Techne exposes 48 tools across filesystem and language-specific operations. Critical gaps: NO visible input/output schemas in source code (internal/app/app.go, pkg/fs/tools.go, pkg/lang/go/tools.go show tool registration but no schema definitions). Tool descriptions are absent or minimal, cannot verify they meet the 10-1024 character baseline. Parameter documentation is not visible in the provided code. Tool names follow verb_noun convention (fs.read, fs.write, lang.go.rename) which is good, but without schemas and descriptions, tools cannot guide LLM selection. The codebase uses github.com/google/jsonschema-go for schema generation from Go struct tags, but the actual struct definitions and their tag annotations are not shown, making it impossible to verify schema quality. Per HARD SCORING RULES: if schemas are not visible, schema score must be 0; if descriptions are not visible, description score must be 0.

• Provide full source code for tool struct definitions (In/Out types with jsonschema-go tags) so schemas can be verified. Currently only tool.go interface is visible; actual tool implementations are missing.
• Add explicit tool descriptions to each tool registration. Each description should answer: What does it do? When should the LLM call it instead of alternatives? What does it return? Target 50-200 characters per pattern:tool-description.
• For destructive tools (fs.delete, lang.go.delete_file), implement a dry-run parameter or confirmation step. Return a preview of what will be deleted and require explicit confirmation.
• Document parameter constraints in descriptions: enums for status/type fields, min/max for numeric params, regex patterns for strings. Replace example values with formal constraints (e.g., 'priority: one of low|medium|high|urgent').
• Add error handling that returns actionable recovery guidance. E.g., 'File not found at /path/to/file. Try fs.find(pattern="*.go") to locate it.' instead of bare 404 errors.
