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 | $0.00418 | $0.00418 |
| Opus 5.5 | $0.00167 | $0.00167 |
| Sonnet 5.5 | $0.00084 | $0.00084 |
| Haiku 4.5 | $0.00042 | $0.00042 |
Grade A, and why
MIF 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.
What it actually says
MIF Project - Copilot Instructions
About This Project
MIF (Modeled Information Format) is an open standard for portable AI memory representation with dual formats: Markdown and JSON-LD.
Ontology Management
This project includes an ontology system for organizing memories.
When working with ontology files (.ontology.yaml):
- Use the ontology manager agent:
.github/agents/ontology-manager.agent.md - Scripts:
.claude/skills/ontology-manager/scripts/ - Schema:
schema/ontology/ontology.schema.json
Quick Commands
# Validate an ontology
bash .claude/skills/ontology-manager/scripts/validate_ontology.sh <file.yaml>
# Scaffold a new ontology
bash .claude/skills/ontology-manager/scripts/scaffold_ontology.sh <id> <ver> > out.yaml
# Inspect ontology contents
bash .claude/skills/ontology-manager/scripts/inspect_ontology.sh <file.yaml>
# Convert formats
bash .claude/skills/ontology-manager/scripts/convert_format.sh yaml2json <in.yaml>
Key Conventions
- Ontology IDs: lowercase with hyphens (
my-domain) - Entity names: lowercase with hyphens (
support-ticket) - Base types:
semantic,episodic,procedural - Namespaces follow the cognitive triad:
_semantic/,_episodic/,_procedural/ - Version strings: semver (
0.1.0) - All ontologies should typically extend
mif-base

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.

MIF copilot-instructions.md is an instructions file published in the GitHub repository modeled-information-format/MIF (13 stars, last pushed yesterday), licensed MIT. It adds 418 tokens to every session, about $0.0017 per session on Opus 5.5. 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.
