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 | $0.00080 | $0.00304 |
| Opus 5 | $0.00040 | $0.00152 |
| Sonnet 5 | $0.00016 | $0.00061 |
| Haiku 4.5 | $0.00008 | $0.00030 |
Grade A, and why
dotnet-decompile 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 4d 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
.NET Decompiler
Decompile a .NET / CLR assembly (IL) back to C# with
ilspycmd.
When to use
A managed .NET assembly you need to read. Run dotnet-analyze first for the shape
and P/Invoke surface, then this for full C#.
What it does
Runs ilspycmd <assembly> -o <outdir> (static — reads IL/metadata, never runs the
assembly) and reports the files written.
Prerequisites
- python3 (runner) and
ilspycmdon PATH — a dotnet tool that needs the .NET runtime, so it is not bundled:dotnet tool install -g ilspycmd. Until thendoctormarks the skill not-ready andrunreports the honest blind spot.
Usage
rekit run dotnet-decompile ./managed.dll ./out
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.

dotnet-decompile is a skill published in the GitHub repository batteryshark/rekit (11 stars, last pushed 26d ago), licensed Apache-2.0. It adds 80 tokens to every session and 304 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 2026-08-30.
