What is exe-parallel?

A command for creating several isolated workspaces, called worktrees, so multiple agents can implement the same feature separately. A worktree is an additional checkout of the same code repository.

Use it to run parallel versions of an engineering plan, test each version in isolation, and choose the best result.

It lets you compare independent implementations without mixing their file changes together.

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.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00000	$0.00322
Opus 5	$0.00000	$0.00161
Sonnet 5	$0.00000	$0.00064
Haiku 4.5	$0.00000	$0.00032

Security

Grade A, and why

exe-parallel 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 6d 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.

What it actually says

Parallel Task Version Execution

Variables

PLAN_TO_EXECUTE: $ARGUMENTS NUMBER_OF_PARALLEL_WORKTREES: $ARGUMENTS

Run these commands top to bottom

RUN eza server --tree --git-ignore RUN eza client --tree --git-ignore RUN eza trees --tree --level 3 READ: PLAN_TO_EXECUTE

Instructions

We're going to create NUMBER_OF_PARALLEL_WORKTREES new subagents that use the Task tool to create N versions of the same feature in parallel.

This enables use to concurrently build the same feature in parallel so we can test and validate each subagent's changes in isolation then pick the best changes.

The first agent will run in trees/<predefined_feature_name>-1/ The second agent will run in trees/<predefined_feature_name>-2/ ... The last agent will run in trees/<predefined_feature_name>-<NUMBER_OF_PARALLEL_WORKTREES>/

The code in trees/<predefined_feature_name>-/ will be identical to the code in the current branch. It will be setup and ready for you to build the feature end to end.

Each agent will independently implement the engineering plan detailed in PLAN_TO_EXECUTE in their respective workspace.

When the subagent completes it's work, have the subagent to report their final changes made in a comprehensive PCC_RESULTS.md file at the root of their respective workspace.

Make sure agents don't run start.sh or any other script that would start the server or client - focus on the code changes only.

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.
