parallel

A command that plans how independent coding agents can work on separate tasks at the same time. A worktree is an isolated copy of a Git project for one branch.

In plain words
What is it for?
Use it to find parallel task groups, map file conflicts, assign branches and worktrees, set merge order, and require integration checks.
Why use it?
It helps prevent agents from editing the same files, defines which tasks can run together, and sets a safe order for merging their work.

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.

Security

Grade A, and why

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 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.

What it actually says

Invoke the forge-skills:parallel-execution-strategy skill.

Read .forge/tasks.yaml. Identify dependency-free groups — both depends_on AND files lists must not intersect. Build a file-conflict matrix per group. Any row with two ✏️ marks is a conflict — split, sequence, or designate a primary. Assign one branch per task (task/T-XXX-description), all based off main. Define PR sequencing and merge order before dispatch. Lowest-blast-radius first; tasks that mutate shared types/contracts land first so others rebase on them. Each agent runs in its own git worktree — never share. Define integration-test gate between every merge and between groups.

After writing: "Parallel plan written to .forge/parallel-plan.md. Dispatch only after the plan is signed off."

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.

parallel is a command published in the GitHub repository aneja5/forge-skills (3 stars, last pushed 3mo ago), licensed MIT. It adds 19 tokens to every session and 188 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 2026-08-31.
