goga-cell-cpp

goga-cell-cpp is a skill for Claude Code, Codex from qarium/goga. It costs 14 tokens per session (858 once invoked), scanned A, original, BSD-3-Clause.

A set of C++ rules for implementing contracts described in CODEMANIFEST files, which document expected code structure and behavior.

In plain words
What is it for?
Implementing C++ functions and classes while following declared usage patterns, using the required ownership conventions, and covering public code with tests.
Why use it?
It gives agents consistent guidance for C++ design, resource handling, memory layout, and testing.

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-cell-cpp 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 4d 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.

Examples

Full CODEMANIFEST example for C++ with all DSL constructs:

Imports:
  - Types:
      - Buffer
      - StreamConfig AS Config
    Usages:
      - memory_layout
    From: path/to/stream_cell

Usages:
  conventions: .goga/usages/cpp_conventions.md
  pattern: |
    Use RAII for resource management. Prefer stack allocation over heap allocation.
  testing: |
    Use Catch2. Each public function must have test coverage.

Annotations: |
  Use `conventions` for code style.
  Use `testing` for test requirements.
  Use `memory_layout` from Imports for buffer alignment rules.

  Use value semantics only. No raw pointers or references in public API.

---

"lookup_entry(std::string key) -> value: int":
  location: engine.hpp
  annotations: |
    Look up an entry by key.

    `key`: lookup key string
    `value`: found value or 0 if not found

    Use `pattern` for implementation.

"Parser(input: std::string)":
  location: parser.hpp
  annotations: |
    Configurable parser for structured input.

    `input`: raw input string

    Use `memory_layout` from Imports for buffer sizing.
    Use `conventions` for code style.
  properties:
    "position -> int": |
      Current parsing position.
    "length -> int": |
      Total input length.
  methods:
    "parse() -> tokens: std::vector<std::string>": |
      Parse input into tokens.

      `tokens`: parsed token list

      Use `pattern` for implementation.
    "reset()": |
      Reset parser state to beginning.

"Buffer::StreamBuffer(config: Config)":
  location: stream.hpp
  annotations: |
    Stream buffer extending Buffer with configurable capacity.

    `config`: buffer configuration from `Config` type.

    Use `memory_layout` from Imports for allocation strategy.

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-cell-cpp is a skill published in the GitHub repository qarium/goga (13 stars, last pushed today), licensed BSD-3-Clause. It adds 14 tokens to every session and 858 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 2026-08-30.
