| name | goal-evaluator |
| description | Evaluate whether a goal, feature, project, or investment is worth pursuing — before committing resources to it. Covers ROI, opportunity cost, timing, reversibility, strategic fit, bias correction, and exit criteria. Use this skill when deciding whether to start something new, when a goal feels compelling but unclear, when you need to justify a commitment, or when you suspect the real cost or value hasn't been honestly assessed. Trigger phrases: "is this worth doing", "should we pursue this", "evaluate this goal", "is the ROI good enough", "is the scope too small to bother", "help us decide if this is worth it", "we're thinking of doing X — is it a good idea", "is this the right thing to focus on", "assess this opportunity", "should we invest in this". Outputs one of five verdicts: PURSUE / REFINE / DEFER / DESCOPE / DROP. Use before project-compass (direction) and working-standards (execution).

Goal Evaluator Skill
Answers one question before resources are committed:
Is this goal worth pursuing — now, at this scope, by this team?
Standard ROI misses too much: vague goals that can't be evaluated, optimism
bias that inflates value and deflates cost, opportunity cost of what won't
get done, and timing that determines whether even a good goal succeeds.
This skill covers all of it.
Five Possible Verdicts
Every evaluation ends with one of these:
PURSUE ── Conditions are met. Start now with confidence.
REFINE ── The idea has merit but the goal is too vague to evaluate or execute.
Clarify first, then re-evaluate.
DEFER ── Worth doing, but not now. A specific trigger or condition must
be met first. Set a review date.
DESCOPE ── The full scope isn't justified, but a smaller version is.
Define the smaller version and pursue that.
DROP ── The goal does not justify the investment at this time.
Explain why and what to consider instead.
Evaluation Workflow — 7 Phases
Phase 1: Clarity Test
Before evaluating anything, confirm the goal is clear enough to evaluate.
A goal that cannot be made specific cannot be honestly assessed.
Vagueness is not a sign of ambition — it is a sign that the thinking
isn't done yet.
Ask:
□ Can you state in one sentence what "success" looks like?
□ Is there a measurable condition that marks the goal as complete?
□ Do all stakeholders agree on what the goal means?
□ Can you distinguish "done" from "better than before"?
If any answer is NO → output REFINE immediately.
Do not proceed through the remaining phases on a vague goal.
Provide 3–5 clarification questions that, when answered, would allow
full evaluation.
See references/clarity-questions.md embedded in the value framework.
Phase 2: Value Analysis
What do you actually get if this succeeds?
Map value across four layers — goals often have value at one layer
but not others, which changes the assessment:
DIRECT VALUE — What immediately improves?
Quantify where possible: "saves X hours/week", "reduces Y by Z%"
If value is qualitative only → flag as hard to verify
INDIRECT VALUE — What else becomes possible because of this?
Does success unlock other goals?
Does it create capability that compounds over time?
Does it change what the team/product can do?
STRATEGIC VALUE — Does this advance the direction we want to go?
Even if direct value is modest, is this a stepping stone?
Does it build skills, data, or position that matters later?
RISK OF NOT DOING IT — What happens if we skip this entirely?
Is this defensive (prevents loss) or offensive (creates gain)?
What's the realistic cost of inaction?
Value ceiling:
What is the maximum realistic value if everything goes well?
This is not the optimistic case — it is the best realistic case.
See references/value-cost-framework.md for value estimation methods.
Phase 3: Cost Analysis
What does this actually cost — fully loaded?
Most cost estimates miss at least one of these:
RESOURCE COST — Direct investment required
Time: how many person-hours/weeks/months?
Money: direct spend, tooling, infrastructure?
People: who specifically, and what else won't they do?
OPPORTUNITY COST — What will NOT happen because of this?
List the top 2–3 things that get deprioritized or dropped.
What is their combined value?
Is this goal more valuable than those combined?
RISK COST — The expected cost of failure
Risk cost = probability of failure × cost of failing
Include: wasted resources + morale cost + delay of alternatives
REVERSAL COST — How expensive is being wrong?
If this turns out to be the wrong goal after 4 weeks:
What has been spent that can't be recovered?
What has been changed that's hard to undo?
Low reversal cost → lower bar to proceed
High reversal cost → higher bar required before committing
Total realistic cost = Resource + Opportunity + Risk + Reversal
Most evaluations use only Resource cost and underestimate by 2–3×.
Phase 4: Probability Assessment
What is the realistic chance this succeeds?
This is the most systematically underestimated input in any ROI calculation.
STEP 1 — Base rate check
What percentage of similar goals at similar organizations succeed?
Use this as the starting point, not your team's optimism.
