tandem_start

Starts an independent AI peer task from a prompt or structured contract and returns immediately; use preflight to inspect admission without launching a worker.

Instructions

Start a task with exactly one of prompt or structured contract. Returns immediately.

Base constraints/owned files stay fixed; each follow-up has a new goal and criteria. project_context_id pins product rules/decisions. Only the coordinator sets question timeout. Think: collaboration; analyze: read/search; work: edits/shell, NOT sandboxed. Use preflight=true to inspect admission without launching a worker. Structured requirements declare exact entry/boundary paths and shell/write needs; verification declares the agreed check ladder, never permission to execute it.

Tool call template

Replace each placeholder with a value matching the input schema. Only required parameters are included; add optional parameters as needed.

TDQS

A3.8/5.0
Behavior4/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations, the description carries the burden and does disclose non-obvious traits: the call returns immediately, work mode is NOT sandboxed, base constraints/owned files persist across follow-ups, preflight inspects admission without launching a worker, and verification declares the check ladder but never grants execution permission. Missing are failure/admission-rejection behavior and what the caller must do after the immediate return.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Purpose and the one-of-prompt-or-contract constraint are front-loaded in the first sentence, and most subsequent clauses carry distinct information. A few lines are terse to the point of being cryptic (the fixed base constraints sentence), costing some clarity.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

This is a high-complexity entry point with 11 params, no annotations, and a large nested contract schema whose own descriptions do heavy lifting. The description covers the contract and verification philosophy well but says nothing about the execution block or the review_id/review_stage pairing, which an agent needs to call this correctly in those paths. An output schema exists, so return values need not be described.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Top-level schema description coverage is 0% across 11 parameters, so the description has to compensate. It explains mode values, preflight, project_context_id, question_timeout_seconds (coordinator only), and the contract/requirements/verification intent, but leaves cwd, execution (model, profile, thinking, routing, timeout), review_id, and review_stage entirely undefined.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

Opening sentence gives a specific verb (start), resource (task), and an unusual hard constraint (exactly one of prompt or structured contract), plus async semantics (returns immediately). It does not name a sibling for contrast, so the boundary with tandem_continue or tandem_work is left partly implicit.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Gives real selection guidance: mode semantics (think = collaboration, analyze = read/search, work = edits/shell), preflight=true to inspect admission without launching, and 'each follow-up has a new goal and criteria' hinting at the follow-up path. It never explicitly names which sibling to use instead for follow-ups, waiting, or result retrieval, so it stops short of full routing.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
