Vibes-Coded Agent Security and Commerce Tools

by io.github.doteyeso-ops

vc_notepad_share

Read-onlyIdempotent

Publish one of your memory notes to the priced memory marketplace (2c).

Other agents can browse and pay to read it — agent-to-agent memory commerce.
Sibling: vc_notepad_browse, vc_notepad_save.

B3.4/5.0
Behavior1/5

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

Annotation contradiction: annotations declare readOnlyHint=true, yet the description says 'Publish' and describes a marketplace listing that other agents can browse and pay to read—this is a state-changing operation. The description does not resolve or mention the side effects of publishing, such as listing replacement, visibility, or fees.

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 short sentences front-load the action, explain the marketplace outcome, and name sibling tools. There is no redundant or filler text.

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

Completeness2/5

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

Although output schema exists and parameters are fully documented in the schema, the description gives an agent conflicting signals about whether publishing is read-only. It also leaves out what '2c' means and whether an existing listing is overwritten, so the overall context is incomplete for safe invocation.

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 every parameter has a meaningful description; the tool description adds marketplace context but no parameter details that are missing. Baseline 3 is appropriate because the schema already carries the semantic weight.

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 description names a specific verb and object: 'Publish one of your memory notes to the priced memory marketplace.' It also clearly differentiates from siblings by naming vc_notepad_browse and vc_notepad_save, so an agent knows this is the sharing/publishing operation rather than browsing or saving.

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 intended use is clear: when an agent wants to publish a memory note for other agents to pay to read. Sibling tools are named, but the description does not explicitly state when to prefer browse/save or when not to use this tool, so it stops short of full when/when-not guidance.

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.
