Tech Debt

You are conducting a technical debt analysis to catalog, prioritize, and plan remediation of debt across the codebase.

MANDATORY GRAPH LOOKUP (read before debt scan)

First resolve the bundled helpers:

# Locate Draft's bundled helpers (cwd is the user's project; ${CLAUDE_PLUGIN_ROOT}
# is not exported into skill Bash). See core/shared/tool-resolver.md.
DRAFT_TOOLS="${DRAFT_PLUGIN_ROOT:-$(cat ~/.cache/draft/plugin-root 2>/dev/null)}/scripts/tools"
[ -d "$DRAFT_TOOLS" ] || DRAFT_TOOLS="$(ls -d ~/.claude/plugins/cache/*/draft/*/scripts/tools 2>/dev/null | sort -V | tail -1)"
[ -d "$DRAFT_TOOLS" ] || DRAFT_TOOLS="$(ls -d ~/.claude/plugins/marketplaces/*draft*/scripts/tools 2>/dev/null | tail -1)"
[ -d "$DRAFT_TOOLS" ] || DRAFT_TOOLS="$PWD/scripts/tools"

When draft/graph/schema.yaml exists, this skill must follow the graph-first lookup contract in core/shared/graph-query.md §Mandatory Lookup Contract. Tech-debt prioritization is fundamentally driven by graph data:

1. Run "$DRAFT_TOOLS/hotspot-rank.sh" --repo . — rank candidates by fanIn × complexity to surface high-leverage debt first.
2. Query "$DRAFT_TOOLS/graph-arch.sh" --repo . and run "$DRAFT_TOOLS/cycle-detect.sh" --repo . — flag debt in modules involved in cycles as higher priority.
3. Run "$DRAFT_TOOLS/cycle-detect.sh" --repo . to enumerate dependency cycles — every cycle is a candidate architecture-debt entry.
4. For each catalogued finding, run "$DRAFT_TOOLS/graph-impact.sh" --repo . --file <path> so the remediation plan includes blast-radius.

Filesystem grep (e.g. scan-markers.sh) is still primary for TODO/FIXME marker discovery — markers are source-text, not graph-derived. The graph governs prioritization, the marker scan governs discovery.

Red Flags — STOP if you're:

See shared red flags — applies to all code-touching skills.

Skill-specific:

• Flagging intentional design choices as debt (check tech-stack.md accepted patterns first)
• Cataloging debt without understanding the business context
• Setting priorities without considering team capacity
• Recommending "rewrite from scratch" without exhausting incremental options
• Ignoring the existing guardrails.md conventions

Not all shortcuts are debt. Check accepted patterns before flagging.

Pre-Check

0. Capture Git Context

Before starting, capture the current git state:

git branch --show-current # Current branch name
git rev-parse --short HEAD # Current commit hash

Store this for the report header. All findings are relative to this specific branch/commit.

1. Verify Draft Context

ls draft/ 2>/dev/null

If draft/ doesn't exist, this skill can still run standalone with reduced context.

2. Load Draft Context (if available)

Read and follow the base procedure in core/shared/draft-context-loading.md.

Step 1: Parse Arguments

• /draft:tech-debt — Project-wide scan (default)
• /draft:tech-debt module <name> — Module-scoped scan
• /draft:tech-debt category <type> — Filter by category (code, architecture, test, dependency, documentation, infrastructure)
• /draft:tech-debt <path> — Scan specific directory/file pattern

Step 2: Load Context

1. Read draft/tech-stack.md — Critical: "Accepted Patterns" section. Do NOT flag these as debt.
2. Read draft/guardrails.md — Learned conventions (skip) and anti-patterns (always flag)
3. Read draft/.ai-context.md — Module boundaries, invariants, known constraints
4. Read draft/product.md — Business priorities for impact assessment
5. Read draft/workflow.md — Team conventions and toolchain for feasibility assessment

Step 3: Scan for Debt

Scan the codebase systematically across all seven categories. For each finding, record: location (file:line OR track id for Process Debt), description, evidence, and category.

