What it does
Tech Debt Tracker is an agent skill from borghei/Claude-Skills. Scan codebases for technical debt with AST parsing, prioritize by impact, and generate trend dashboards. Use when tracking tech debt, prioritizing refactoring, calculating cost-of- delay, planning sprint debt, or reporting debt to execs.
Its SKILL.md is about 1.9k tokens, which your agent loads only when the skill is triggered. The skill folder holds 26 other files, including scripts, reference files and assets (for example `README.md`, `REFERENCE.md` and `assets/historical_debt_2024-01-15.json`).
It sits in Development, covering Technical debt. The repository describes itself as: 385 AI skills, 77 expert agents, and 900 stdlib Python tools for every team: engineering, PM, marketing, C-level, compliance, business ops, research, and a LinkedIn toolkit… The licence is MIT.
When your agent uses it
- Tracking tech debt
- Prioritizing refactoring
- Calculating cost-of- delay
- Planning sprint debt
Example prompts
- “/tech-debt-tracker”
Requirements
- Python 3
- Node.js
What it can do on your machine
Read from SKILL.md and the folder at commit c9a1487. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Ships 1 file in scripts/ (Python and JavaScript, from the files we listed), which the agent can run.
Shell commands in SKILL.md call:
python
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Tech Debt Tracker loads about 1.9k tokens when it runs, and up to ~15k if it reads all its reference files. Until then it costs about 64 tokens; SKILL.md has 794 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); the scripts in this folder are not scanned.

Tech Debt Tracker
The agent identifies, scores, prioritizes, and tracks technical debt across codebases using AST parsing, cost-of-delay analysis, and trend dashboards.
Core Capabilities
- Detection — AST parsing (Python) and regex pattern matching (all languages) across six debt categories: code, architecture, test, documentation, dependency, infrastructure.
- Severity scoring — rate each item on velocity, quality, productivity, and business impact (1-10) plus effort sizing (XS-XL) and risk.
- Cost-of-delay — compute interest rate (
Impact x Frequency) and cost of delay (Interest x Sprints x Team Multiplier); also WSJF and RICE frameworks. - Prioritization — plot on the Cost-of-Delay vs Effort matrix (Immediate / Planned / Opportunistic / Backlog).
- Sprint allocation — apply the Debt-to-Feature ratio by team velocity; reserve capacity for debt work.
- Refactoring strategies — Strangler Fig, Branch by Abstraction, Feature Toggles, Parallel Run.
- Reporting — executive and engineering dashboards, trend analysis, velocity tracking, and forecasts from scan snapshots.
When to Use
- Tracking and quantifying technical debt across a repository.
- Prioritizing refactoring work and calculating cost-of-delay.
- Planning sprint capacity allocation between debt and features.
- Reporting debt health, trends, and investment recommendations to execs.
Clarify First
Before scanning or reporting, confirm these inputs. If any is unknown or vague, ASK — do not assume:
- Target codebase — the directory to scan (the subject of the debt inventory)
- Prioritization framework & team size — cost-of-delay / WSJF / RICE and headcount (
--framework,--team-size; changes the ranking and sprint allocation) - Report audience — exec dashboard vs engineering inventory (sets the report format and altitude)
Stop rule: ask only the 2-3 that most change the output. If the user says "just draft it," proceed and list your assumptions at the top of the artifact.
Tools
| Tool | Purpose | Command |
|---|---|---|
debt_scanner.py | Scan a directory for debt signals; output JSON inventory + text report | python scripts/debt_scanner.py <dir> --output scan_results --format both |
debt_prioritizer.py | Enrich inventory with cost-of-delay/WSJF/RICE and sprint allocation | python scripts/debt_prioritizer.py scan_results.json --framework wsjf --team-size 8 |
debt_dashboard.py | Trend analysis, velocity, forecasts, and exec summary across snapshots | python scripts/debt_dashboard.py --input-dir ./debt_scans/ --period quarterly |
References
Load the reference that matches the task — keep this file lean and pull detail on demand:
- references/methodology.md — the 7-step workflow, debt-classification table, severity scoring framework, interest-rate/cost-of-delay formulas, prioritization matrix, WSJF, sprint allocation ratios, the debt-item JSON schema, refactoring strategies, and quarterly planning. Read when scoring, prioritizing, or planning.
- references/tool-reference.md — full parameter tables, examples, and output-format details for all three scripts plus the troubleshooting table. Read when running the scripts or debugging output.
- references/dashboards-and-examples.md — executive and engineering dashboard layouts, a worked Python-microservice scan example, and the success-criteria bar. Read when generating reports or validating quality.
- references/debt-classification-taxonomy.md — comprehensive taxonomy for classifying debt across dimensions with detection heuristics per category. Read when calibrating detection or labeling items.
- references/prioritization-framework.md — deep prioritization approaches based on business value, risk, effort, and strategic alignment. Read when designing a prioritization rubric.
- references/stakeholder-communication-templates.md — templates and guidelines for communicating debt status, impact, and recommendations to different stakeholder groups. Read when reporting to execs or product.

Scope & Limitations
This skill covers:
- Static detection of code-level, architecture, test, documentation, dependency, and infrastructure debt via AST parsing (Python) and regex pattern matching (all languages).
- Quantitative prioritization of debt items using cost-of-delay, WSJF, and RICE frameworks with configurable team size and sprint capacity.
- Historical trend analysis, health scoring, debt velocity tracking, and executive/engineering dashboard generation from multiple scan snapshots.
- Sprint allocation planning with capacity-aware backlog scheduling and effort estimation by debt type.
This skill does NOT cover:
- Runtime performance profiling or production monitoring -- see
engineering/performance-profilerandengineering/observability-designerfor those concerns. - Dependency vulnerability scanning (CVE detection) or software composition analysis -- see
engineering/dependency-auditorfor security-focused dependency review. - Automated refactoring or code transformation -- the skill identifies and prioritizes debt but does not modify source code.
- Database schema debt, API contract drift, or infrastructure-as-code drift detection -- see
engineering/database-schema-designer,engineering/api-design-reviewer, andengineering/migration-architectfor those domains.
Integration Points
| Skill | Integration | Data Flow |
|---|---|---|
engineering/dependency-auditor | Feed dependency audit findings into the scanner as dependency_debt items to unify all debt in one inventory. | Dependency audit JSON -> scanner config or manual merge into debt_inventory.json |
engineering/performance-profiler | Correlate performance hotspots with high-complexity debt items to prioritize refactoring that yields both quality and speed gains. | Profiler hotspot report -> cross-reference with scanner output by file path |
engineering/ci-cd-pipeline-builder | Add debt_scanner.py as a CI pipeline step to fail builds when health score drops below a threshold or critical debt count increases. | Scanner JSON output -> CI gate condition on summary.health_score |
engineering/pr-review-expert | Surface relevant debt items during code review by querying the debt inventory for files touched in a pull request. | PR changed-files list -> filter debt_inventory.json by file_path |
engineering/observability-designer | Map infrastructure debt items (missing monitoring, env inconsistencies) to observability gaps identified by the observability skill. | Dashboard category_distribution -> observability gap analysis |
engineering/migration-architect | Use the prioritized backlog to scope and sequence large-scale migration efforts, especially for architecture-category debt rated as planned initiatives. | Prioritizer sprint_allocation -> migration planning timeline |
