doc-ears-fixer

doc-ears-fixer

Purpose

Automated fix skill that reads the latest audit/review report and applies fixes to EARS (Easy Approach to Requirements Syntax) documents. This skill bridges the gap between doc-ears-reviewer/doc-ears-audit (which identify issues) and the corrected EARS, enabling iterative improvement cycles.

Layer: 3 (EARS Quality Improvement)

Upstream: EARS document, Audit/Review Report (EARS-NN.A_audit_report_vNNN.md preferred, EARS-NN.R_review_report_vNNN.md legacy), PRD (source requirements)

Downstream: Fixed EARS, Fix Report (EARS-NN.F_fix_report_vNNN.md)

---

When to Use This Skill

Use doc-ears-fixer when:

• After Review: Run after doc-ears-reviewer identifies issues
• Iterative Improvement: Part of Review -> Fix -> Review cycle
• Automated Pipeline: CI/CD integration for quality gates
• Batch Fixes: Apply fixes to multiple EARS based on review reports

Do NOT use when:

• No audit/review report exists (run doc-ears-audit or doc-ears-reviewer first)
• Creating new EARS (use doc-ears or doc-ears-autopilot)
• Only need validation (use doc-ears-validator)

Fix Phases

Phase 0: Fix Structure Violations (CRITICAL)

Fixes EARS documents that are not in nested folders. This phase runs FIRST because all subsequent phases depend on correct folder structure.

Nested Folder Rule: ALL EARS MUST be in nested folders regardless of document size.

Required Structure:

EARS Type	Required Location
Monolithic	docs/03_EARS/EARS-NN_{slug}/EARS-NN_{slug}.md

Fix Actions:

Issue Code	Issue	Fix Action
REV-STR001	EARS not in nested folder	Create folder, move file, update all links
REV-STR002	EARS folder name doesn't match EARS ID	Rename folder to match
REV-STR003	Monolithic EARS >25KB should be sectioned	Flag for manual review

Structure Fix Workflow:

def fix_ears_structure(ears_path: str) -> list[Fix]:
    """Fix EARS structure violations."""
    fixes = []

    filename = os.path.basename(ears_path)
    parent_folder = os.path.dirname(ears_path)

    # Extract EARS ID and slug from filename
    match = re.match(r'EARS-(\d+)_([^/]+)\.md', filename)
    if not match:
        return []  # Cannot auto-fix invalid filename

    ears_id = match.group(1)
    slug = match.group(2)
    expected_folder = f"EARS-{ears_id}_{slug}"

    # Check if already in nested folder
    if os.path.basename(parent_folder) != expected_folder:
        # Create nested folder
        new_folder = os.path.join(os.path.dirname(parent_folder), expected_folder)
        os.makedirs(new_folder, exist_ok=True)

        # Move file
        new_path = os.path.join(new_folder, filename)
        shutil.move(ears_path, new_path)
        fixes.append(f"Moved {ears_path} to {new_path}")

        # Update upstream links in moved file
        content = Path(new_path).read_text()
        updated_content = content.replace('../02_PRD/', '../../02_PRD/')
        updated_content = updated_content.replace('../01_BRD/', '../../01_BRD/')
        Path(new_path).write_text(updated_content)
        fixes.append(f"Updated relative links for nested folder structure")

    return fixes

Link Path Updates After Move:

Original Path	Updated Path
../02_PRD/PRD-01_slug/PRD-01.md	../../02_PRD/PRD-01_slug/PRD-01.md
../01_BRD/BRD-01_slug/BRD-01.md	../../01_BRD/BRD-01_slug/BRD-01.md

Phase 1: Create Missing Files

Creates files that are referenced but don't exist.

