parallel-work

parallel-work is a skill for Claude Code, Codex from gabrieldabbah/genesis. It costs 75 tokens per session (1,205 once invoked), scanned A, original, MIT.

Rules for working in a repository while another coding-agent session is editing it. They keep each session’s changes separate and avoid actions that could disrupt the other work.

In plain words
What is it for?
Use it to make scoped edits without Git writes, process termination, cleanup, or broad verification that could affect another session.
Why use it?
Shared files, processes, tests, and Git state can interfere with one another when multiple sessions work at once.

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-work 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 — 82 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Parallel session mode

Another Claude session is working in this repository right now. The working tree, the running processes, the git index, and whatever the tests touch are all shared. Assume every one of them has an owner other than you.

Rules

  1. No git writes. Do not commit, push, stage, stash, checkout, reset, restore, merge, rebase, or switch branches. Finish the work, leave it uncommitted, and say so. The owner commits.
  2. Diffs you did not make are not yours. git status will show another session's in-flight edits. Never revert, clean, or "tidy" them. If a file you are editing changes under you, re-read it and merge your change on top — do not overwrite.
  3. Stay inside the requested scope. Touch only the files the request names or strictly requires. No drive-by refactors and no reformatting. A problem in a file you are not already editing is named in the report and never fixed here — it probably belongs to another session's in-flight work, and an unrelated file you edit is a file you are colliding with someone on. A defect in a file you are already changing stays yours to fix, in this mode as in every other.
  4. Do not kill processes. No pkill, killall, port sweeps, or container teardowns — the dev server, test run, or database you would kill probably belongs to the other session. Kill only a PID you spawned this turn and captured yourself. Leftovers you did not spawn get reported, not killed.

Verifying without corrupting anyone

A test run is not a read. Most suites write: they insert fixtures, truncate or reset a database, bind a fixed port, populate a cache, or write to a shared build directory. Run one while another session is mid-run and you corrupt both — and that is worse than a wasted run, because the wreckage looks like real findings. Rows vanish mid-assertion, a port refuses to bind, a snapshot mismatches, a count comes back one too high. Whoever reads that output then debugs a bug that does not exist. Both sessions lose, and the false result is the expensive part.

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-work is a skill published in the GitHub repository gabrieldabbah/genesis (4 stars, last pushed 1mo ago), licensed MIT. It adds 75 tokens to every session and 1,205 once invoked, about $0.0004 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.
