goga-change

goga-change is a skill for Claude Code, Codex from qarium/goga. It costs 12 tokens per session (894 once invoked), scanned A, original, BSD-3-Clause.

A workflow coordinator for maintenance changes that must follow written specifications. It keeps the code, the CODEMANIFEST, and Markdown usage records consistent while requiring each workflow stage to be checked before the next begins.

In plain words
What is it for?
Use it for specification-driven maintenance work, especially when resolving scope, following project DSL conventions, and updating implementation and usage records together.
Why use it?
It reduces the risk of making a code change that conflicts with its documented rules or leaves related project records out of sync.

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 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 the primary orchestration skill for specification-governed maintenance workflows.

Mission

Coordinate subskills in strict order while preserving triple consistency between:

  • CODEMANIFEST
  • implementation
  • .usages/*.md

Context Initialization

  1. Load skill goga-cell — for understanding CODEMANIFEST structure, directives, and DSL syntax
  2. Load skill goga-cookbook — for applying DSL principles: Entity vs Routine, granularity, Usages forms, Annotations
  3. Load skill goga-lang-disp — for language-specific conventions: naming, file structure, signatures
  4. Execute: goga schema
  5. Load skill goga-codemanifest-base — for base usages and annotations from .goga/config.yml
  6. Proceed to Pipeline Step 1

Pipeline

Execute each step strictly sequentially — one step at a time. After each step, verify its output before proceeding.

  • Each step MUST produce its own complete output before the next step begins
  • Execute each step as a separate distinct operation

Step 1. Scope Resolution

Invoke: goga-change-scope-resolver Output: Scope Resolution Report (all sections filled) STOP if: scope is empty, ambiguity unresolved, output sections missing

Step 2. Investigation

Invoke: goga-change-investigator (which internally invokes goga-change-tracer) Output: Investigation Report (all sections filled) STOP if: confidence LOW, breaking change detected, output sections missing

Step 3. Planning

Invoke: goga-change-planner Output: Change Plan (all sections filled) STOP if: plan conflicts with manifest, output sections missing WAIT: present plan to user, get approval before proceeding

Step 4. Compatibility Guard

Invoke: goga-change-compatibility-guard Output: Compatibility Report (all checkboxes answered) STOP if: any checkbox unchecked = BREAKING CHANGE = STOP pipeline

Step 5. Implementation

Invoke: goga-change-implementer Output: modified code STOP if: stabilization failure (MAX 5 iterations exceeded)

Step 6. Testing

Invoke: goga-change-test-engineer Output: test files + coverage report STOP if: coverage gaps for changed behavior

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.