Scope:

Missing File	Action	Template Used
EARS-00_GLOSSARY.md	Create EARS glossary	Glossary template
EARS-NN_APPENDIX_*.md	Create appendix placeholder	Appendix template
Pattern library files	Create placeholder with TODO sections	Pattern template
Constraint files	Create placeholder	Constraint template

EARS Glossary Template:

---
title: "EARS-00: Requirements Glossary"

  - ears
  - glossary
  - reference
custom_fields:

| Unwanted Behavior | Exception handling requirement | Pattern type |
| State-Driven | Active in specific state | Pattern type |
| Optional Feature | Conditionally included requirement | Pattern type |
| Complex | Multi-condition requirement | Pattern type |

## Requirement Keywords

| Term | Definition | Context |
|------|------------|---------|
| SHALL | Mandatory requirement | Normative |
| SHOULD | Recommended requirement | Advisory |
| MAY | Optional requirement | Permissive |
| MUST | Absolute requirement | Critical |

## Domain Terms

### Phase 2: Fix Broken Links

Updates links to point to correct locations.

**Fix Actions**:

| Issue Code | Issue | Fix Action |
|------------|-------|------------|
| REV-L001 | Broken internal link | Update path or create target file |
| REV-L002 | External link unreachable | Add warning comment, keep link |
| REV-L003 | Absolute path used | Convert to relative path |
| REV-L004 | Broken PRD reference | Update to correct PRD path |

