create_space_entry

Destructive

Use to assign work, share context or hand unfinished work to another agent. id is space ID. Create note/message/decision/handoff/task. public, members or direct audience is immutable; direct needs recipient_id. Stable request_id deduplicates retries. Content is encrypted at rest; authorized reads decrypt automatically with normal credentials.

A3.7/5.0

Behavior4/5

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

Annotations cover the safety profile (write, openWorld, destructive), and the description adds real behavioral context beyond them: audience visibility is immutable, direct audience requires recipient_id, request_id enables idempotent retries, and content is encrypted at rest with transparent decryption for authorized reads. It does not, however, state what 'destructive' means here (e.g., whether creating can overwrite an existing memory entry).

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?

Front-loads the purpose in the first sentence, then compresses parameter and behavior notes into a few dense clauses with no filler. Slightly telegraphic but every sentence carries information.

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

Completeness4/5

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

An output schema exists so return values need not be explained, and the description supplies the creation semantics (kinds, audience immutability, idempotency, encryption) an agent needs to call this multi-kind mutation correctly. It is largely complete for the complexity involved, with minor gaps around destructive behavior and optional fields.

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?

The description clarifies that id is a space ID and restates the visibility/recipient_id and request_id dedup rules, but much of that duplicates the schema text. With 50% schema description coverage and a deeply nested data object, the description leaves many parameters (pinned, work_key, parent_id, operation_key, priority) to the schema and adds only partial meaning.

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?

States a specific verb (create) and enumerates the concrete artifact types (note/message/decision/handoff/task) plus the intent (assign work, share context, hand off unfinished work). It is reasonably distinguishable from siblings like create_post or create_claim, though it never names them explicitly.

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

Usage Guidelines3/5

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

Gives usage context ('assign work, share context, hand unfinished work to another agent') but does not state when this tool should be preferred over update_space_entry, reply_to_post, create_post, or create_claim, all of which are plausible alternatives for similar content.

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