What it does

Artifact Consistency Checker is an agent skill from GulajavaMinistudio/Mayukai-Theme. Performs consistency and traceability audits across documents (PRD vs Spec vs Plan) to detect missing coverage and scope creep.

Its SKILL.md is about 1.1k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Product & Project Management, covering PRD writing. It works with Visual Studio Code. The repository describes itself as: Combination theme for VS Code and VSCodium that inspired from Ayu Theme, Monokai , Andromeda, Material Color, and Gruvbox Darktooth Color. The licence is MIT.

When your agent uses it

  • Tasks that involve PRD writing

Example prompts

  • “Use the artifact-consistency-checker skill to perform consistency and traceability audits across documents (PRD vs Spec vs Plan) to detect missing…”
  • “/artifact-consistency-checker”

Workflow steps

3 steps, taken from the step headings in SKILL.md.

  1. Artifact Aggregation
  2. Tri-Directional Audit
  3. Reporting & Corrective Action

What it can do on your machine

Read from SKILL.md and the folder at commit c8c9159. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md (its code samples are diff).

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Artifact Consistency Checker loads about 1.1k tokens when it runs. Until then it costs about 39 tokens; SKILL.md has 487 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~39
When it runs · the whole SKILL.md, loaded when a task matches
~1.1k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Artifact Consistency Checker Skill

Overview

This skill focuses on verifying the traceability and consistency of your Software Development Life Cycle (SDLC) artifacts. It is used to ensure that no single requirement is missed, and no "dark features" are added without justification when moving from the PRD document, to the Technical Specification, and finally to the Implementation Plan. This skill accompanies the @ArtifactConsistencyChecker agent.

When to Use

Use this skill when:

  • The user has finished creating the Implementation Plan and is ready to start coding (invoking @GodModeDev).
  • The team suspects an indication of scope creep (features being added silently without business approval).
  • There is confusion regarding which document is the latest Source of Truth.
  • The user specifically requests an "audit", "consistency check", "traceability review", or "traceability matrix".

Operational Workflow

Phase 1: Artifact Aggregation

Collect all documents related to the current feature in progress. You must read and retain the context of at least TWO of the following documents to perform a comparison:

  1. PRD (e.g., prd-feature-*.md) (Upstream Document / Business Needs)
  2. spec-*.md (Middle Document / Architectural Specs)
  3. plan-*.md (Downstream Document / Implementation Plan & Tasks)
Phase 2: Tri-Directional Audit

Perform a rigorous point-by-point mapping:

  • Upstream to Downstream (Missing Coverage): Take requirement X in the PRD, check if requirement X has an architectural design in the Spec, and has an explicit execution task in the Plan.
  • Downstream to Upstream (Orphaned Items): Take task Y in the Plan, trace upwards (to Spec/PRD) to see who requested task Y. If no one requested it, this is scope creep.
  • Lateral (Contradictions): Look for specific parameters (file size limits, time limits, SLAs, frameworks) and ensure the numbers are consistent and do not contradict each other across all documents.

Phase 3: Reporting & Corrective Action

Create an audit report using the Consistency Audit Report format. If the audit status is FAIL or there are major issues, deny the user permission to proceed to the next phase. The user must align and correct the faulty documents first.

Consistency Quality Standards

Detecting Scope Creep (Orphaned Items)

Look for technical tasks that are excessive and have no foundation or were never requested by business documents.

diff
# Example in Plan (BAD)
- Setup a Kubernetes cluster with 3 nodes for auto-scaling.
- Setup a separate Redis Cluster for caching search responses.

# Challenge/Audit (GOOD)
+ Did the PRD request this level of performance and scalability? The PRD only states "Internal app for a maximum of 5 concurrent users".
+ Therefore, Kubernetes and Redis are Orphaned Items (potential Over-engineering).
Detecting Missing Coverage

Look for sweet promises in the PRD that are never technically executed in the planning stage.

diff
# Example in PRD (Upstream)
- Users must receive an email notification immediately when their PDF file finishes compressing.

# Example in Plan (Downstream) (BAD)
- 1. Create upload UI page
- 2. Implement compression using PDF.js module
- 3. Provide a download button at the end of the process

# Challenge/Audit (GOOD)
+ The email sending feature (e.g., SMTP integration) is completely missing in the Plan. This is Missing Coverage!

Implementation Guidelines

DO (Always)
  • Enforce Traceability: Whenever you validate a Plan, ensure you can point exactly to the sentence or ID in the PRD/Spec that justifies the task.
  • Block (Halt) the Coding Process: Apply a halt status on development if the documents are still fundamentally contradictory.
DON'T (Avoid)
  • Subjectively Evaluating Architecture Quality: Do not complain if the user plans to use React instead of Vue, UNLESS the PRD/Spec documents specifically forbid it. Your focus is strictly "Are these documents aligned?".
  • Auto-Fix (Fixing it yourself): Do not unilaterally modify and overwrite PRD or Plan documents to force content alignment without user approval. You cannot know for sure which document (Upstream or Downstream) represents the user's true intention.
