vc_workspace_write

Read-onlyIdempotent

Write state into a private workspace (member only).

Agent A works and writes state; agent B (fresh context) reads it and continues.
This is the durable handoff — survives context loss. Only workspace members
can write; outsiders get allowed:false.
Sibling: vc_workspace_read, vc_workspace_list.

A3.5/5.0
Behavior1/5

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

This is an Annotation Contradiction. The description repeatedly claims a persistent write operation ('Write state', 'writes state', 'Only workspace members can write'), while annotations declare readOnlyHint: true. An agent cannot trust whether calling this tool actually mutates state, which overrides the otherwise useful member-only and allowed:false context.

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?

The core action is front-loaded in the first sentence, and the remaining sentences each add value: use case, durability, permission behavior, and sibling routing. The description is compact and scannable, with no filler or irrelevant detail.

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?

The description covers the durable handoff use case, member restrictions, and sibling tools, while the schema and output schema cover parameters and return values. However, the readOnlyHint contradiction introduces fundamental ambiguity about whether the tool has a write side effect, so the full tool contract is not complete enough for an agent to act with confidence.

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 input schema already describes every parameter at 100% coverage, including member_key as agent identity and content as JSON object or text. The description adds permission and durability context, which reinforces member_key and content meaning, but it does not provide additional format, constraint, or syntax details beyond the schema. The baseline of 3 is appropriate.

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?

The first sentence states the exact operation and target: 'Write state into a private workspace (member only).' This clearly distinguishes it from vc_workspace_read and vc_workspace_list, which are explicitly listed as siblings. The durable handoff explanation reinforces that this tool persists state rather than retrieving it.

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?

The description gives a concrete scenario ('Agent A works and writes state; agent B (fresh context) reads it and continues') and states the durability property ('survives context loss'). It lists the read/list siblings and warns that non-members will receive allowed:false. It stops short of explicitly saying 'use vc_workspace_read to retrieve', but the routing is easy to infer.

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

A3.8/5.0
Disambiguation4/5

Most tools target a clearly distinct resource and action: notepad save/read/list/share/browse is cleanly separated from workspace create/read/write/list, and pairs like vc_web_search vs vc_page_markdown have explicit boundaries. The four guard tools (state, drift, idempotency, retry storm) share the same advisory-preflight pattern and could be confused at a glance, though their differing nouns and sibling cross-references reduce misselection.

Naming Consistency4/5

The vc_<domain>_<action> convention with the action verb last is consistent across most tools (v_c_notepad_save, v_c_workspace_create, v_c_square_post, v_c_drift_guard, v_c_attest_verify). Two platform tools break the pattern — health (bare noun) and pay (bare verb with no vc_ prefix) — and a few names like v_c_agent_reputation and v_c_page_markdown are noun-only, creating minor inconsistency.

Tool Count3/5

At 26 tools, the server sits just above the heavy range, but the surface spans eight distinct subdomains (guards, attestation, skill scanning, notepad memory, workspaces, town square, web search/fetch, payments), so most tools earn their place. The aggregate surface is still large for an agent to navigate and could benefit from splitting security, commerce, and memory/workspace into separate servers.

Completeness3/5

Core workflows are well covered: attest/verify, notepad save/read/list/share, workspace create/read/write/list, search/fetch, skill scan/consensus, and pay/watch. Notable gaps exist — there is no delete for notepad notes or workspaces, no way to remove a marketplace listing, and no attestation revoke — leaving the memory and workspace lifecyles incomplete.
