# Remove All Content Truncation in Toolsets

## Problem Summary

While IDs are no longer truncated, content, descriptions, titles, and other text fields are still being truncated with patterns like `[:80]`, `[:100]`, `[:150]`, `[:200]` throughout toolsets. Agents need full information to make proper decisions, not truncated previews.

## Scope

Remove truncation from:

1. **Tool output messages** - Content shown in `read_*` functions
2. **Storage status summaries** - `get_status_summary()` methods
3. **Linking descriptions** - `get_outputs_for_linking()` methods
4. **Any other agent-facing output**

## Files Requiring Changes

### Category 1: Toolset Tool Files (Tool Output Messages)

These show truncated content in `read_*` functions that agents call:

## Implementation Pattern

**Simple replacement pattern:**

```python
# Before - Truncated content
f"Content: {item.content[:100]}..." if len(item.content) > 100 else f"Content: {item.content}"
f"      {c.content[:80]}{'...' if len(c.content) > 80 else ''}"

# After - Full content
f"Content: {item.content}"
f"      {c.content}"
```

**For conditional truncation patterns:**

```python
# Before
description = f"Todo: {todo.content[:100]}..." if len(todo.content) > 100 else f"Todo: {todo.content}"

# After
description = f"Todo: {todo.content}"
```

**For list limiting patterns:**

```python
# Before - Limited items
for item in items[:5]:
    lines.append(f"  {item}")
if len(items) > 5:
    lines.append(f"  ... +{len(items) - 5} more")

# After - Show ALL items
for item in items:
    lines.append(f"  {item}")
# Remove "more" message entirely
```

**For error message lists:**

```python
# Before - Limited available items
available = ", ".join([item.id for item in list(items.values())[:5]])
return f"Error: Item not found. Available: [{available}]."

# After - Show ALL available items (or at least many more)
available = ", ".join([item.id for item in items.values()])
# Or if list is very long, show more but still indicate completeness
available = ", ".join([item.id for item in list(items.values())[:20]])
return f"Error: Item not found. Available ({len(items)} total): [{available}]."
```

### Category 3: List Limiting in Read Functions (CRITICAL - Show ALL Items)

**REQUIREMENT**: All `read_*` functions MUST show ALL items - no limits. Agents need complete state visibility to avoid misbehavior.

20. **[beam_search_reasoning/toolset.py](pydantic_ai_toolsets/toolsets/beam_search_reasoning/toolset.py)**

    - Line 253: `candidates[:5]` → Remove limit, show ALL candidates
    - Line 260: `... +{len(candidates) - 5} more` → Remove this truncation message
    - Line 518: `scored_list[:3]` → Show all scored candidates in system prompt

21. **[multi_persona_debate/toolset.py](pydantic_ai_toolsets/toolsets/multi_persona_debate/toolset.py)**

    - Line 568: `critique.specific_points[:3]` → Show ALL points (remove limit)
    - Line 600: `agreement.reasoning[:3]` → Show ALL reasoning (remove limit)

22. **[graph_of_thought_reasoning/toolset.py](pydantic_ai_toolsets/toolsets/graph_of_thought_reasoning/toolset.py)**

    - Line 283: `evaluations[:5]` → Show ALL evaluations (remove limit)
    - Line 286: `... +{len(_storage.evaluations) - 5} more` → Remove truncation message
    - Line 579: `evaluated[:3]` → Show all evaluated nodes in system prompt

23. **[tree_of_thought_reasoning/toolset.py](pydantic_ai_toolsets/toolsets/tree_of_thought_reasoning/toolset.py)**

    - Line 465: `storage.evaluations.items()[:5]` → Show ALL evaluations (remove limit)
    - Line 468: `... and {len(storage.evaluations) - 5} more` → Remove truncation message

24. **[monte_carlo_reasoning/toolset.py](pydantic_ai_toolsets/toolsets/monte_carlo_reasoning/toolset.py)**

    - Line 558: `children[:3]` → Show ALL children in system prompt (remove limit)

25. **[self_ask/toolset.py](pydantic_ai_toolsets/toolsets/self_ask/toolset.py)**

    - Line 396: `final_answer.composed_from_answers[:5]` → Show ALL answer IDs (remove limit)
    - Line 398: `... and {len(final_answer.composed_from_answers) - 5} more` → Remove truncation message

26. **[beam_search_reasoning/toolset.py](pydantic_ai_toolsets/toolsets/beam_search_reasoning/toolset.py)**

    - Line 307: `list(_storage.nodes.values())[:5]` in error messages → Show all (or at least more)
    - Line 326: `list(_storage.candidates.values())[:5]` in error messages → Show all available
    - Line 377: `list(_storage.candidates.values())[:5]` in error messages → Show all available
    - Line 399: `_storage.steps[:5]` → Show all steps

