GHE: Repo Summary

ghe_repo_summary
Read-only

Summary of a repository: default branch, latest commit, open PRs count, branch count, etc. repo accepts "name" or full slug "owner/name" (github.com or GHE).

Input Schema

NameRequiredDescriptionDefault
repoYesRepository name or full owner/name slug. Prefer owner/name when known so routing never depends on a workspace default.
ownerNoOptional GitHub org/user. A full repo slug (owner/name) takes precedence; otherwise the active workspace default org is used.
context_idNoOptional explicit Connection Hub work context (ctx_*). Omit to use the conversation's active workspace; global Hub tools ignore it.

Output Schema

NameRequiredDescriptionDefault
okYes
dataYes
contractVersionYes
dataSchemaVersionYes

  2. First observed

TDQS

A3.6/5.0
Behavior3/5

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

Annotations already declare readOnlyHint=true and openWorldHint=false, so safety is covered and the bar is lower. The description adds what data the summary contains, but says nothing about return format beyond field names or any rate/scope caveats, so it adds only modest value.

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?

Two tight sentences, front-loaded with the summary contents followed by the repo format note. Zero filler.

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

Completeness4/5

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

A read-only summary tool with a fully documented schema and an existing output schema needs little prose; the description conveys purpose and scope adequately. Slightly more guidance on how it relates to sibling listing tools would make it complete.

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 coverage is 100%, so all three parameters are fully documented in the schema. The description restates that repo accepts 'name' or 'owner/name' slug, which is already in the repo parameter description, adding no meaning beyond the schema. Baseline 3 applies.

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

Purpose4/5

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

States a specific resource (repository summary) and enumerates the aggregated fields returned (default branch, latest commit, PR/branch counts). This differentiates it from granular siblings like ghe_branches_list or ghe_commits_list, though it doesn't name them explicitly.

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

Usage Guidelines3/5

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

The aggregated nature implies 'use this for a quick overview,' but there is no explicit when-to-use versus when-to-use-siblings guidance or exclusions. Usage is inferred rather than stated.

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