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 | $0.00329 | $0.00329 |
| Opus 5.5 | $0.00132 | $0.00132 |
| Sonnet 5.5 | $0.00066 | $0.00066 |
| Haiku 4.5 | $0.00033 | $0.00033 |
Grade A, and why
neqsim 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 28d 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
NeqSim — Copilot Instructions
All agent rules are in AGENTS.md at the repository root. VS Code loads it automatically; if it is not already in your context, read it once. Detail is in docs/development/AGENT_REFERENCE.md (search it; never read it whole). Repeated below for tools that read only this file (e.g. code review):
- Java 8 only, tests included: no
var,List.of/Set.of/Map.of,String.repeat(useStringUtils.repeat),isBlank/strip/lines, text blocks, records, pattern-matchinginstanceof,Optional.isEmpty(). - Logging: Log4j2 logger with parameterized calls; never
System.out/err.println. - Formatting: run
mvnw spotless:applyafter editing any.javafile; CI runsspotless:check. - JavaDoc on every class and method (private too):
@param,@return,@throws; HTML5 tables need<caption>;@seeonly with Java references; no orphan</p>after lists. - Serializable classes: non-serializable fields must be
transient. - Verify constructor and method signatures before using an API; doc snippets need a passing test.
- After a flash, call
fluid.initProperties()before reading transport properties; always set a mixing rule.
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.
