doc-tasks-fixer（文档任务修复程序）

doc-tasks-fixer

Purpose

Automated fix skill that reads the latest audit/review report and applies fixes to TASKS (Implementation Tasks) documents. This skill bridges the gap between doc-tasks-reviewer / doc-tasks-audit findings and the corrected TASKS, enabling iterative improvement cycles.

Layer: 11 (TASKS Quality Improvement)

Upstream: SPEC documents, TSPEC documents, TASKS document, Audit/Review Report (TASKS-NN.A_audit_report_vNNN.md preferred; TASKS-NN.R_review_report_vNNN.md legacy-compatible)

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

When to Use This Skill

Use doc-tasks-fixer when:

• After Review: Run after doc-tasks-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 TASKS based on review reports
• Implementation Contract Issues: Contracts have incomplete or malformed structure

Do NOT use when:

• No review report exists (run doc-tasks-reviewer first)
• Creating new TASKS (use doc-tasks or doc-tasks-autopilot)
• Only need validation (use doc-tasks-validator)

Fix Phases

Phase 0: Fix Structure Violations (CRITICAL)

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

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

Required Structure:

Phase 3: Fix Element IDs

Converts invalid element IDs to correct format.

Conversion Rules:

Type Code Mapping (TASKS-specific):

Valid TASKS Type Codes:

Regex Patterns:

# Find element IDs with invalid type codes for TASKS
invalid_tasks_type = r'TASKS\.(\d{2})\.(?!18|30)(\d{2})\.(\d{2})'

# Find legacy patterns
legacy_task = r'###\s+TASK-(\d+):'
legacy_contract = r'###\s+CONTRACT-(\d+):'
legacy_dep = r'###\s+DEP-(\d+):'

Phase 4: Fix Content Issues

Addresses placeholders and incomplete content.

Fix Actions:

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'),
}

Contract Structure Repair:

Phase 5: Update References

Ensures traceability and cross-references are correct.

Fix Actions:

SPEC/TSPEC Traceability Fix:

<!-- Before -->
## TASKS.01.1801: Implement Authentication Handler

<!-- After -->
## TASKS.01.1801: Implement Authentication Handler

@spec: [SPEC-01.auth.handler](../09_SPEC/SPEC-01.md#auth-handler)
@tspec: [TSPEC-01.40.01](../10_TSPEC/TSPEC-01.md#tspec-01-40-01)

Phase 6: Handle Upstream Drift (Auto-Merge)

Addresses issues where upstream SPEC/TSPEC documents have changed since TASKS creation using a tiered auto-merge system.

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

Upstream/Downstream Context:

Tiered Auto-Merge Thresholds

The auto-merge system uses three tiers based on the percentage of change detected in upstream documents.

Change Percentage Calculation

def calculate_change_percentage(
    upstream_doc: str,
    tasks_doc: str,
    drift_cache: dict
) -> float:
    """Calculate upstream change percentage affecting TASKS.

    Args:
        upstream_doc: Path to SPEC or TSPEC document
        tasks_doc: Path to TASKS document
        drift_cache: Previous drift state from .drift_cache.json

    Returns:
        Change percentage (0.0 to 100.0)
    """
    # Count affected elements
    current_refs = extract_upstream_references(tasks_doc)
    cached_refs = drift_cache.get('references', {})

    # Calculate changes
    added_refs = set(current_refs) - set(cached_refs)
    removed_refs = set(cached_refs) - set(current_refs)
    modified_refs = [r for r in current_refs
                     if r in cached_refs and current_refs[r] != cached_refs[r]]

    total_refs = max(len(current_refs), len(cached_refs), 1)
    changed_refs = len(added_refs) + len(removed_refs) + len(modified_refs)

    return (changed_refs / total_refs) * 100

Task ID Pattern

Auto-generated tasks follow the pattern: TASK-NN-SSS

Full Pattern: TASK-{module:02d}-{sequence:03d}

Examples:

• TASK-01-001: First task in module 01
• TASK-03-042: 42nd task in module 03
• TASK-15-007: 7th task in module 15

def generate_task_id(module_number: int, existing_tasks: list[str]) -> str:
    """Generate next available task ID for a module.

    Args:
        module_number: The TASKS module number (NN from TASKS-NN)
        existing_tasks: List of existing task IDs in the module

    Returns:
        Next available task ID in format TASK-NN-SSS
    """
    # Extract sequence numbers from existing tasks
    pattern = re.compile(rf'TASK-{module_number:02d}-(\d{{3}})')
    sequences = [int(m.group(1)) for t in existing_tasks
                 if (m := pattern.match(t))]

    next_seq = max(sequences, default=0) + 1
    return f"TASK-{module_number:02d}-{next_seq:03d}"

No Deletion Policy

Tasks are NEVER deleted. Instead, they are marked as [CANCELLED] with a reason.

Rationale: Preserves audit trail, prevents orphaned downstream references, maintains traceability.

### TASK-01-003: Implement Rate Limiting

@spec: SPEC-01.rate_limit

<!-- After: Cancelled task -->

@spec: SPEC-01.rate_limit

Tier 1: Auto-Merge (< 5% Change)

Minor changes are automatically merged without human intervention.

Actions:

1. Generate new task IDs for added requirements
2. Update existing task references to new upstream versions
3. Increment patch version (e.g., 1.0.0 -> 1.0.1)
4. Update drift cache

    result.new_version = increment_patch_version(get_tasks_version(tasks_doc))

    return result

Tier 2: Auto-Merge with Changelog (5-15% Change)

Moderate changes are merged with detailed documentation.

Actions:

1. All Tier 1 actions
2. Generate detailed changelog entry
3. Mark affected tasks with [DRIFT-REVIEWED] marker
4. Increment minor version (e.g., 1.0.1 -> 1.1.0)
5. Update dependency links
6. Flag for optional human review

Handling Task Dependencies

When upstream drift affects tasks with dependencies, the auto-merge system handles cascading updates.

) -> list[str]:

            downstream_tasks.append(task_id)

            if change_type == 'cancelled':

File Naming: TASKS-NN.F_fix_report_vNNN.md

Location: Inside the TASKS nested folder: docs/11_TASKS/TASKS-NN_{slug}/

## Next Steps

1. Complete [TODO] placeholders in implementation tasks
2. Review upstream SPEC/TSPEC drift
3. Implement contract methods in TASKS-01_contracts.py
4. Run `/doc-tasks-reviewer TASKS-01` to verify fixes
5. Run mypy on contracts to ensure type compliance

Integration with Autopilot

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

flowchart LR
    subgraph Phase5["Phase 5: Review & Fix Cycle"]
        A[doc-tasks-reviewer] --> B{Score >= 90?}
        B -->|No| C[doc-tasks-fixer]
        C --> D{Iteration < Max?}
        D -->|Yes| A
        D -->|No| E[Flag for Manual Review]
        B -->|Yes| F[PASS]
    end

Autopilot Integration Points:

Error Handling

Recovery Actions

Backup Strategy

Before applying any fixes:

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

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.
