Requirement Consistency Analysis Skill: Compare Terms, States, and Rules Across Artifacts

A product can fail before code is written when one document calls a state “paid,” another calls it “captured,” and a third treats both as terminal.

Why this Skill is needed

The Requirement Consistency Analysis Skill compares artifacts using stable keys while preserving source and version boundaries. It distinguishes aligned, inconsistent, and conflict relations from assessed, missing, stale, and unassessed evidence states.

What the Skill does

Similar words are not automatically synonyms; the comparison must establish that the artifacts refer to the same object and scope.

Use this Skill when PRDs, stories, API contracts, prototypes, technical notes, or acceptance criteria describe the same flow with different terms, identifiers, formats, states, rules, or behavior.

A good comparison gives each RC finding a source pair, comparison key, relation, evidence status, scope or version, impact, owner, action, and validation method.

Use it when multiple artifacts should describe one actor, field, state transition, or outcome before implementation or integration testing.

What it does not do

The Requirement Consistency Analysis Skill can organize material, evidence, and next actions for Comparison key. It does not replace:

  • Confirmation of rules, scope, and risk by the accountable domain owner.
  • A real environment, account, dataset, log, or run record; static analysis does not become runtime evidence by itself.
  • Authorization for release, compliance, production actions, or residual-risk acceptance.
  • A Human decision when supplied sources conflict.

What it checks

The value of this Skill is not another keyword list. It connects each focus area to an observable input, a judgment, and a way to close the loop. Start with a small matrix based on the source Skill’s output contract:

FocusQuestion before analysisHandoff output
Comparison keyThe field, state, rule, or behavior being comparedStable identifier
RelationAligned, inconsistent, or conflictSeparate from evidence status
Evidence stateAssessed, missing, stale, or unassessedSource and version
ActionOwner question, close condition, and validationNo silent merge

If a row has only a conventional expectation and no source or validation method, keep it open instead of turning it into a pass.

Audit inputs before you start

Before analyzing Comparison key, classify the input into six evidence states. A gap is not automatically a failure, but it must not disappear inside the conclusion.

StateMeaningHow this Skill should handle it
knownDirectly supported by the supplied materialKeep the source, version, and time with the judgment
missingNeeded for this pass but not suppliedName the smallest evidence action and limit the conclusion
conflictingSources disagreeShow both sources and route the conflict to an owner
stalePresent but outside the relevant version or time windowMark freshness; old evidence is not current proof
out_of_scopeRelated but excluded from this passKeep the boundary explicit
assumptionsTemporarily adopted to continue analysisState how and when the assumption will be checked

Keep the input version, scope, environment, evidence locations, and accountable owner together. Without a run record, deliver analysis, design, or a validation plan—not an execution pass.

From problem to structured Finding

Connect the source, scope, evidence state, analysis, owner, action, close condition, and validation before writing the conclusion. The case below keeps this Skill’s identifier and domain context.

Keep the decision layers separate

For Comparison key, do not compress four different kinds of language into “recommended to pass”:

LayerHow to write itApplication here
FactWhat the supplied material directly showsCite the source, version, input, or run record for the focus
Evidence-backed InferenceWhat several facts support togetherShow the inference chain and retain uncertainty
RecommendationThe smallest next actionName the evidence, review, execution, or regression path
Human DecisionWhat an accountable person must decideLeave scope, risk acceptance, resources, and release meaning to the owner

A complete case

This case follows Input, Analysis, Finding, Decision, and Validation. When material is incomplete, keep missing, conflicting, or assumptions visible instead of turning them into a pass.

Input

MaterialWhat to provideWhat to do when it is missing
Artifact setPRD, API contract, prototype, acceptance criteria, and technical noteState which artifact is missing
Comparison scopeFlow, actor, field, state, platform, tenant, version, and effective timeDo not compare across unknown boundaries
Stable keysField, transition, business rule, identifier, or observable outcomeCreate a key before comparing wording
EvidenceSource locations, decisions, implementation notes, and examplesKeep absent evidence distinct from inconsistency

Use a request like this:

Use the requirement-consistency-analysis Skill.

