Planning with Files Skill

Planning with Files

Work like Manus: Use persistent markdown files as your "working memory on disk."

Core Principle

Context Window = RAM (volatile, limited)
Filesystem = Disk (persistent, unlimited)

→ Anything important gets written to disk.

Quick Start

Before ANY complex task, create these three files:

task_plan.md — Track phases and progress
findings.md — Store research and discoveries
progress.md — Session log and test results

See references/ for starting templates.

File Purposes

| File | Purpose | When to Update | |------|---------|----------------| | task_plan.md | Phases, progress, decisions | After each phase | | findings.md | Research, discoveries | After ANY discovery | | progress.md | Session log, test results | Throughout session |

Critical Rules

1. Create Plan First

Never start a complex task without task_plan.md. Non-negotiable.

2. The 2-Action Rule

"After every 2 view/browser/search operations, IMMEDIATELY save key findings to text files."

This prevents visual/multimodal information from being lost.

3. Read Before Decide

Before major decisions, read the plan file. This keeps goals in your attention window.

4. Update After Act

After completing any phase:

Mark phase status: in_progress → complete
Log any errors encountered
Note files created/modified

5. Log ALL Errors

Every error goes in the plan file. This builds knowledge and prevents repetition.

6. Never Repeat Failures

if action_failed:
    next_action != same_action

Track what you tried. Mutate the approach.

The 3-Strike Error Protocol

ATTEMPT 1: Diagnose & Fix
  → Read error carefully
  → Identify root cause
  → Apply targeted fix

ATTEMPT 2: Alternative Approach
  → Same error? Try different method
  → Different tool? Different library?
  → NEVER repeat exact same failing action

ATTEMPT 3: Broader Rethink
  → Question assumptions
  → Search for solutions
  → Consider updating the plan

AFTER 3 FAILURES: Escalate to User
  → Explain what you tried
  → Share the specific error
  → Ask for guidance

When to Use This Pattern

Use for:

Multi-step tasks (3+ steps)
Research tasks
Building/creating projects
Tasks spanning many tool calls

Skip for:

Simple questions
Single-file edits
Quick lookups

Templates

references/task_plan.md — Phase tracking template
references/findings.md — Research storage template
references/progress.md — Session logging template

Advanced Topics

Manus Principles: See references.md for complete context engineering patterns
Real Examples: See examples.md for practical implementations

Anti-Patterns

| Don't | Do Instead | |-------|------------| | State goals once and forget | Re-read plan before decisions | | Hide errors and retry silently | Log errors to plan file | | Stuff everything in context | Store large content in files | | Start executing immediately | Create plan file FIRST | | Repeat failed actions | Track attempts, mutate approach |

This pattern is why Manus went from launch to $2B acquisition in 8 months.
