What it does
Parallel Task is an agent skill from jdrhyne/agent-skills. Coordinate plan files by launching multiple parallel subagents for unblocked tasks. Triggers on explicit "/parallel-task" commands.
Its SKILL.md is about 1k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Agent Workflows, covering Subagents. The repository describes itself as: A collection of AI agent skills for Clawdbot, Claude Code, Codex. The licence is MIT.
When your agent uses it
- Explicit /parallel-task commands
- Tasks that involve Subagents
Example prompts
- “/parallel-task”
- “/parallel-task”
Workflow steps
5 steps, taken from the step headings in SKILL.md.
What it can do on your machine
Read from SKILL.md and the folder at commit 439cd3a. 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 (its code samples are markdown).
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
Parallel Task loads about 1k tokens when it runs. Until then it costs about 36 tokens; SKILL.md has 344 words of instructions outside code blocks.
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.
SKILL.md

Parallel Task Runner
Use Orchestration Mode. Parse plan files and delegate tasks to parallel subagents.
Safety Boundaries
- Do not launch subagents for tasks that share write scope until the dependency is resolved.
- Do not continue past blockers silently; surface the blocked task and stop that branch of work.
- Do not mark tasks complete until validation from the plan has actually been checked.
- Do not run this skill unless the user explicitly invoked
/parallel-taskor clearly asked for parallel agent work.
Process
Step 1: Parse Request
Extract from user request:
- Plan file: The markdown plan to read
- Sprint/Phase (optional): Which section to run
If sprint not provided, ask user which to run.
Step 2: Read & Parse Plan
- Find sprint/phase section (e.g.,
## Sprint 1:) - Extract task subsections (e.g.,
### Task 1.1:) - For each task, extract:
- Task ID and name
- Full content (description, location, acceptance criteria, validation)
- Build task list
Step 3: Launch Subagents
For each task, launch subagent with:
- description: "Implement task [ID]: [name]"
- prompt: Use template below
If there are multiple unblocked tasks, launch multiple subagents in parallel.
Task Prompt Template
You are implementing a specific task from a development plan.
## Context
- Plan: [filename] - [sprint/phase]
- Goals: [relevant overview from plan]
- Dependencies: [prerequisites for this task]
- Related tasks: [tasks in same sprint]
- Constraints: [risks from plan]
## Your Task
**Task [ID]: [Name]**
Location: [File paths]
Description: [Full description]
Acceptance Criteria:
[List from plan]
Validation:
[Tests or verification from plan]
## Instructions
1. Examine and explore the plan, all relevant files & dependencies. Ensure ambiguities are cleared up.
2. Implement changes for all acceptance criteria
3. Keep work **atomic and committable**
4. For each file: read first, edit carefully, preserve formatting
5. Run validation if feasible
6. Return summary of:
- Files modified/created
- Changes made
- How criteria are satisfied
- Validation performed or deferred
## Important
- Be careful with paths
- Stop and describe blockers if encountered
- Focus on this specific taskStep 4: Monitor & Log
After subagents complete:
- Collect results
- ALWAYS mark completed tasks and update with:
- Concise work log
- Files modified/created
- Errors or gotchas encountered
Step 5: Repeat
Now, pause and read the whole plan again to see what new tasks are unblocked.
Start back at step 3. Continue launching agents on unblocked tasks in parallel.
Repeat this loop until the plan is done.
Do not stop until the plan is fully completed or you encounter a blocker.
Step 6: Validate
After completing all tasks, validate the plan's success by checking the final state against the original plan. Perform available tests and ensure success. If there are any issues, address them before marking the plan as complete.
After validation, provide a summary of:
- Files modified/created
- Changes made
- How criteria are satisfied
- Validation performed or deferred
Error Handling
- Sprint not found: List available sprints/phases
- Parse failure: Show what was tried, ask for clarification