**Pattern to fix:**

```python
# Before - Limited items
for c in candidates[:5]:
    # show candidate
if len(candidates) > 5:
    lines.append(f"... +{len(candidates) - 5} more")

# After - Show ALL items
for c in candidates:
    # show candidate
# Remove "more" message entirely
```

### Category 4: Evaluation Code Truncation

Evaluation code also truncates content, which affects debugging and result accuracy:

26. **[evals/base.py](pydantic_ai_toolsets/evals/base.py)**

    - Line 452: `prompt[:50] `→ `prompt` (case_name in EvaluationResult)

27. **[evals/categories/combinations/compare_combinations.py](pydantic_ai_toolsets/evals/categories/combinations/compare_combinations.py)**

    - Line 66: `error_message[:500] `→ `error_message`
    - Line 75: `error_message[:500] `→ `error_message`

**Note**: While evaluation code isn't directly agent-facing, truncation here affects debugging and test result accuracy.

### Category 5: Storage List Limiting (CRITICAL - Show ALL Items)

Storage status summaries limit lists - agents need to see ALL items:

28. **[multi_persona_debate/storage.py](pydantic_ai_toolsets/toolsets/multi_persona_debate/storage.py)**

    - Line 419: `list(self._personas.values())[:3]` → Show ALL personas (remove limit)
    - Line 421: `... and {len(self._personas) - 3} more` → Remove truncation message

29. **[multi_persona_analysis/storage.py](pydantic_ai_toolsets/toolsets/multi_persona_analysis/storage.py)**

    - Line 328: `list(self._personas.values())[:3]` → Show ALL personas (remove limit)
    - Line 330: `... and {len(self._personas) - 3} more` → Remove truncation message

30. **Error Message List Limits** (Throughout toolsets)

    - Many error messages show `[:5]` items in "Available" lists
    - These should show ALL available items, or at least significantly more (e.g., `[:20]` or all)
    - Files affected: All toolset files with error messages showing available items

## Critical Requirements

- **NO LIMITS**: Show ALL items always - no `[:N]` limits on lists
- **NO TRUNCATION**: Show full content always - no `[:N]` on content/text
- **NO "MORE" MESSAGES**: Remove all `... +N more` truncation indicators
- **Complete State Visibility**: Agents must see complete state to avoid misbehavior

## Notes

- **List limiting MUST be removed**: Agents need to see ALL items, not just first N. This is critical for proper decision-making.

- **Error message limits**: Even error messages showing "Available" items should show ALL items (or at least many more than 5) so agents can see complete options.

- **Metrics/input_text truncation**: Some truncation in metrics tracking (e.g., `merged_content[:50]` for input_text) should also be removed for consistency, but these are less critical since they're not agent-facing.

- **No exceptions**: Remove ALL truncation and limits - agents need complete information. If content is too long or there are many items, that's acceptable - agents can handle it.

- **Storage linking descriptions**: These are used when agents create cross-toolset links, so they need full content for proper context.

- **Status summaries**: These appear in tool outputs and system prompts, so agents see them directly.

- **Evaluation code**: While not directly agent-facing, truncation here affects debugging and should be removed for consistency.

## Testing Considerations

After changes, verify:

1. Tool outputs show full content (no `...` truncation markers)
2. Storage summaries show full content
3. Linking descriptions contain full content
4. No regressions in functionality

## Comprehensive Verification Strategy

After implementation, run these checks to ensure NO truncation remains:

1. **Search for all slice patterns:**
   ```bash
   grep -r "\[:\d\+\]" pydantic_ai_toolsets/toolsets/
   grep -r "\[:\d\+\].*\.\.\." pydantic_ai_toolsets/toolsets/
   grep -r "\[:\d\+\].*\.\.\." pydantic_ai_toolsets/evals/
   ```

2. **Verify agent-facing outputs:**

   - All `read_*` functions show full content
   - All storage `get_status_summary()` show full content
   - All `get_outputs_for_linking()` show full descriptions
   - No `...` truncation markers in any output

3. **Verify NO list limiting:**

   - All `read_*` functions show ALL items (no `[:N]` limits)
   - All "more" messages removed
   - All error messages show complete available lists (or at least many more items)
   - System prompts show all items, not limited subsets

4. **Evaluation code:**

   - Verify no truncation in `evals/base.py`
   - Verify no truncation in evaluation result processing

## Testing Considerations

After changes, verify:

1. Tool outputs show full content (no `...` truncation markers)
2. Storage summaries show full content
3. Linking descriptions contain full content
4. ALL list items are shown (no `[:N]` limits anywhere)
5. All "more" truncation messages removed
6. Error messages show complete available lists
7. Evaluation code shows full content
8. No regressions in functionality
9. Agent runs are effective with complete information
10. No `[:N]` patterns remain in agent-facing code

## Priority

**CRITICAL** - All truncation and limits MUST be removed. Agents rely on complete information for decision-making. Truncation and limits make agent runs ineffective and cause misbehavior.

**Zero tolerance policy**: No `[:N]` patterns should remain in any agent-facing code. Show everything always.
