Analyze IronRDP changes for RDP protocol conformance against Microsoft Open Specifications.

  • Reviewing protocol behavior
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md
  • Virtual channels
  • Capability negotiation

What it does

Protocol Reviewer is an agent skill from Devolutions/IronRDP. Analyze IronRDP changes for RDP protocol conformance against Microsoft Open Specifications. Use when reviewing protocol behavior, wire formats, PDUs, virtual channels, codecs, security, capability negotiation, or protocol-visible errors.

Its SKILL.md is about 550 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Development. The repository describes itself as: Rust implementation of the Microsoft Remote Desktop Protocol (RDP). The licence is Apache-2.0.

When your agent uses it

  • Reviewing protocol behavior
  • Virtual channels
  • Capability negotiation
  • Protocol-visible errors

Example prompts

  • “/protocol-reviewer”

What it can do on your machine

Read from SKILL.md and the folder at commit 2c08bda. 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

    No scripts in the folder and no shell commands in SKILL.md.

    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

Protocol Reviewer loads about 548 tokens when it runs. Until then it costs about 64 tokens; SKILL.md has 233 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~64
When it runs · the whole SKILL.md, loaded when a task matches
~548

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

Auto-check passed

The automated check found no risky patterns in SKILL.md.

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); files beside SKILL.md are not scanned.

Protocol reviewer

Use the windows-protocols skill when it is available to consult the local Microsoft Open Specifications corpus. If it is unavailable, use the Microsoft Learn MCP server when configured: search with microsoft_docs_search, then retrieve relevant learn.microsoft.com/openspecs pages with microsoft_docs_fetch. If neither source is available, use another authoritative specification source provided in the task and state any resulting evidence gap.

Keep the review focused on protocol conformance rather than general code quality. Identify changed wire formats, PDUs, fields, constants, state transitions, capability negotiation, security behavior, virtual channels, codecs, and protocol-visible errors. First decide whether the change is materially protocol-related; do not force a protocol review onto an unrelated change.

Identify the governing requirements before judging the implementation. Start from the relevant overview when the protocol ID is uncertain, then follow base, extension, and shared-type references. Check versioning, capability negotiation, sequencing, security, and product-behavior sections when applicable.

Map each protocol-relevant change to its requirement and attempt to falsify compliance: field order, width, signedness, constants, reserved values, optional fields, lengths, bounds, encode/decode symmetry, malformed-input handling, state-machine transitions, ordering, error paths, compatibility guards, endpoint roles, security requirements, and undocumented interoperability assumptions.

Separate normative requirements from informative text, product-specific behavior, and inference. Cite the governing source precisely and make uncertainty explicit when the corpus is inconclusive. Do not infer a requirement merely because an implementation pattern is conventional or propose architectural refactors unless the specification requires them.
