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

agent-harness-plugins workflow-git.instructions.md 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 8d 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

Git Commands in Workflows

For repo-wide conventions, see copilot-instructions.md and AGENTS.md at the repository root.

  • git worktree add --orphan -b <branch> <path> is correct. Since Git 2.42, --orphan is a flag that makes the new branch named by -b or -B an unborn branch; it takes no argument of its own. git worktree add -h prints the synopsis [--orphan] [(-b | -B) <new-branch>] <path> [<commit-ish>]. Do not suggest dropping -b or moving the branch name after --orphan.
  • A push from the main checkout can publish a branch committed in a linked worktree. Worktrees share the repository's refs, so git push origin refs/heads/<branch>:refs/heads/<branch> from the checkout that holds the persisted credentials is deliberate, not a mismatch.
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.
