| name | intent-detection |
| description | Route ambiguous or mixed Phoenix/LiveView/Ecto requests before choosing a workflow. Use when user is unsure where to start/how to approach work, asks for the right workflow, or combines intents such as fixing and refactoring. NOT for a clear task. |
Intent Detection — Workflow Routing
When user describes work WITHOUT specifying a /phx-* command, analyze their intent and suggest the appropriate workflow BEFORE starting work.
Hard guard — check FIRST: if the message starts with any slash command
(/phx-*, /ecto-*, /lv-*, or any other /command), this skill does not apply.
Follow the invoked command directly — no routing analysis, no suggestion, zero
output from this skill.
Routing Table
| Signal | Detected Intent | Suggest |
|---|
| "bug", "error", "crash", "failing", "broken", stack trace | Bug investigation | /phx-investigate |
| "brainstorm", "explore idea", "not sure what I need", "vague idea", "let's discuss", "how to approach" | Ideation/requirements | /phx-brainstorm |
| "add", "implement", "build", "create" + multi-step | New feature | /phx-plan |
| "review", "check", "audit" code | Code review | /phx-review |
| "fix" + small/specific scope | Quick fix | handle directly or /phx-quick |
| "refactor", "clean up", "improve" | Refactoring | /phx-plan (needs scope) |
| "research", "how to", "what's the best" | Research | /phx-research |
| "evaluate", "compare", "adopt", "library", "should we use" | Library evaluation | /phx-research --library |
| "test", "spec", "coverage" | Testing | handle directly or /phx-plan |
| Describes 1-2 file changes, < 50 lines | Small task | handle directly |
| "deploy", "release", "production" | Deployment | /phx-verify then deploy |
| "performance", "slow", "N+1", "memory" | Performance | /phx-perf |
| "PR review", "review comments", "address feedback", "respond to PR" | PR response | /phx-pr-review |
| "that worked", "fixed it", "problem solved" | Knowledge capture | /phx-compound |
| "enhance plan", "more detail", "deepen" | Plan enhancement | /phx-plan --existing |
| "triage", "which findings", "prioritize fixes" | Finding triage | /phx-triage |
Behavior
- Read user's first message
- Match against routing table (use keyword + context signals, not exact match)
- If match found with multi-step workflow: "This looks like [intent]. I'd suggest
[command] — want me to run it, or should I just dive in?"
- If trivial task (typo, single-line fix, config change): skip suggestion, just do it
- If user already specified a
/phx-* command: follow it, don't re-suggest
- NEVER block the user — suggestion only, not mandatory
Confidence Signals
High confidence (suggest immediately):
- Stack trace or error message pasted →
/phx-investigate
- "Add [feature] with [multiple components]" →
/phx-plan
- "Review my changes" or "check this PR" →
/phx-review
Medium confidence (suggest with caveat):
- "Fix [thing]" — could be quick or complex, suggest based on scope description
- "Update [thing]" — could be small edit or refactor
Low confidence (just do it):
- Single file mentioned, clear change
- "Change X to Y"
- Configuration or dependency updates
Complexity Signals
When a task matches a workflow command, check complexity before suggesting:
Trivial signals (suggest /phx-quick or handle directly):
- Single file mentioned explicitly
- "exclude X from Y", "add X to config", "rename", "change X to Y"
- Problem + solution both stated ("X is wrong, change to Y")
- One-line fix described
Complex signals (suggest /phx-plan or /phx-investigate):
- 3+ modules or files mentioned
- "intermittent", "race condition", "sometimes", "random"
- Stack trace with 5+ frames
- "across", "all", "every" (scope indicators)
Override rule: If user invokes /phx-full but task matches trivial signals:
"This looks like a quick fix. Want /phx-quick instead, or stick with the full cycle?"
Iron Laws
- NEVER block on suggestion — If user starts explaining, just do the work
- One suggestion max — Don't re-suggest if user ignores first suggestion
- Commands are shortcuts, not gates — All work can be done without commands
Routing Logic Example
if has_slash_command($ARGUMENTS) -> follow command directly
elif has_stack_trace(message) -> suggest /phx-investigate
elif matches("add|build|implement", message) and multi_step -> suggest /phx-plan
elif matches("fix", message) and small_scope -> handle directly or /phx-quick
elif matches("review|audit", message) -> suggest /phx-review
else -> handle directly (no suggestion)
Integration
This skill is consulted at session start. It works alongside:
- SessionStart hook (shows plugin loaded message)
- CLAUDE.md routing instructions (passive reference)
- Individual workflow skills (activated by commands)
