parallel-agents

parallel-agents is a skill for Claude Code from hnikoloski/imlazy. It costs 43 tokens per session (753 once invoked), scanned A, original, MIT.

A workflow for sending independent coding problems to multiple subagents at the same time. A subagent is a separate AI worker focused on one task.

In plain words
What is it for?
Investigating separate test failures, debugging independent subsystems, and reviewing and combining parallel fixes.
Why use it?
It reduces waiting when unrelated failures or investigations can be handled separately, while avoiding conflicts over shared files.

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

parallel-agents 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 10d 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.

When to use

Use when you have 2+ independent problems that can each be solved without knowing the others' results.

Use when:

  • 3+ test files failing with different root causes
  • Multiple subsystems broken independently
  • Each problem can be understood without context from the others
  • No shared state between investigations (no editing the same files)

Do not use when:

  • Failures are related (fix one might fix others — investigate together first)
  • Need to understand full system state before starting
  • Agents would edit the same files (conflicts)

The pattern

  1. Identify independent domains. Group failures by what's broken. Each domain is its own agent scope.

  2. Create focused agent tasks. Each agent gets: specific scope (one file or subsystem), clear goal (make these tests pass), constraints (don't change other code), expected output (summary of root cause and changes).

  3. Dispatch in parallel. All agents run concurrently.

  4. Review and integrate. When agents return: read each summary, verify fixes don't conflict, run full test suite.

Good agent prompt structure

Fix the 3 failing tests in src/agents/agent-tool-abort.test.ts:

1. "should abort tool with partial output capture" — expects 'interrupted at' in message
2. "should handle mixed completed and aborted tools" — fast tool aborted instead of completed
3. "should properly track pendingToolCount" — expects 3 results but gets 0

These are likely timing/race condition issues. Your task:
1. Read the test file and understand what each test verifies
2. Identify root cause — timing issues or actual bugs?
3. Fix — replace arbitrary timeouts with event-based waiting if needed

Do NOT just increase timeouts — find the real issue.

Return: summary of root cause and what you fixed.

Common mistakes:

  • Too broad: "Fix all the tests" — agent gets lost → Too specific: "Fix agent-tool-abort.test.ts"
  • No context: "Fix the race condition" → Paste the error messages and test names
  • No constraints → "Do NOT change production code" / "Fix tests only"
  • Vague output: "Fix it" → "Return summary of root cause and 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.

parallel-agents is a skill published in the GitHub repository hnikoloski/imlazy (2 stars, last pushed 1mo ago), licensed MIT. It adds 43 tokens to every session and 753 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
