Starts, connects to, and troubleshoots a PostHog devbox, a remote Coder workspace for PostHog development that can also run the full stack, through `hogli devbox:*` commands. Use when asked to spin up or resume a devbox, open a shell or editor on it, run a command on it, mirror a local checkout to it (devbox:sync), run the PostHog app on it and share a link, clone, update, share, or free disk on a devbox, store gh or Claude Code tokens for it, or diagnose a failing devbox command (tailnet, DNS, Coder CLI version, SSH). Not for running the stack on the local machine or for changing the Coder template in posthog-cloud-infra.

Resolves a PostHog experiment reference from natural language to a concrete experiment ID by browsing `experiment-list` (not feature-flag tools), with disambiguation when multiple experiments match. Use when the user names or quotes an experiment ("split test demo", "the File engagement boost experiment", "onboarding retention test", "landing page hero experiment", "pricing experiment"), describes it loosely ("the signup experiment", "my pricing test", "the one with the new checkout"), uses a relative reference ("latest", "most recent", "the one I created yesterday"), filters by status (running, draft, paused, exposure frozen, stopped, archived), or otherwise refers to an experiment by anything other than its concrete ID.

Catch the deterministic CI failures reachable from your diff before pushing, with `hogli ci:preflight`. Use when the pre-push hook blocks a push, before reporting a task done, or after editing Python, serializers, migrations, workflows, or dependency manifests — to avoid burning a CI matrix on a failure you could catch locally (formatting, lint, broken lockfiles, OpenAPI drift, migration conflict, stale branch). Trigger terms: ci:preflight, preflight, pre-push checks, pre-push hook failed, "will this break CI".

Triage, verdict, and reply to automated PR review comments from GitHub Copilot and Greptile, then iterate until the bots have nothing left to say. Use this whenever a pull request has feedback from Copilot or Greptile and the user wants those comments handled — e.g. "deal with the bot review comments", "address the Copilot/Greptile feedback on my PR", "go through the review bots", "resolve the automated review", or after pushing a branch and asking to "clear the AI reviewers". It judges each comment on its merits (fixing real issues, pushing back on nitpicks), replies inline on each thread, commits and pushes fixes, re-requests review from both bots, waits for the fresh round, and repeats until clean.

Write B2B cold emails and follow-up sequences that get replies. Use when the user wants to write cold outreach emails, prospecting emails, cold email campaigns, sales development emails, or SDR emails. Covers subject lines, opening lines, body copy, CTAs, personalization, and multi-touch follow-up sequences.

Audit, design, and migrate Identity and Access Management — cloud provider IAM (AWS, GCP, Azure), identity providers (Okta, Entra ID / Azure AD, Auth0, Google Workspace), application authorization (RBAC, ABAC, ReBAC), and federated identity. Use when the user mentions 'IAM,' 'identity,' 'access management,' 'least privilege,' 'role design,' 'SSO,' 'SAML,' 'OIDC,' 'OAuth,' 'JIT access,' 'just-in-time access,' 'break-glass,' 'service accounts,' 'RBAC,' 'ABAC,' 'privilege creep,' 'role explosion,' 'identity governance,' 'IAM strategy,' 'identity migration,' 'Okta,' 'Entra ID,' 'Azure AD,' 'Auth0,' 'Cognito,' or needs identity consultant-level guidance.

Audit container images, Dockerfiles, and Kubernetes manifests for misconfigurations, excessive privileges, exposed secrets, and runtime risks. Use when the user mentions 'container security,' 'Docker security,' 'Dockerfile audit,' 'Kubernetes security,' 'K8s security,' 'pod security,' 'container hardening,' 'kubectl audit,' 'image scanning,' 'distroless,' 'rootless containers,' 'pod security policy,' 'pod security standards,' 'PSS,' 'network policy,' 'OPA Gatekeeper,' 'Kyverno,' 'runtime security,' or needs to review container or orchestration security.

Run an ASI-Evolve style evaluator-driven search workflow for code, algorithms, prompts, or pipelines. Use when Claude needs to align the objective, scoring, evaluator, writable scope, and cognition first, then execute a preflight-gated learn/design/experiment/analyze loop with the bundled Evolve CLI instead of the repository's multi-agent pipeline.

Resolve Git merge conflicts by extracting only unresolved paths, conflict hunks, and compact diffs instead of loading whole files into context. Use when a merge, rebase, cherry-pick, or stash pop stops on conflicts, when `git status` shows unmerged paths, or when files contain conflict markers.

