agent-spawn

agent-spawn is a skill for Claude Code, Codex from mattmre/EVOKORE-MCP-PUBLIC. It costs 28 tokens per session (415 once invoked), scanned A, original, MIT.

A tool for assigning a focused coding task to a specialist sub-agent, such as a researcher, implementer, tester, reviewer, architect, or debugger.

In plain words
What is it for?
Use it to delegate codebase searches, feature changes, test writing, reviews, security checks, design decisions, or bug investigations.
Why use it?
It keeps detailed investigation or implementation work separate from the main session and matches tasks to a suitable specialist role.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

agent-spawn scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 5d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

/agent-spawn — Spawn Specialist Sub-Agent

Delegates a specific task to a specialist sub-agent, keeping the main session context clean.

Usage

/agent-spawn "researcher" "Find all usages of TrustLedger in src/"
/agent-spawn "implementer" "Implement the score decay function in src/TrustLedger.ts"
/agent-spawn "tester" "Write vitest tests for pattern-extractor.js"

Available Archetypes

Archetype Domain Best for
researcher research Codebase analysis, dependency tracing
implementer execution Feature implementation, bug fixes
tester quality Test writing, coverage analysis
reviewer quality Code review, security audit
architect orchestration Design decisions, API design
debugger execution Root cause analysis, bug investigation

What it does

  1. Creates an Agent tool call with the specified subagent_type
  2. Passes the task description and relevant context
  3. The sub-agent runs in isolation and returns a result
  4. Result is summarized in the main session context

Best practices

  • Use researcher before implementer (plan before code)
  • Keep sub-agent prompts self-contained (include file paths, context)
  • Use isolation: worktree for implementers that write code
  • Prefer sequential spawning to avoid worktree race conditions

Integration

  • Works with AGT-019 (Claims Coordinator) for resource claim management
  • Sub-agent results are captured in session-replay log
  • SessionAnalyticsManager tracks subagent counts per session
Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

Use this BEFORE any creative or feature work: building a new feature, adding functionality, changing behavior, or making a nontrivial design decision. Turns the user's request into a validated design — recorded as a spec-graph task-spec — before any implementation. Do not skip this because a change looks small.
