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 | $0.01056 | $0.01056 |
| Opus 5.5 | $0.00422 | $0.00422 |
| Sonnet 5.5 | $0.00211 | $0.00211 |
| Haiku 4.5 | $0.00106 | $0.00106 |
Grade A, and why
d365fo-client 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.

Cross-platform wrappers exist and mirror the same workflows:
- Unix:
make dev,make quality-check,make test-unit,make build - PowerShell:
.\make.ps1 dev,.\make.ps1 quality-check,.\make.ps1 test-unit,.\make.ps1 build
CI installs with uv sync --all-extras, runs uv run pytest tests/ --cov=src/ --cov-report=xml, and builds with uv build.
High-level architecture
This repo has three connected surfaces that share the same core client:
- Python client:
src/d365fo_client/client.pydefinesFOClient, which composes auth, HTTP session management, CRUD helpers, metadata API helpers, and label operations. Metadata is initialized lazily and uses the V2 cache/search/sync stack undersrc/d365fo_client/metadata_v2/. - CLI:
src/d365fo_client/main.pybuilds the argparse tree, andsrc/d365fo_client/cli.pyroutes commands throughCLIManager, which resolves config and then runs the sameFOClient. - MCP server:
src/d365fo_client/mcp/fastmcp_main.pyis the entry point,fastmcp_server.pyassembles the FastMCP server, and tool implementations live in mixins undersrc/d365fo_client/mcp/mixins/.D365FOClientManagerpoolsFOClientinstances per profile for MCP use.
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.
