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 | $0.01026 | $0.01026 |
| Opus 5 | $0.00513 | $0.00513 |
| Sonnet 5 | $0.00205 | $0.00205 |
| Haiku 4.5 | $0.00103 | $0.00103 |
Grade A, and why
erp-report-engine 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 8d 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.
How it starts
The opening of the file, as written. The whole thing — 44 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Copilot instructions — erp-report-engine
A read-only, self-verifying data layer over the SQL database behind an ERP: a weekly HTML KPI report, a Power BI project, and a guarded MCP server for AI agents. Python 3.10–3.14, hatchling build. Runtime deps: pandas, sqlalchemy, sqlglot, jinja2, pyyaml (+ optional mcp extra). Dev: pytest, ruff, hypothesis.
Build, test, lint
pip install -e ".[dev,mcp]" # install with dev + MCP extras
python -m pytest tests/ -q # full suite (guard, calendar, MCP, end-to-end on the demo DB)
python -m ruff check erp_report_engine demo tests
erp-report-engine init-demo # build the bundled demo DB + config
erp-report-engine trust-benchmark # run the read-only guard against its attack corpus (no DB)
CLI verbs: init-demo, validate, run, export-powerbi, mcp, trust-benchmark, schema.
Architecture (one-way data flow)
config → profile → guard.py (4-layer read-only) + connect (audit) → extract → data-quality gate + COUNT(*) reconciliation → kpi (calendar-anchored) → insights (XmR + p-chart) → render / export_powerbi / mcp_server
- Pure core (
kpi.py,insights.py,spc.py,week_calendar.py): pandas/stdlib only, no I/O. Never import the I/O edge (connect,sqlalchemy,render) from here. - The guard (
guard.py): the read-only guard,re+sqlglotonly, so it runs standalone (the browser playground loads it verbatim).connect.pyre-exports it. - I/O edge:
connect.pyis the only path to the database. Route every query throughconnect.safe_read— do not open a second connection path. - Surfaces (
cli.py,mcp_server.py) are thin consumers of therunner.pyfacade (validate/build_report/guarded_query). - Contracts:
semantic.py(CANONICAL_SCHEMA— canonical entities + per-column meaning),attack_corpus.py(the shared guard benchmark),errors.py(exit-code taxonomy).
Invariants — do not weaken
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.

erp-report-engine copilot-instructions.md is an instructions file published in the GitHub repository gulmezeren2-byte/erp-report-engine (1 stars, last pushed 1mo ago), licensed MIT. It adds 1,026 tokens to every session, about $0.0051 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.