Category 1: Code Debt

For TODO/FIXME/HACK/XXX/DEPRECATED markers, prefer the deterministic scan-markers.sh wrapper — it emits JSON [{path,line,marker,text,sha,author,introduced,age_days}] with blame ages already computed. Resolve via the canonical tool resolver (see core/shared/tool-resolver.md):

# Locate Draft's bundled helpers (cwd is the user's project; ${CLAUDE_PLUGIN_ROOT}
# is not exported into skill Bash). See core/shared/tool-resolver.md.
DRAFT_TOOLS="${DRAFT_PLUGIN_ROOT:-$(cat ~/.cache/draft/plugin-root 2>/dev/null)}/scripts/tools"
[ -d "$DRAFT_TOOLS" ] || DRAFT_TOOLS="$(ls -d ~/.claude/plugins/cache/*/draft/*/scripts/tools 2>/dev/null | sort -V | tail -1)"
[ -d "$DRAFT_TOOLS" ] || DRAFT_TOOLS="$(ls -d ~/.claude/plugins/marketplaces/*draft*/scripts/tools 2>/dev/null | tail -1)"
[ -d "$DRAFT_TOOLS" ] || DRAFT_TOOLS="$PWD/scripts/tools"
[ -x "$DRAFT_TOOLS/scan-markers.sh" ] && bash "$DRAFT_TOOLS/scan-markers.sh" --root .
# Fallback when script unavailable: grep -rn 'TODO\|FIXME\|HACK\|XXX\|DEPRECATED' .

Use the JSON output to prioritise: markers with age_days > 180 are stale and should be promoted to tracked tech debt.

Marker context gate (Ground-Truth Discipline G1): scan-markers.sh produces candidates, not findings. Before promoting a TODO/FIXME/HACK/XXX/DEPRECATED marker to your debt catalog, Read the surrounding 10–20 lines at that file:line. Many markers are justified (intentional deferrals with ownership) or already addressed (the marker rotted, the work shipped). A debt entry whose Evidence is "marker exists" without a Read is a Ground-Truth Red Flag — produce false positives and reviewer churn.

• Complex functions (cyclomatic complexity >10, deep nesting >4 levels)
• Duplicated code blocks (>20 lines similar across multiple locations)
• TODO/FIXME/HACK/XXX comments (especially old ones — check git blame age via scan-markers.sh above)
• Dead code (unreachable branches, unused exports, commented-out blocks)
• Inconsistent naming patterns within the same module
• Long functions (>100 lines without clear separation of concerns)
• God classes (>500 lines, >10 public methods, mixed responsibilities)
• Magic numbers and hardcoded strings that should be constants
• Deeply nested callbacks or promise chains (callback hell)

Category 2: Architecture Debt

• Dependency cycles between modules (A depends on B depends on A)
• Tight coupling (modules with >5 direct cross-references)
• Layer violations (UI calling DB directly, business logic in controllers)
• Missing abstractions (repeated patterns without shared interface)
• Monolith tendencies (single module >50% of codebase)
• Inconsistent data flow patterns (some modules use events, others direct calls)
• Missing or bypassed API boundaries (internal implementation details exposed)
• Configuration scattered across multiple locations

Category 3: Test Debt

• Modules with zero test coverage
• Missing integration tests for service boundaries
• Brittle tests (frequently failing, time-dependent, order-dependent)
• Test-code coupling (tests that break on internal refactor, not behavior change)
• Missing E2E tests for critical user flows (from product.md)
• Tests with no assertions (tests that only check "doesn't throw")
• Disabled/skipped tests without justification
• Missing test fixtures or shared test utilities (repeated setup code)

Category 4: Dependency Debt

• Outdated dependencies (>2 major versions behind)
• Known security vulnerabilities (check advisories: npm audit, pip audit, etc.)
• Deprecated APIs in use (check dependency changelogs)
• Version conflicts or pinning issues
• Abandoned dependencies (no updates >2 years, archived repos)
• Overly broad dependency versions (no pinning in production)
• Unnecessary dependencies (functionality available in stdlib or already-included packages)

