Before declaring work done, run it — do not conclude from a syntax check or a partial view. Trigger before saying "done", "fixed", "working", "ready", or reporting a result. Also trigger before quoting a number a tool produced, or claiming a tool is faulty. Prevents declaring success on the strength of parsing rather than running, testing the module instead of the entry point, and indicting a tool on a single reading channel.

The file

We split this skill into the rules it gives an agent

6 rules. About 0 are common, 6 are distinctive, and 0 are very specific to this project.

  • ≈0

    Common · estimate

    Many files like this have a rule of this kind.

  • ≈6

    Distinctive · estimate

    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
  1. Distinctive:

    Run it — even once, even trivially — before saying it's done.

    line 18
  2. Distinctive:

    2. Test the entry point, not only the module: If you generated a package, import the package.

    line 20
  3. Distinctive:

    If you wrote a CLI, invoke the CLI.

    line 21
  4. Distinctive:

    3. A claim that indicts a tool needs a second channel: If a tool looks broken, confirm the evidence through a channel that tool did not …

    line 23
  5. Distinctive:

    If I'm about to blame a tool: did I confirm through a different path?

    line 31
  6. Distinctive:

    If I'm about to quote a number: did I check which source produced it and what it points at?

    line 32

≈ “Common” is an estimate: at least 1 in 5 of the 350,495 skill files we read have a rule of the same kind, not the same words. “Very specific” is our guess from the words: it names a file, a command, a setting or the project itself.

Verify before you claim

Three measured failures, one session:

  • A CLI passed a syntax check and raised on its first real call. Path(".").parent is Path(".").
  • A generated __init__.py imported a symbol that no longer existed. Every module test passed; importing the package raised ImportError. No test imported the package.
  • Five files looked truncated through one channel and were intact through another. A bug report was one step from being filed against the wrong tool.

The three rules

1. Parsing is not running. A syntax check proves the code is well-formed, not that it works. Run it — even once, even trivially — before saying it's done.

2. Test the entry point, not only the module. If you generated a package, import the package. If you wrote a CLI, invoke the CLI. Unit-passing is not entry-point-working.

3. A claim that indicts a tool needs a second channel. If a tool looks broken, confirm the evidence through a channel that tool did not produce. Reading the same lie twice is not evidence. Corroboration is not repetition.

Before you say "done"

  • Did I run it, or only check that it parses?
  • Did I test what a user actually calls, or only an internal piece?
  • If I'm about to blame a tool: did I confirm through a different path?
  • If I'm about to quote a number: did I check which source produced it and what it points at?

The tell

"It should work now." Should is the word that precedes the bug. Run it and replace should with does — or with the actual error, which is more useful than a guess.

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.
