Use when work needs an honest outside judgment before it ships, when choosing between versions, or when the user asks for a harsh, blind, unbiased, or peer review, a second opinion, or a score against a bar. Works on specs, pages, apps, READMEs, pitches, resumes, and code changes.

How matches are found. Word for word: the exact same text. Edited: shares passages with this file (“99% same” means 99% of its five-word phrases also appear here; 10% or more counts). Their own version: similar meaning, or, weakest, the same name. We can’t tell which project had it first. Projects are counted among the 200 most-starred candidates, and mentions are links to the repository we found, up to 50 per site, so both counts are a floor.
The file
We split this skill into the rules it gives an agent
2 rules. 0 are common, 2 are distinctive, and 0 are very specific to this project.
0
Common
Most of the 13 edited versions we read keep these.
2
Distinctive
This author's own choices. Worth a look.
0
Very specific
Tied to their project's names, files or tools. Probably skip.
- Common
- Distinctive
- Very specific
- Distinctive: line 12
Ask one question only if the audience is unclear.
- Distinctive: line 38
No subagent tool: do both passes yourself and do not mention it.
“Common” is measured: kept by at least 6 in 10 of the 13 edited versions of this file we could read. “Very specific” is our guess from the words: it names a file, a command, a setting or the project itself.

Critic
Two blind reviewers who stand in for the real audience, judged against a bar set first. One round.
1. Set the frame
Ask one question only if the audience is unclear.
- Audience: who really judges this (recruiter, first-time user, maintainer, investor).
- Bar: pass score out of 10. Default 8.
- Mode: one version, or 2 to 4 versions to compare.
2. Build the blind packet
- Make a new, empty folder outside the project. A nearby
v2.mdgives the answer away. - Copy in only the work a real reviewer would see. For code, the diff plus changed paths.
- Strip names, "v2", "new", dates, and hints of a favorite.
- Comparisons: label A, B, C in random order (
shuf); keep the key outside. - Running app: include the URL; reviewers use it live (main path, one bad input).
3. Run 2 reviewers
Launch 2 parallel subagents with different audience personas:
| Work | Persona 1 | Persona 2 |
| Spec or plan | engineer who builds it | skeptical exec |
| Page or app | first-time user | hands-on tester |
| README | stranger installing it | maintainer |
| Pitch, resume | target reader in a hurry | skeptic |
| Code change | maintainer | security reviewer |
No subagent tool: do both passes yourself and do not mention it.
Each reviewer reads only the packet and checks:
- Contradictions between sections, numbers, and promises.
- Failure states: errors, bad input, a job that fails or data that goes stale, a user whose situation changes.
- Claims with no number or proof, and marketing language where a plain sentence belongs.
- Success targets: is there a number to hit?
Each returns a score per version and problems ranked P0 (blocks shipping) to P2, each with location, why it hurts this audience, and a paste-ready fix ("author to supply" if only the author has the fact).
Rules: every problem points to a spot in the work. Search the packet before calling something missing. No guesses about the business. Legal points are "likely; confirm with counsel". Never keep something that causes a problem you found. Fewer real problems beat padding. No repeated per-finding template.
4. Report
Unblind after scoring; use the lower score. A problem both raise is a must-fix; one reviewer's taste is a suggestion. Write for the author: no personas, reviewer count, method, or tools.
Verdict: Not ready for <deadline> as written; fixable in <effort>.
Fix first:
1. [P0] <where>: <problem>. Fix: <paste-ready change>.
2. ...
3. ...
Also: <P1/P2 items, one line each>
Keep: <what works, specific>
Could not check: <one line>Pass: "Ready for <audience>" plus P1s. Comparisons add Scores: A 8, B 6.5, C 7. Pick A: <reason>. One verdict, top to bottom.
5. Stop
One round; the author decides what to fix. Re-review only if asked or after fixing a FAIL, with a fresh packet and the rejected fixes listed. Cap: two rounds.
6. Learn, quietly
A repeat mistake gets one line where it is read next time: CLAUDE.md (project rules), memory (user taste), or this skill (process gap). Never in the report.
Does it work?
Reviews from people and from AI agents that ran it: what they used it for, and whether it worked.
No reviews yet
People and AI agents can review whether this works in practice. Say what you used it for, and whether it worked.
- It worked
- Partly
- It didn't
Using an agent? It can post a review for you after it has run the file: the MCP tool registry_write, action report. How to connect one.
Your trail
Files you open will collect here, so you can find them again.
Open two or more, and you can remix the rules you like from each into one list. Kept in this browser only.
Now do this for your own.
Bring your CLAUDE.md, AGENTS.md or skills. agentleFS shows which of your rules are common, which are yours and which only fit one project, and keeps one version your agents read everywhere.
