Com Proxy Triage

What it does

When your agent uses it

• Mapping each CLSID to the machine-wide HKLM\SOFTWARE\Classes\CLSID\{...}\InProcServer32 DLL
• Optionally testing HKCU overrides with a Koppeling-style proxy DLL

Example prompts

• “/com-proxy-triage”

Workflow steps

7 steps, taken from the first numbered list in SKILL.md.

1. 1Run the watcher from an elevated PowerShell session and filter to the target process with -ProcessName.
2. 2Keep only HKCU InProcServer32 misses where MachineInprocServer32 is present.
3. 3Deduplicate by Clsid.
4. 4Build or reuse a proxy DLL that clones the HKLM target DLL's exports and runs the chosen payload.
5. 5Override HKCU\Software\Classes\CLSID{CLSID}\InProcServer32, launch a fresh target process, and check whether the payload fired.
6. 6Restore the prior HKCU state after every test. If the key did not exist before, remove it.
7. 7Resolve installed apps by name first. Use assets\apps.json as an override cache when present, not as a required source of truth.

What it can do on your machine

Read from SKILL.md and the folder at commit e655f93. It shows what the files ask for, not the result of running them.

• Tool permissions

  Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

  From allowed-tools in the SKILL.md frontmatter.

• Runs code

  Ships 1 file in scripts/, which the agent can run.

  From the folder's file list and the shell code blocks in SKILL.md.

• Network

  No URLs in SKILL.md.

  From URLs in SKILL.md, links to its own repository left out.

• Credentials

  Names no API keys, tokens, secrets or passwords.

  From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Com Proxy Triage loads about 1.5k tokens when it runs, and up to ~2.1k if it reads all its reference files. Until then it costs about 106 tokens; SKILL.md has 578 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it

~106

When it runs · the whole SKILL.md, loaded when a task matches

~1.5k

With references · SKILL.md plus every file in references/, read only if the agent opens them

~2.1k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); the scripts in this folder are not scanned.

description

Use this skill when the user wants to triage Windows COM proxy/hijack candidates by capturing `HKCU\Software\Classes\CLSID\{...}\InProcServer32` `NAME NOT FOUND` lookups for a process, mapping each CLSID to the machine-wide `HKLM\SOFTWARE\Classes\CLSID\{...}\InProcServer32` DLL, and optionally testing HKCU overrides with a Koppeling-style proxy DLL. Good for Zoom, Edge, and similar COM activation hunts.
