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

[github-actions]

Compatibility gap addressed

The primitive mapping table in skills/rig/references/claude-workflow-conversion.md was missing the until() convergence primitive. A developer porting a Claude dynamic workflow that uses an open-ended while loop for bounded retries or convergence (e.g. "keep fixing until tests pass, up to 8 rounds") would not discover until() and might write an unbounded loop instead.

Why this improves transfer

until is the exact rig idiom for the "bounded convergence loop" pattern that is common in Claude dynamic workflows. The table already covered every other major primitive (parallel, pipeline, phase, log, budget, nested workflow, schema-constrained calls, per-call options). Adding until closes the last visible gap in the conversion surface.

Files changed

• skills/rig/references/claude-workflow-conversion.md — added one row to the primitive mapping table:

  | open-ended while convergence loop | until({ max, noProgressRounds }, step) | Bounded; stops on done, after max rounds, or after noProgressRounds equal progress keys — prefer over unbounded loops |

Validation

Only documentation changed. Verified:

• No broken relative links (existing links to dynamic-workflows.md, agent-api.md, and runtime.md unchanged).
• wc -l went from 155 → 156 lines (one added row).

Remaining intentional differences

All previously documented differences are unchanged:

• { effort: "high" } has no rig equivalent (encode structurally or in model id)
• { agentType: "Explore" } has no built-in read-only agent type
• No sandbox restrictions, resume journal, worktree isolation, or human checkpoints

Skills-Based Review 🧠

Applied /grill-with-docs — this is a clean, accurate documentation addition.

📋 Key Themes & Highlights

Positive Highlights

• ✅ The new row correctly identifies until({ max, noProgressRounds }, step) as the rig idiom for bounded convergence loops
• ✅ Placement is consistent — inserted between the workflow() row and top-level return, which is the logical location for a loop primitive
• ✅ The notes column accurately summarises the three stopping conditions (done, max, noProgressRounds) matching dynamic-workflows.md
• ✅ The "prefer over unbounded loops" guidance aligns with how until is presented in the reference docs

No issues found. The addition closes the last visible gap in the primitive mapping table.
