What is artemis copilot-instructions.md?

A repository-specific instruction guide for coding agents working on Artemis. It makes the root AGENTS.md file the main reference for workflow, context, checks, and handoff.

Following the repository’s agent workflow, selecting useful context, validating changes, and handing work to the next person or agent.

It gives an agent one agreed source of truth instead of leaving project rules scattered or unclear.

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	$0.00033	$0.00033
Opus 5.5	$0.00013	$0.00013
Sonnet 5.5	$0.00007	$0.00007
Haiku 4.5	$0.00003	$0.00003

Measured 2mo ago against content hash 90722b53c48b, method: parsed. Prices are Anthropic first-party input rates as of 2026-10-07, from the pricing page.

Security

Grade A, and why

artemis 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 2mo 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 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.
