rynmesh_record_credit_event

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

With no annotations, the description carries the full burden, and it only discloses that the operation appends and that the event is 'signed'. It does not disclose that appending is effectively irreversible ledger mutation, whether signing requires registration/auth, what side effects occur on the credit ledger, or that dedupe_key implies idempotency behavior.

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

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

The single 13-word sentence is tight and front-loaded, putting the core action ('Append a signed Rynmesh Credit event') first with zero filler. It loses a point because the extreme brevity leaves no room for structured guidance about the two event uses, though that is more a completeness issue than a conciseness one.

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

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

For a 10-parameter mutation tool with no annotations, no output schema, and nested objects, the description is far from adequate: it omits return behavior, deduplication semantics, signing/auth requirements, and the meaning of most fields. An agent cannot reliably construct a valid call from this definition alone.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 0% across 10 parameters, and the description adds almost no parameter-level meaning — it hints at two event flavors ('useful work or protocol penalties') but never maps them to 'kind' or any other field. Confusing pairs like subject_id vs subject_peer_id, the units of amount, the purpose of dedupe_key, and the shape of metadata are entirely undocumented in both schema and description.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description states a specific verb and resource ('Append a signed Rynmesh Credit event') plus a clear purpose ('for useful work or protocol penalties'), which distinguishes it from the read-only credit siblings (rynmesh_credit_summary, rynmesh_credit_scoreboard). It stops short of 5 because the domain term 'Credit event' and the meaning of 'kind' are left unexplained, so an agent must infer the event taxonomy.

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

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

There is no guidance on when to record an event versus when to read credits, nor any conditions, prerequisites, or exclusions. With 38 siblings including credit_summary and credit_scoreboard, the description does nothing to route the agent toward or away from alternatives.

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