Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00209 | $0.00209 |
| Opus 5.5 | $0.00084 | $0.00084 |
| Sonnet 5.5 | $0.00042 | $0.00042 |
| Haiku 4.5 | $0.00021 | $0.00021 |
Grade A, and why
backwards-compatibility 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 1mo 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
Cursor Development Rules for Compozy
Backwards Compatibility
<compatibility_policy type="development_phase"> NO BACKWARDS COMPATIBILITY REQUIRED - Compozy is currently in active development/alpha phase. </compatibility_policy>
<development_guidelines> When developing, refactoring, or fixing features:
- Feel free to make breaking changes to APIs, configs, and data structures
- Don't worry about maintaining old interfaces or migration paths
- Focus on building the best architecture and design patterns
- Prioritize code quality and maintainability over compatibility </development_guidelines>
<scope_of_changes> This policy applies to:
- Database schema changes
- API endpoint modifications
- Configuration file structure
- Internal interfaces and contracts
- Tool and workflow definitions </scope_of_changes>
<future_policy> Once we reach beta/stable release, we'll implement proper versioning and compatibility policies. </future_policy>
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.

backwards-compatibility is a cursor rule published in the GitHub repository compozy/gograph (9 stars, last pushed 1y ago), licensed MIT. It adds 209 tokens to every session, about $0.0008 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.
