deployer_reputation

Read-onlyIdempotent

Score Solana launch records by grouping deployers and funders, then rank clusters with explainable 0-1 heuristic components and label-coverage evidence to assess deployer reputation.

Instructions

Score funding-association groups in supplied Solana launch records with explainable 0-1 heuristic components and label-coverage evidence. Use after your pipeline resolves deployer, pre-launch funder and mint; choose cluster_launches for membership only. Not for wallet/token lookup, prediction, ownership attribution or safety decisions; scores are not probabilities and low does not mean safe. Supply 1-1000 distinct-mint edges. Keep connected groups together: splitting batches changes results. A funder_is_cex flag anywhere prevents that funder joining distinct deployers; it does not separate the same deployer's launches. lamports and block_time are validated but do not affect scores; cadence measures launch count, not time. Stateless local computation: no network/RPC, label verification, storage writes, credentials or external side effects. Each full stdio request line is limited to 512000 bytes. Returns score-sorted clusters, membership, components, evidence, counts and versions. Check labelCoverage and notes: rug-rate evidence is null without labels, not zero. Invalid input rejects the whole batch with isError=true; correct it and retry.

A4.8/5.0

Behavior5/5

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

The annotations already indicate readOnly, idempotent, and non-destructive behavior, and the description goes well beyond them by disclosing stateless local computation, absence of network/RPC or storage writes, and the fact that invalid input rejects the whole batch. It also warns that scores are not probabilities and that low scores do not mean safe, which is crucial behavioral context for an AI agent. No contradiction with annotations exists.

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?

The description is longer than typical but every sentence earns its place: purpose, exclusions, input constraints, grouping semantics, statelessness, output contents, and error behavior are all covered. It is packed but not rambling; a bulleted structure would improve scannability, but the front-loaded purpose and tight prose keep it well-organized.

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

Completeness5/5

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

For a complex scoring tool with an output schema, the description covers all critical invocation context: input shape and limits, grouping sensitivity, validation semantics, stateless behavior, batch size limit, return contents, and retry behavior on invalid input. The presence of an output schema means return-value details need not be repeated, and the description still summarizes what the output contains.

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

Parameters4/5

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

The input schema already has 100% coverage, so the baseline is 3, but the description adds meaningful operational nuance: edge count limits, the requirement to keep connected groups together, the cross-batch effect of funder_is_cex, and the fact that lamports/block_time are validated but do not affect scoring. This goes beyond schema documentation, though the schema still carries most of the parameter burden.

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 opens with a specific verb and resource ('Score funding-association groups in supplied Solana launch records') and clearly names the deliverable ('explainable 0-1 heuristic components and label-coverage evidence'). It also distinguishes itself from sibling cluster_launches by noting that membership-only grouping belongs to that sibling. This gives an agent a precise mental model of the tool's function.

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

Usage Guidelines5/5

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

The description is explicit about when to use the tool ('Use after your pipeline resolves deployer, pre-launch funder and mint') and when not to use it ('Not for wallet/token lookup, prediction, ownership attribution or safety decisions'). It even names the sibling alternative for membership-only needs. This is strong routing guidance with no ambiguity.

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