6_gofer_validate

6_gofer_validate is a skill for Claude Code from eai-support/eai-gofer. It costs 17 tokens per session (8,049 once invoked), scanned A, original, Apache-2.0.

An engineering validation workflow that scores an implementation against ten quality areas using a 100-point rubric.

In plain words
What is it for?
Use it after development to run checks such as builds, tests, linting, type checks, mutation testing, mock-ratio analysis, and semantic-slop detection.
Why use it?
It creates a repeatable review gate for finding missing requirements, weak tests, build problems, and other implementation risks.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

6_gofer_validate scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 5d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Gofer Validate

You are validating that the implementation meets engineering quality standards using a 10-category rubric scored out of 100 points. This is the sixth stage of the unified Gofer pipeline.

A score of 100/100 is required to pass. Any category scoring 0 triggers failure and a brownfield restart loop.

User Input

$ARGUMENTS

You MUST consider the user input before proceeding (if not empty).

Prerequisites

This command expects in .specify/specs/{feature}/:

  • research.md - Codebase analysis (from $ $1_gofer_research)
  • spec.md - Feature specification (from $ $2_gofer_specify)
  • plan.md - Implementation plan (from $ $3_gofer_plan)
  • tasks.md - Task breakdown (from $ $4_gofer_tasks)
  • Implemented code (from $ $5_gofer_implement)

Outline

  1. Context health check
  2. Load implementation context
  3. Spawn 6 specialist validation agents in parallel
  4. Run automated checks (build, test, lint, typecheck)
  5. Mutation testing gate
  6. Mock ratio analysis
  7. Semantic slop detection
  8. Score the 10-category rubric
  9. Generate enhanced validation report
  10. Determine PASS/FAIL outcome
  11. Brownfield restart on failure
  12. Attribution logging to JSONL
  13. Memory update check

The Engineering Quality Rubric

10-Category Scoring (100 Points)

# Category Points Pass Criteria Agent
1 Functional Correctness 15 Every acceptance criterion in spec.md has a passing test exercising real code validation-correctness
2 Test Authenticity 15 Zero skips, zero placeholders, zero mock-only assertions. Mutation score >= 60% if Stryker available validation-test-quality
3 UI/E2E Verification 10 If feature has UI: real rendering tests pass. If no UI: points redistribute N/A (automated check)
4 Security Posture 10 Zero hardcoded secrets, no disabled security features, no client-side keys validation-security
5 Integration Reality 10 Integration tests use real dependencies where possible. Contract tests validate boundaries validation-integration
6 Error Path Coverage 10 Public functions tested for failure modes. No empty catch blocks validation-correctness + validation-standards
7 Architecture Compliance 10 File structure and patterns match plan.md and research.md validation-standards
8 Performance Baseline 5 No synchronous I/O in async paths, no unbounded loops, no N+1 patterns validation-performance
9 Code Hygiene 10 Zero AI slop: no TODO placeholders, no redundant comments, no magic numbers validation-standards
10 Specification Traceability 5 Every user story maps to tests, every test maps to code validation-correctness

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

6_gofer_validate is a skill published in the GitHub repository eai-support/eai-gofer (1 stars, last pushed yesterday), licensed Apache-2.0. It adds 17 tokens to every session and 8,049 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