Category 5: Documentation Debt

• Undocumented public APIs (exported functions/classes without docstrings)
• Stale README (doesn't match current setup steps or architecture)
• Missing architecture decision records for non-obvious choices
• Outdated onboarding documentation
• Missing runbooks for production services
• API docs out of sync with implementation
• Missing inline comments for complex algorithms or business rules

Category 6: Infrastructure Debt

• Manual deployment steps (should be automated)
• Missing or insufficient monitoring (services without health checks or alerts)
• Hardcoded configuration (should be environment variables)
• Missing CI checks (linting, security scanning, type checking)
• No automated backup/restore verification
• Missing or outdated Dockerfiles / container configs
• Inconsistent environment parity (dev/staging/prod divergence)
• Missing rate limiting or resource guards on public endpoints

Category 7: Process Debt ( HLD/LLD compliance)

Scan draft/tracks/*/ for design-process gaps. For each track:

• Read spec.md frontmatter classification.criticality. Default to standard if absent.
• Check for hld.md:
  • Missing for criticality ∈ {standard, high, mission-critical} → flag as Process Debt
  • Severity: critical for mission-critical, high for high, medium for standard
  • Remediation: "Run /draft:decompose <track> to generate hld.md"
• Check hld.md Approvals table:
  • Required rows unsigned (per /draft:upload Step 3.1 logic) and the track has merged commits → flag
  • Severity: high if criticality ∈ {high, mission-critical}, medium otherwise
  • Remediation: "Re-circulate hld.md to listed approvers; update Date column on sign-off"
• Check for lld.md:
  • Any module in HLD §Detailed Design has Complexity: High AND lld.md is missing → flag
  • Severity: medium
  • Remediation: "Run /draft:decompose <track> --lld"
• Check HLD §Checklist completeness:
  • For criticality ≥ standard: any §Checklist sub-section still showing the placeholder text "<Describe..." or empty bullets → flag as Process Debt
  • Severity: high for high/mission-critical, medium for standard
  • Remediation: "Author must populate hld.md §Checklist before /draft:deploy-checklist will pass"
• Check HLD/LLD freshness:
  • If synced_to_commit is older than the latest merged commit touching files in HLD §Detailed Design → flag as drift
  • Severity: medium
  • Remediation: "Run /draft:decompose <track> to refresh graph slots; review structural sections; re-circulate if signed"

Process Debt findings carry the same Impact/Effort/Risk scoring as other categories. They surface in the remediation plan alongside code/architecture debt.

Step 4: Prioritize

For each finding, score on three dimensions:

• Impact (1-5): How much does this hurt development velocity or production reliability?

  • 1: Minor annoyance, cosmetic
  • 2: Slows development occasionally
  • 3: Regular friction, workarounds needed
  • 4: Significant velocity drag or reliability risk
  • 5: Blocking progress or causing incidents

• Risk (1-5): How likely is this to cause a production incident?

  • 1: Extremely unlikely
  • 2: Unlikely but possible
  • 3: Moderate likelihood
  • 4: Likely under certain conditions
  • 5: Near-certain or already causing issues

• Effort (1-5): How much work to remediate?

  • 1: Hours (quick fix)
  • 2: A day or two
  • 3: A sprint (1-2 weeks)
  • 4: Multiple sprints
  • 5: Large project (months)

Priority = (Impact + Risk) / (6 - Effort)

Higher score = higher priority. This formula naturally favors high-impact, low-effort items ("quick wins") and deprioritizes low-impact, high-effort items.

Step 5: Generate Remediation Plan

Organize findings into three actionable tiers:

Tier 1: Quick Wins (Priority > 3, Effort <= 2)

Items that can be fixed in a single sprint or less. Do these first — they deliver the best return on investment.

For each item:

• Specific fix description
• Estimated time (hours)
• Suggested assignee pattern (e.g., "whoever touches this module next")

Tier 2: Strategic Improvements (Priority > 2, Effort > 2)

Items requiring dedicated effort. Create via /draft:new-track or route via /draft:jira (or /draft:plan "tech debt remediation").

