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 | $0.10728 | $0.10728 |
| Opus 5.5 | $0.04291 | $0.04291 |
| Sonnet 5.5 | $0.02146 | $0.02146 |
| Haiku 4.5 | $0.01073 | $0.01073 |
Grade E, and why
progress-observability-plugin copilot-instructions.md scanned grade E with 3 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 15d 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.

Copilot instructions: Progress Observability
This file is generated from the plugin's skills. Do not edit it directly — edit the sources and run
python scripts/build_copilot.py. If anything here conflicts with what the user asks for, the user's request wins.
This project works with the Progress Observability Platform over the
progress-observability MCP server. Seven skills are available — pick the one
that matches the request (each also has a matching /prompt):
- instrument-agent — retrofit instrumentation onto an existing Python, TypeScript, or .NET agent, then hand off to health-check to confirm traces arrive. Start here: nothing else has anything to read until traces are flowing.
- scaffold-agent — create a new .NET agent project, already instrumented, from the starter template.
- health-check — verify the setup is wired up: connection, key scope, data flow, instrumentation depth. Run first when something looks wrong.
- trace-triage — root-cause a failed or slow run by walking its span tree.
- cost-report — spend by model/app/day, quota burn, spike explanation.
- coverage-gaps — find production behaviors with no eval; rank what to build.
- generate-eval — build a research-grounded LLM-as-a-Judge evaluator prompt.
Five of the seven only read from the MCP server and write nothing. The two that
write code: scaffold-agent creates a new project and makes no MCP calls;
instrument-agent edits an existing one and reads MCP only to verify.
MCP contract (applies to every workflow)
Endpoint: https://mcp.observability.progress.com/mcp — remote, read-only.
Auth: X-Api-Key header (the plugin's .mcp.json supplies it from
OBSERVABILITY_MCP_API_KEY). Access is scoped by key.
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.

progress-observability-plugin copilot-instructions.md is an instructions file published in the GitHub repository observability-oss/progress-observability-plugin (2 stars, last pushed 15d ago), licensed MIT. It adds 10,728 tokens to every session, about $0.0429 per session on Opus 5.5. A static security scan graded it E with 3 findings (hidden instructions, recursive force delete, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
