neneko-code-taste

neneko-code-taste is a skill for Codex from XnLemon/Neneko-skill. It costs 51 tokens per session (709 once invoked), scanned A, original, MIT.

A set of Go coding and review guidelines based on tRPC-Agent-Go's style. It helps keep changes small, clear, compatible, and tested at the level of the code's public contracts.

In plain words
What is it for?
Use it when adding or reviewing Go code for tRPC-Agent-Go or a project adopting its style. It guides API design, constructors, interfaces, focused patches, and contract-level tests.
Why use it?
It reduces the risk of breaking existing behavior or adding unnecessary abstractions. It also makes ownership, defaults, errors, cancellation, and resource lifetimes explicit.

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

neneko-code-taste 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.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/check.sh), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

How it starts

The opening of the file, as written. The whole thing — 70 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Neneko Code Taste

Apply this skill when the user wants new Go code or a review to feel native to tRPC-Agent-Go (or to a project deliberately adopting its engineering style). The goal is a small, clear, compatible change whose public API and lifecycle semantics are intentional. Treat the target repository's local conventions as the final authority when they conflict with an example below.

Working loop

Before editing:

  1. Identify the owning package and read its AGENTS.md, nearby constructors, options, interfaces, tests, and error paths. Search for an existing extension point before adding a new one.
  2. State the contract that must remain stable: defaults, nil behavior, errors, cancellation, ordering, resource lifetime, and exported API.
  3. Choose the smallest focused patch. Avoid unrelated refactors and avoid a new abstraction until its responsibility and ownership are clear.

While editing:

  • Prefer concrete constructors; introduce an interface only when a consumer needs substitution or multiple implementations, and keep it consumer-owned.
  • Keep implementation-specific types and configuration private to the owning package. Export only the narrow contract callers need.
  • Put context.Context first in methods that accept it; propagate cancellation and do not store contexts in structs.
  • Make goroutine, channel, timer, close, and shutdown ownership explicit. The creator owns cleanup unless the API documents a different contract.
  • Return wrapped errors with lowercase, punctuation-free messages; use %w when callers need to inspect the cause. Do not silently discard meaningful errors.
  • Match existing naming, option precedence, default initialization, copy/clone behavior, and Godoc/comment patterns.

After editing:

  1. Add or update tests that prove observable contracts (including defaults, invalid input, errors, cancellation, concurrency, and lifecycle where relevant), not merely line coverage or private implementation details.
  2. Run the narrowest relevant tests first, then repository formatting/import and lint checks. Use scripts/check.sh when it fits the target repository.
  3. Perform a second-pass API/design review of the final diff: exported surface, abstraction/ownership, compatibility, context propagation, concurrency, error semantics, and unrelated churn. Report residual risks explicitly.

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.
