fix: remove arbitrary limits, fix hardcoded languages, and fix summarizer bugs

Browse Source 
Stage 1 quality improvements from the Arbitrary Limits & Dead Code audit:

Reference file truncation removed:
- codebase_scraper.py: remove code[:500] truncation at 5 locations — reference
  files now contain complete code blocks for copy-paste usability
- unified_skill_builder.py: remove issues[:20], releases[:10], body[:500],
  and code_snippet[:300] caps in reference files — full content preserved

Enhancement summarizer rewrite:
- enhance_skill_local.py: replace arbitrary [:5] code block cap with
  character-budget approach using target_ratio * content_chars
- Fix intro boundary bug: track code block state so intro never ends
  inside a code block, which was desynchronizing the parser
- Remove dead _target_lines variable (assigned but never used)
- Heading chunks now also respect the character budget

Hardcoded language fixes:
- unified_skill_builder.py: test examples use ex["language"] instead of
  always "python" for syntax highlighting
- how_to_guide_builder.py: add language field to HowToGuide dataclass,
  set from workflow at creation, used in AI enhancement prompt

Test fixes:
- test_enhance_skill_local.py: rename test to test_code_blocks_not_arbitrarily_capped,
  fix assertion to count actual blocks (```count // 2), use target_ratio=0.9

Documentation:
- Add Stage 1 plan, implementation summary, review, and corrected docs
- Update CHANGELOG.md with all changes

## [Unreleased]
### 📄 B2: Microsoft Word (.docx) Support & Stage 1 Quality Improvements
### Added
- **Microsoft Word (.docx) support** — New `skill-seekers word --docx <file>` command and `skill-seekers create document.docx` auto-detection. Full pipeline: mammoth → HTML → BeautifulSoup → sections → SKILL.md + references/
- `word_scraper.py` — `WordToSkillConverter` class (~600 lines) with heading/code/table/image/metadata extraction
- `arguments/word.py` — `add_word_arguments()` + `WORD_ARGUMENTS` dict
- `parsers/word_parser.py` — WordParser for unified CLI parser registry
- `tests/test_word_scraper.py` — comprehensive test suite (~300 lines)
- **`.docx` auto-detection** in `source_detector.py` — `create document.docx` routes to word scraper
- **`--help-word`** flag in create command for Word-specific help
- **Word support in unified scraper** — `_scrape_word()` method for multi-source scraping
- **`skill-seekers-word`** entry point in pyproject.toml
- **`docx` optional dependency group** — `pip install skill-seekers[docx]` (mammoth + python-docx)
### Fixed
- **Reference file code truncation removed** — `codebase_scraper.py` no longer truncates code blocks to 500 chars in reference files (5 locations fixed)
- **Enhancement code block limit replaced with token budget** — `enhance_skill_local.py` `summarize_reference()` now uses character-budget approach instead of arbitrary `[:5]` code block cap
- **Dead variable removed** — `_target_lines` in `enhance_skill_local.py:309` was assigned but never used
- **Intro boundary code block desync fixed** — `summarize_reference()` intro section could split inside a code block, desynchronizing the parser; now tracks code block state and ensures safe boundary
- **Test assertion corrected** — `test_code_blocks_not_arbitrarily_capped` now correctly counts code blocks (```count // 2) instead of raw marker count
- **Hardcoded `python` language in unified_skill_builder.py** — Test examples now use detected language (`ex["language"]`) instead of always `python`; code snippets no longer truncated to 300 chars
- **Hardcoded `python` language in how_to_guide_builder.py** — Added `language` field to `HowToGuide` dataclass, flows from test extractor → workflow → guide → AI prompt
- **GitHub reference file limits removed** — `unified_skill_builder.py` no longer caps issues at 20, releases at 10, or release bodies at 500 chars in reference files
- **GitHub scraper reference limits removed** — `github_scraper.py` no longer caps open_issues at 20 or closed_issues at 10
- **PDF scraper fixes** — Real API/LOCAL enhancement (was stub); removed `[:3]` reference file limit
- **Word scraper code detection** — Detect mammoth monospace `<p><br>` blocks as code (not `<pre>/<code>`)
- **Language detector method** — Fixed `detect_from_text` → `detect_from_code` in word scraper
### Changed
- **Enhancement summarizer architecture** — Character-budget approach respects `target_ratio` for both code blocks and heading chunks, replacing hard limits with proportional allocation

# Implementation Plan: Arbitrary Limits & Dead Code
**Generated:** 2026-02-24
**Scope:** Remove harmful arbitrary limits and implement critical TODO items
**Priority:** P0 (Critical) - P3 (Backlog)
---
## Part 1: Arbitrary Limits to Remove
### 🔴 P0 - Critical (Fix Immediately)
#### 1.1 Enhancement Code Block Limit
**File:** `src/skill_seekers/cli/enhance_skill_local.py:341`
**Current:**
```python
for _idx, block in code_blocks[:5]: # Max 5 code blocks
```
**Problem:** AI enhancement only sees 5 code blocks regardless of skill size. A skill with 100 code examples has 95% ignored during enhancement.
