Use when code is CPU-bound and slow,… - [Deadlock Diagnoser](https://agentstack.voostack.com/l/skill-imtiazrayhan-agentscamp-library-deadlock-diagnoser) — Skill · Free · security-reviewed — `agentstack add skill-imtiazrayhan-agentscamp-library-deadlock-diagnoser` Diagnose a database deadlock from the engine's own deadlock report, reconstruct the lock cycle (A holds 1 wants 2, B holds 2 wants 1), name the root cause — almost always two code paths locking the same rows in different orders — and fix it with consistent lock ordering, shorter transactions, and a retry-the-victim safeguard. Use when the DB logs deadlock errors, when transactions intermittently… - [Bundle Analyzer](https://agentstack.voostack.com/l/skill-imtiazrayhan-agentscamp-library-bundle-analyzer) — Skill · Free · security-reviewed — `agentstack add skill-imtiazrayhan-agentscamp-library-bundle-analyzer` Analyze a JS/TS production bundle and surface the biggest size wins — heavy dependencies, duplicate packages, missing code-splitting, oversized polyfills, and dev/server code leaking into the client.

Use when new contributors stru… - [Distributed Tracing Instrumenter](https://agentstack.voostack.com/l/skill-imtiazrayhan-agentscamp-library-distributed-tracing-instrumenter) — Skill · Free · security-reviewed — `agentstack add skill-imtiazrayhan-agentscamp-library-distributed-tracing-instrumenter` Instrument a service (or a chain of services) with OpenTelemetry so a single request can be followed end-to-end — context propagated across every hop including async/queue boundaries, spans at the boundaries that matter, deliberate trace-wide sampling, and trace_id stamped on log lines. Use when latency or failures span multiple services, when you have logs but can't reconstruct a request's full… - [License Compliance Checker](https://agentstack.voostack.com/l/skill-imtiazrayhan-agentscamp-library-license-compliance-checker) — Skill · Free · security-reviewed — `agentstack add skill-imtiazrayhan-agentscamp-library-license-compliance-checker` Audit the licenses of a project's dependencies for compatibility with how the project is distributed — flagging copyleft (GPL/AGPL/LGPL), missing or unknown licenses, and other obligations that conflict with your own license or SaaS/proprietary model.

This is a licensing review,… - [Claude Settings Auditor](https://agentstack.voostack.com/l/skill-imtiazrayhan-agentscamp-library-claude-settings-auditor) — Skill · Free · security-reviewed — `agentstack add skill-imtiazrayhan-agentscamp-library-claude-settings-auditor` Audit every Claude Code settings layer — user, project, local, and managed — and report the effective merged configuration with its risks: over-broad Bash allows, missing deny rules for secrets, bypassPermissions defaults, unvetted MCP servers and hooks, and rules that never match. Use before trusting a new repo's checked-in settings, or to harden your own before handing the agent more autonomy. - [Alerting Rules Tuner](https://agentstack.voostack.com/l/skill-imtiazrayhan-agentscamp-library-alerting-rules-tuner) — Skill · Free · security-reviewed — `agentstack add skill-imtiazrayhan-agentscamp-library-alerting-rules-tuner` Cut alert noise and make every page mean something — rewrite alerting rules to fire on user-felt symptoms (error rate, latency SLO burn, failed requests) instead of causes (high CPU, full disk), with duration windows and severity routing so only urgent, actionable conditions reach a human. Use when on-call is fatigued by low-value pages, when real incidents get missed in the noise, or when alerts… - [Llm Eval Suite Scaffolder](https://agentstack.voostack.com/l/skill-imtiazrayhan-agentscamp-library-llm-eval-suite-scaffolder) — Skill · Free · security-reviewed — `agentstack add skill-imtiazrayhan-agentscamp-library-llm-eval-suite-scaffolder` Stand up an evaluation suite for an LLM feature from scratch — a representative dataset, the right metrics, a baseline score, and a CI gate — using DeepEval, promptfoo, or RAGAS.

