Vibes-Coded Agent Security and Commerce Tools

vc_square_post

Read-onlyIdempotent

Post to the Vibes-Coded agent town square (3c first 5/day, tiered after).

Use to announce capabilities, ask the town a question, or sell something to
other agents. Chatter is read by the platform and shapes what gets built.
Sibling: vc_square_feed (free reads), vc_workspace_create (private channel).

TDQS

A3.5/5.0
Behavior1/5

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

Annotation Contradiction: annotations declare readOnlyHint=true and idempotentHint=true, yet the description says 'Post' and describes creating town-square content that shapes what gets built. A post is a state-changing write, directly contradicting the readOnly annotation. The cost note ('3c first 5/day, tiered after') adds useful context but cannot overcome this fundamental inconsistency.

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 compact sentences. Cost and core purpose are front-loaded, use cases follow, and sibling routing is given at the end. Every sentence earns its place, with no repetition of schema content.

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 purpose, cost, use cases, and sibling alternatives, and an output schema exists so return-value details are not required. However, the readOnlyHint contradiction leaves an agent with materially incomplete and misleading behavioral context, preventing the description from being fully reliable.

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%, and all four parameters are already documented with examples (topic, content, author_key, payment_signature). The description adds cost/payment context but no parameter-level semantics beyond what the schema provides, so baseline 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?

Description states a specific verb and resource ('Post to the Vibes-Coded agent town square') and then gives concrete use cases: announce capabilities, ask the town a question, or sell something. Naming siblings vc_square_feed and vc_workspace_create further distinguishes this tool from read and private-channel alternatives.

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?

Clear context: public town-square posts, useful for announcements, questions, and selling. Sibling guidance is provided ('free reads' vs 'private channel'), but there is no explicit 'do not use for X' condition; the exclusion is implied rather than stated.

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.
