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 | $0.00308 | $0.00308 |
| Opus 5.5 | $0.00123 | $0.00123 |
| Sonnet 5.5 | $0.00062 | $0.00062 |
| Haiku 4.5 | $0.00031 | $0.00031 |
Grade A, and why
reverse-engineering-assistant 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 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
- This is a Ghidra extensions for Ghidra 12.0 and later called "ReVa", the Reverse Engineering Assistant.
- The extension provides a Model Context Protocol (MCP) server for Ghidra. The server is implemented in Java and uses the MCP Java SDK.
- Remember that MCP is in development, so make sure to check the MCP documentation for the latest information.
Some good resources include:
-
If you want to find a Ghidra API, start from the FlatProgramAPI or the ProgramPlugin API in the Ghidra repo. Use the GitHub tools to search for Ghidra documentation.
-
We don't use a gradle wrapper, so just run
gradlein the root directory to build the project. We do have the Java tools installed in VSCode so you can just check for errors with VSCode instead. -
When writing tests, use the Ghidra test framework. The tests are in the
src/testdirectory. It is easy to run them withgradle test --infoand the integration tests withgradle integrationTest --info. -
You can use standard gradle test filtering to run specific tests with both of the test targets.
-
We target Ghidra 12.0 and later. Note we should use Java 21.
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.
