Kalpana Batch

Edit a batch

update_batch

Destructive

Renames a batch and changes, adds, or removes its pending jobs in one request. update merges each listed job's modifications over its own (a key given again replaces it, null clears it back to the page's value) and replaces the output fields given; unlisted jobs are untouched. remove deletes those pending jobs permanently, and add creates new jobs from rows on pages, templates or a flow, as create_batch does, so repeating a request with add duplicates them. Processing, rendered and failed jobs cannot change, and an archived batch does not change. Nothing renders until run_batch, and adding or removing jobs changes what it costs. Needs templates:read and batches:create.

Tool call template

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

A4.6/5.0

Behavior5/5

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

Annotations already declare destructive and non-idempotent, and the description justifies both: remove deletes permanently, and repeating a request with add duplicates jobs. It further discloses that update merges over existing values, that null reverts to the page default, that unlisted jobs are untouched, that adding/removing changes cost, and the required scopes templates:read and batches:create.

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?

One dense paragraph with every sentence carrying merge semantics, immutability rules, rendering timing, cost, or scopes — no filler. It would read better front-loaded into separate sentences per operation (update/remove/add), since the merge rules currently sit inside a long clause.

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

Completeness5/5

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

For a five-parameter tool with deep nested objects and an output schema, the description covers the merge/overwrite contract, destructiveness, duplicate-on-retry behavior, what is immutable, deferred rendering, cost impact, and required scopes. Nothing an agent needs to call it safely is missing.

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

Parameters4/5

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

Coverage is 100%, so the baseline would be 3, but the description adds genuine semantics the schema cannot express: update applies modifications over each job's own values, a repeated key replaces, null clears back to the page's value, and output fields are replaced rather than merged. It does not spell out remove's UUID expectations or the per-array caps beyond what the schema says.

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

Purpose5/5

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

Opens with a specific verb+resource+scope: 'Renames a batch and changes, adds, or removes its pending jobs in one request.' The three mutation modes are named, and the reference 'as create_batch does' lets an agent distinguish the add path from create_batch and update_job without opening schemas.

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?

Explicitly states what cannot be edited ('Processing, rendered and failed jobs cannot change, and an archived batch does not change') and that nothing renders until run_batch. It stops short of naming the alternative tools for single-job edits (update_job) or giving an explicit 'do not use when' routing statement, so it is strong context rather than full alternative mapping.

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