**Solution:**
```python
# Option A: Remove limit, use token counting instead
max_tokens = 4000 # Claude 3.5 Sonnet context for enhancement
current_tokens = 0
selected_blocks = []
for idx, block in code_blocks:
block_tokens = estimate_tokens(block)
if current_tokens + block_tokens > max_tokens:
break
selected_blocks.append((idx, block))
current_tokens += block_tokens
for _idx, block in selected_blocks:
```
**Effort:** 2 hours
**Impact:** High - Massive improvement in enhancement quality
**Breaking Change:** No
---
### 🟠 P1 - High Priority (Next Sprint)
#### 1.2 Reference File Code Truncation
**Files:**
- `src/skill_seekers/cli/codebase_scraper.py:422, 489, 575, 720, 746`
- `src/skill_seekers/cli/unified_skill_builder.py:1298`
**Current:**
```python
"code": code[:500], # Truncate long code blocks
```
**Problem:** Reference files should be comprehensive. Truncating code blocks at 500 chars breaks copy-paste functionality and harms skill utility.
**Solution:**
```python
# Remove truncation from reference files
"code": code, # Full code
# Keep truncation only for SKILL.md summaries (if needed)
```
**Effort:** 1 hour
**Impact:** High - Reference files become actually usable
**Breaking Change:** No (output improves)
---
#### 1.3 Table Row Limit in References
**File:** `src/skill_seekers/cli/word_scraper.py:595`
**Current:**
```python
for row in rows[:5]:
```
**Problem:** Tables in reference files truncated to 5 rows.
**Solution:** Remove `[:5]` limit from reference file generation. Keep limit only for SKILL.md summaries.
**Effort:** 30 minutes
**Impact:** Medium
**Breaking Change:** No
---
### 🟡 P2 - Medium Priority (Backlog)
#### 1.4 Pattern/Example Limits in Analysis
**Files:**
- `src/skill_seekers/cli/codebase_scraper.py:1898` - `examples[:10]`
- `src/skill_seekers/cli/github_scraper.py:1145, 1169` - Pattern limits
- `src/skill_seekers/cli/doc_scraper.py:608` - `patterns[:5]`
**Problem:** Pattern detection limited arbitrarily, missing edge cases.
**Solution:** Make configurable via `--max-patterns` flag with sensible default (50 instead of 5-10).
**Effort:** 3 hours
**Impact:** Medium - Better pattern coverage
**Breaking Change:** No
---
#### 1.5 Issue/Release Limits in GitHub Scraper
**File:** `src/skill_seekers/cli/github_scraper.py`
**Current:**
```python
for release in releases[:3]:
for issue in issues[:5]:
for issue in open_issues[:20]:
```
**Problem:** Hard limits without user control.
**Solution:** Add CLI flags:
```python
parser.add_argument("--max-issues", type=int, default=50)
parser.add_argument("--max-releases", type=int, default=10)
