What it does

Phx Audit is an agent skill from oliver-kriska/claude-elixir-phoenix. Project health audit and health check — architecture, performance; Use when assessing overall project health…

Its SKILL.md is about 1k tokens, which your agent loads only when the skill is triggered. The skill folder holds 3 other files, including reference files (for example `references/architecture-checks.md` and `references/scoring-methodology.md`).

The repository describes itself as: Claude Code plugin for Elixir/Phoenix/LiveView — 26 specialist agents, Iron Laws enforcement, and Tidewave MCP integration. Plan features with parallel research agents, execute… The licence is MIT.

When your agent uses it

  • Assessing overall project health…

Example prompts

  • “/phx-audit”

Workflow steps

4 steps, taken from the first numbered list in SKILL.md.

  1. Complete every selected track before synthesizing — partial results make
  2. Scope each track to concrete directories and checks — vague project-wide
  3. Never compare scores across projects — track trends only within the same
  4. Run quick mode before full mode — catch basic failures before expensive

What it can do on your machine

Read from SKILL.md and the folder at commit 9767a82. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • git

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md. Its commands use git, which can reach the network depending on how they are called.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Phx Audit loads about 1k tokens when it runs, and up to ~3.5k if it reads all its reference files. Until then it costs about 30 tokens; SKILL.md has 417 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~30
When it runs · the whole SKILL.md, loaded when a task matches
~1k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~3.5k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Project Health Audit

Comprehensive project-wide health assessment across five independent concern tracks.

Usage

$elixir-phoenix:phx-audit              # Full audit (default)
$elixir-phoenix:phx-audit --quick      # 2-3 minute pulse check
$elixir-phoenix:phx-audit --focus=security   # Deep dive single area
$elixir-phoenix:phx-audit --focus=performance
$elixir-phoenix:phx-audit --since abc123   # Incremental audit since commit
$elixir-phoenix:phx-audit --since HEAD~10  # Audit last 10 commits

When to Use

  • Quarterly health checks
  • Before major releases
  • After large refactors
  • New team member onboarding (understand codebase health)

Iron Laws

  1. Complete every selected track before synthesizing — partial results make cross-category scores misleading
  2. Scope each track to concrete directories and checks — vague project-wide analysis produces generic findings
  3. Never compare scores across projects — track trends only within the same codebase
  4. Run quick mode before full mode — catch basic failures before expensive analysis

Portable Audit Workflow

  1. Create .claude/audit/reports/ and .claude/audit/summaries/.
  2. Run the quick checks below. Stop and report a blocker when the project cannot compile or its test command cannot start.
  3. Complete five tracks: architecture, performance, security, tests, and dependencies. Native generic workers may run independent tracks in parallel when the runtime provides them; otherwise run every track sequentially in this session. Never require named custom agents.
  4. Write one evidence-focused report per track under .claude/audit/reports/. Report issues only, cite paths and lines, and use one summary line for a clean area.
  5. After all selected reports exist, deduplicate findings, identify cross-category correlations, calculate scores using references/scoring-methodology.md, and write .claude/audit/summaries/project-health-{date}.md.

If two or more optional workers fail or hit limits, finish the missing tracks sequentially. Never present an incomplete track as audited.

Output Format

Report an executive health score, per-category scores for Architecture, Performance, Security, Tests, and Dependencies, critical issues, top recommendations, and an Immediate/Short-term/Long-term action plan.

Show full SKILL.md (172 more words)Show less

Quick Mode (--quick)

Only run essential checks (~2-3 minutes):

Run mix compile --warnings-as-errors, then mix hex.audit && mix deps.audit, then mix xref graph --format stats, then mix test --trace 2>&1 | tail -20.

Skip: Full security scan, N+1 analysis, test quality metrics, architecture deep dive.

Focus Mode (--focus=area)

Run only the selected concern track with its deeper checks:

FocusExtra checks
securityFull OWASP review, Sobelow, manual authorization patterns
performanceQuery plans, N+1 inventory, profiling evidence
architectureFull xref graph, coupling matrix, cohesion
testsCoverage by context, isolation, flaky-test indicators
depsVulnerabilities, licenses, maintenance status

Incremental Mode (--since <commit>)

Analyze only changes since a specific commit. Useful for pre-merge checks:

Run git diff --name-only <commit>...HEAD to identify changed files, then run targeted audits on changed files only (skips full project scan).

Combines with other flags: $elixir-phoenix:phx-audit --since HEAD~5 --focus=security
