[rig-tasks] Daily rig evaluation — 2026-08-23 — 10/10 passed

[github-actions]

Summary

Task	Description	Kind	Typecheck	Key finding
1 (reused)	Shell shebang glob validator	agent	✅ pass	Clean use of p.glob + defineTool + repair(); shebangLine typed as s.optional(s.string) correctly
2 (reused)	Git log graph summarizer	agent	✅ pass	steering()+repair() addon order correct; handler return typed with as const
3 (reused)	TypeScript complexity scorer	agent	✅ pass	s.record + s.enum for complexity; topContributors s.array(s.string) well-formed
4 (reused)	Parallel multi-tool workflow	workflow	✅ pass (after fix)	Initial use of call/parallel imported from "rig" — these are destructured from body args; also parallel requires homogeneous return types
5 (reused)	Zlib compression analyzer	agent	✅ pass	node:zlib deflateSync usage correct; compressionClass s.enum with 4 values
6 (reused)	File crypto hash reporter	agent	✅ pass	node:crypto createHash with optional algorithm input; s.record output well-formed
7 (new)	Source line length auditor	agent	✅ pass	p.glob + defineTool; worstLineNumber s.int correctly used
8 (new)	Workspace symlink inventory	agent	✅ pass	p.bash find -type l; readlink/realpath in tool handler; broken s.boolean
9 (new)	XML attribute extractor	agent	✅ pass (after fix)	Unused variable tagPattern caused TS6133; removed to fix
10 (new)	YAML anchor alias reporter	agent	✅ pass	p.glob for both .yml and .yaml; regex anchor/alias detection; steering()+repair()

Problems encountered

Task 4 — Parallel multi-tool workflow (3 failures before pass)

What it tried to do: A workflow that runs two agents (fileCountAgent, envHealthAgent) with parallel() and combines results.

Error 1: Module '"rig"' has no exported member 'call' — call and parallel are not top-level "rig" exports; they are destructured from the body async function parameters.

Error 2: parallel in rig requires all thunks to return the same type (homogeneous array). Running two agents with different output schemas via parallel() causes a TypeScript error.

Fix: Switched from parallel() to sequential await call(...) calls, which avoids the type constraint and is clearer anyway.

Error 3: meta required a description field — WorkflowMeta requires both name and description.

Root cause: The call/parallel API is destructured from body parameters, and parallel is typed for homogeneous arrays. The SKILL.md mentions this but the distinction is easy to miss.

Task 9 — XML attribute extractor (1 failure before pass)

What it tried to do: An agent with a defineTool parseXmlAttributes that uses regex to scan XML.

Error: TS6133: 'tagPattern' is declared but its value is never read — a leftover regex variable was declared but superseded by another pattern.

Fix: Removed the unused tagPattern variable.

Improvement opportunities

Missing or undiscoverable schema helpers (s.*)

No missing helpers encountered. s.record, s.optional, s.enum, s.int, s.number, s.path, s.array, s.boolean, s.string all worked cleanly.

Missing or undiscoverable prompt helpers (p.*)

p.readInput was used for reading a caller-supplied file path (task 9). This is correct but easy to confuse with p.read. The SKILL.md table covers this, but a short note clarifying "use p.readInput when the file path comes from input, not a known literal" would help.

Error message quality

• 'call' is not exported from 'rig': When a developer imports call at the top of a workflow file, the error says it's not exported but doesn't hint that it's available via body destructuring. A more helpful error: "Did you mean to destructure call from the workflow body parameters?"
• WorkflowMeta.description missing: Reasonable error, but SKILL.md doesn't show description in the workflow example — only in the reference files.

API ergonomics

1. parallel() homogeneous type constraint: Running two agents with different output types via parallel() fails. Developers naturally want to parallelize heterogeneous agents. A parallelAll variant or typed tuple overloads would improve ergonomics.
2. workflow meta.description required: Having description be required is strict; it's not shown in the canonical example. Either make it optional or add it to the SKILL.md canonical workflow snippet.
3. call in workflow body: The body-destructuring pattern for call/parallel/phase is non-obvious for developers familiar with top-level imports. A note in SKILL.md like "workflow body receives { call, parallel, phase, pipeline } — do not import these from 'rig'" would prevent repeated mistakes.

Candidate lint rules

Rule: no-top-level-workflow-call-import

• Invalid: import { call, parallel } from "rig" inside a workflow file
• Valid: body: async ({ call, parallel }) => { ... }
• Why model-confusing: The rig runtime provides call/parallel via body parameters for workflow context routing; top-level imports don't exist and produce a confusing "not exported" error.
• Autofix possible: Yes — remove the import and add destructuring to the body signature if missing.

Documentation gaps

1. SKILL.md canonical workflow example should include description in meta since it's required.
2. The note "do not import call/parallel from 'rig' inside workflow files" should appear in the construction rules section.
3. parallel() type homogeneity constraint should be documented with an explicit note and a workaround (sequential calls or Promise.all with explicit typing).