```
**Effort:** 2 hours
**Impact:** Medium - User control
**Breaking Change:** No
---
#### 1.6 Config File Display Limits
**Files:**
- `src/skill_seekers/cli/config_manager.py:540` - `jobs[:5]`
- `src/skill_seekers/cli/config_enhancer.py:165, 302` - Config file limits
**Problem:** Display truncated for UX reasons, but should have `--verbose` override.
**Solution:** Add verbose mode check:
```python
if verbose:
display_items = items
else:
display_items = items[:5] # Truncated for readability
```
**Effort:** 2 hours
**Impact:** Low-Medium
**Breaking Change:** No
---
### 🟢 P3 - Low Priority / Keep As Is
These limits are justified and should remain:
| Location | Limit | Justification |
|----------|-------|---------------|
| `word_scraper.py:553` | `all_code[:15]` | SKILL.md summary - full code in references |
| `word_scraper.py:567` | `examples[:5]` | Per-language summary in SKILL.md |
| `pdf_scraper.py:453, 472` | Same as above | Consistent with Word scraper |
| `word_scraper.py:658, 664` | `[:10], [:15]` | Key concepts list (justified for readability) |
| `adaptors/*.py` | `[:30000]` | API token limits (Claude/Gemini/OpenAI) |
| `base.py:208` | `[:500]` | Preview/summary text (not reference) |
---
## Part 1b: Hardcoded Language Issues
These are **data flow bugs** - the correct language is available upstream but hardcoded to `"python"` downstream.
### 🔴 P0 - Critical
#### 1.b.1 Test Example Code Snippets
**File:** `src/skill_seekers/cli/unified_skill_builder.py:1298`
**Current:**
```python
f.write(f"\n```python\n{ex['code_snippet'][:300]}\n```\n")
```
**Problem:** Hardcoded to `python` regardless of actual language.
**Available Data:** The `ex` dict from `TestExample.to_dict()` includes a `language` field.
**Fix:**
```python
lang = ex.get("language", "text")
f.write(f"\n```{lang}\n{ex['code_snippet'][:300]}\n```\n")
```
**Effort:** 1 minute
**Impact:** Medium - Syntax highlighting now correct
**Breaking Change:** No
---
#### 1.b.2 How-To Guide Language
**File:** `src/skill_seekers/cli/how_to_guide_builder.py:1018`
**Current:**
```python
"language": "python", # TODO: Detect from code
```
**Problem:** Language hardcoded in guide data sent to AI enhancement.
**Solution (3 one-line changes):**
1. **Add field to dataclass** (around line 70):
```python
@dataclass
class HowToGuide:
# ... existing fields ...
language: str = "python" # Source file language
```
2. **Set at creation** (line 955, in `_create_guide_from_workflow`):
```python
HowToGuide(
# ... other fields ...
language=primary_workflow.get("language", "python"),
)
```
3. **Use the field** (line 1018):
```python
"language": guide.language,
```
**Note:** The `primary_workflow` dict already carries the language field (populated by test example extractor upstream at line 169). Zero new imports needed.
**Effort:** 5 minutes
**Impact:** Medium - AI receives correct language context
**Breaking Change:** No
---
## Part 2: Dead Code / TODO Implementation
### 🔴 P0 - Critical TODOs (Implement Now)
#### 2.1 SMTP Email Notifications
**File:** `src/skill_seekers/sync/notifier.py:138`
**Current:**
```python
# TODO: Implement SMTP email sending
```
**Implementation:**
```python
def _send_email_smtp(self, to_email: str, subject: str, body: str) -> bool:
"""Send email via SMTP."""
import smtplib
from email.mime.text import MIMEText
smtp_host = os.environ.get("SKILL_SEEKERS_SMTP_HOST", "localhost")
smtp_port = int(os.environ.get("SKILL_SEEKERS_SMTP_PORT", "587"))
smtp_user = os.environ.get("SKILL_SEEKERS_SMTP_USER")
smtp_pass = os.environ.get("SKILL_SEEKERS_SMTP_PASS")
if not all([smtp_user, smtp_pass]):
logger.warning("SMTP credentials not configured")
return False
try:
msg = MIMEText(body)
msg["Subject"] = subject
msg["From"] = smtp_user
msg["To"] = to_email
with smtplib.SMTP(smtp_host, smtp_port) as server:
server.starttls()
server.login(smtp_user, smtp_pass)
server.send_message(msg)
return True
except Exception as e:
logger.error(f"Failed to send email: {e}")
return False
```
**Effort:** 4 hours
**Dependencies:** Environment variables for SMTP config
**Breaking Change:** No
---
### 🟠 P1 - High Priority (Next Sprint)
#### 2.2 Auto-Update Integration
**File:** `src/skill_seekers/sync/monitor.py:201`
**Current:**
```python
# TODO: Integrate with doc_scraper to rebuild skill
```
**Implementation:** Call existing scraper commands when changes detected.
```python
def _rebuild_skill(self, config_path: str) -> bool:
"""Rebuild skill when changes detected."""
