# Planning with Files

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

## Where Files Go

- **Templates** are in `skills/planning-with-files/templates/`
- **Your planning files** go in **your project directory**

| Location                                                | What Goes There                               |
| ------------------------------------------------------- | --------------------------------------------- |
| Skill directory (`skills/planning-with-files/`) | SKILL.md and templates            |
| Your project directory                                  | `plan.md`, `findings.md`, `progress.md` |

## Quick Start

Before ANY complex task:

1. **Create `plan.md`** — Use [templates/plan.md](templates/plan.md) as reference
2. **Create `findings.md`** — Use [templates/findings.md](templates/findings.md) as reference
3. **Create `progress.md`** — Use [templates/progress.md](templates/progress.md) as reference
4. **Re-read plan before decisions** — Refreshes goals in attention window
5. **Update after each phase** — Mark complete, log errors

> **Note:** Planning files go in your project root, not the skill installation folder.
## The Core Pattern

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

→ Anything important gets written to disk.
```

## File Purposes

| File            | Purpose                     | When to Update      |
| --------------- | --------------------------- | ------------------- |
| `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 `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.

```markdown
## Errors Encountered
| Error             | Attempt | Resolution             |
| ----------------- | ------- | ---------------------- |
| FileNotFoundError | 1       | Created default config |
| API timeout       | 2       | Added retry logic      |
```

### 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
```

## Read vs Write Decision Matrix

| Situation             | Action                  | Reason                        |
| --------------------- | ----------------------- | ----------------------------- |
| Just wrote a file     | DON'T read              | Content still in context      |
| Viewed image/PDF      | Write findings NOW      | Multimodal → text before lost |
| Browser returned data | Write to file           | Screenshots don't persist     |
| Starting new phase    | Read plan/findings      | Re-orient if context stale    |
| Error occurred        | Read relevant file      | Need current state to fix     |
| Resuming after gap    | Read all planning files | Recover state                 |

## The 5-Question Reboot Test

If you can answer these, your context management is solid:

| Question             | Answer Source                  |
| -------------------- | ------------------------------ |
| Where am I?          | Current phase in plan.md |
| Where am I going?    | Remaining phases               |
| What's the goal?     | Goal statement in plan         |
| What have I learned? | findings.md                    |
| What have I done?    | progress.md                    |

## When to Use This Pattern

**Use for:**
- Multi-step tasks (3+ steps)
- Research tasks
- Building/creating projects
- Tasks spanning many tool calls
- Anything requiring organization

**Skip for:**
- Simple questions
- Single-file edits
- Quick lookups

## Templates

Copy these templates to start:

- [templates/plan.md](templates/plan.md) — Phase tracking
- [templates/findings.md](templates/findings.md) — Research storage
- [templates/progress.md](templates/progress.md) — Session logging

## Anti-Patterns

| Don't                           | Do Instead                      |
| ------------------------------- | ------------------------------- |
| Use TodoWrite for persistence   | Create `plan.md` file     |
| 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 |
| Create files in skill directory | Create files in your project    |
