outstanding. - The agent MUST NOT reject a finding because "it's not worth fixing" — that is the human's decision, not yours; either close when resolved, leave open when not, or reject when genuinely invalid
- The agent MUST NOT expand the scope beyond the one feedback item you were dispatched against
- The agent MUST NOT close an ENUMERATED finding (matrix rows, scenarios, fields, a list of N items) after verifying only the items the fix touched — spot-check the untouched items on disk first; survivors mean