General base rates (adjust for context):
Well-defined technical task, known solution path: 70–85%
Feature with clear requirements, known domain: 50–70%
Novel capability, uncertain solution: 30–50%
Strategic initiative, depends on adoption: 20–40%
Exploratory goal, unclear success criteria: 10–30%
STEP 2 — Adjust for team-specific factors
Factors that raise probability:
✦ Team has done this exact type of work before
✦ Strong early evidence (prototype, user validation)
✦ All required skills exist in the team
✦ Low dependency on external decisions
Factors that lower probability:
✦ Goal requires skills the team doesn't have
✦ Depends on 3+ external factors outside team control
✦ Similar goals have been attempted and abandoned before
✦ No clear owner
STEP 3 — Pre-mortem
Imagine it is 6 months from now and this goal failed.
Write the most likely reason it failed. Then ask:
"Is that reason present right now?"
If YES → the base probability should be reduced by 15–30%.
See references/bias-correction-guide.md for full pre-mortem protocol.
Phase 5: Expected Value Calculation
The math that makes the trade-off explicit.
EXPECTED VALUE (EV) = (Probability of Success × Value if Successful)
− Total Cost
− (Probability of Failure × Reversal Cost)
Example:
Value if successful: 80 units
Probability: 55%
Total cost: 30 units
Reversal cost: 10 units
Probability of failure: 45%
EV = (0.55 × 80) − 30 − (0.45 × 10)
= 44 − 30 − 4.5
= 9.5 units
Positive EV → pursue (if opportunity cost is also favorable)
Negative EV → drop or descope
Near-zero EV → compare against alternatives before deciding
Opportunity cost adjustment:
Subtract the EV of the best alternative that won't be pursued.
If (EV of this goal) < (EV of best alternative) → even positive EV
goals can be the wrong choice.
Adjusted EV = EV of this goal − EV of best forgone alternative
Adjusted EV > 0 → this goal beats the alternative
Adjusted EV < 0 → the alternative is the better use of resources
Phase 6: Bias Correction
Challenge the estimates before accepting them.
Human judgment on goals is systematically biased. Apply these corrections:
OPTIMISM BIAS CHECK — Value inflation
"If someone else proposed this goal and estimated this value,
would you accept that estimate?"
Common inflation patterns:
- Assuming best-case adoption
- Ignoring maintenance cost after launch
- Double-counting value across layers
- Assuming the problem is as bad as the most vocal complainers suggest
Correction: Identify the one assumption that, if wrong,
would most reduce the value estimate. How likely is it wrong?
PLANNING FALLACY CHECK — Cost deflation
"When was the last time a goal like this came in at or under estimate?"
If rarely → apply a multiplier to resource cost:
Simple, well-understood work: ×1.2
Moderate complexity: ×1.5
Novel or cross-team work: ×2.0
SUNK COST CHECK — Past investment distorting judgment
"If we had not started anything on this yet, would we still pursue it?"
If NO → sunk cost is inflating the case for continuing.
Past investment is not a reason to continue future investment.
MOTIVATED REASONING CHECK — Wanting the answer
"Who proposed this goal, and do they benefit from it being approved?"
"Have we genuinely considered the DROP verdict, or are we looking
for reasons to PURSUE?"
If the evaluation feels like it's building a case rather than
finding the truth → run the pre-mortem again from a skeptical angle.
See references/bias-correction-guide.md for full correction protocols.
Phase 7: Strategic Fit + Timing + Exit Criteria
Three final checks before the verdict.
Strategic Fit:
□ Does pursuing this move us toward the direction we've committed to?
□ Does this build capability we'll use again, or is it one-off?
□ If this succeeds, does it make the next goal easier or harder?
□ Is this the best use of our resources toward our stated direction?
If strategic fit is LOW but EV is HIGH → consider DESCOPE
(capture the value without investing in an off-direction capability)
Timing:
□ Why now rather than in 3 months?
If there's no good answer → consider DEFER
□ Is there a forcing function (deadline, external event, window closing)?
YES + genuine → valid reason to act now
NO → timing is arbitrary; is that ok?
□ What changes in 3 months that makes this better or worse?
Better conditions coming → DEFER
Window closing → act now or lose the opportunity
No change → timing is flexible; proceed on merit
□ What must be true before this is the right time?
If conditions aren't met → DEFER with specific trigger defined
Exit Criteria:
Every goal needs a defined stopping condition — not just success,
but also the conditions under which we stop before success.
Define before starting:
Success looks like: <measurable outcome>
Stop/abandon if: <conditions that trigger stopping>
Review checkpoint: <date or milestone to reassess>
Minimum viable signal: <earliest evidence that validates or invalidates>
A goal without exit criteria runs until resources run out.
