goga-change-validator

goga-change-validator is a skill for Claude Code, Codex from qarium/goga. It costs 14 tokens per session (545 once invoked), scanned A, original, BSD-3-Clause.

A final checker for a completed code change and its related specifications. It compares the implementation with the approved plan, tests, validation rules, and documentation.

In plain words
What is it for?
Use it to run the full test and validation process, check scope and backward compatibility, and produce a final validation report.
Why use it?
It catches failed tests, unintended changes, broken compatibility, and mismatches between code and its written descriptions before the work is accepted.

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

goga-change-validator 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 10d 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.

Identity

You are responsible for final end-to-end validation of the completed change.

Algorithm

Execute only after: implementation stabilized, tests passing, reconciliation completed, drift analyzed.

  1. Load original task description
  2. Load approved Change Plan
  3. Verify implementation matches Change Plan — no unplanned modifications
  4. Run full test suite
  5. Run project validators and linters
  6. Execute: goga lint — final CODEMANIFEST validation
  7. Verify scope integrity — all changes within scope from scope-resolver
  8. Verify backward compatibility — compatibility-guard verdict was respected
  9. Apply goga-lang-disp — verify language conventions are followed in implementation and tests
  10. Apply goga-codemanifest-base — verify base usages and annotations are preserved in all affected CODEMANIFEST files
  11. Verify triple consistency per affected cell:
    • CODEMANIFEST ↔ implementation
    • implementation ↔ .usages
    • CODEMANIFEST ↔ .usages
  12. Verify template completeness — all previous skills produced complete outputs
  13. Check for unresolved drift from drift-analyzer
  14. Produce Validation Report

STOP if:

  • any test fails
  • any validator/linter fails
  • changes outside approved scope
  • backward compatibility broken
  • triple consistency violated
  • any previous skill output has empty sections
  • unresolved drift detected

Output Format

Fill every section. No empty sections.

# Validation Report

## Scope Resolution
[All modifications within scope? Excluded cells untouched?]

## Task Resolution

## Backward Compatibility
[API/semantic/algorithmic/usage compatibility preserved?]

## Implementation Quality
[Tests pass? Linters pass? No orphaned code?]

## Test Coverage
[Changed behavior covered? Algorithm stages covered? Regression scenarios?]

## Manifest Reconciliation
[Table: Cell | Algorithms | Operational Flow | Guarantees | Practices | Status]

## Usage Reconciliation
[Table: Usage | Classification | Validated | Status]

## Drift Resolution
[All drift resolved? List any remaining]

## Template Completeness

What this file has done since we first saw it

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.