import subprocess
# Use existing create command
result = subprocess.run(
["skill-seekers", "create", config_path, "--force"],
capture_output=True,
text=True,
timeout=300 # 5 minute timeout
)
return result.returncode == 0
```
**Effort:** 3 hours
**Dependencies:** Ensure `skill-seekers` CLI available in PATH
**Breaking Change:** No
---
#### 2.3 Language Detection in How-To Guides
**File:** `src/skill_seekers/cli/how_to_guide_builder.py:1018`
**Current:**
```python
"language": "python", # TODO: Detect from code
```
**Implementation:** Use existing `LanguageDetector`:
```python
from skill_seekers.cli.language_detector import LanguageDetector
detector = LanguageDetector(min_confidence=0.3)
language, confidence = detector.detect_from_text(code)
if confidence < 0.3:
language = "text" # Fallback
```
**Effort:** 1 hour
**Dependencies:** Existing LanguageDetector class
**Breaking Change:** No
---
### 🟡 P2 - Medium Priority (Backlog)
#### 2.4 Custom Transform System
**File:** `src/skill_seekers/cli/enhancement_workflow.py:439`
**Current:**
```python
# TODO: Implement custom transform system
```
**Purpose:** Allow users to define custom code transformations in workflow YAML.
**Implementation Sketch:**
```yaml
# Example workflow addition
transforms:
- name: "Remove boilerplate"
pattern: "Copyright \(c\) \d+"
action: "remove"
- name: "Normalize headers"
pattern: "^#{1,6} "
replacement: "## "
```
**Effort:** 8 hours
**Impact:** Medium - Power user feature
**Breaking Change:** No
---
#### 2.5 Vector Database Storage for Embeddings
**File:** `src/skill_seekers/embedding/server.py:268`
**Current:**
```python
# TODO: Store embeddings in vector database
```
**Implementation Options:**
- Option A: ChromaDB integration (already have adaptor)
- Option B: Qdrant integration (already have adaptor)
- Option C: SQLite with vector extension (simplest)
**Recommendation:** Start with SQLite + `sqlite-vec` for zero-config setup.
**Effort:** 6 hours
**Dependencies:** New dependency `sqlite-vec`
**Breaking Change:** No
---
### 🟢 P3 - Backlog / Low Priority
#### 2.6 URL Resolution in Sync Monitor
**File:** `src/skill_seekers/sync/monitor.py:136`
**Current:**
```python
# TODO: In real implementation, get actual URLs from scraper
```
**Note:** Current implementation uses placeholder URLs. Full implementation requires scraper to expose URL list.
**Effort:** 4 hours
**Impact:** Low - Current implementation works for basic use
**Breaking Change:** No
---

## Testing Strategy
### For Limit Removal
1. Create test skill with 100+ code blocks
2. Verify enhancement sees all code (or token-based limit)
3. Verify reference files contain complete code
4. Verify SKILL.md still has appropriate summaries
### For Hardcoded Language Fixes
1. Create skill from JavaScript/Go/Rust test examples
2. Verify `unified_skill_builder.py` outputs correct language tag in markdown
3. Verify `how_to_guide_builder.py` uses correct language in AI prompt
### For TODO Implementation
1. SMTP: Mock SMTP server test
2. Auto-update: Mock subprocess test
3. Language detection: Test with mixed-language code samples
---
## Success Metrics
| Metric | Before | After |
|--------|--------|-------|
| Code blocks in enhancement | 5 max | Token-based (40+) |
| Code truncation in refs | 500 chars | Full code |
| Table rows in refs | 5 max | All rows |
| Code snippet language | Always "python" | Correct language |
| Guide language | Always "python" | Source file language |
| Email notifications | Webhook only | SMTP + webhook |
| Auto-update | Manual only | Automatic |

# Stage 1 Implementation: CORRECTED
**Review Date:** 2026-02-24
**Status:** ✅ All issues fixed and verified
---
## Corrections Made
### Issue 1: enhance_skill_local.py - Token-Based Budget
**Problem:** Initial implementation removed the limit entirely, which could cause:
- Summarized output larger than original
- AI context window overflow
- Enhancement degradation/failure
**Solution:** Implemented proper token-based budgeting:
```python
# Budget is target_ratio of original content length
content_chars = len(content)
max_chars = int(content_chars * target_ratio)
current_chars = sum(len(line) for line in result)
# Priority 2: Add code blocks first (prioritize code examples) - no arbitrary limit
for _idx, block in code_blocks:
block_chars = sum(len(line) for line in block) + 1
if current_chars + block_chars > max_chars:
break
result.append("")
result.extend(block)
current_chars += block_chars
```
**Key Points:**
- Uses `target_ratio` parameter (default 0.3 = 30% of original)
- Includes as many code blocks as fit within budget
- No arbitrary cap of 5
- Respects the summarizer's purpose: compression
---
### Issue 2: unified_skill_builder.py - Reference File Truncations
**Changes Made:**
1. **Line 1299:** `[:300]` truncation removed
```python
# Before
f.write(f"\n```{lang}\n{ex['code_snippet'][:300]}\n```\n")
# After
f.write(f"\n```{lang}\n{ex['code_snippet']}\n```\n") # Full code
```
2. **Line 910:** `[:20]` issues limit removed
```python
# Before
for issue in github_data["issues"][:20]:
# After
for issue in github_data["issues"]: # All issues
```
3. **Line 923:** `[:10]` releases limit removed
```python
# Before
for release in github_data["releases"][:10]:
# After
for release in github_data["releases"]: # All releases
```
4. **Line 927:** `[:500]` release body truncation removed
```python
# Before
f.write(release["body"][:500])
# After
f.write(release["body"]) # Full release notes
```
---
## Test Updates
### test_enhance_skill_local.py
Updated `test_code_blocks_not_arbitrarily_capped` to:
- Use higher `target_ratio=0.6` to ensure budget for multiple code blocks
- Verify MORE than 5 code blocks can be included (proving limit removal)
- Match realistic summarizer behavior
```python
def test_code_blocks_not_arbitrarily_capped(self, tmp_path):
"""Code blocks should not be arbitrarily capped at 5 - should use token budget."""
enhancer = self._enhancer(tmp_path)
content = "\n".join(["Intro line"] * 10) + "\n"
for i in range(10):
content += f"```\ncode_block_{i}()\n```\n"
# Use higher ratio to ensure budget for code blocks
result = enhancer.summarize_reference(content, target_ratio=0.6)
code_block_count = result.count("```")
assert code_block_count > 5, f"Expected >5 code blocks, got {code_block_count}"
```
---
## Test Results
```
$ python -m pytest tests/test_enhance_skill_local.py tests/test_word_scraper.py \\
tests/test_codebase_scraper.py tests/test_cli_parsers.py
========================= 158 passed, 4 warnings =========================
```
### Coverage
- `test_enhance_skill_local.py`: 60 passed
- `test_word_scraper.py`: 44 passed
- `test_codebase_scraper.py`: 38 passed
- `test_cli_parsers.py`: 16 passed
---
## Final Verification
| Change | Status | Verification |
|--------|--------|--------------|
| Token-based code block budget | ✅ | Uses target_ratio of original content |
| unified_skill_builder [:300] | ✅ | Removed, full code in references |
| unified_skill_builder issues[:20] | ✅ | Removed, all issues included |
| unified_skill_builder releases[:10] | ✅ | Removed, all releases included |
| unified_skill_builder body[:500] | ✅ | Removed, full release notes |
| All other Stage 1 changes | ✅ | No regressions |
---
## Files Modified (Final)
| File | Lines | Changes |
|------|-------|---------|
| `enhance_skill_local.py` | ~341-370 | Token-based budget instead of no limit |
| `codebase_scraper.py` | 5 locations | [:500] truncation removal |
| `unified_skill_builder.py` | 1299, 910, 923, 927 | All truncations removed |
| `how_to_guide_builder.py` | 108, 969, 1020 | Language field (unchanged) |
| `test_enhance_skill_local.py` | ~359-369 | Test updated for new behavior |
---
## Key Lessons
1. **Summarizers need limits** - Just not arbitrary ones. Token/content budget is correct.
2. **Reference files should be comprehensive** - All truncations removed.
3. **Tests must match intent** - Updated test to verify "more than 5" not "all 10".

# Stage 1 Implementation Summary
**Completed:** 2026-02-24
**Status:** ✅ All tasks completed, all tests passing
---
## Changes Made
### 1. Removed [:5] Code Block Limit in Enhancement (P0)
**File:** `src/skill_seekers/cli/enhance_skill_local.py:341`
**Before:**
```python
for _idx, block in code_blocks[:5]: # Max 5 code blocks
```
**After:**
```python
for _idx, block in code_blocks: # All code blocks - no arbitrary limit
```
**Impact:** AI enhancement now sees ALL code blocks instead of just 5. Previously, a skill with 100 code examples had 95% ignored during enhancement. Now 100% are included.
