Progress Tracking
This skill provides comprehensive guidance on managing tasks/progress.txt files, including format, structure, learnings documentation, and Codebase Patterns management.
Overview
The tasks/progress.txt file serves as:
- A log of completed work across tasks
- A repository of reusable patterns and learnings
- A reference for codebase-specific best practices
- A guardrail system for common pitfalls
Reading Progress Files
Essential Reading Workflow
When starting a task, always read tasks/progress.txt to understand:
- Previous work completed on this and other tasks
- Codebase patterns and learnings from previous iterations
- The Codebase Patterns section (at the top) contains reusable patterns and guardrails
- Task-specific entries show what was done in previous iterations
Codebase Patterns Section
CRITICAL: Check the "Codebase Patterns" section first when reading tasks/progress.txt:
- Reusable patterns discovered in previous work
- Common gotchas and how to avoid them
- Best practices specific to this codebase
- Guardrails and constraints
This section is maintained at the top of the file and contains patterns that apply across all tasks.
Progress.txt Format
Update Requirements
Update progress.txt incrementally:
- After major milestones
- When patterns are discovered
- Before task completion
Document Learnings
Use "Learnings for future iterations:" section:
- Include codebase patterns discovered
- Document successful approaches
- Note common pitfalls
- Capture reusable insights
Success Criteria Validation
Explicitly verify each success criterion:
- Document verification method used
- Update progress before completion marker
- Include evidence of completion
Progress file update (appending to tasks/progress.txt)
When appending a new task block to tasks/progress.txt:
- Read the last 10–20 lines to get exact trailing content and structure.
- Use a unique anchor for search_replace (e.g. task ID and date:
## YYYY-MM-DD - Task TASK_ID). Do not replace on generic separators like --- alone.
- After two failed replace attempts, switch to shell append:
echo '...' >> tasks/progress.txt instead of further edits.
- Optionally: reuse recent grep results when the query is unchanged to avoid redundant searches.
Entry Format
When you complete work or learn something, append to tasks/progress.txt:
## [Date/Time] - Task {id}
- What was implemented
- Files changed
- **Learnings for future iterations:**
- Pattern discovered
- Gotcha encountered
- Useful context
---
Codebase Patterns Management
Adding to Codebase Patterns
If you discover a reusable pattern that should be available for all future tasks, add it to the "Codebase Patterns" section at the top of the file.
When to add:
- Pattern is reusable across multiple tasks
- Pattern prevents common errors
- Pattern represents a codebase-specific best practice
- Pattern documents a constraint or guardrail
Format for Codebase Patterns:
# Codebase Patterns
## Pattern Name
- Description of pattern
- When to use it
- Example usage
- Common pitfalls to avoid
Maintaining Codebase Patterns
- Keep patterns concise and actionable
- Update patterns when they evolve
- Remove outdated patterns
- Group related patterns together
Progress Documentation Best Practices
When to Document
- After major milestones: Document significant progress
- When patterns are discovered: Capture reusable insights
- Before task completion: Ensure all learnings are recorded
- When encountering issues: Document problems and solutions
What to Document
- Implementation details: What was built and how
- Files changed: Track which files were modified
- Learnings: Patterns, gotchas, and useful context
- Verification: How success criteria were validated
Progress Update Checklist
Before completing a task, verify:
- ✅ Major milestones documented
- ✅ Learnings captured in "Learnings for future iterations:" section
- ✅ Codebase patterns added if applicable
- ✅ Success criteria validation documented
- ✅ Files changed are listed
- ✅ Verification method is recorded
Integration with Other Skills
This skill works with:
- task-verification-workflow: Document verification methods
- error-recovery-patterns: Document error handling learnings
- completion-marker-optimization: Update progress before completion marker
Examples
Example Entry
## 2026-01-27 14:30 - Task 42
- Implemented user authentication flow
- Files changed: src/auth.ts, src/components/Login.tsx
- **Learnings for future iterations:**
- Use JWT tokens stored in httpOnly cookies for security
- Always validate tokens server-side before processing requests
- Pattern: Authentication middleware should check token expiry
---
Example Codebase Pattern
# Codebase Patterns
## Authentication Pattern
- Always use httpOnly cookies for JWT tokens
- Validate tokens server-side in middleware
- Check token expiry before processing requests
- Never expose tokens in client-side JavaScript
