Guide for creating, updating, and deprecating hybrid cloud RPC services in Sentry. Use when asked to "add RPC method", "create RPC service", "hybrid cloud service", "new RPC model", "deprecate RPC method", "remove RPC endpoint", "cross-silo service", "cell RPC", or "control silo service". Covers service scaffolding, method signatures, RPC models, cell resolvers, testing, and safe deprecation workflows.

When the user wants to reduce churn, build cancellation flows, set up save offers, recover failed payments, or implement retention strategies. Also use when the user mentions 'churn,' 'cancel flow,' 'offboarding,' 'save offer,' 'dunning,' 'failed payment recovery,' 'win-back,' 'retention,' 'exit survey,' 'pause subscription,' or 'involuntary churn.' This skill covers voluntary churn (cancel flows, save offers, exit surveys) and involuntary churn (dunning, payment recovery). For post-cancel win-back email sequences, see email-sequence. For in-app upgrade paywalls, see paywall-upgrade-cro.

Run an application-wide, read-only architecture audit that finds materially useful simplifications in a codebase's data structures, state representation, control flow, algorithms, and ownership boundaries. Fans out bounded read-only agents per subsystem, verifies every finding against the repo, and ranks results P0 to P3. Use when asked to audit architecture, review how state or data is modelled, find structural simplifications, or invoke /audit-architecture. Not a style or line-level quality pass (use /simplify for that) and not a bug hunt (use /code-review).

Scan all project dependencies for known vulnerabilities using Software Composition Analysis. Use when the user says "scan my dependencies", "SCA scan", "vulnerable dependencies", "endor sca", "what's wrong with my deps", or wants a focused dependency vulnerability report with direct vs transitive breakdown. Do NOT use for checking a single package (/endor-check), SAST code scanning (/endor-sast), or quick full scan (/endor-scan).

Fast security scan of the current repository using Endor Labs. Use when the user says "scan my code", "quick scan", "endor scan", "scan this repo", "run a security scan", or wants a rapid overview of vulnerabilities, secrets, and SAST issues. Also handles incremental PR scans when user mentions "just my changes" or "PR scan". Do NOT use for deep reachability analysis (/endor-scan-full) or checking a single package (/endor-check).

Create and manage Endor Labs security policies for automated enforcement. Use when the user says "create a policy", "block critical vulns", "endor policy", "security gate", "enforcement rules", "exception policy", or wants to define rules for blocking PRs, requiring reviews, or enforcing security standards. Do NOT use for one-time PR review (/endor-review) or viewing findings (/endor-findings).

Scan container images and analyze Dockerfiles for security issues. Use when the user says "scan my Docker image", "Dockerfile security", "container scan", "endor container", "docker compose security", or is creating/modifying Dockerfiles and docker-compose files. Checks for root user, latest tags, exposed ports, secrets in build args, and missing health checks. Do NOT use for application code scanning (/endor-sast).

Remove background noise and isolate vocals/speech from audio using ElevenLabs Voice Isolator (audio isolation) API. Use when cleaning up noisy recordings, removing music or background ambience from dialogue, isolating speech from field recordings, preparing audio for transcription, extracting vocals, or any "denoise / clean up / isolate voice" task.

Use when a dd-trace-js change introduces or substantially changes a class hierarchy, module boundary, shared helper layer, public API, or duplicated behavior across multiple types. Triggers: architecture decision, design review, refactor shared behavior, new abstraction, composition versus inheritance, expose internals, module coupling, public surface, hot-path architecture, score the design.

Develop and deploy Lakeflow Jobs on Databricks via DABs, Python SDK, or the CLI. Use when creating data engineering jobs with notebooks, Python wheels, SQL, dbt, or pipelines. Invoke BEFORE starting implementation.

Use when an n8n-mcp account targets more than one n8n instance — i.e. the `n8n_instances` tool is available, the user mentions multiple n8n instances or environments (prod vs staging, several teams or clients), a workflow / datatable / credential / execution call returns an unexpected NOT_FOUND or reads data you don't recognize, or a credential create/update/delete is refused with an `INSTANCE_AMBIGUOUS` error. Covers choosing and switching which instance this MCP session targets, verifying the target before high-stakes work — credential writes above all — and recovering from misroutes and ambiguous-write fail-closes. Always consult this skill before operating on a specific instance, before any credential create/update/delete on a multi-instance account, or when a call hits the wrong/empty data or an `INSTANCE_AMBIGUOUS` error.

Operating manual for the Lineth Stack quickstart — the Docker-Compose dev/demo stack at docs/getting-started/lineth-stack in the lineth-monorepo that boots a local Linea/Lineth L2 with Sepolia or local L1 finality. Use whenever you are working inside the lineth-stack quickstart and need to boot or run the stack, choose between local and Sepolia L1 mode, get past the Sepolia deployer-funding step, read the finality/success signals, run traffic or bridge smoke tests, reset it, or debug a failing boot (L1 RPC unreachable, deploy gas too low, unfunded deployer, port collision, prover out-of-memory, address mismatch, finality not advancing). Trigger even on casual asks — "start the stack", "run the quickstart", "boot lineth locally", "my deploy keeps failing", "finality isn't happening", "reset the quickstart". When editing this package's scripts or docs, also read rules/making-changes.md so commits pass the repo's lint and DCO gates.

Connect Claude to external apps like Gmail, Slack, GitHub. Use this skill when the user wants to send emails, create issues, post messages, or take actions in external services.

Automate Aeroleads tasks via Rube MCP (Composio). Always search tools first for current schemas.

Creates and updates pull requests and merge requests for cloudflare-docs changes. Covers title conventions, branch naming, request body structure, and documentation checklist templates. Load when asked to open, create, submit, update, or edit a PR or MR, or write a PR or MR title or description.

Extract brand identity (fonts, colors, typography, spacing, favicons) from any URL and install fonts in an AEM Edge Delivery Services project via Adobe Fonts (Typekit) or Google Fonts. Detects fonts using 4 browser API layers (document.fonts, CSS import-rule walk, Performance API, computed style voting), then resolves via a 5-step cascade: system font, Typekit kit match, Adobe Fonts add-to-kit, Google Fonts fallback, or not-found. Updates head.html with font embed tags. Use when starting a site migration, setting up an EDS project, or extracting a site's visual identity. Triggers on: brand setup, brand extract, brand fonts, install fonts, configure brand.

Persist and resume Claude Code session progress across restarts, --resume/--continue, and context compaction. Use when asked to persist/save/output session state, or when starting a session and checking for prior progress to resume from.

Use when adding support for a new event or metric in the analytics exporter at zeebe/exporters/analytics-exporter/ — creating handlers, adding AnalyticsAttributes, registering in the HandlerRegistry, and writing tests. Also use when modifying existing handlers or attributes.

Audit cryptography implementation — algorithm choice, key sizes, KDF parameters, IV/nonce handling, signature verification, randomness, TLS configuration, and key rotation. Deeper than owasp-audit A02. Use when the user mentions 'crypto review,' 'cryptography audit,' 'encryption review,' 'KDF,' 'PBKDF2,' 'Argon2,' 'bcrypt cost,' 'IV reuse,' 'nonce reuse,' 'AES mode,' 'AES-GCM,' 'AES-ECB,' 'signature verification,' 'TLS configuration,' 'cipher suites,' 'key rotation,' 'libsodium,' 'BoringSSL,' or 'is this crypto right.'