---
### 2. Removed [:500] Code Truncation from References (P1)
**File:** `src/skill_seekers/cli/codebase_scraper.py`
**Locations Fixed:**
- Line 422: `"code": code[:500]` → `"code": code`
- Line 489: `"code": cb.code[:500]` → `"code": cb.code`
- Line 575: `"code": code[:500]` → `"code": code`
- Line 720: `"code": cb.code[:500]` → `"code": cb.code`
- Line 746: `"code": cb.code[:500]` → `"code": cb.code`
**Impact:** Reference files now contain complete code blocks. Users can copy-paste full examples instead of truncated snippets.
---
### 3. Word Scraper Table Limits (Verified Correct)
**File:** `src/skill_seekers/cli/word_scraper.py`
**Finding:** The `[:5]` limit at line 595 is in **SKILL.md** (summary document), not reference files. Reference files at line 412 already have no limit.
**Status:** No changes needed - implementation was already correct.
---
### 4. Fixed Hardcoded Language in unified_skill_builder.py (P0)
**File:** `src/skill_seekers/cli/unified_skill_builder.py:1298`
**Before:**
```python
f.write(f"\n```python\n{ex['code_snippet'][:300]}\n```\n")
```
**After:**
```python
lang = ex.get("language", "text")
f.write(f"\n```{lang}\n{ex['code_snippet'][:300]}\n```\n")
```
**Impact:** Code snippets in test examples now use correct language for syntax highlighting (e.g., `javascript`, `go`, `rust` instead of always `python`).
---
### 5. Fixed Hardcoded Language in how_to_guide_builder.py (P0)
**File:** `src/skill_seekers/cli/how_to_guide_builder.py`
**Change 1 - Dataclass (line ~108):**
```python
# Added field
language: str = "python" # Source file language
```
**Change 2 - Creation (line 969):**
```python
HowToGuide(
# ... other fields ...
language=primary_workflow.get("language", "python"),
)
```
**Change 3 - Usage (line 1020):**
```python
# Before:
"language": "python", # TODO: Detect from code
# After:
"language": guide.language,
```
**Impact:** AI enhancement for how-to guides now receives the correct language context instead of always assuming Python. The language flows from test example extractor → workflow → guide → AI prompt.

# Stage 1 Implementation: Comprehensive Review
**Review Date:** 2026-02-24
**Status:** ✅ All changes verified and tested
---
## Executive Summary
All Stage 1 tasks completed successfully. One test was updated to reflect the new (correct) behavior. All 158 targeted tests pass.
---
## Detailed Change Review
### Change 1: Remove [:5] Code Block Limit (enhance_skill_local.py)
**Location:** `src/skill_seekers/cli/enhance_skill_local.py:341`
**Change:**
```python
# Before
for _idx, block in code_blocks[:5]: # Max 5 code blocks
# After
for _idx, block in code_blocks: # All code blocks - no arbitrary limit
```
**Data Flow Verification:**
- ✅ `summarize_reference()` is only called when skill size > 30KB or summarization explicitly requested
- ✅ 50KB hard limit exists at `read_reference_files()` stage via `LOCAL_CONTENT_LIMIT`
- ✅ Headings still limited to 10 (intentional - prioritizes code over prose)
**Test Update Required:**
- Updated `test_code_blocks_capped_at_five` → `test_all_code_blocks_included`
- Test now verifies ALL code blocks are included (10/10, not capped at 5)
**Risk Assessment:** LOW
- Large prompts are bounded by existing 50KB limit
- Summarization only triggered for large skills (>30KB)
- Performance impact minimal due to early filtering
---
### Change 2: Remove [:500] Code Truncation (codebase_scraper.py)
**Locations:** Lines 422, 489, 575, 720, 746
**Change Pattern:**
```python
# Before
"code": code[:500], # Truncate long code blocks
# After
"code": code, # Full code - no truncation
```
**Data Flow Verification:**
- ✅ `full_length` field preserved for backward compatibility
- ✅ Affects markdown and RST structure extraction only
- ✅ Used in reference file generation (comprehensive docs)
**Impact:**
- Reference files now contain complete code examples
- Copy-paste functionality restored
- No breaking changes to data structure
**Risk Assessment:** LOW
- Only affects output quality, not structure
- Memory impact minimal (modern systems handle KBs of text)
---
### Change 3: Word Scraper Table Limits (Verified - No Change Needed)
**Investigation:**
- Line 412: `for row in rows` (reference files) - NO LIMIT ✅
- Line 595: `for row in rows[:5]` (SKILL.md) - INTENTIONAL ✅
**Conclusion:** Implementation was already correct. SKILL.md summary justifiably limits tables to 5 rows; reference files have all rows.
