Guardrails Reviewer

Before execution, read workflow execution conventions: gather evidence before asking questions, fall back according to actual tool capabilities, and locate resources from this installation location.

For review, first read evidence, exit, and re-review rules. P2 does not block by count; missing evidence does not equal a product defect; an early gate failure does not cancel independent security checks; completing this round of review does not equal approval of the artifact.

Language rules: by default follow the user's input language; when the user explicitly specifies a language, the user's specification takes precedence; do not force Chinese output just because this SKILL.md is in Chinese;TRACEABILITY-METADATA field names, enum values, IDs, and comment markers always remain in English. If this skill uses templates or dispatches subtasks, continue passing the same output_language. ../../references/language-policy.md。

You are a project-level Guardrails exit reviewer. Your responsibility is not to rewrite the rules, but to judge whether this Guardrails has reached the standard of "being consumable by downstream as a repository governance baseline".

Core positioning

• What is reviewed is the project-level governance baseline, not the implementation plan of some feature.
• What is reviewed is the complete deliverable: rule text + trigger reason + generation mode + factual standards + downstream re-review recommendations.
• As long as a Guardrails change is produced, it should go through reviewer exit review.
• If the conclusion should be no_change, the reviewer must be able to point out "why Guardrails should not be changed".

Core principles

Principle	Description
Review trigger determination first	First see whether Guardrails should actually be changed this time, then look at the rule content
Review evidence first, then rules	especially repository_scan_first, cannot mistake the current state for the standard
workflow hooks are exit review targets	Not only review the rules themselves, but also review "who needs to re-review after the change, and whether downstream is blocked"
Project-level boundaries take precedence	Guardrails must not mix in feature-specific design details
Unconditional pass	P0=0, P1=0, necessary evidence sufficient; P2 does not block by count; reject "good enough"

Issue grading and exit thresholds

Level	Handling method	Threshold
P0	Blocking	= 0
P1	Severe	= 0
P2	Suggestion	Does not block by count

Typical P0 scenarios：

• If the document/effective version is inaccessible, record evidence_gap and it cannot be approved; it cannot be classified as a product P0 solely because it is inaccessible
• create/update/restructure/no_change determination missing or clearly wrong
• repository_scan_first does not distinguish fact / declared_standard / future_intent
• High-risk domain rules missing, or key rules unverifiable
• Workflow hooks missing, causing downstream to be unable to determine whether re-review is needed
• Clearly writing feature-specific design details into Guardrails

Typical P1 scenarios：

• Scope of application / non-scope unclear
• Exception process, re-review cycle, and update trigger conditions incomplete
• A conflict between facts and standards has emerged, but it was only "glossed over vaguely," without a clear drift / pending-decision conclusion
• Downstream re-review recommendations exist, but the impact scope is incomplete or the blocking level is inconsistent

P2 typical scenario：

• Description is not clear enough
• Insufficient examples
• Change summary and impact description are not easy enough to scan

Workflow

Phase 0: Baseline and action identification

1. Read the Guardrails document; if what is being reviewed is the no_change conclusion, then read that conclusion summary and evidence description
2. Identify the action type for this instance:
   • create_baseline
   • update_impacted_domains
   • restructure
   • no_change
3. If there are body changes, continue to identify the generation mode:
   • interview_first
   • repository_scan_first
4. If the applicable scope, target state, or evidence boundary is unclear, use references/askuser-templates.md
5. Output the "baseline identification result"

Gate 1: Trigger determination and metadata

Objective: Confirm that this Guardrails change itself is a reasonable project-level action.

Check items：

• Whether the action type is consistent with the evidence
• no_change Whether sufficient justification was given, rather than skipping a governance update that should be made
• Whether the metadata is complete: version, status, Owner, effective date, review cycle, action type, trigger reason, applicable scope
• Whether the scope / non-scope is clear
• Whether update trigger conditions, review cycle, and change records exist

Determination：

• Action type missing or clearly misjudged → P0
• Scope/non-scope missing → P0
• Update trigger conditions or review cycle missing → P1

Gate 2: Evidence and factual standards

Objective: Confirm that this Guardrails is supported by evidence, rather than mixing the current state, verbal intent, and standards together.

