Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00016 | $0.02631 |
| Opus 5 | $0.00008 | $0.01316 |
| Sonnet 5 | $0.00003 | $0.00526 |
| Haiku 4.5 | $0.00002 | $0.00263 |
Grade A, and why
pre-commit-review 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 5d 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.
This is a copy
98% identical to pre-commit-review — 12 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.

Name
code-review:pre-commit-review
Synopsis
/code-review:pre-commit-review [--language <lang>] [--profile <name>] [--skip-build] [--skip-tests]
Description
The code-review:pre-commit-review command performs a comprehensive code quality review of staged and unstaged changes before committing. It analyzes unit test coverage, idiomatic code patterns, DRY compliance, SOLID principles, and build verification.
The command supports two layers of customization:
-
Language skills (
--language <lang>): Load language-specific guidance for idiomatic code review, test conventions, and build commands. Currently shipped:go. Planned:python,rust,typescript,java. If not specified, the language is auto-detected from changed file extensions. -
Profile skills (
--profile <name>): Load project-specific guidance that layers on top of language checks. Profiles add project conventions, shared utilities, build targets, and additional review criteria. Profiles reference the project's own agents and skills rather than embedding them.
The two layers compose: --language go --profile hypershift applies both Go idioms and HyperShift project conventions.
Implementation
Step 0 — Parse Arguments & Load Skills
- Parse
$ARGUMENTSfor the following flags:--language <lang>: Language skill to load (e.g.,go,python,rust,typescript,java)--profile <name>: Project profile skill to load (e.g.,hypershift)--skip-build: Skip build verification step--skip-tests: Skip unit test coverage review step
- If
--languageis not specified, auto-detect the primary language from the file extensions of changed files:.go->go.py->python.rs->rust.ts,.tsx->typescript.java->java- If mixed or unrecognized, proceed without a language skill
- Check for the language skill file at
skills/lang-<lang>/SKILL.mdrelative to the plugin root directory. If the skill exists, read it and store its content for use by sub-agents. If it does not exist, inform the user and proceed with a generic review. - If
--profileis specified, check for the profile skill file atskills/profile-<name>/SKILL.mdrelative to the plugin root directory. If the skill exists, read it and store its content for use by sub-agents. If it does not exist, warn the user and proceed without profile-specific checks.
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.
