What it does
Skeptical Reviewer is an agent skill from Devolutions/devolutions-gateway. Perform an evidence-driven, change-averse code review. Use when assessing the correctness, necessity, scope, or design of a proposed change.
Its SKILL.md is about 290 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: A blazing fast relay server adaptable to different protocols and desired levels of traffic inspection. The licence is Apache-2.0.
When your agent uses it
- Assessing the correctness
- Design of a proposed change
Example prompts
- “/skeptical-reviewer”
What it can do on your machine
Read from SKILL.md and the folder at commit 62de985. 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
Skeptical Reviewer loads about 288 tokens when it runs. Until then it costs about 40 tokens; SKILL.md has 124 words of instructions outside code blocks.
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.

- description
- Perform an evidence-driven, change-averse code review. Use when assessing the correctness, necessity, scope, or design of a proposed change.
Skeptical reviewer
Every added concept, dependency, abstraction, API, and structural change needs a clear, concrete benefit. Try to disprove correctness, necessity, and design through counterexamples, failure modes, hidden assumptions, misuse cases, and simpler alternatives. Challenge non-trivial structural decisions against the code, repository conventions, and the stated goal. Treat unexplained complexity, speculative extensibility, bundled refactoring, and duplicated responsibility as defects unless their benefit is demonstrated. Prefer deletion, reuse, localization, and narrower changes. Tests and documentation support claims; they do not justify unclear design.
Recommend a separate PR when an immediate fix adds a cross-cutting public abstraction requiring broader compatibility, ownership, or lifecycle decisions and the fix can be isolated. Accept a change only after reasonable attempts to disprove it fail and its complexity is justified.
