What it costs to keep this loaded
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 | $0.00058 | $0.00820 |
| Opus 5 | $0.00029 | $0.00410 |
| Sonnet 5 | $0.00012 | $0.00164 |
| Haiku 4.5 | $0.00006 | $0.00082 |
Grade A, and why
ghidra-headless 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 11d 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 — 68 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Ghidra Headless Analyzer
Build smallest safe ghidra-analyzeHeadless command for requested operation.
Workflow
- Confirm binary with
command -v ghidra-analyzeHeadless. - Choose exactly one mode:
-import <path>for new binaries;-process [pattern]for project programs. Omit both only for program-independent scripts. - Choose local
<project-dir> <project-name>[/folder]or existingghidra://...repository. - For raw firmware, select repository definitions explicitly:
- C167CR:
-loader BinaryLoader -processor C166:LE:16:default -cspec tasking - C167CS:
-loader BinaryLoader -processor C166:CS:LE:16:default -cspec tasking - Add
-loader-baseAddr <hex-address>when known.
- C167CR:
- Add only requested scripts, recursion, timeout, logs, read-only behavior, overwrite, or CPU limit.
- Quote paths containing spaces. Single-quote
-processwildcards so shell does not expand them. - Show complete command before execution and state what it may change.
- Check exit status and logs. Report processed files, warnings, timeouts, and saved/discarded changes.
Safety
- Prefer
-readOnlywhen inspecting existing projects. - Never add
-overwrite,-deleteProject,-commit,-okToDelete, or deletion disposition implicitly. - Before overwrite, identify files at risk. Before commit, confirm repository and comment.
- Before
-okToDelete, warn that process-mode deletion is permanent and can remove every version. - Never put passwords or private-key passphrases in command arguments.

What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

ghidra-headless is a skill published in the GitHub repository keyhana/c166-ghidra-module (55 stars, last pushed 17d ago), licensed MIT. It adds 58 tokens to every session and 820 once invoked, about $0.0003 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 2026-08-30.
