project-conventions

project-conventions is a skill for Claude Code, Codex from alonf/specrew. It costs 12 tokens per session (346 once invoked), scanned A, a copy of project-conventions, MIT.

A placeholder guide for project-specific coding rules and habits. It is a starter template, so it does not currently describe real conventions for this codebase.

In plain words
What is it for?
Filling in project rules such as code style, tests, file locations, error handling, and examples.
Why use it?
There is not enough information here to guide an agent reliably beyond showing where conventions, testing, file structure, and error handling would be documented.

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

project-conventions 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 3d 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.

Origin

This is a copy

100% identical to project-conventions — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

What it actually says

Context

This is a starter template. Replace the placeholder patterns below with your actual project conventions. Skills train agents on codebase-specific practices — accurate documentation here improves agent output quality.

Patterns

[Pattern Name]

Describe a key convention or practice used in this codebase. Be specific about what to do and why.

Error Handling

Testing

Code Style

File Structure

Examples

// Add code examples that demonstrate your conventions

Anti-Patterns

Changes

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.
