[rig-claude] Improve Claude dynamic-workflow compatibility for rig

[github-actions]

Compatibility gap addressed

Claude dynamic-workflow users know how to select models with { model: "sonnet" } and quality with { effort: "high" }, but the conversion reference didn't show:

1. How to configure rig to run on Claude / Anthropic (which engine, which env var)
2. Which full Claude model IDs to use (the primitive table just said "rig passes the id straight to the engine")
3. What to do instead of effort: "high" (the table said — with no actionable guidance)

This is the single highest-confidence discoverability gap: a user porting a Claude workflow would copy model: "sonnet" and wonder why it doesn't resolve, then have no docs pointing them to anthropicEngine() or claude-sonnet-4-5.

Why this improves transfer

• Adds a concrete "Running with the Anthropic engine" section with a configureAgent(anthropicEngine()) snippet, RIG_ENGINE=anthropic note, and a model tier table (haiku/sonnet/opus)
• Makes the effort row actionable: "use a more capable model id or increase maxTurns"
• Expands the model row note to surface the full-id requirement with anthropicEngine()
• Updates the SKILL.md focused-reference blurb to surface "model selection" so agents load this reference when the task involves Anthropic

Files changed

• skills/rig/references/claude-workflow-conversion.md — new section + expanded table rows
• skills/rig/SKILL.md — blurb update for the claude-workflow-conversion reference

Validation

Docs-only change; no typecheck or test run required per the validation rules. Checked for broken relative links — all sample and reference links are unchanged.

Remaining intentional differences

• No effort field in rig (by design); the guidance now directs users to the model tier table instead.
• No agentType: "Explore" equivalent; the existing guidance (prompt wording + narrow tools list) remains correct.

Skills-Based Review 🧠

Applied /grill-with-docs — requesting changes on two correctness issues in the new section.

📋 Key Themes & Highlights

Issues

• Incorrect call usage (line 184): call is not a named export from "rig" — it is a destructured parameter in a workflow body. The snippet imports { agent, s, workflow } but uses call as a free function, which is a ReferenceError.
• Inaccurate RIG_ENGINE description (line 169): described as "auto-select" when it is actually an explicit override. True auto-selection happens when RIG_ENGINE is absent and ANTHROPIC_API_KEY is set.

Positive Highlights

• ✅ The overall structure of the new section is well-targeted; it fills a real discoverability gap
• ✅ The model tier table is clear and useful
• ✅ The effort row expansion gives actionable guidance where before there was none
• ✅ SKILL.md blurb update correctly surfaces "model selection" for routing

[/grill-with-docs] call is not a named export from "rig" — it is only available as a destructured parameter inside a workflow body (body: async ({ call }) => { ... }). Using it as a standalone function will cause a ReferenceError at runtime and mislead readers porting Claude workflows.

💡 Suggested fix

Either wrap the per-call override in a workflow body:

const myWorkflow = workflow({
  input: s.object({ text: s.string }),
  body: async ({ call }, { text }) => {
    return await call(classifier, { text }, { model: "claude-opus-4-5" });
  },
});

Or use the callable AgentFn signature directly (since AgentFn is callable):

const result = await classifier({ text }, { model: "claude-opus-4-5" });

[github-actions]

[/grill-with-docs] Slight inaccuracy: RIG_ENGINE=anthropic is an explicit override, not auto-selection. Auto-selection happens when RIG_ENGINE is not set and ANTHROPIC_API_KEY is present. Swapping the description avoids confusion for users who rely on env-based auto-detection.

💡 Suggested wording

Or omit `configureAgent` entirely — if `ANTHROPIC_API_KEY` is set and `COPILOT_SDK_URI` is not,
rig auto-selects the Anthropic engine. Set `RIG_ENGINE=anthropic` to force it explicitly.
