giselle: Skill for Claude Code

.claude/skills/add-model/SKILL.md

add-model is a skill for Claude Code from giselles-ai/giselle. It costs 45 tokens per session (750 once invoked), scanned A, original, Apache-2.0.

A code guide for adding a language model, an AI model that generates or understands text, to the Giselle codebase.

In plain words
What is it for?
Use it to register OpenAI, Anthropic, or Google models, define their limits and capabilities, update configuration, and run project checks.
Why use it?
It gives developers the required model details and the files that must stay consistent when a provider adds a model.

Skill for Claude Code

Written for Claude Code: installed under .claude/.

This is giselles-ai/giselle's own configuration. It tells Claude Code how to work on giselle itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything giselle configures →

Token cost

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.

ModelPer sessionOnce invoked
Fable 5.1 $0.00045 $0.00750
Opus 5.5 $0.00018 $0.00300
Sonnet 5.5 $0.00009 $0.00150
Haiku 4.5 $0.00005 $0.00075

Security

Grade A, and why

add-model 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 2mo 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.

Add Language Model

Add a new language model to the Giselle codebase with full system consistency.

Quick Start

  1. Gather model specifications (or search web for official docs)
  2. Update files in order listed below
  3. Run validation: pnpm format && pnpm build-sdk && pnpm check-types && pnpm tidy && pnpm test

Required Information

Before starting, collect:

  • Provider: openai, anthropic, or google
  • Model ID: e.g., "gpt-5.3", "claude-opus-5"
  • Context window: Maximum input tokens
  • Max output tokens: Maximum output tokens
  • Knowledge cutoff: Date of training data cutoff
  • Pricing: Input/output cost per million tokens
  • Capabilities: Reasoning, image input, web search, etc.
  • Configuration options: Reasoning effort levels, verbosity, temperature, etc.

Files to Update (In Order)

1. Language Model Registry (Primary Definition)

File: packages/language-model-registry/src/{provider}.ts

Add the model definition. See REGISTRY.md for detailed examples.

2. Language Model Package

File: packages/language-model/src/{provider}.ts

Update three locations:

  1. Add to the enum (e.g., OpenAILanguageModelId)
  2. Add regex catch for dated versions in .catch() block
  3. Create model instance and add to models array

See LANGUAGE-MODEL.md for detailed examples.

3. Model Pricing

File: packages/language-model/src/costs/model-prices.ts

Add pricing entry to the appropriate table. See PRICING.md.

4. AI SDK Transformation

File: packages/giselle/src/generations/v2/language-model/transform-giselle-to-ai-sdk.ts

Add model ID to the switch case for the provider.

5. Node Conversion

File: packages/node-registry/src/node-conversion.ts

Add bidirectional conversion:

  • Short to full: case "model-id": return "provider/model-id";
  • Full to short: case "provider/model-id": return "model-id";

6. UI Configuration (If Needed)

File: internal-packages/workflow-designer-ui/src/editor/properties-panel/text-generation-node-properties-panel/model/{provider}.tsx

What ships with it

7 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.

Changes

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.