**Path Resolution Logic**:

```python
def fix_link_path(ears_location: str, target_path: str) -> str:
    """Calculate correct relative path based on EARS location."""

    # Monolithic EARS: docs/03_EARS/EARS-01.md
    # Sectioned EARS: docs/03_EARS/EARS-01_slug/EARS-01.3_section.md

    if is_sectioned_ears(ears_location):
        # Need to go up one more level
        return "../" + calculate_relative_path(ears_location, target_path)
    else:
        return calculate_relative_path(ears_location, target_path)

PRD Link Fix:

EARS Type	Original Link	Fixed Link
Monolithic	../02_PRD/PRD-01.md	../02_PRD/PRD-01.md
Sectioned	../02_PRD/PRD-01.md	../../02_PRD/PRD-01.md

---

Phase 3: Fix Element IDs

Converts invalid element IDs to correct format.

Conversion Rules:

Pattern	Issue	Conversion
EARS.NN.01.SS	Code 01 invalid for EARS	EARS.NN.25.SS (EARS Statement)
EARS.NN.22.SS	Code 22 invalid for EARS	EARS.NN.26.SS (Constraint Statement)
REQ-XXX	Legacy pattern	EARS.NN.25.SS
CON-XXX	Legacy pattern	EARS.NN.26.SS
PAT-XXX	Legacy pattern	EARS.NN.25.SS

Type Code Mapping (EARS-specific valid codes: 25, 26):

Invalid Code	Valid Code	Element Type
01	25	EARS Statement
02	25	EARS Statement
03	26	Constraint Statement
05	25	EARS Statement
06	26	Constraint Statement
22	25	EARS Statement
33	26	Constraint Statement

Regex Patterns:

# Find element IDs with invalid type codes for EARS
invalid_ears_type_01 = r'EARS\.(\d{2})\.01\.(\d{2})'
replacement_01 = r'EARS.\1.25.\2'

invalid_ears_type_22 = r'EARS\.(\d{2})\.22\.(\d{2})'
replacement_22 = r'EARS.\1.26.\2'

# Find legacy patterns
legacy_req = r'###\s+REQ-(\d+):'
legacy_con = r'###\s+CON-(\d+):'
legacy_pat = r'###\s+PAT-(\d+):'

---

Phase 4: Fix Content Issues

Addresses placeholders, incomplete content, and EARS-specific syntax issues.

Fix Actions:

Issue Code	Issue	Fix Action
REV-P001	[TODO] placeholder	Flag for manual completion (cannot auto-fix)
REV-P002	[TBD] placeholder	Flag for manual completion (cannot auto-fix)
REV-P003	Template date YYYY-MM-DD	Replace with current date
REV-P004	Template name [Name]	Replace with metadata author or flag
REV-P005	Empty section	Add minimum template content
REV-E001	Missing EARS keyword (shall/should/may)	Flag for manual review
REV-E002	Invalid EARS pattern structure	Flag for manual review
REV-E003	Missing trigger condition	Flag for manual review

Auto-Replacements:

replacements = {
    'YYYY-MM-DDTHH:MM:SS': datetime.now().strftime('%Y-%m-%dT%H:%M:%S'),
    'YYYY-MM-DD': datetime.now().strftime('%Y-%m-%d'),
    'MM/DD/YYYY': datetime.now().strftime('%m/%d/%Y'),
    '[Current date]': datetime.now().strftime('%Y-%m-%dT%H:%M:%S'),
    '[System Name]': extract_system_name_from_metadata(),
}

EARS Pattern Validation:

Pattern Type	Required Structure	Auto-Fix
Ubiquitous	"The [system] shall [action]"	No (flag)
Event-Driven	"When [trigger], the [system] shall [action]"	No (flag)
State-Driven	"While [state], the [system] shall [action]"	No (flag)
Unwanted	"If [condition], then the [system] shall [action]"	No (flag)
Optional	"Where [feature], the [system] shall [action]"	No (flag)

---

Phase 5: Update References

Ensures traceability and cross-references are correct.

Fix Actions:

Issue	Fix Action
Missing @ref: for created files	Add reference tag
Incorrect cross-EARS path	Update to correct relative path
Missing PRD traceability	Add PRD reference with @trace: PRD-NN
Missing traceability entry	Add to traceability matrix

Traceability Format:

<!-- Traceability to PRD -->
@trace: PRD-01.22.01 -> EARS-01.25.01

<!-- Reference to upstream -->
@ref: PRD-01 Section 3 (../02_PRD/PRD-01.md#3-feature-requirements)

---

Phase 6: Handle Upstream Drift (Auto-Merge)

Addresses issues where upstream PRD documents have changed since EARS creation. This phase implements a tiered auto-merge system based on drift percentage.

6.0.1 Hash Validation Fixes

FIX-H001: Invalid Hash Placeholder

Trigger: Hash contains placeholder instead of SHA-256

Fix:

sha256sum <upstream_file_path> | cut -d' ' -f1

Update cache with: sha256:<64_hex_output>

FIX-H002: Missing Hash Prefix

Trigger: 64 hex chars but missing sha256: prefix

Fix: Prepend sha256: to value

FIX-H003: Upstream File Not Found

Trigger: Cannot compute hash (file missing)

Fix: Set drift_detected: true, add to manual review

Code	Description	Auto-Fix	Severity
FIX-H001	Replace placeholder hash with actual SHA-256	Yes	Error
FIX-H002	Add missing sha256: prefix	Yes	Warning
FIX-H003	Upstream file not found	Partial	Error

---

Upstream: PRD (Layer 2) Downstream: BDD (Layer 4) ID Pattern: EARS.NN.TT.SS (e.g., EARS.01.25.13)

Drift Issue Codes (from doc-ears-reviewer Check #9)

Code	Severity	Description	Auto-Fix Tier
REV-D001	Warning	PRD modified after EARS	Tier 1-2
REV-D002	Warning	Referenced PRD section content changed	Tier 1-3
