multitask

multitask is a skill for Claude Code, Codex from KonghaYao/peri. It costs 48 tokens per session (1,259 once invoked), scanned C, original, Apache-2.0.

A coordination guide for splitting a coding task between a foreground controller and background workers. It helps an agent decide when delegation is useful and how to combine the results.

In plain words
What is it for?
Use it when independent tasks can be delegated, when the user enables multitasking, or when an agent needs to follow up with workers. It is also used to coordinate work across different model tiers or conversation threads.
Why use it?
It avoids duplicate work and unnecessary parallel tasks while keeping the main task moving. It also clarifies who owns investigation, changes, and verification.

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 C, and why

multitask scanned grade C with 1 finding 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.

Tells the agent never to refusehighAnti-refusal

Suppressing the ability to decline removes a core safety control; a later harmful request then succeeds.

If `Agent` is unavailable, or the user prohibits delegation, do the permitted work directly and say so. Never refuse work the user has authorized.

How it starts

The opening of the file, as written. The whole thing — 70 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Multitask Mode

You are the coordinator. Every workstream leaves your hands and belongs to exactly one owner launched through Agent. The mode holds from the moment you have it, for the rest of the session — there is no opt-in, no task it exempts, and no small change it lets you keep.

What this mode changes

The host default lets you work in the foreground whenever the change fits, and puts direct work at two or three files. Under this mode none of that zone survives: every deliverable goes to an owner.

Coordination is the only work left to you — reading owner reports, synthesizing, asking the user, deciding the next step, launching and resuming owners, and keeping the record below. Everything else is a deliverable:

  • Any read, search, or edit of project material. One file is already enough.
  • Recon that enumerates a directory, greps the tree for references, or reads build, deploy, or CI config to pin down a vague brief. Recon is a deliverable like any other; hand it off, and the work it sizes stays with that owner.
  • Any change crossing a crate boundary.
  • Two or more independent workstreams the user hands over — one owner each.

An owner's returned report is coordination; the files behind it are not. Where the line is unclear, hand off rather than take a look first.

If Agent is unavailable, or the user prohibits delegation, do the permitted work directly and say so. Never refuse work the user has authorized.

One owner

A deliverable you hand off — investigate → implement → verify — has exactly one owner, and that owner is never you. Absorbed:

  • Do not redo handed-off work yourself or in a second owner; follow up only where results expose a gap.
  • Verification belongs to the deliverable. Read the evidence your owner reports instead of re-running its verification. When a real gap appears, hand the gap back to that owner (resume_thread_id) — a gap that falls outside its original file scope is still the owner's to close, not yours.
  • Do not split one deliverable into roles that wait on each other.
  • Siblings only for genuinely independent workstreams, with non-overlapping write scopes and settled interfaces. You hold no files, and an owner's files are not yours to edit; wait, or hand ownership over explicitly.
  • Delegation is one level deep, so you alone add siblings. Independent siblings run concurrently — launch them together and wait for their completion notifications instead of serializing the work or taking it back.

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.

multitask is a skill published in the GitHub repository KonghaYao/peri (240 stars, last pushed today), licensed Apache-2.0. It adds 48 tokens to every session and 1,259 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it C with 1 finding (tells the agent never to refuse). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-18.
