--- name: application-risk-and-technical-debt-identifier description: "Converts application portfolio metadata into a prioritized risk register that scores each application across six technical debt dimensions, flags hotspots, assigns remediation urgency tiers, and delivers a sequenced remediation roadmap with quick wins and strategic bets. Use when auditing an application portfolio, identifying technical debt hotspots, prioritizing modernization or remediation work, or building a risk register for engineering leadership." argument-hint: "[application-metadata] [portfolio-size]" allowed-tools: ["Read"] --- # Application Risk and Technical Debt Identifier ## Purpose Turn raw application metadata (age, language, dependency count, test coverage, deployment frequency, support burden) into a prioritized risk register that pinpoints technical debt hotspots and tells leadership exactly which applications to remediate first and why. Replaces gut-feel modernization debates with a defensible, scored ranking. ## When to Use Invoke this skill when the user asks to: - Audit an application portfolio for risk and technical debt - Identify which applications are the biggest technical debt hotspots - Prioritize modernization, refactoring, or remediation work across many apps - Build a risk register for engineering or architecture leadership - Justify a modernization budget or decommission decision with data - Assess whether a legacy application should be maintained, refactored, or retired ## Inputs Required Before starting, collect: - **Application list**: Each application by name, ideally with a one-line description of its business function - **Age / last major rewrite**: Years since build or last significant modernization, per app - **Language / framework and version**: Primary stack and whether the version is current, in support, or end-of-life - **Dependency count and staleness**: Number of dependencies and how many are outdated or unsupported (if known) - **Test coverage**: Approximate automated test coverage percentage, or "none/unknown" - **Deployment frequency**: How often the app ships (per day / week / month / rarely) - **Support burden**: Incident volume, on-call load, or maintenance hours per month - **Business criticality**: Revenue impact or tier (mission-critical / important / peripheral) If test coverage, dependency staleness, or business criticality is unknown for an app, score it conservatively (assume higher risk) and flag the missing data as a data-quality gap in the output. ## Instructions ### Step 1: Score Each Application Across Six Risk Dimensions For every application, assign a 1–5 score per dimension (1 = healthy, 5 = critical risk). Use these calibration anchors: **Dimension 1 — Stack Currency** - 1: Current, actively supported language/framework version - 3: One major version behind or approaching end-of-support - 5: End-of-life stack, no security patches, or unsupported runtime **Dimension 2 — Test Safety Net** - 1: >70% coverage with CI gates - 3: 30–70% coverage or partial automation - 5: <10% coverage, manual-only, or unknown **Dimension 3 — Dependency Health** - 1: Few dependencies, all current - 3: Moderate count with some outdated packages - 5: Heavy dependency graph with unsupported or vulnerable packages **Dimension 4 — Change Velocity** - 1: Ships frequently (weekly+), low friction - 3: Ships monthly, moderate friction - 5: Rarely ships or deploys are high-risk manual events (fear-to-touch code) **Dimension 5 — Support Burden** - 1: Low incident volume, minimal on-call impact - 3: Recurring incidents or noticeable maintenance drag - 5: Frequent incidents, high on-call load, or firefighting mode **Dimension 6 — Age / Architectural Drift** - 1: Recently built or modernized (<3 years) - 3: 3–7 years, some architectural erosion - 5: 8+ years, no major rewrite, accumulated architectural drift ### Step 2: Calculate Composite Risk Score - Sum the six dimension scores into a **Raw Risk Score** (range 6–30). - Multiply by a business-criticality weight: mission-critical ×1.5, important ×1.2, peripheral ×1.0. - Record the resulting **Weighted Risk Score** — this drives ranking. Rationale: a broken peripheral tool matters less than a fragile revenue system. ### Step 3: Assign Remediation Urgency Tiers Map each weighted score to a tier: - **Tier 1 — Critical (act this quarter)**: Weighted score ≥ 30, OR any single dimension = 5 on a mission-critical app (especially Stack Currency or Dependency Health with