Existing Phoenix/LiveView UI and frontend work: HEEx/components, styling, assets, browser behavior, runtime UI feedback, PhoenixReplay, Volt, icons, Tailwind, and interactive verification. Use instead of elixir when UI/frontend behavior is the primary task; not for project creation.
Existing Elixir application/library development and debugging. Use for .ex/.exs, Mix, OTP, Ecto, backend Phoenix, dependencies, docs, tests, or BEAM runtime state. Use elixir-web instead when the primary task is UI/LiveView/frontend work, and elixir-new-project instead for creation/bootstrap.
Guides use of the debugstate tool and runtime introspection to diagnose agent issues between turns. Load this skill when something goes wrong during a session and you need to inspect agent state, token usage, event history, or tool availability.
Detects and removes cyclic compile-time dependencies in Elixir codebases using mix xref, with minimal code changes. Use when the user explicitly asks to check for cycles, remove cyclic dependencies, or fix xref cycle failures. Requires Elixir 1.19 or higher for accurate results.
Writes live integration tests that hit the real Copilot API and record responses as replayable fixtures. Use this skill when adding new agent behaviors, provider integrations, or tool interactions that need real-world API coverage.
Conduct deep, multi-source research on technologies, companies, markets, and topics — synthesizing findings into structured reports with citations and actionable insights.
Use when implementing Phoenix LiveView features - TDD with htmlsnapshot for state inspection and axe-core for accessibility. Sprinkle snapshots to see what's rendered, delete when done.
Fetch repository information from GitHub, including trending project search and repository detail lookup. Use this skill when you need GitHub project information.
Fetch web content from a URL, supporting plain-text extraction and raw HTML output. Use this skill when you need to retrieve information from websites.
Use when a Codex CLI/Desktop root should fan out subagents, delegate to Pixir workers, run parallel workers, or manage a resident delegation daemon via Pixir Delegate; covers Codex preflight, AGENTS.md, approvals/sandbox, dry-run, daemon start/status/attach/cancel, closure evidence, and audited single-run execution…
Use Pixir as a headless subagent runtime from Claude Code or any harness with skill ! preprocessing (Codex roots and other no-hydration hosts use pixir-delegate-codex instead) — one-shot workers (pixir --json), parallel fan-out to N children (pixir delegate --spec), resumable steering (pixir resume), evidence…
Diagnose Pixir and T3 Code Pixir incidents from local canonical evidence. Use when a Pixir run, ACP/T3 thread, subagent/workflow, provider replay, or daily-driver dogfood session appears stuck, inconsistent, missing tool output, or hard to classify.
Verify AI agent code for dangerous patterns including infinite loops, unbounded retries, tool hallucinations, and context overflow. Use before deploying agent workflows or when reviewing agent code.