Task: Compare the checkout PRD, payment API contract, and acceptance criteria for address fields, payment states, and refund behavior.
Inputs: [artifact versions, source locations, platform scope, examples, implementation notes]
Scope: [web checkout, card payments, release R25.1]
Constraints: [do not invent state meanings or merge conflicts]

Produce RC-## findings with source pair, stable key, relation, evidence status, impact, owner, open question, close condition, and validation method. Route explicit mutually exclusive rules to conflict detection by Skill name only.

Analysis

Use the input, matrix, and evidence state to form the judgment before writing the Finding; keep missing material as a gap.

Finding

Focused example: Compare payment states without treating names as synonyms

The PRD says an order is paid after authorization, the API returns authorized, and acceptance criteria expect captured before confirmation. The Skill should preserve all sources, compare the state transition and timing, and classify the relation only after scope and implementation meaning are checked. It should not choose the most familiar label as canonical.

The result shows relationships among supplied artifacts. It cannot prove runtime state behavior, and static agreement does not replace an API or integration test.

Example finding: turn one problem into a handoff

The field example below shows the recording pattern; it is not an execution result.

If the supplied material cannot prove that Comparison key meets its contract, write the finding like this. It does not invent the missing rule or turn missing evidence into a failure.

FieldExample wording
Source and scopeRecord the requirement, version, environment, and the concrete object for Comparison key
FindingThe condition or result for Comparison key is not yet traceable to evidence
Evidence statemissing / assumptions; use conflicting when sources disagree
Impact and priorityName the affected user, journey, or delivery decision without inflating severity
Owner and Human decisionAsk the product, engineering, security, or test owner to confirm the rule and trade-off
Action and close conditionAdd the smallest missing evidence; close only when source, judgment, and owner can be reviewed
ValidationName one repeatable check, query, or run and retain the raw artifact

The point is to let the next person walk from the finding back to the source and run an action that can change the decision.

Decision

The accountable owner confirms the decision question and risk trade-off; the Skill does not make that choice.

Validation

Before closing the finding, run the stated validation and retain the raw artifact. Without an execution record, the status remains unverified.

How a Finding enters the next stage

Handoff output

Output fieldWhy it existsExample status
Comparison keyThe field, state, rule, or behavior being comparedStable identifier
RelationAligned, inconsistent, or conflictSeparate from evidence status
Evidence stateAssessed, missing, stale, or unassessedSource and version
ActionOwner question, close condition, and validationNo silent merge

Every conclusion should point to a source, evidence state, and next action. If evidence is missing, use pending, blocked, unassessed, or NOT_SCORED instead of filling the gap with confidence.

Next-stage route

At minimum, hand off the source, evidence state, owner, close condition, and validation action; the next-stage conclusion remains bounded by the evidence state.

How to prepare better input

Provide all artifacts with versions and locations, comparison scope, stable keys, examples, and known decisions. When only one source exists, mark missing comparison evidence instead of calling it consistent.

A useful handoff includes input versions, scope, time window, evidence index, assumptions, Human decision boundary, and the smallest validation action.

Working with other Skills

Common traps

  1. Treating similar labels as the same object without checking state, timing, or actor.
  2. Calling a missing second artifact consistent because no difference was found.
  3. Downgrading a true conflict into an inconsistency to make the report cleaner.

FAQ

What is the difference between relation and evidence status?

Relation describes how two statements relate. Evidence status describes whether the comparison is sufficiently supported, fresh, or missing.

Should the Skill create a canonical glossary?

It can propose a question or candidate mapping, but approved terminology and state meaning remain a Human or product decision.

The Skill is most useful when attached to one real project artifact and kept with its source evidence. Start narrow, validate the uncertain part, and expand only when evidence supports it.
