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 | $0.00065 | $0.00679 |
| Opus 5 | $0.00032 | $0.00340 |
| Sonnet 5 | $0.00013 | $0.00136 |
| Haiku 4.5 | $0.00006 | $0.00068 |
Grade A, and why
analyzing-golang-malware-internals 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.
What it actually says
Analyzing Golang Malware Internals
When to Use
- You have a Go-compiled binary (often large, statically linked) and standard symbol recovery fails because user symbols are stripped.
- You need function names from the pclntab, the Go version, and embedded package/module paths.
Do not use this for non-Go binaries — confirm the Go build signature first. This skill reads the binary statically and executes nothing.
Prerequisites
- The Go binary (read inertly).
Safety & Handling
- Read bytes statically; treat strings as untrusted data.
Workflow
Step 1: Confirm it is Go and get the version
python scripts/analyst.py info sample.bin
Looks for the Go build ID, the go1.x version string, and runtime. references.
Step 2: Recover function names from pclntab
The pclntab (preceded by a magic like \xfb\xff\xff\xff/\xf0\xff\xff\xff across Go versions)
contains function name strings; extract main.*, package-qualified, and runtime.* names.
Step 3: Enumerate package paths
List embedded import/module paths (github.com/..., vendored deps) to fingerprint capabilities
and third-party libraries.
Step 4: Map and document
Map suspicious packages (networking, crypto, exec) to behavior and ATT&CK.
Validation
- The Go build signature/version is confirmed before deeper parsing.
- Recovered names include plausible
main.*/package-qualified functions. - Package paths are real module paths, not random strings.
Pitfalls
- pclntab magic differs across Go versions; try the known set.
- Obfuscators (garble) rename symbols and strip build info — names may be hashed.
- Confusing vendored library code with the author's
mainpackage.
References
- See
references/api-reference.mdfor the analyzer. - Go pclntab/buildinfo references (linked in frontmatter).
What ships with it
3 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.
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.

analyzing-golang-malware-internals is a skill published in the GitHub repository meltedinhex/analyst-ai-pack (22 stars, last pushed 2mo ago), licensed Apache-2.0. It adds 65 tokens to every session and 679 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.
