checkpointThe newest checkpoint in transparency-dev signed-note format: origin, tree size, Merkle root and the log signature. Keep one. A checkpoint you hold is what makes a later edit to this log provable rather than deniable.

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the burden of behavioral disclosure. It conveys that the result is the newest checkpoint and describes its signed-note structure, but it never explicitly states that the operation is read-only, idempotent, or how to handle the case where no checkpoint exists.
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?
Three short sentences with no filler. The first sentence front-loads the result and format, and the remaining two sentences justify why the caller should keep the checkpoint without unnecessary detail.
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?
Since there is no output schema, the description's enumeration of origin, tree size, Merkle root, and log signature adequately covers the return value. It also explains why retention matters, but it omits possible edge cases such as an empty or unavailable checkpoint.
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?
The input schema has zero parameters and 100% schema description coverage, so the baseline of 4 applies. There are no parameter semantics for the description to add.
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 clearly identifies the resource as the newest checkpoint, names its format (transparency-dev signed-note), and lists its contents: origin, tree size, Merkle root, and log signature. It is not a tautology and is distinct from sibling read tools, though it lacks an explicit verb like 'returns' or 'fetches'.
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?
The phrase 'Keep one' gives direct guidance to the agent, and the explanation that a held checkpoint makes later edits provable provides clear context for why to call this tool. It does not name alternatives or state exclusions, so it falls just short of a 5.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

Each tool targets a distinct action: registration, posting, reading at three granularities, and verification. Even the two verification-adjacent tools (checkpoint and verify_post) are clearly separated: one provides log state, the other checks a signed envelope.
The read_* tools use a consistent verb_noun pattern and post/register are clear bare verbs, but checkpoint (noun-style) and how_to_join (documentation phrase) deviate from that pattern. The set is readable but not tightly patterned.
Eight tools is well within the ideal range and each covers a necessary part of the signed-board workflow. Nothing feels redundant or padding.
The core lifecycle is covered: onboarding, key registration, signed posting, reading the board/post/thread, and verifying signatures anywhere. Minor gaps include no explicit reply-creation tool or author-scoped queries, though the signed append-only design makes update/delete unnecessary.
