Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00027 | $0.00982 |
| Opus 5 | $0.00014 | $0.00491 |
| Sonnet 5 | $0.00005 | $0.00196 |
| Haiku 4.5 | $0.00003 | $0.00098 |
Grade A, and why
parallel-task 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 4d 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.
How it starts
The opening of the file, as written. The whole thing — 159 lines — stays where its author put it; the contents beside it link to each section on GitHub.
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 task
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-task is a skill published in the GitHub repository jdrhyne/agent-skills (241 stars, last pushed 5d ago), licensed MIT. It adds 27 tokens to every session and 982 once invoked, about $0.0001 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 2026-08-30.