Use when RAG answers miss obvious content, when standing up a new corpus, or when picking chunk size/overlap. - [Cors Configurator](https://agentstack.voostack.com/l/skill-imtiazrayhan-agentscamp-library-cors-configurator) — Skill · Free · security-reviewed — `agentstack add skill-imtiazrayhan-agentscamp-library-cors-configurator` Diagnose and fix a failing cross-origin browser request — read the exact console error, work out whether it's a simple or preflighted request, and set the minimal correct Access-Control-* response headers (including the wildcard-with-credentials trap and the OPTIONS preflight) on the server. Use when the browser blocks a fetch/XHR with a CORS error but the API itself works from curl or Postman. - [Auth Flow Reviewer](https://agentstack.voostack.com/l/skill-imtiazrayhan-agentscamp-library-auth-flow-reviewer) — Skill · Free · security-reviewed — `agentstack add skill-imtiazrayhan-agentscamp-library-auth-flow-reviewer` Read-only review of authentication AND authorization flows — session/token model, cookie flags, CSRF, token rotation, password-reset/email-verification, OAuth redirect/state, and per-route object-level access checks — for exploitable gaps. Use before shipping login/session/token code, when adding a protected route or sharing-by-URL feature, or during a security pass. Reports findings by severity… - [Circular Dependency Breaker](https://agentstack.voostack.com/l/skill-imtiazrayhan-agentscamp-library-circular-dependency-breaker) — Skill · Free · security-reviewed — `agentstack add skill-imtiazrayhan-agentscamp-library-circular-dependency-breaker` Detect and break a circular import — map the exact cycle with a real tool, then break the right edge by extracting the shared piece into a leaf module, inverting a layering dependency, merging two falsely-split modules, or (last resort) deferring an import. Use when you hit an import cycle error, an undefined-on-import or 'cannot access before initialization' bug, or a bundler/linter flags a cycl… - [Cold Start Optimizer](https://agentstack.voostack.com/l/skill-imtiazrayhan-agentscamp-library-cold-start-optimizer) — Skill · Free · security-reviewed — `agentstack add skill-imtiazrayhan-agentscamp-library-cold-start-optimizer` Cut cold-start latency for serverless functions and slow-booting apps by measuring the init breakdown, then attacking the dominant phase — artifact size, eager imports, eager connections, or under-provisioned memory — instead of reflexively buying provisioned concurrency. Use when serverless p99 spikes on the first request, when a function times out during init, or when scale-to-zero is hurting u… - [Hook Writer](https://agentstack.voostack.com/l/skill-imtiazrayhan-agentscamp-library-hook-writer) — Skill · Free · security-reviewed — `agentstack add skill-imtiazrayhan-agentscamp-library-hook-writer` Turn a plain-language automation request — 'format every file Claude edits', 'block writes to migrations', 'notify me when input is needed' — into a working Claude Code hook: the right event, a safe tested script, and the settings.json registration at the right scope. Use when you want a hook but don't want to hand-write the matcher, stdin JSON parsing, and exit-code plumbing. - [Dead Code Finder](https://agentstack.voostack.com/l/skill-imtiazrayhan-agentscamp-library-dead-code-finder) — Skill · Free · security-reviewed — `agentstack add skill-imtiazrayhan-agentscamp-library-dead-code-finder` Find genuinely unused code — unreferenced exports, unreachable files, and unused dependencies — and remove it safely with build/test verification. Use when trimming a codebase or untangling years of accreted cruft. - [Github Actions Optimizer](https://agentstack.voostack.com/l/skill-imtiazrayhan-agentscamp-library-github-actions-optimizer) — Skill · Free · security-reviewed — `agentstack add skill-imtiazrayhan-agentscamp-library-github-actions-optimizer` Make a GitHub Actions workflow faster, cheaper, and harder to attack — by profiling where wall-clock and billed minutes actually go, then adding content-keyed caching, matrix/job parallelism, run-cancellation, and path filters, and hardening the supply chain (SHA-pinned actions, least-privilege GITHUB_TOKEN, safe fork-PR handling). Use when CI is slow or queues, when a repo burns Actions minutes,… - [Embedding Index Tuner](https://agentstack.voostack.com/l/skill-imtiazrayhan-agentscamp-library-embedding-index-tuner) — Skill · Free · security-reviewed — `agentstack add skill-imtiazrayhan-agentscamp-library-embedding-index-tuner` Tune a vector index — HNSW graph parameters and quantization — to hit a recall target at the lowest latency and memory, by sweeping settings against a fixed query set instead of trusting defaults. Use when vector search is slow or memory-hungry, when recall dropped after enabling quantization, or when standing up an index and you need defensible parameters. - [Load Test Designer](https://agentstack.voostack.com/l/skill-imtiazrayhan-agentscamp-library-load-test-designer) — Skill · Free · security-reviewed — `agentstack add skill-imtiazrayhan-agentscamp-library-load-test-designer` Design a defensible load test — a realistic workload model, a deliberate test type, and SLO-tied pass/fail thresholds — instead of a meaningless tight-loop script that hammers one endpoint. Use when validating capacity or SLOs before a launch or scaling event, when sizing infrastructure, or when an existing load test reports averages that nobody trusts. - [Llm As Judge Scorer](https://agentstack.voostack.com/l/skill-imtiazrayhan-agentscamp-library-llm-as-judge-scorer) — Skill · Free · security-reviewed — `agentstack add skill-imtiazrayhan-agentscamp-library-llm-as-judge-scorer` Design a reliable LLM-as-judge metric — a calibrated rubric, a clear scoring scale, and bias controls — and validate it against human labels before trusting it. Use when grading open-ended LLM output (summaries, answers, tone) that exact-match can't score. - [Adr Writer](https://agentstack.voostack.com/l/skill-imtiazrayhan-agentscamp-library-adr-writer) — Skill · Free · security-reviewed — `agentstack add skill-imtiazrayhan-agentscamp-library-adr-writer` Write an Architecture Decision Record capturing a decision the user describes, in Michael Nygard ADR format (Status, Context, Decision, Consequences) with an added Considered Alternatives section.

Use when you have raw examples and need a clean, formatted, split dataset before training. - [Graphql Schema Designer](https://agentstack.voostack.com/l/skill-imtiazrayhan-agentscamp-library-graphql-schema-designer) — Skill · Free · security-reviewed — `agentstack add skill-imtiazrayhan-agentscamp-library-graphql-schema-designer` Design a clean, evolvable GraphQL schema (SDL) that won't paint you into a corner — model the graph around domain types and their relationships rather than as RPC-over-GraphQL, set nullability deliberately, standardize lists with Relay connections, plan DataLoader batching for per-parent fields, and evolve by adding + @deprecated instead of versioning. Use when designing a new GraphQL API, review… - [Human In The Loop Gate](https://agentstack.voostack.com/l/skill-imtiazrayhan-agentscamp-library-human-in-the-loop-gate) — Skill · Free · security-reviewed — `agentstack add skill-imtiazrayhan-agentscamp-library-human-in-the-loop-gate` Add a human approval checkpoint to an agent so it pauses before a risky or irreversible action (spending money, deleting data, sending messages, merging code) and resumes only after a human approves. Use when an agent acts autonomously on consequential operations. - [Idempotency Designer](https://agentstack.voostack.com/l/skill-imtiazrayhan-agentscamp-library-idempotency-designer) — Skill · Free · security-reviewed — `agentstack add skill-imtiazrayhan-agentscamp-library-idempotency-designer` Make unsafe, retryable API operations idempotent so a client retry or a network hiccup can't double-charge, double-create, or double-send — design a client-supplied idempotency key, an atomic store-and-check (unique constraint or conditional write), in-flight conflict handling, and a retention policy. Use when a POST/mutation can be retried (payments, order creation, sends, webhooks), or when dup… - [Feature Flag Retirer](https://agentstack.voostack.com/l/skill-imtiazrayhan-agentscamp-library-feature-flag-retirer) — Skill · Free · security-reviewed — `agentstack add skill-imtiazrayhan-agentscamp-library-feature-flag-retirer` Retire stale feature flags by confirming each flag's decided final state, then collapsing every conditional to the winning branch and deleting the loser plus the now-dead code it reached. Use when temporary flags have outlived their rollout, when flag conditionals clutter the code, or during a flag-debt cleanup. - [Embedding Set Inspector](https://agentstack.voostack.com/l/skill-imtiazrayhan-agentscamp-library-embedding-set-inspector) — Skill · Free · security-reviewed — `agentstack add skill-imtiazrayhan-agentscamp-library-embedding-set-inspector` Diagnose the health of an embedding set before blaming the retriever — checking normalization, dimensionality, near-duplicates, degenerate vectors, and corpus/query distribution mismatch. Use when retrieval quality is poor, after a re-embed, or before shipping a new index. - [Architecture Diagram Generator](https://agentstack.voostack.com/l/skill-imtiazrayhan-agentscamp-library-architecture-diagram-generator) — Skill · Free · security-reviewed — `agentstack add skill-imtiazrayhan-agentscamp-library-architecture-diagram-generator` Generate accurate architecture diagrams as Mermaid — straight from the codebase, not from imagination — by first choosing which view answers the question (container/component, sequence, ER, or state) and then reading the real entry points, module boundaries, service calls, and schema. Use when onboarding to an unfamiliar repo, documenting a system, or visualizing one complex flow. - [Git Blame Investigator](https://agentstack.voostack.com/l/skill-imtiazrayhan-agentscamp-library-git-blame-investigator) — Skill · Free · security-reviewed — `agentstack add skill-imtiazrayhan-agentscamp-library-git-blame-investigator` Reconstruct why a line of code exists from Git history — find the originating commit, read its message and full diff for intent, and see through reformatting/rename commits with ignore-revs and the pickaxe — before you change or delete it. Use when a line looks wrong or pointless and you want to remove it, when tracing a regression to its commit, or when onboarding to unfamiliar code. - [Mcp Server Scaffolder](https://agentstack.voostack.com/l/skill-imtiazrayhan-agentscamp-library-mcp-server-scaffolder) — Skill · Free · security-reviewed — `agentstack add skill-imtiazrayhan-agentscamp-library-mcp-server-scaffolder` Scaffold a new Model Context Protocol (MCP) server from a description — pick the SDK and transport, generate a typed first tool with a strict schema, and wire up MCP Inspector testing and the client-registration command. Use when starting a new MCP server and you want a correct, runnable skeleton instead of copying a README. - [Graphrag Scaffolder](https://agentstack.voostack.com/l/skill-imtiazrayhan-agentscamp-library-graphrag-scaffolder) — Skill · Free · security-reviewed — `agentstack add skill-imtiazrayhan-agentscamp-library-graphrag-scaffolder` Stand up a GraphRAG experiment the disciplined way: audit whether your failed queries are actually connection-shaped, scope a minimal entity/relationship ontology, build extraction → graph → community-summary indexing on a corpus slice, and measure against vector-RAG baselines before committing. Use when multi-hop or whole-corpus questions keep failing plain RAG. - [Integration Test Designer](https://agentstack.voostack.com/l/skill-imtiazrayhan-agentscamp-library-integration-test-designer) — Skill · Free · security-reviewed — `agentstack add skill-imtiazrayhan-agentscamp-library-integration-test-designer` Design integration tests that exercise components against REAL collaborators — actual database, queue, HTTP boundary — at a deliberately chosen seam, instead of a unit suite that mocks everything or a slow flaky full E2E. Use when bugs slip past green unit tests, when wiring or contracts between layers break in production, or when a mocked DB test passes but the real query/migration/serialization… - [Llm Guardrails Designer](https://agentstack.voostack.com/l/skill-imtiazrayhan-agentscamp-library-llm-guardrails-designer) — Skill · Free · security-reviewed — `agentstack add skill-imtiazrayhan-agentscamp-library-llm-guardrails-designer` Design input and output guardrails for an LLM app — decide what to check (injection patterns, PII, secrets, policy, schema, leakage, toxicity), place them as input vs. output rails, implement with a library like NeMo Guardrails or LLM Guard, and fail closed. Use when adding a safety/validation layer around an LLM, not relying on the prompt alone. - [Branch Rebaser](https://agentstack.voostack.com/l/skill-imtiazrayhan-agentscamp-library-branch-rebaser) — Skill · Free · security-reviewed — `agentstack add skill-imtiazrayhan-agentscamp-library-branch-rebaser` Rebase the current branch onto its base and walk every conflict methodically, resolving each by understanding both sides.

