What it does

Pi Custom Model is an agent skill from sickn33/agentic-awesome-skills. Register custom Pi Agent model slugs so saved OpenRouter variants resolve correctly.

Its SKILL.md is about 1.1k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in AI & LLM Engineering, covering Model routing and gateways. It works with OpenRouter. The repository describes itself as: AAS Core is the local, agent-first control plane for complete catalog discovery, agent-owned selection, stack validation, and planning, backed by 2,400+ agentic skills. Includes… The licence is MIT.

When your agent uses it

Tasks that involve Model routing and gateways

Example prompts

“/pi-custom-model”

Requirements

A credential in OPENROUTER_API_KEY

Workflow steps

5 steps, taken from the first numbered list in SKILL.md.

Confirm the slug is real before adding it (e.g. check the OpenRouter model/variant exists). A typo'd id also silently falls back.
Confirm auth. The provider must have a key in auth.json (or an env var like OPENROUTER_API_KEY). No auth → the model is registered but…
Add the model to models.json under providers..models. For a built-in provider (openrouter, anthropic, etc.) you only supply metadata…
Set the default in settings.json: defaultProvider + defaultModel = the exact id. Leave defaultThinkingLevel as the user has it.
Verify: pi --list-models | grep shows it, and JSON parses. Optionally smoke-test: pi --provider --model "" "which model are you?".

What it can do on your machine

Read from SKILL.md and the folder at commit 680176d. It shows what the files ask for, not the result of running them.

Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md (its code samples are json).
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names these keys or tokens, usually read from environment variables:
- OPENROUTER_API_KEY
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Pi Custom Model loads about 1.1k tokens when it runs. Until then it costs about 25 tokens; SKILL.md has 407 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~25
When it runs · the whole SKILL.md, loaded when a task matches: ~1.1k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Pi custom / variant model

When to Use

Pi's saved default only loads if the exact provider/id exists in its model registry. Pi ships a static bundled list per provider — so OpenRouter routing-shortcut variants (:nitro = sort by throughput, :floor = cheapest, :exacto = quality tool-use) and any brand-new slug are NOT in it. When the default doesn't resolve, Pi silently falls through to its built-in per-provider default (for openrouter that's moonshotai/kimi-k2.6) — looking like Pi "reset" your model. Fix = register the slug as a custom model so find(provider, id) matches.

Files (global)

~/.pi/agent/settings.json — defaultProvider, defaultModel, defaultThinkingLevel
~/.pi/agent/models.json — custom models, keyed by provider
~/.pi/agent/auth.json — provider credentials (check the provider key exists)

Steps

Confirm the slug is real before adding it (e.g. check the OpenRouter model/variant exists). A typo'd id also silently falls back.
Confirm auth. The provider must have a key in auth.json (or an env var like OPENROUTER_API_KEY). No auth → the model is registered but unavailable → still falls back.

Add the model to models.json under providers.<provider>.models. For a built-in provider (openrouter, anthropic, etc.) you only supply metadata — api, baseUrl, and auth are inherited from the bundled defaults. Example:

json

{
  "providers": {
    "openrouter": {
      "models": [
        {
          "id": "z-ai/glm-5.2:nitro",
          "name": "Z.ai: GLM 5.2 (nitro)",
          "reasoning": true,
          "thinkingLevelMap": { "xhigh": "xhigh" },
          "input": ["text"],
          "cost": { "input": 0.95, "output": 3, "cacheRead": 0.18, "cacheWrite": 0 },
          "contextWindow": 1048576,
          "maxTokens": 32768,
          "compat": { "supportsDeveloperRole": false, "thinkingFormat": "openrouter" }
        }
      ]
    }
  }
}

Copy cost/contextWindow/compat from the base model (the variant shares them) — find the bundled entry in <pi-pkg>/node_modules/@earendil-works/pi-ai/dist/providers/<provider>.models.js. Don't hardcode generic 128k/16k if the real model is bigger.

Set the default in settings.json: defaultProvider + defaultModel = the exact id. Leave defaultThinkingLevel as the user has it.
Verify: pi --list-models | grep <id> shows it, and JSON parses. Optionally smoke-test: pi --provider <p> --model "<id>" "which model are you?".

Quirks

Exact match only. find() is exact provider+id — no fuzzy/colon-stripping for the saved default path. The slug in settings.json and models.json must be byte-identical.
Silent fallback. Pi prints no error when the default doesn't resolve; it just shows a different model in the footer. That's the tell.
Don't edit settings.json alone. Setting defaultModel to an unregistered slug does nothing — models.json is the actual fix.
enabledModels (optional) pins the model picker so Ctrl+P cycling can't drift back: "enabledModels": ["<provider>/<id>:<thinking>"].
Project override. A repo's .pi/settings.json overrides global. If a default reverts only inside one project, check that file first.
Restart Pi fully — the registry loads at startup.

Example

Limitations

Adapted from davidondrej/skills; verify local paths, tools, credentials, and agent features before acting.
For commands, remote access, scheduling, browser automation, or file-changing workflows, get explicit user approval and confirm the target environment first.
