  • Works in 4 steps: Gather Context → Classify Intent → Respond or Clarify → …

  • SKILL.md covers Usage, Arguments, Execution Flow and Iron Laws, plus 1 more section
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md

What it does

Phx Help is an agent skill from oliver-kriska/claude-elixir-phoenix. Use when the user asks which phx- command fits a task (review, plan, debug, test) or how two commands differ. Checks plans and git state, then recommends from the routing table. Not for bare /help, a tour, or ambiguous requests (intent-detection).

Its SKILL.md is about 1.1k tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including reference files (for example `references/tool-catalog.md`).

It sits in Development. It works with Git. 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

  • The user asks which phx- command fits a task (review
  • How two commands differ

Example prompts

  • “/phx-help”

Workflow steps

4 steps, taken from the step headings in SKILL.md.

  1. Gather Context
  2. Classify Intent
  3. Respond or Clarify
  4. Offer Follow-up

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

    No scripts in the folder and no shell commands in SKILL.md.

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

  • Network

    No URLs in SKILL.md.

    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 Help loads about 1.1k tokens when it runs, and up to ~3.5k if it reads all its reference files. Until then it costs about 64 tokens; SKILL.md has 497 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~64
When it runs · the whole SKILL.md, loaded when a task matches
~1.1k
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.

name
phx-help
description
Use when the user asks which phx-* command fits a task (review, plan, debug, test) or how two commands differ. Checks plans and git state, then recommends from the routing table. Not for bare /help, a tour, or ambiguous requests (intent-detection).

Plugin Help — Interactive Command Advisor

Helps users find the right command, skill, or agent for their situation.

Usage

phx-help                          # Analyze context, suggest commands
phx-help how do I debug this?     # Route to phx-investigate
phx-help add a new feature        # Route to phx-plan -> phx-work

Arguments

  • $ARGUMENTS — optional description of what the user wants to do
  • Empty = analyze current context (git status, existing plans, file patterns)

Execution Flow

Step 1: Gather Context

If $ARGUMENTS is non-empty, use it as primary signal.

Always gather ambient context (run in parallel):

  1. Check for existing plans: use Glob on .claude/plans/*/plan.md — active work in progress?
  2. Check git status: uncommitted changes? which files?
  3. Check for solution docs: use Glob on .claude/solutions/**/*.md — prior knowledge?
Step 2: Classify Intent

Read references/tool-catalog.md for the full routing table.

Map the user's situation to one of these categories:

CategorySignalsPrimary Commands
Starting outNo plans, new to pluginphx-intro
Ideation"explore", "brainstorm", "not sure", "how to approach", "vague idea"phx-brainstorm
New feature"add", "build", "implement", multi-filephx-plan → phx-work
Quick changeSingle file, <50 lines, "fix typo"phx-quick
BugError, stack trace, "broken", "failing"phx-investigate
Review"check", "review", PR readyphx-review
Performance"slow", "N+1", "memory"phx-perf, ecto-n1-check, lv-assigns
Research"how to", "best practice", "evaluate lib"phx-research
Resume workExisting plan with unchecked tasksphx-work --continue

Returning after time off"what did I miss", "back from vacation", "catch up", "what changed while I was out"/catchup (companion plugin, separate install)
Show full SKILL.md (215 more words)Show less
Step 3: Respond or Clarify

If high confidence (clear match to one category): Present the recommendation with:

  • The command to run (with exact syntax)
  • One-line explanation of what it does
  • What artifacts it creates (if any)
  • Suggested next step after it completes

If medium confidence (2-3 possible matches): Use AskUserQuestion with the top options, each with a one-line explanation.

If low confidence (vague or no signal): Ask ONE focused clarifying question. Examples:

  • "Are you starting something new or continuing existing work?"
  • "Is this a bug fix or a new feature?"
  • "How many files do you expect to change?"

Then recommend based on the answer.

Step 4: Offer Follow-up

After recommending, always add:

  • "Run phx-help anytime to get routing advice"
  • If they seem new: "Try phx-intro for a full plugin walkthrough"

Iron Laws

  1. ONE recommendation — don't dump the full catalog, pick the best match
  2. MAX ONE clarifying question — don't interrogate, make your best guess
  3. Show exact syntax — phx-plan Add user notifications not just "use the plan command"
  4. Context over keywords — existing plans + git state matter more than word matching
  5. NEVER block — if user already knows what they want, DO NOT redirect

Integration

  • Complements intent-detection (auto-trigger) with explicit invocation
  • References same routing logic but adds interactive clarification
  • Can recommend phx-intro for onboarding
