github_create_issue_comment

DestructiveIdempotent

Post a comment to a GitHub issue via project-scoped connector, with verified write effect and idempotency support for reliable automation.

Instructions

Github connector operation create_issue_comment (platform tool github.create_issue_comment).

Routes only through the exact project/account governed connector authority.

Args: arguments: JSON string of arguments for the connector operation. project_id: Authenticated Project UUID. project_ref: Exact project correlation reference. connector_account_ref: Project-bound connector account alias. idempotency_key: Stable business-action identity. effect: Claimed read or write effect; Spring verifies it. approval_ref: Approved platform task UUID when resuming a write.

TDQS

C2.8/5.0
Behavior4/5

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

Annotations already mark this as non-read-only, idempotent, and destructive. The description adds genuinely useful behavioral context: it routes only through the governed project/account connector, the claimed effect is verified by Spring, and approval_ref is used when resuming a write. This gives the agent a much clearer picture of the guardrails around invocation without contradicting the annotations.

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 compact, uses a clear argument list, and front-loads the connector operation and routing constraint. It could be slightly tighter because the first sentence largely repeats the tool name, but overall it is efficiently organized.

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?

Despite 7 parameters and output-schema presence, an agent cannot tell from this description what the arguments JSON must contain, what the actual GitHub side effect is, or when this tool is the right sibling to use. The governance parameters are documented, but the domain operation semantics are missing, leaving the description incomplete for correct 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?

With schema description coverage at 0%, the description must supply parameter meaning, and it does for the wrapper parameters (project_id, effect, approval_ref, idempotency_key, etc.). However, the most important parameter, arguments, is only described as a 'JSON string of arguments for the connector operation' and never explains what fields the GitHub create-issue-comment operation requires (e.g., issue number/identifier and comment body). The compensation is therefore partial.

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

Purpose2/5

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

The description opens by restating the tool's name ('Github connector operation `create_issue_comment`') and never explains in its own words that this tool creates a comment on a GitHub issue. The routing sentence is a constraint, not a statement of function, so an agent would have to infer purpose from the name alone.

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

Usage Guidelines2/5

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

There is no guidance about when to choose this tool over sibling GitHub tools (e.g., github_create_issue, github_create_pull_request) or when a different mechanism is preferable. The only usage-related content, the governed-connector routing constraint, is a technical restriction rather than a selection guide.

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