Delete a session

spicrawl_session_delete

DestructiveIdempotent

Permanently delete a session and its stored state, including the record itself (prefer spicrawl_session_release if you only want to stop using it). Idempotent: deleting an already-deleted session succeeds. Refused while a scrape holds the session's lease unless force is true.

Tool call template

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

Input Schema

Name	Required	Description	Default
`force`	No	Break an active lease (a scrape currently using the session). Only set when you know it is safe.
`session_id`	Yes	The session id returned by spicrawl_session_create or spicrawl_session_list.

Output Schema

Name	Required	Description	Default
`deleted`	Yes	Always true on success (deleting an already-deleted session succeeds).
`session_id`	Yes	The id that was deleted.

A4.7/5.0

Behavior5/5

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

Annotations already flag destructive=true and idempotent=true, but the description adds real behavioral context beyond them: what gets destroyed (the record and stored state), that repeat deletes succeed, and that deletion is refused while a scrape holds the lease unless force is set.

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

Conciseness5/5

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

Three tight sentences with zero waste; the destructive scope is front-loaded, followed by the alternative and then edge-case behavior.

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?

With an output schema covering return values and annotations covering safety, the description supplies everything else an agent needs: destruction scope, idempotency, lease precondition, and escape hatch.

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?

Schema description coverage is 100%, so both parameters are already documented in the schema. The description reinforces the force semantics ('unless force is true') but adds no syntax or format detail beyond what the schema provides; baseline 3 applies.

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?

States a specific verb+resource ('Permanently delete a session and its stored state') and explicitly scopes it against the sibling spicrawl_session_release, so an agent can differentiate without opening either schema.

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

Usage Guidelines5/5

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

Names the alternative explicitly ('prefer spicrawl_session_release if you only want to stop using it') and states the selection condition, plus the refusal precondition involving an active lease. When-to-use and when-not-to-use are both covered.

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