Use when a service has no dashboard, when the existing one is an unreadable metric wall, or during incident-readiness prep. - [Agent Trajectory Evaluator](https://agentstack.voostack.com/l/skill-imtiazrayhan-agentscamp-library-agent-trajectory-evaluator) — Skill · Free · security-reviewed — `agentstack add skill-imtiazrayhan-agentscamp-library-agent-trajectory-evaluator` Evaluate a multi-step AI agent's whole run — tool calls, intermediate steps, and final result — not just final-answer correctness, so you can pinpoint WHERE it went wrong. Use when building or debugging a tool-using or multi-step agent, when final-answer-only evals can't explain failures, or when a prompt/model change quietly makes the agent less efficient or more error-prone even though the answ… - [Canary Release Planner](https://agentstack.voostack.com/l/skill-imtiazrayhan-agentscamp-library-canary-release-planner) — Skill · Free · security-reviewed — `agentstack add skill-imtiazrayhan-agentscamp-library-canary-release-planner` Design a canary / progressive rollout so a bad release reaches 1% of users instead of 100% — staged traffic with bake times, gating metrics compared against the concurrently-running stable baseline, and automated promote-or-rollback. Use when shipping a risky change, when you want automatic rollback on regression, or when moving off all-at-once deploys. - [Hallucination Evaluator](https://agentstack.voostack.com/l/skill-imtiazrayhan-agentscamp-library-hallucination-evaluator) — Skill · Free · security-reviewed — `agentstack add skill-imtiazrayhan-agentscamp-library-hallucination-evaluator` Detect and measure ungroundedness in LLM and RAG outputs — claims the source doesn't support — by decomposing answers into atomic claims and checking each for entailment, so you can quantify faithfulness and gate on it instead of eyeballing it. Use when a RAG/LLM feature makes confident wrong claims, before shipping anything that must be factual, or to add a groundedness gate to evals/CI. - [Dockerfile Optimizer](https://agentstack.voostack.com/l/skill-imtiazrayhan-agentscamp-library-dockerfile-optimizer) — Skill · Free — `agentstack add skill-imtiazrayhan-agentscamp-library-dockerfile-optimizer` Shrink and harden an existing Dockerfile — multi-stage builds, cache-friendly layer order, a lean pinned base image, a .dockerignore, and a non-root runtime user — without changing what the image runs. Use when an image is too large, builds are slow because the cache never hits, or a scan flags the container running as root. - [Extract Module](https://agentstack.voostack.com/l/skill-imtiazrayhan-agentscamp-library-extract-module) — Skill · Free · security-reviewed — `agentstack add skill-imtiazrayhan-agentscamp-library-extract-module` Split an overgrown file into cohesive, well-bounded modules — find the natural seams, design each new module's public interface before moving a line, then relocate one unit at a time keeping tests green. Use when a file has grown too large, mixes unrelated responsibilities, or every change to it forces unrelated diffs and merge conflicts. - [Contract Test Designer](https://agentstack.voostack.com/l/skill-imtiazrayhan-agentscamp-library-contract-test-designer) — Skill · Free · security-reviewed — `agentstack add skill-imtiazrayhan-agentscamp-library-contract-test-designer` Design consumer-driven contract tests between services so an API provider can't break its consumers unnoticed — without slow, flaky full end-to-end environments. Use when independent services or teams integrate over an API, when integration bugs only surface in staging or prod, or when E2E suites are too slow and brittle to catch breaking API changes. - [Agent Memory Designer](https://agentstack.voostack.com/l/skill-imtiazrayhan-agentscamp-library-agent-memory-designer) — Skill · Free · security-reviewed — `agentstack add skill-imtiazrayhan-agentscamp-library-agent-memory-designer` Design a project's CLAUDE.md and memory hierarchy by exploring the repo to learn its real build/test/lint commands, architecture, and non-obvious gotchas, then writing a concise, skimmable memory that keeps only what belongs in context. Use when onboarding a repo to Claude Code with no CLAUDE.md, or when an existing one is bloated, stale, or being ignored. - [Dependency Upgrade Planner](https://agentstack.voostack.com/l/skill-imtiazrayhan-agentscamp-library-dependency-upgrade-planner) — Skill · Free · security-reviewed — `agentstack add skill-imtiazrayhan-agentscamp-library-dependency-upgrade-planner` Plan and de-risk a major dependency, framework, or runtime upgrade — map the full version path, read every intermediate migration guide, and pin the breaking changes to your actual call sites instead of bumping the number and hoping.
