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 | $0.00052 | $0.00346 |
| Opus 5 | $0.00026 | $0.00173 |
| Sonnet 5 | $0.00010 | $0.00069 |
| Haiku 4.5 | $0.00005 | $0.00035 |
Grade A, and why
cli 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.
What it actually says
CLI Development
Workflow
- Identify the command surface under
src/Apps/CommandLine. - Read command registration in
src/Apps/CommandLine/Program.cs. - Read the invoked service before changing command behavior.
- Keep command classes thin: parse settings, validate input, set context, call services, and format output.
Conventions
- Inherit from
AsyncCommand<TSettings>orAsyncCommand. - Put reusable behavior in CoreMod services, CodeGenerator, or Share instead of command classes.
- Use
CommandSolutionHelper.TrySetSolutionAsyncwhen the command needs a current solution. - Use
OutputHelperorAnsiConsoleconsistently with nearby commands. - Escape dynamic Spectre markup with
Markup.Escape. - Return
0for success and1for expected validation or operation failures. - Register new commands in DI and
CommandApp.Configure, including aliases, examples, and localized descriptions. - Preserve raw MCP/stdio command paths. Do not add logos, logs, or human-readable output that can break protocol clients.
Localization And Tests
- Add user-facing command text to both
src/Share/Localizer.zh-CN.resxandsrc/Share/Localizer.en-US.resx. - Add focused tests under
tests/StudioMod.Tests/Commandsfor command behavior, config output, or error handling.
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.

cli is a skill published in the GitHub repository AterDev/Perigon.CLI (53 stars, last pushed 3d ago), licensed Apache-2.0. It adds 52 tokens to every session and 346 once invoked, about $0.0003 per session on Opus 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 2026-08-30.