Set up and run mutation testing with PIT (pitest) on a Gradle project, and read the mutation score. Use this skill whenever the user wants mutation testing added to a build, configured, run or re-run, wants a mutation score or a mutation report interpreted, asks why a particular mutant survived, or asks what should be excluded from mutation analysis, or wants something added to those exclusions — in any language, and whether or not the tool is named. Also use it when the task calls for it: checking test quality rather than coverage — a high JaCoCo number can hide tests that assert nothing.

Reformat source code in this project using its own code-style settings — through the IntelliJ IDE when it's running, otherwise via the project's own formatter (Spotless / google-java-format / palantir-java-format) as a fallback. Use this whenever the user asks to format, reformat, tidy, "prettify", fix indentation, or optimize imports on Java/Kotlin/XML/etc. files — whether it's a single named file, a selected block or line range, a group of named files, or all uncommitted (git-changed) files. This skill is also normally invoked after any editing of files — apply it to the files you just created or changed once the edits are done, so the result stays consistent with the project's code style.

Daily radar over the Vikunja board: scan open tasks and surface the ONE most valuable signal (overdue urgent task, stuck priority, decision that unblocks others, quick win, imminent deadline) as a short actionable nudge - or stay silent when nothing deserves attention. Read-only. Use when the user asks 'what should I work on', 'anything urgent?', 'morning briefing', 'task pulse', or on a schedule via claude -p.

Advance a long-horizon project by exactly one CID-loop iteration (update-state → define-next → advance → review), with rigor adjusted to the project's current phase (new/poc/mvp/stable). Use when explicitly asked to "run the build loop", "advance the project", "run one CID iteration", on /long-horizon:build, or when an automation (/goal, /loop, a scheduled task) drives autonomous building. Requires a CID context pack at .cid/ (create one with /long-horizon:init). NOT for one-off edits, questions, or reviewing unrelated work.

Archive irreplaceable raw data (sequencing runs, imaging, field data) to write-once cloud cold storage — generate checksums, verify before upload, stream a tarball to S3 Deep Archive under Object Lock, and prove the pipeline with a restore test before trusting it at scale. Use when the user asks to back up or archive raw data, set up an immutable/WORM backup, generate md5 checksums for a data folder, or verify/restore an existing archive.

Add provenance frontmatter to every .md file Claude creates. MUST activate whenever Claude uses the Write tool to create a NEW .md file. Ensures every Claude-generated markdown file has frontmatter recording authorship, creation date, purpose, context provided, and source references. Does NOT apply when editing existing files or writing non-.md files.

Keeps a long Claude Code task on-track — breaks out of looping/circular thinking, watches the context budget, bounds internal reasoning, and triggers a clean handoff before the window fills. Use when the model is repeating steps, re-reading the same files, second-guessing in circles, stuck or spinning, or running a long multi-step task at risk of exhausting context. Also use when the user says it is "looping", "going in circles", "stuck", "repeating itself", or asks for a handoff before running out of context.

Write self-contained implementation plan files that a fresh, possibly weaker executor can run without the author's context — splitting work into PR-sized plans, with verification gates, STOP conditions, and a memo protocol for design forks. Use when asked to write/create a plan, turn a decided design or ticket into plans, or when another skill hands off plan-writing. Not for deciding what to build or executing plans.

Use when the user asks to create, generate, visualize, or turn material into a standalone HTML artifact, self-contained or single-file .html report, interactive explainer, interactive illustration or visualization, visual walkthrough or handoff, or HTML presentation or slide deck. Handles source-grounded codebase and architecture, feature, PR or diff, implementation recap, incident timeline, option comparison, causal, and data-report explanations. Not for prose-only analysis or reviews, production web apps or dashboards, websites, HTML email, or ordinary frontend/UI implementation.

Build evidence-backed software/product roadmaps from repo state, tickets, ideas, audit findings, or user goals — prioritize and sequence work across Now/Next/Later, milestones, dependencies, risks, and handoffs. Use when asked for a roadmap, feature roadmap, technical roadmap, release plan, milestone plan, backlog prioritization, sequencing, what to build next, or to turn improve/ideate/brainstorm/design-discussion outputs into an execution sequence. Not for implementing code or writing PR-level plans.

DEPRECATED - this skill is unmaintained. Use the official Angular skills at https://github.com/angular/skills instead. Create custom directives in Angular v20+ for DOM manipulation and behavior extension. Use for attribute directives that modify element behavior/appearance, structural directives for portals/overlays, and host directives for composition. Triggers on creating reusable DOM behaviors, extending element functionality, or composing behaviors across components. Note - use native @if/@for/@switch for control flow, not custom structural directives.
