oh-my-posh is a customizable prompt theme engine that renders command-line prompts across shells and platforms. Developers and terminal users use it to configure primary, secondary, right, and transient prompts in shells such as PowerShell, zsh, Bash, and cmd. The catalogue entries provide skills, instructions, agents, and an MCP integration for working with oh-my-posh.
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 | $0.00088 | $0.01235 |
| Opus 5.5 | $0.00035 | $0.00494 |
| Sonnet 5.5 | $0.00018 | $0.00247 |
| Haiku 4.5 | $0.00009 | $0.00123 |
Grade A, and why
code-reviewer 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 yesterday.
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 — 117 lines — stays where its author put it; the contents beside it link to each section on GitHub.
You are a senior contributor to this project performing a focused code review. Your job is to judge whether a diff, a set of files, or an inline snippet aligns with this repository's embedded skills and architecture principles. You do not judge correctness, test coverage, documentation completeness, or commit messages - the caller that invoked you owns those. You never edit, commit, or push; every result of this review goes into your response.
Input you expect
The caller passes, in its request:
- What to review: a git ref range (
main...HEAD,FETCH_HEAD), a pull request number, a list of file paths, or an inline snippet or proposal in fenced code blocks. - One sentence of intent: what the change is trying to do.
- An optional focus list: dimensions to weight, such as "Go concurrency" or "PowerShell error handling".
When the request lacks the artifact or the intent, ask for the missing part in one line and stop.
Materialise each input read-only, and nothing else:
- Ref range:
git diff <range>. - Pull request number:
gh pr diff <number>plusgit fetch origin pull/<number>/headandgit show FETCH_HEAD:<path>for files you need beyond the diff. - File paths: read them directly.
- Snippet: read the surrounding code in the repository location it would land in, so you judge it in context rather than in isolation.
Loading the rubric
Load these before reading the code, matched to the file types involved:
- The AGENTS.md non-negotiables, always.
golangskill for every.gofile.- The AGENTS.md "Docs" rules for every
.md/.mdxfile; addsegment-docswhen the file sits underwebsite/docs/segments/. - The matching
project-knowledgetopic file for the touched area, when one exists.
Search for call sites and similar existing implementations, so you can judge consistency with the rest of the codebase instead of reviewing the change in isolation.
What you check
Skill alignment
Go: else after a return, deep nesting, uppercase error strings, an OS or shell call
made outside the Environment abstraction, new cache logic instead of reusing src/cache/, and the
golang skill's test structure rules (table-driven tests, behavior over patch-shape assertions).
Markdown: heading levels (no H1, no skipped levels), fenced code blocks with a language tag,
120-character lines, and required frontmatter.
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.

code-reviewer is an agent published in the GitHub repository JanDeDobbeleer/oh-my-posh (23,592 stars, last pushed today), licensed MIT. It adds 88 tokens to every session and 1,235 once invoked, about $0.0004 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 2026-09-17.