security exposure) - **Tier 2 — High (plan within 6 months)**: Weighted score 20–29 - **Tier 3 — Monitor (track, no immediate action)**: Weighted score 12–19 - **Tier 4 — Healthy (maintain as-is)**: Weighted score < 12 ### Step 4: Identify Technical Debt Hotspots Beyond scores, flag structural patterns across the portfolio: - **Fear-to-touch apps**: High age + low test coverage + rare deploys (dimensions 2, 4, 6 all high) — the most dangerous debt because it compounds silently - **Security time bombs**: End-of-life stack or unsupported dependencies on any internet-facing or mission-critical app - **Support sinks**: High support burden dragging engineering capacity away from roadmap work - **Concentration risk**: Multiple critical apps sharing the same end-of-life stack — a single dependency failure could cascade ### Step 5: Recommend Remediation Strategy Per Tier 1 and Tier 2 App For each Tier 1 and Tier 2 application, recommend one action and a rationale: - **Refactor / modernize in place**: High business value, salvageable architecture - **Rewrite / replatform**: High value but architecturally unsalvageable - **Rehost / patch and stabilize**: Buys time while a longer decision is made - **Decommission / consolidate**: Low value, high burden — retire or fold into another system - **Increase test coverage first**: When the app is high-value but too risky to touch until a safety net exists ### Step 6: Sequence the Roadmap Produce a prioritized sequence: - **Quick wins (0–90 days)**: Low-effort, high-risk-reduction items — dependency upgrades, adding CI gates, patching end-of-life runtimes - **Strategic bets (3–12 months)**: High-effort modernization or replatform work on Tier 1 mission-critical apps - **Sequencing logic**: Address security time bombs and concentration risk before elective modernization; build test coverage on fear-to-touch apps before refactoring them ## Output Format - **Structure**: A risk register table (all apps, sorted by Weighted Risk Score descending) followed by hotspot callouts, per-app remediation recommendations for Tier 1/2, and a sequenced roadmap - **Length**: 900–1,400 words plus the register table (scales with portfolio size) - **Format**: Table for the register; structured bullets for hotspots and roadmap - **Sections**: Risk Register Table → Urgency Tier Summary → Technical Debt Hotspots → Remediation Recommendations (Tier 1 & 2) → Sequenced Roadmap (Quick Wins / Strategic Bets) → Data-Quality Gaps - **Tone**: Enterprise architect briefing engineering leadership — analytical, decisive, and cost-of-inaction aware. No hedging on rankings. ## Quality Checklist Before delivering output, verify: - [ ] Every application received all six dimension scores (1–5) — none skipped - [ ] Weighted Risk Score is computed with the business-criticality multiplier applied - [ ] The register table is sorted by Weighted Risk Score, highest first - [ ] Every app is assigned exactly one urgency tier consistent with its score and the tier thresholds - [ ] Each Tier 1 and Tier 2 app has a specific remediation strategy and rationale — not just "modernize" - [ ] Any app with missing input data is flagged in the Data-Quality Gaps section and scored conservatively ## Notes - The most dangerous debt is rarely the oldest app — it's the high-criticality app with no test safety net that nobody wants to touch. Weight the ranking toward compounding risk, not just age. - Concentration risk (many apps on one dying stack) is easy to miss when scoring apps individually — always scan the portfolio horizontally for shared end-of-life dependencies. - Recommend that decommission candidates be validated with a usage audit before retirement — "peripheral" apps sometimes hide critical downstream consumers. - Quick wins first builds leadership confidence and frees engineering capacity to fund the strategic bets — sequence accordingly. --- ## How to use this skill This file is a Claude Code skill in [Anthropic's standard format](https://docs.anthropic.com/en/docs/claude-code/skills) — markdown with YAML frontmatter at the top. **Installing in Claude Code:** - `~/.claude/skills//SKILL.md` — auto-loads in every session anywhere on your machine (recommended for skills you'll use across multiple projects) - `/.claude/skills//SKILL.md` — auto-loads only when working in that project (recommended for project-specific skills) Restart Claude Code or open a new session to register. **Using in Claude.ai, ChatGPT, Gemini, or other AI tools:** 1.
