goga-prototype-contracts

goga-prototype-contracts is a skill for Claude Code, Codex from qarium/goga. It costs 18 tokens per session (1,387 once invoked), scanned A, original, BSD-3-Clause.

A contract-design workflow for deciding which practices, dependencies, and implementation instructions belong to each code cell. A code cell is a defined project component described by a CODEMANIFEST file.

In plain words
What is it for?
Use it to design per-cell usages, annotations, and consumer documentation while following the project's manifest and documentation rules.
Why use it?
It provides a consistent way to turn type details and project rules into contracts that another developer can implement.

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-prototype-contracts 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 14d 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 determining, per cell, which practices (usages), instructions (annotations at all levels), and consumer usage files.

Context

Use these skills for every design decision (never improvise annotation or usage decisions from memory):

  • goga-cell — the DSL specification: the exact syntax and semantics of the Annotations, Usages, Imports, Entity, Routine, Mutation, and Embedding directives — what may appear in a CODEMANIFEST and how it is written.
  • goga-cookbook — the principles of applying that DSL: the annotation levels (global / type-level / member-level), the annotation writing standard (good-practice elements — description, Algorithm:, Requirements:, Constraints: — applied by the sufficiency criterion, not a fixed structure), that annotations must not duplicate each other or carry implementation details, that a connected practice applies only via an annotation, and the rules for writing <cell_path>/.usages/ files. Use it to decide how to phrase annotations, where each instruction belongs, and how to write consumer usage files.
  • goga-codemanifest-base — the project's base usages and annotations (from .goga/config.yml) that every CODEMANIFEST must include and comply with.
  • goga-lang-disp — naming and signature conventions for the target language (routes to the per-language skill).

Use these reports for its specific purpose:

  • [CELL_DISTRIBUTION_REPORT] — use it for the distribution of types across cells, the inter-cell Imports connections, and which cells are modified vs created anew — the structure to attach contracts to (drives the usages-inline sub-skill).
  • [TYPE_DETAIL_REPORT] — use it for each type's responsibility, methods/properties/signatures, and * interactions* — the factual basis the sub-skills use for annotations and consumer usage examples.

Workflow

Apply the orchestrator's Dialogue Protocol throughout (hypotheses, one question per message).

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.

goga-prototype-contracts is a skill published in the GitHub repository qarium/goga (43 stars, last pushed today), licensed BSD-3-Clause. It adds 18 tokens to every session and 1,387 once invoked, about $0.0001 per session on Opus 5.5. 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 2026-10-02.
