What is headless-ghidra?

The entry point for a YAML-first reverse-engineering workflow using Headless Ghidra, the command-line form of Ghidra for analyzing compiled programs. It coordinates the workflow’s phases, checks progress, and pauses for review when needed.

It is for analyzing, decompiling, sorting, resuming, and iterating on compiled binary targets through the Headless Ghidra process.

It gives binary analysis a recorded sequence and shared state, making it possible to resume or iterate without losing the workflow’s progress.

Token cost

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	$0.00087	$0.01638
Opus 5	$0.00044	$0.00819
Sonnet 5	$0.00017	$0.00328
Haiku 4.5	$0.00009	$0.00164

Security

Grade A, and why

headless-ghidra 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.

The scan reads SKILL.md. This mod also ships 10 executable files (examples/artifacts/sample-target/regenerate-project.sh, frida-scripts/call-tree-trace.js, frida-scripts/decomp-compare.js, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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 ships with it

56 files 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.

Changes

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.

headless-ghidra is a skill published in the GitHub repository ByteLandTechnology/headless-ghidra (5 stars, last pushed 4mo ago), with no licence file. It adds 87 tokens to every session and 1,638 once invoked, about $0.0004 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 2026-08-31.
