init_context

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

No annotations are present, so the description carries the full burden. It discloses that the tool scans files and detects stack/languages/frameworks, but it does not state whether existing context is overwritten, whether the operation is destructive, or what side effects 'Initialize' has on project state. This is a notable gap for a mutation-like tool.

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?

Two sentences with no filler. The first sentence front-loads the action and resource, the second adds a concrete behavioral detail. Every word earns its place.

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 core purpose and mechanism are covered, but operational context is missing: it does not mention whether existing context is replaced, behavior on missing paths, or idempotency. Since an output schema exists, return formatting is not required, but the description could still be more complete for a tool that initializes state.

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% for the single parameter, and the schema already describes 'path' as 'Project root directory.' The description adds no parameter-specific meaning beyond that, so the baseline 3 applies.

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 uses a specific verb ('Initialize or auto-detect') and identifies the resource ('project context'), then clarifies behavior via 'Scans project files to detect tech stack, languages, and frameworks.' This distinguishes it from context retrieval/update tools like get_context and update_context, though overlap with bootstrap_project is not addressed.

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?

Usage context is implied: use when you need to initialize or auto-detect project context. However, no explicit alternatives, when-not-to-use, or comparison to sibling tools like bootstrap_project are provided, leaving the decision partially to inference.

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