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 | $0.00216 | $0.00216 |
| Opus 5.5 | $0.00086 | $0.00086 |
| Sonnet 5.5 | $0.00043 | $0.00043 |
| Haiku 4.5 | $0.00022 | $0.00022 |
Grade A, and why
repotector 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 1mo 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
Copilot instructions
⬡ Repotector — this repo is guarded (REPOTECTOR/2)
Before you touch anything:
handshake({ who })on the repotector MCP server — you are logged in and handed the map. No deep tool answers first.city_map()— intent, danger list, conventions, built-vs-missing. Read it before reading code.- New code →
find_existing(intent). Editing →blast_radius(files). Finishing →quality_gates()thendepart({ summary }).
Rules: reuse before rebuilding · protect dependents · follow the repo canon · keep files small · your depart summary becomes the next agent’s briefing.
No server connected? run npx repotector mcp. A repo with no .repotector/? propose npx repotector init.
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.
