Portable repository-scoped skill: Reduce an ambiguous technical problem to verified facts, constraints, and explicit decisions before proposing a solution. Defined entirely by SKILL.md. - SKILL.md — canonical definition: frontmatter (name: first-principles, description), a six-step workflow (outcome → separate facts from assumptions → decompose → verify decision-changing facts → rebuild → record trade-offs), and the required decision-record output (objective, facts, constraints, assumptions, options, chosen design, risks, verification evidence). - README.md — human signpost. - Claude Code wrapper: .claude/skills/first-principles/SKILL.md only points back…
Where files are headingNew AGENTS.md files have more rules about keeping secrets out of the code, and fewer about code style.
Of the AGENTS.md files we read, the 31,700 first seen in the last six months, against the older ones: the kind of rule that gained most share, and the kind that lost most. About files like this in general, not this one, and an estimate, since a kind is a pattern in the words.
In this repository47 other files it gives its agents.

The file
We split this AGENTS.md into the rules it gives an agent
2 rules. About 0 are common, 1 is distinctive, and 1 is very specific to this project.
≈0
Common · estimate
Many files like this have a rule of this kind.
≈1
Distinctive · estimate
This author's own choices. Worth a look.
1
Very specific
Tied to their project's names, files or tools. Probably skip.
- Common
- Distinctive
- Very specific
- Distinctive: line 31
Use when a request is ambiguous or a design has accumulated unexamined assumptions.
- Very specific: line 34
Keep name equal to the folder name.
≈ “Common” is an estimate: at least 1 in 5 of the 40,246 AGENTS.md 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.
Files
AGENTS.md — codomyrmex/.agents/skills/first-principles
Purpose
Portable repository-scoped skill: Reduce an ambiguous technical problem to
verified facts, constraints, and explicit decisions before proposing a
solution. Defined entirely by SKILL.md.
Key Files
SKILL.md— canonical definition: frontmatter (name: first-principles,description), a six-step workflow (outcome → separate facts from assumptions → decompose → verify decision-changing facts → rebuild → record trade-offs), and the required decision-record output (objective, facts, constraints, assumptions, options, chosen design, risks, verification evidence).README.md— human signpost.
Dependencies
- Claude Code wrapper:
.claude/skills/first-principles/SKILL.mdonly points back to this file. - Codex discovers it from
.agents/skills/; Hermes viaskills.external_dirs. - First step of the composition order in
docs/agents/agent-interoperability.md;
its decision record feeds
systems-thinking. - Parent: ../AGENTS.md
Development Guidelines
- Use when a request is ambiguous or a design has accumulated unexamined assumptions.
- This is the canonical copy; runtime wrappers such as
.claude/skills/first-principles/stay pointers — change the workflow here. - Keep
nameequal to the folder name; a rename must also update the wrapper,.agent/SKILL_INDEX.md, and the interoperability doc. - Preserve the rule that an assumption is never presented as a fact, and keep the decision-record fields stable so downstream skills can rely on them.
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.
