register-workstream

A command that registers a workstream, meaning a separate, named lane of work within a project. It can create a Git worktree, branch, or tracking record based on the project's setup.

In plain words
What is it for?
Use it to start or refresh a workstream, base it on another workstream, create a separate working directory, choose a target for pull requests, or record lineage only.
Why use it?
It provides a consistent place to do related work without guessing which project or base branch to use. Tracking-only mode records how workstreams relate without changing Git files.

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

register-workstream 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

Run the register-workstream action of the project-with-reflect skill with arguments: $ARGUMENTS

Resolve the project from the current directory first. Match $PWD against registry.json projects' repo / dir (the project whose repo contains $PWD). If none matches, ask which project — don't guess. (This is the same cwd→registry match the auto-log hook uses.)

Then parse the args — natural language is fine, you translate it to flags: "v081 based on v080, just track" → v081 --base v080 --track-only; "v090 tracking v081" → v090 --base v081 --track-only. Run:

register-workstream.sh <project_dir> <workstream> [--base <b>] [--pr-into <p>] [--track-only] [--path <dir>]
  • --track-only (a.k.a. "just track" / "tracking X") → records lineage only, no git (a shared version / integration branch you rebase onto and PR into, never commit to directly).
  • Otherwise the workstream is realized per the project's workstream_mode: worktreegit worktree add at <repo>/.claude/worktrees/<workstream> by default (auto-created, forked from origin/<base>, kept out of git status via a local .git/info/exclude entry — no prompt; pass --path <dir> to override). in-repogit checkout -b (HEAD switches — ready to work). logical → no git.
  • Re-registering an existing workstream updates its base/pr_into only — cycle / log / git untouched.

Generates the /<project>-<workstream> alias (whose bare form = checkin to that workstream). Follow the skill's steps; honor the behavioral contract.

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.