---
### Change 4: Fix Hardcoded Language (unified_skill_builder.py:1298)
**Change:**
```python
# Before
f.write(f"\n```python\n{ex['code_snippet'][:300]}\n```\n")
# After
lang = ex.get("language", "text")
f.write(f"\n```{lang}\n{ex['code_snippet'][:300]}\n```\n")
```
**Data Flow Verification:**
- ✅ `ex` dict comes from `TestExample.to_dict()` which includes `language` field
- ✅ `TestExample.language` populated by extractor based on file extension
- ✅ Fallback to "text" for unknown languages (safe)
**Supported Languages:** Python, JavaScript, TypeScript, Go, Rust, Java, C#, PHP, Ruby, GDScript
**Risk Assessment:** LOW
- Graceful fallback to "text" if language missing
- Only affects markdown rendering (syntax highlighting)
---
### Change 5: HowToGuide Language Field (3 changes)
**Change 1 - Dataclass (line ~108):**
```python
language: str = "python" # Source file language
```
**Change 2 - Creation (line 969):**
```python
language=primary_workflow.get("language", "python"),
```
**Change 3 - Usage (line 1020):**
```python
"language": guide.language, # Was: "python"
```
**Data Flow Verification:**
- ✅ `primary_workflow["language"]` already populated upstream (line 170 confirms pattern)
- ✅ `extract_steps_from_workflow()` already uses `workflow.get("language", "python")`
- ✅ Language flows: TestExample → workflow dict → HowToGuide → AI prompt
**Risk Assessment:** LOW
- Existing pattern confirmed in codebase
- Default "python" maintains backward compatibility
- AI enhancement receives correct context
---
## Test Results
### Before Fix
```
test_code_blocks_capped_at_five FAILED
AssertionError: assert 10 <= 5 # Expected with new behavior
```
### After Fix
```
$ python -m pytest tests/test_enhance_skill_local.py tests/test_word_scraper.py \\
tests/test_codebase_scraper.py tests/test_cli_parsers.py -v
========================= 158 passed, 4 warnings =========================
```
### Test Coverage
- ✅ `test_enhance_skill_local.py` - 60 passed
- ✅ `test_word_scraper.py` - 44 passed
- ✅ `test_codebase_scraper.py` - 38 passed
- ✅ `test_cli_parsers.py` - 16 passed
---
## Data Flow Validation
### Language Flow (Test Example → AI Prompt)
```
File (test_example_extractor.py)
→ _detect_language() detects from extension
→ TestExample created with language field
→ to_dict() includes "language" key
→ unified_skill_builder.py reads ex["language"]
→ Correct markdown lang tag generated
```
### Language Flow (HowToGuide)
```
Workflow dict (has "language" from TestExample)
→ _create_guide_from_workflow() passes to HowToGuide
→ guide.language set
→ _enhance_guide_with_ai() uses guide.language
→ AI prompt has correct language context
```
### Code Block Flow
```
Reference content
→ read_reference_files() (50KB max)
→ summarize_reference() if >30KB
→ ALL code blocks included (was: max 5)
→ prompt sent to Claude Code
```
---
## Potential Gaps & Future Considerations
### Gap 1: No Token-Based Limit (Minor)
**Current:** All code blocks included until 50KB character limit
**Future:** Could implement token-based limit for more precise control
**Impact:** Low - 50KB char limit is effective proxy
### Gap 2: Headings Still Capped at 10
**Current:** `headings_added < 10` in summarize_reference()
**Question:** Should headings also be unlimited?
**Answer:** Probably not - code is more valuable than headings for enhancement
### Gap 3: No Validation of Language Field
**Current:** `ex.get("language", "text")` - no validation
**Risk:** Invalid language codes could break syntax highlighting
**Mitigation:** Low risk - markdown renderers graceful with unknown lang tags
### Gap 4: RST Code Block Truncation
**Status:** Fixed (line 575)
**Note:** Same pattern as markdown, same fix applied
