Configure the git credential helper to use a specific vault path. Returns new credential helper value.
| Name | Required | Description | Default |
|---|---|---|---|
| vaultPath | No | Path to the credential helper vault executable. | |
| workingDirectory | No | Git repo path. Default current directory. | . |
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Without annotations, the description should disclose behavioral traits. It mentions returning a new credential helper value but does not explain side effects, permissions needed, or whether the operation is destructive. This is insufficient for safe invocation.
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?
The description is two sentences with no extraneous words. Every part earns its place, stating the action and the return value efficiently.
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?
The description specifies the return value, which is good given no output schema. However, it lacks context on prerequisites, validation, or idempotency. For a configuration-modifying tool, this is minimally complete.
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 the schema already describes both parameters fully. The description adds no new meaning beyond paraphrasing the vaultPath parameter; workingDirectory is omitted. A score of 3 is appropriate for meeting baseline but not exceeding it.
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 states the tool configures the git credential helper to use a specific vault path, which is a specific verb+resource. It distinguishes from sibling tools like set_ssh and set_token by focusing on vault path configuration.
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?
No guidance is provided on when to use this tool versus alternatives like set_ssh or get_vault_status. The agent must infer usage from the name and description alone.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Add one secure layer between your agents and this server.
Each tool has a clearly distinct purpose. Even similar tools like 'undo_changes' and 'restore_file' differ in scope (all vs single file), and 'find_changes' vs 'show_change' list files vs show diffs. No two tools overlap ambiguously.
All tool names follow a verb_noun snake_case pattern. While verbs are not perfectly uniform (e.g., 'get_vault_status' vs 'show_history'), the naming is consistent and predictable, with no mixed camelCase or confusing conventions.
22 tools is on the higher side but appropriate for a comprehensive Git server covering branch management, commits, pushes, credentials, diagnostics, and more. The number is manageable and each tool serves a distinct function.
The tool set covers essential operations but has notable gaps: there's no branch listing, pull/merge, or stash functionality. Agents may encounter dead ends when needing these operations, though core workflows like commit and push are well supported.
