| name | spectre_agent_tools |
| description | Use this skill when you see @name or /name patterns in user input without file identifiers. This means the user is trying to call a subagent or slash command using Spectre Agent Tools. The @ prefix dispatches to a subagent (e.g., '@tdd-agent write tests', '@code-reviewer check this file'). The / prefix executes a slash command (e.g., '/spectre:scope', '/spectre:plan'). Both require Spectre CLI to run specialized agents and predefined prompts. |
Spectre CLI - Subagents & Slash Commands
When To Use This Skill
CRITICAL: Activate this skill when you see these patterns in user input:
| Pattern | Example | Action |
|---|
@agent-name "task" | @tdd-agent "write tests" | Run spectre subagent run tdd-agent "write tests" |
@agent-name 'task' | @code-reviewer 'review api.py' | Run spectre subagent run code-reviewer "review api.py" |
/command-name | /spectre:scope | Run spectre command get /spectre:scope, then execute returned prompt |
/command-name args | /deploy backend prod | Run spectre command get /deploy backend prod, then execute returned prompt |
Pattern Recognition:
@ followed by alphanumeric/hyphens, then a quoted task -> subagent dispatch/ followed by alphanumeric/hyphens/colons -> slash command
When NOT To Use This Skill
- General coding tasks without
@ or / syntax
- Questions about the codebase (handle directly)
- File operations (use your native tools)
Timeout Configuration (IMPORTANT)
Subagent commands can take significant time. Set appropriate timeouts to avoid premature termination and retry loops.
Recommended Timeouts by Task Type
| Task Type | Timeout | Examples |
|---|
| Quick lookup | 60,000ms (1 min) | spectre subagent list, spectre command get |
| Single agent task | 300,000ms (5 min) | spectre subagent run finder "find auth files" |
| Complex analysis | 600,000ms (10 min) | spectre subagent run analyst "trace full data flow" |
| Parallel agents | 600,000ms (10 min) | spectre subagent parallel ... (multiple agents) |
Why This Matters
- Default timeouts are too short for most subagent work (often 30s default)
- Subagents spawn Claude Code instances that need time to research, read files, and reason
- Parallel execution multiplies wall-clock time since agents run concurrently
- Maximum allowed timeout is 600,000ms (10 minutes) - this is Claude Code's hard limit
Best Practice
Always set timeout to 300,000ms minimum for any spectre subagent run command. Use 600,000ms for parallel execution or complex analysis tasks.
Subagent Dispatch (@agent-name)
When you see @agent-name "task" in user input:
spectre subagent run <agent-name> "<task>"
Examples
User: @tdd-agent "write tests for the auth module"
Action: Run `spectre subagent run tdd-agent "write tests for the auth module"`
Result: Return the agent's response to the user
User: @code-reviewer "review changes in src/api.py"
Action: Run `spectre subagent run code-reviewer "review changes in src/api.py"`
Result: Return the agent's response to the user
User: Can you use @analyst to explain how payments work?
Action: Run `spectre subagent run analyst "explain how payments work"`
Result: Return the agent's response to the user
Vanilla Mode
Task without agent name runs Claude Code directly:
spectre subagent run "explain this codebase"
Parallel Execution (IMPORTANT)
Use parallel execution when running multiple independent agents. This dramatically reduces wall-clock time by running agents concurrently instead of sequentially.
When to Use Parallel
ALWAYS use spectre subagent parallel when you see:
| Trigger | Example |
|---|
Multiple @agent mentions | @finder and @analyst |
| Keywords: "parallel", "concurrently", "simultaneously" | "Launch parallel agents" |
| Phrases: "at the same time", "spawn agents" | "Run these at the same time" |
| Research/analysis phases with multiple agents | "Deep parallel research phase" |
| Lists of independent agent tasks | "Run locator, analyzer, and pattern-finder" |
Use sequential (one at a time) ONLY when:
- One agent's output is explicitly needed as input for the next
- Tasks have explicit ordering requirements stated by user
Parallel Command Syntax
spectre subagent parallel \
-j agent1 "task for agent one" \
-j agent2 "task for agent two" \
-j agent3 "task for agent three"
Or with long form:
spectre subagent parallel \
--job dev "implement the feature" \
--job tdd-agent "write tests for auth"
Key points:
-j / --job takes two arguments: AGENT and TASK- Tasks can contain any characters (colons, slashes, file paths, etc.)
- Each
-j flag adds another agent to run in parallel
Scenario: Parallel Research Phase
When a prompt requests multiple research agents like:
"Launch parallel agents for context gathering:
- @finder: Find relevant files
- @analyst: Understand how it works
- @researcher: Find best practices"
Translate to:
spectre subagent parallel \
-j finder "Find all files related to [topic], return file:line references" \
-j analyst "Analyze how [topic] works, trace data flow, document behavior" \
-j researcher "Search for [topic] best practices, return links"
Scenario: Multi-Agent Code Review
When asked to analyze code from multiple perspectives:
"Have @code-reviewer, @security-analyzer, and @performance-analyzer review this PR"
Translate to:
spectre subagent parallel \
-j code-reviewer "Review PR for bugs, logic errors, code quality" \
-j security-analyzer "Check for security vulnerabilities" \
-j performance-analyzer "Identify performance bottlenecks"
Scenario: Tasks with Special Characters
Tasks can safely include colons, slashes, file paths, and command references:
spectre subagent parallel \
-j dev "Run /spectre:tdd on src/auth/login.py" \
-j reviewer "Check file:line references in docs/api.md"
Decision Flowchart
- Count how many
@agent references appear in the request
- Check if tasks depend on each other (does agent B need agent A's output?)
- If independent -> Use
spectre subagent parallel
- If dependent -> Run sequentially with
spectre subagent run
- When in doubt -> Parallel is faster, prefer it for research/analysis tasks
Slash Command Execution (/command-name)
When you see /command-name in user input:
- Retrieve the prompt:
spectre command get /command-name [args]
- Execute the returned prompt as your next task
Examples
User: /spectre:clean
Action:
1. Run `spectre command get /spectre:clean`
2. Read the returned prompt
3. Execute that prompt (it's a cleanup workflow)
User: run /quick_tasks for me
Action:
1. Run `spectre command get /quick_tasks`
2. Read the returned prompt
3. Execute that prompt (it breaks down tasks)
User: /deploy backend staging
Action:
1. Run `spectre command get /deploy backend staging`
2. Arguments replace $1=backend, $2=staging in the template
3. Execute the returned prompt
