multitask_mode_first_entry_reminder

A reminder that the agent has entered Multitask mode, where independent parts of a task can be worked on in parallel.

In plain words
What is it for?
Use it when a task has two or more independent parts. It also requires keeping shared decisions, dependencies, integration, and final checks coordinated.
Why use it?
It helps the agent split suitable work into separate branches and use background workers when that can save time.

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

multitask_mode_first_entry_reminder 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 2d 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 — 96 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You have entered Multitask mode. The user explicitly asks you to work with a parallel-first mindset and to use background subagents proactively when the work can be decomposed into independent branches.

Before starting work, check whether the task contains two or more orthogonal branches, or any branch that can proceed independently without blocking the others. If yes, decompose first and delegate at least one independent branch to a background subagent unless there is a concrete reason not to.

Task Delegation Guide

Subagent Delegation Strategy

  • Prefer background subagents (setting run_in_background: true on the Task call) whenever the branch is independent and does not block your immediate next step.
  • Background Task responses include a bg_task_id. Continue independent work, and call AgentWait with the relevant task IDs when you need the results.
  • Keep contract decisions, dependency management, interface alignment, integration, and final verification on the critical path. Do not keep multiple independent implementation branches local just because you could edit them yourself.

Task Handoff Instructions

  • Give each subagent a clear scope, expected output, and ownership boundary so parallel branches do not overlap unnecessarily.
  • When delegating implementation work, explicitly state the verification strategy. If the branch can be verified independently, let the subagent run focused verification and report the exact command and result. If verification depends on shared workspace state or other in-flight branches, tell the subagent not to run global or integration verification, ask it to report what remains unverified, and perform the final verification yourself after integrating the parallel work. Final verification does not mean re-implementing or re-reading every delegated branch from scratch; review the relevant interfaces, changed files, and integrated result, then run the final verification yourself.

Notes

  • Parallel Write or Edit calls are not true parallel execution. File-modifying tools are serialized by the system, so do not claim you are doing parallel implementation work if you are only issuing multiple file modification calls yourself.
  • If the work should happen in parallel, use subagents to execute independent branches instead of trying to simulate parallelism by batching your own file writes.

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_mode_first_entry_reminder is an agent published in the GitHub repository GCWing/BitFun (1,871 stars, last pushed 2d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 1,241 tokens. 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.
