Use it when Copilot starts or finishes a repository task, creates a worker branch, reads project handoff documents, or prepares changes for a pull request.

It gives Copilot a shared process for avoiding conflicting changes, protecting secrets, and recording work for the next developer.

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	$0.00373	$0.00373
Opus 5	$0.00187	$0.00187
Sonnet 5	$0.00075	$0.00075
Haiku 4.5	$0.00037	$0.00037

Security

Grade A, and why

multi-agent-repo-handoff-skill copilot-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 9d 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

GitHub Copilot Instructions

This repository may be worked on by multiple coding agents. GitHub and repository documents are the source of truth; chat history and local uncommitted changes are not.

First Read

Before changing code, read:

AGENTS.md
WORKLOG.md
TODO.md
docs/WORKERS.md
docs/OPERATING_MODEL.md
docs/HANDOFF.md
docs/WORKER_ONBOARDING.md
Project-specific architecture, data, and test documentation.

Branch Rules

Do not work directly on main.
Use a dedicated <worker-name>-wip branch.
Do not let two workers share a WIP branch concurrently.
Completed work should go to main through a PR.

Start

git status --short --branch
scripts/start_worker.sh --branch <worker-name>-wip

End

scripts/end_session.sh --commit -m "Describe completed work" --push

If there are no changes, run:

scripts/end_session.sh

Safety

Do not commit .env, API keys, account numbers, tokens, private certificates, raw data, generated reports, or large generated artifacts.
Do not run network/data download/live/production commands unless secrets are configured and the user explicitly expects it.
scripts/start_worker.sh fetches remotes and fast-forwards the worker branch by default. Update WORKLOG.md, TODO.md, and docs/WORKERS.md after meaningful work.
If validation fails, record the exact command and failure before handoff.

Use these rules when GitHub Copilot or Copilot CLI works in this repository.

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.
