What is telegram-copilot-bridge copilot-instructions.md?

A project guide for a Python bridge that lets people control GitHub Copilot CLI, a command-line coding assistant, from a Telegram bot. It covers the project structure, configuration, sessions, and security rules.

Use it when changing the Telegram bot, Copilot CLI connection, configuration loading, session management, command routing, or the related tests.

It tells Copilot how the bridge is organized and how to handle users, credentials, permissions, updates, and multiple sessions safely.

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	$0.01413	$0.01413
Opus 5	$0.00707	$0.00707
Sonnet 5	$0.00283	$0.00283
Haiku 4.5	$0.00141	$0.00141

Security

Grade A, and why

telegram-copilot-bridge copilot-instructions.md scanned grade A with 1 finding 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 7d 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.

Runs shell commandslowCapability

Expected in a hook, worth knowing in a rule or an instructions file.

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.