REV-D003	Info	PRD version incremented	Tier 1
REV-D004	Info	New features added to PRD	Tier 1-2
REV-D005	Error	Critical PRD modification (>20% change)	Tier 3

Tiered Auto-Merge System

Tier Classification:

Tier	Change %	Auto-Merge	Version Action	Description
Tier 1	< 5%	Full auto-merge	Patch (+0.0.1)	Additions, threshold updates
Tier 2	5-15%	Auto-merge with changelog	Minor (+0.1.0)	Significant additions, minor modifications
Tier 3	> 15%	Archive + regenerate	Major (+1.0.0)	Structural changes, major content drift

Drift Acknowledgment Workflow

When drift is flagged but no EARS update is needed:

1. Run /doc-ears-fixer EARS-01 --acknowledge-drift
2. Fixer prompts: "Review drift for PRD-01.md Section 8?"
3. User confirms no EARS changes needed
4. Fixer adds to acknowledged_drift array
5. Future reviews skip this drift until upstream changes again

Downstream Notification

After any auto-merge, notify downstream BDD documents:

def notify_downstream(ears_id: str, changes: list[dict]) -> None:
    """
    Create notification for downstream BDD documents.

    Args:
        ears_id: EARS document ID (e.g., "EARS-01")
        changes: List of changes made during auto-merge
    """
    notification = {
        "type": "UPSTREAM_CHANGE",
        "source": ears_id,
        "timestamp": datetime.now().isoformat(),
        "changes": changes,
        "action_required": "Run /doc-bdd-fixer to sync"
    }

    # Write to .downstream_notifications.json
    write_notification(f"docs/04_BDD/.downstream_notifications.json", notification)

Output Artifacts

Fix Report

Nested Folder Rule: ALL EARS use nested folders (EARS-NN_{slug}/) regardless of size. Fix reports are stored alongside the EARS document in the nested folder.

File Naming: EARS-NN.F_fix_report_vNNN.md

Location: Inside the EARS nested folder: docs/03_EARS/EARS-NN_{slug}/

Structure:

---
title: "EARS-NN.F: Fix Report v001"
tags:
  - ears
  - fix-report
  - quality-assurance
custom_fields:
  document_type: fix-report
  artifact_type: EARS-FIX

Integration with Autopilot

This skill is invoked by doc-ears-autopilot in the Review -> Fix cycle:

flowchart LR
    subgraph Phase5["Phase 5: Review & Fix Cycle"]
        A[doc-ears-reviewer] --> B{Score >= 85?}
        B -->|No| C[doc-ears-fixer]
        C --> D{Iteration < Max?}
        D -->|Yes| A
        D -->|No| E[Flag for Manual Review]
        B -->|Yes| F[PASS]
    end

Autopilot Integration Points:

Phase	Action	Skill
Phase 5a	Run initial review	doc-ears-reviewer
Phase 5b	Apply fixes if issues found	doc-ears-fixer
Phase 5c	Re-run review	doc-ears-reviewer
Phase 5d	Repeat until pass or max iterations	Loop

Error Handling

Recovery Actions

Error	Action
Audit/review report not found	Prompt to run doc-ears-audit or doc-ears-reviewer first
Cannot create file (permissions)	Log error, continue with other fixes
Cannot parse report	Abort with clear error message
Max iterations exceeded	Generate report, flag for manual review
PRD not found	Log warning, skip PRD-dependent fixes

Backup Strategy

Before applying any fixes:

1. Create backup in tmp/backup/EARS-NN_YYYYMMDD_HHMMSS/
2. Copy all EARS files to backup location
3. Apply fixes to original files
4. If error during fix, restore from backup

Version History

Version	Date	Changes
2.2	2026-02-26	Migrated frontmatter to metadata; added compatibility for EARS-NN.A_audit_report_vNNN.md (preferred) with legacy EARS-NN.R_review_report_vNNN.md; defined deterministic precedence (latest timestamp, then .A_ over .R_ on ties)
2.1	2026-02-11	Structure Compliance: Added Phase 0 for nested folder rule enforcement (REV-STR001-STR003); Runs FIRST before other fix phases
2.0	2026-02-10	Enhanced Phase 6 with tiered auto-merge system; Tier 1 (< 5%): auto-merge additions with patch version; Tier 2 (5-15%): auto-merge with changelog and minor version; Tier 3 (> 15%): archive + regenerate with major version; No-deletion policy with deprecation markers; Auto-generated IDs (EARS.NN.TT.SS pattern); Enhanced drift cache with merge history; Downstream BDD notification system
1.0	2026-02-10	Initial skill creation; 6-phase fix workflow; Glossary and pattern file creation; Element ID conversion for EARS codes (25, 26); Broken link fixes; PRD drift detection; EARS pattern syntax validation; Integration with autopilot Review->Fix cycle

Implementation Plan Consistency (IPLAN-004)

• Treat plan-derived outputs as valid source mode and verify intent preservation from implementation plan scope/objectives.
• Validate upstream autopilot precedence assumption: --iplan > --ref > --prompt.
• Flag objective/scope conflicts between plan context and artifact output as blocking issues requiring clarification.
• Do not introduce legacy fallback paths such as docs-v2.0/00_REF.
