gitchanger_mcp_set

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

No annotations are supplied, so the description carries the full behavioral burden for a tool that writes a credential. It does not disclose whether an existing token is overwritten, where the token is persisted, whether the token is validated before storage, or any security/permission implications of storing a plaintext PAT.

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?

A single compact sentence with the key resource front-loaded and no filler. It is arguably too terse for a credential-writing tool, but nothing in it is wasted.

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?

With five parameters, no annotations, and no output schema, the definition is minimally adequate: the agent knows the intent but not the side effects on existing configuration or the overwrite semantics. For a mutation tool touching credentials, that leaves meaningful gaps.

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 coverage is 100%, so all five parameters are already documented in the schema. The description adds a little meaning by mapping profile vs. direct to two distinct outcomes, which helps the agent understand they are mutually exclusive paths, but it adds no detail on token format, the 'file' override, or sync interaction beyond the schema.

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?

States a specific verb (Set) and resource (GitHub MCP Personal Access Token) and names the two target modes: a profile or directly into MCP client configs. This clearly separates it from siblings like gitchanger_mcp_get or gitchanger_mcp_remove, though it does not explicitly contrast with gitchanger_mcp_sync, which also writes tokens to client configs.

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 two modes (profile-scoped vs. direct) are implied by the phrase 'for a profile or directly into MCP client configs,' but the agent gets no explicit guidance on when to use each, whether a profile must already exist, or when to prefer gitchanger_mcp_sync afterward.

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