Details how users can submit patch requests using `pr.pico.sh`
without needing to fork the repository or use `git send-email`.

Also clarifies that the example configuration file generation is
optional.

Add new MCP tool to modify task title and/or description with
automatic ID regeneration. The tool accepts task_id (required) and
optional title/description fields, updating only provided fields while
maintaining existing content for omitted ones.

Includes proper validation, logging, and returns updated task list.
Updates documentation across AGENTS.md and README.md.

Add comprehensive documentation of non-obvious implementation details:
- Clarify task ID generation (8 hex chars from SHA256)
- Document silent duplicate task detection behavior
- Explain atomic update pattern in UpdateTasks method
- Detail task list ordering (sorted by creation time)
- Add helper function patterns for MCP responses
- Include config file search paths and naming
- Add test running and maintenance commands

- Remove unused UpdateGoal method from planning manager
- Add documentation comment for HistoryEnabled config field indicating it's reserved for future use
- Improves code maintainability by eliminating dead code

Replace inefficient bubble sort implementation in formatTaskListWithFilter
with Go's standard library sort.Slice for better performance and readability.

- Improves time complexity from O(n²) to O(n log n)
- Reduces code from 7 lines to 3 lines
- Uses idiomatic Go standard library patterns
- Maintains identical sorting behavior (oldest tasks first)
- Passes all linting and static analysis checks

- Create Validator interface and PlanningValidator implementation
- Add comprehensive validation for all MCP request types
- Separate request parsing from validation logic
- Update all MCP handlers to use centralized validation
- Remove unused parseAndValidate function and validator dependency
- Add comprehensive test suite with 565 test cases covering all validation scenarios
- Improve error messages with consistent format
- Enable configuration-based validation limits

- Add internal/mcp/types.go with request structs for all MCP handlers
- Replace manual JSON parsing with parseAndValidate generic helper
- Add go-playground/validator/v10 dependency for struct validation
- Refactor all 6 MCP handlers to use structured types
- Improve type safety and eliminate ~150 lines of manual validation code
- Add compile-time type checking for all MCP request parameters

- Add createErrorResult() and createSuccessResult() helper functions to reduce code duplication
- Add formatGoalText() helper for consistent goal text formatting
- Refactor all MCP handler functions to use helpers instead of inline response creation
- Reduces codebase by ~150 lines (23% reduction in server.go) while improving maintainability
- Provides single point of change for response format modifications
- Ensures consistent error message formatting across all handlers

This adds the initial configuration for the Crush agent,
specifically setting up the Go language server protocol (LSP) via gopls.

- Rename all tools with project_management__ prefix for consistency
- Split goal management into set_goal and change_goal operations
- Add status filtering to get_tasks with enum support (all, pending, in_progress, completed, cancelled, failed)
- Rename update_tasks to update_task_statuses for clarity
- Add StatusCancelled to TaskStatus enum with u2297 indicator
- Update tool descriptions with explicit guidance on usage patterns
- Enhance goal methods to accept title and description separately
- Update AGENTS.md documentation to reflect new tool signatures
- Add .gitignore file to exclude .crush directory

BREAKING CHANGE: All MCP tool names now use project_management__ prefix

Add new MCP tool to delete one or more tasks by their IDs and return
the updated task list. Includes atomic validation to ensure all task
IDs exist before deleting any tasks.

- Replace single task update with batch task update functionality
- Add UpdateTasks method to planning manager for multiple task updates
- Update MCP tool definition to accept array of task updates
- Support both single and multiple task updates in one call
- Update documentation to reflect new update_tasks tool

- Remove JSON examples and technical implementation details
- Focus on capabilities this provides to AI assistants
- Emphasize user benefits over technical specs
- Reorganize content around "What This Gives Your AI Assistant"

- Show verbose instructions + task list when no existing tasks
- Show brief task list output when tasks already exist
- Extract shared formatting logic into reusable formatTaskList method
- Update documentation to reflect new behavior

Strengthen tool descriptions to encourage better planning practices:
- Add explicit guidance to break tasks into smallest units of work
- Encourage frequent task status checks and updates
- Emphasize progress tracking throughout the planning workflow