For each item:

• Scope and approach
• Estimated effort (sprints)
• Dependencies and sequencing
• Risk of deferral (what happens if we wait?)

Tier 3: Nice-to-Haves (Priority <= 2)

Track but don't prioritize. Revisit quarterly. These items are real debt but the cost of remediation exceeds the current pain.

Step 6: Save Output

MANDATORY: Include YAML frontmatter with git metadata. Follow core/shared/git-report-metadata.md.

Include the report header table immediately after frontmatter:

| Field | Value |
|-------|-------|
| **Branch** | `{LOCAL_BRANCH}` → `{REMOTE/BRANCH}` |
| **Commit** | `{SHORT_SHA}` — {COMMIT_MESSAGE} |
| **Generated** | {ISO_TIMESTAMP} |
| **Synced To** | `{FULL_SHA}` |

Save to: draft/tech-debt-report-<timestamp>.md Create symlink: draft/tech-debt-report-latest.md

TIMESTAMP=$(date +%Y-%m-%dT%H%M)
# Example: draft/tech-debt-report-2026-03-15T1430.md
ln -sf tech-debt-report-${TIMESTAMP}.md draft/tech-debt-report-latest.md

Report structure:

1. Executive Summary — Total findings by category and priority tier, headline stats
2. Priority Matrix — Table of all findings sorted by priority score
3. Category Details — Per-category findings with file locations and evidence
4. Remediation Plan — Three tiers with effort estimates
5. Recommendations — Strategic advice on debt management practices

Report Closing: Next Actions (REQUIRED)

Every tech-debt report must end with a ## Next Actions section listing the smallest set of follow-ups in execution order. Use this exact shape:

## Next Actions

| # | Action | Owner | Blocker? | Skill / Command |
|---|---|---|---|---|
| 1 | <imperative one-liner> | <team\|TBD> | yes/no | `/draft:<skill> <args>` or `n/a` |

Rules:

• Tech-debt rarely "blocks" merge; mark Blocker? = yes only for items that will cause an outage on next deploy.
• Suggest /draft:new-track for items >1 day of work, /draft:adr for design re-decisions, /draft:implement for surgical cleanups.
• Cap at 10 actions; full backlog stays in the report body.

Mandatory Self-Check (before debt report)

Before printing the final debt report, internally verify and report:

1. Graph files queried — JSONL files loaded plus any live graph query-tool invocations (especially cycles and impact).
2. Layer 1 files deliberately skipped — list any context sections skipped as irrelevant to the categories scanned.
3. Filesystem grep fallback justification — for every grep/find run beyond scan-markers.sh, name the concept it searched for.

If draft/graph/schema.yaml does not exist, set Graph files queried: NONE and use justification graph data unavailable.

Graph Usage Report (append to debt report)

Emit the canonical footer from core/shared/graph-usage-report.md §Canonical footer. The lint hook scripts/tools/check-graph-usage-report.sh validates the section on save.

Cross-Skill Dispatch

• Offered by: /draft:new-track (refactor tracks — scope the debt before planning)
• Suggested by: /draft:implement (when TODO/FIXME detected at completion)
• Suggested by: /draft:deep-review (architecture debt findings)
• Feeds into: /draft:jira (or /draft:plan for remediation tracks) (create remediation tickets from Tier 2 items)
• Feeds into: /draft:testing-strategy (Test Debt findings inform test planning)
• Jira sync: If ticket linked, attach report and post summary via core/shared/jira-sync.md

Error Handling

If no draft context: Run with reduced analysis, note: "Run /draft:init for better debt detection with accepted-pattern filtering" If tech-stack.md has accepted patterns: Explicitly skip those patterns, note: "Skipped N accepted patterns from tech-stack.md" If >100 findings: Group by category, show top 20 by priority in the summary, full list in Category Details section If module scope requested but module not found: List available modules, ask user to confirm
