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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00047 | $0.00614 |
| Opus 5 | $0.00023 | $0.00307 |
| Sonnet 5 | $0.00009 | $0.00123 |
| Haiku 4.5 | $0.00005 | $0.00061 |
Grade A, and why
oh-my-posh scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 12d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
What it actually says
Oh My Posh
Oh My Posh is a cross-shell, cross-platform prompt theme engine. It displays Git status, language versions, cloud context, system metrics and more in a beautifully themed terminal prompt — 118 segments in all.
How to use this skill
-
Identify the user's OS → follow the matching installation guide:
-
Identify the user's shell → follow the matching shell setup guide:
-
Install a Nerd Font — required for icons and glyphs:
oh-my-posh font install meslooh-my-posh font listprints every installable font. Recommended: Meslo LGM NF. Set it in the terminal emulator's font settings after installing. -
Customize the prompt → see configuration
Detect the current shell
If the user is unsure which shell they are using (requires oh-my-posh to be installed first):
oh-my-posh get shell
Troubleshooting
- Icons show as boxes — install a Nerd Font and set it in the terminal emulator.
oh-my-poshnot found after install — restart the terminal or add the install path to$PATH.- Slow prompt -- enable async rendering by setting
"async": trueat the top level of your config.

What ships with it
13 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

pi-loop-forensics
Diagnose pi-go agent loops and degenerate turns — "agent loop aborted", runaway thinking with no tool calls, repeated phrases. Discriminates genuine model repetition collapse from a race, a tool-parse failure, or a too-low guard, and A/B replays a seed session across providers.
nightly-session-watch
Nightly sweep of the last 24h of pi-go sessions — anomalous runs, loop aborts, tool error rates, token waste, real prompt-token spend, and whether the observation and palace pipelines are still recording. Triages each finding to the specialist skill that diagnoses it. Use for an unattended daily health check, or on…