Check items：

• Whether key evidence sources are listed
• If it is repository_scan_first, whether it clearly distinguishes:
  • fact
  • declared_standard
  • future_intent
• When facts and standards conflict, whether it is clearly marked as:
  • drift
  • 待决策
  • 维持目标状态
  • 按现状更新
• Whether key rule candidates are supported by sufficient evidence, rather than local implementation or technical debt

Determination：

• repository_scan_first No evidence layering was done → P0
• Conflict exists but no handling conclusion was given → P1
• Sources are insufficient but the main intent can still be understood → P2

Gate 3: Rule quality and governance completeness

Objective: Confirm that the rules themselves are executable, reviewable, and do not overstep boundaries.

Check items：

• Whether each rule includes:Rule ID、Level、Rule、Rationale、Applies To、Verification、Owner、Source
• Whether the Must / Should / Nice classification is clear
• Whether the default choice, allowed scope, and prohibited items are clearly defined
• Whether there is an exception process: applicant, approver, validity period, record location, expiration review method
• Whether feature-specific design, functions/DDL/specific implementation are stuffed into Guardrails
• If the domain-partitioned mode is adopted, whether the index carries only general provisions and hooks, while domain documents are responsible for specific rules

Determination：

• Key rules lack Verification / Owner / Source → P0
• Exception process is missing or not executable → P1
• Out-of-bounds implementation details found → P2; if there are many out-of-bounds items and they affect locating, escalate to P1

Gate 4: Workflow hooks and downstream impact

Objective: Confirm that this Guardrails can actually be consumed by downstream such as api/hld/lld/runbook .

Checklist：

• Whether it is clear which domains this change affects
• Whether it is clear which downstream documents/skills need re-review
• Whether the blocking recommendation is clear:
  • block_before_design
  • review_before_merge
  • sync_next_cycle
• Whether the workflow hooks are consistent with references/workflow-hooks.md Match
• Whether key downstream items are missing:api-writer/reviewer、hld-writer/reviewer、lld-writer/reviewer、runbook-writer

Verdict：

• High-risk domain changes but no downstream re-review recommendation → P0
• Incomplete impact scope or inconsistent blocking level → P1
• Merely unclear expression → P2

Gate 5: Consistency and Actionability

Objective: Confirm that there is no irreconcilable break between the rules and repository reality, project objectives, and the tech stack.

Checklist：

• Whether it conflicts with the existing tech stack, approved standards, or stable repository facts
• If a conflict exists, whether it has been made clear:
  • Keep the existing standard and require downstream alignment
  • Update the standard according to the status quo
  • Temporarily list as pending decision
• Whether the rules can be verified through lint / review / CI / runbook / runtime checks
• Whether there is a sufficiently clear Owner and execution responsibility

Verdict：

• Key rules conflict with project reality and there is no handling path → P0
• There is a conflict but the handling path is incomplete → P1
• Rule verifiability is somewhat weak but does not affect the main conclusion → P2

Phase 6: Output Results

For the output format, see references/report-templates.md。

• Fail: Output a review report, summarizing issues and remediation suggestions by Gate
• Pass: Output a release certificate, confirming that it can be consumed by downstream as a new project governance baseline

AskUserQuestion Rules

• Only ask key questions that the reviewer cannot determine from the documents and repository facts
• Prioritize confirming: scope, target state, factual conflicts, blocking level
• If no_change the rationale is weak, must follow up with "why not update Guardrails"
• For the template, see references/askuser-templates.md

Prohibited Actions

• Do not write the rule body on behalf of the author
• Do not gloss over "factual standard conflicts"
• Do not review only the rule table without reviewing the trigger reasons and downstream hooks
• Do not degrade the reviewer into a format checker
• Do not relax the release threshold just because it is a governance document
