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 | $0.00438 | $0.00438 |
| Opus 5 | $0.00219 | $0.00219 |
| Sonnet 5 | $0.00088 | $0.00088 |
| Haiku 4.5 | $0.00044 | $0.00044 |
Grade A, and why
alpacon-mcp 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 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.
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
Writing style
General rules
- Sentence case: Use sentence case for all headings and titles (capitalize only the first word and proper nouns)
- Correct: "## Available MCP tools", "### Key architecture principles"
- Incorrect: "## Available MCP Tools", "### Key Architecture Principles"
- Em-dash: No spaces around em-dashes
- Correct: "remote/streamable-http mode—not stdio"
- Incorrect: "remote/streamable-http mode — not stdio"
- Itemized descriptions: Use a colon, not a dash, to separate an item from its description in bullet lists
- Correct:
- `list_servers`: List all servers in workspace - Incorrect:
- `list_servers` - List all servers in workspace
- Correct:
Technology names
- Websh: Always use "Websh" (not "WebSH") for the web shell. This MCP server exposes no Websh tools, but the term still appears in settings and audit surfaces
- Correct:
websh_session_timeout, "Websh session analysis" - Incorrect:
webSH_session_timeout, "WebSH session analysis"
- Correct:
- WebFTP: Use "WebFTP" for file transfer functionality
- MCP: Use "MCP" for Model Context Protocol
Code conventions
- Imports: Keep imports at the top of the file. A function/method-local import needs a real reason—breaking a circular import, gating an optional/heavy dependency, or deferring for a documented ordering hazard—stated in a one-line comment
- Correct:
# Local: real circular import—tools/resources.py imports server at its own top level.followed by the import - Incorrect: an import placed inside a function body with no comment explaining why
- Correct:
Language guidelines
- All code comments, documentation, commit messages, PR titles/descriptions, docstrings, and variable/function/class names: English only
- User-facing CLI/console output messages: English, matching the rest of the project
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.

alpacon-mcp copilot-instructions.md is an instructions file published in the GitHub repository alpacax/alpacon-mcp (1 stars, last pushed today), licensed MIT. It adds 438 tokens to every session, about $0.0022 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
