We split this skill into the rules it gives an agent

4 rules. 0 are common, 4 are distinctive, and 0 are very specific to this project.

  • 0

    Common

    Most of the 12 edited versions we read keep these.

  • 4

    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
  1. Distinctive:

    Make the trace reconstructable: When output is wrong, you need to see which agent decided what, with what input.

    line 20
  2. Distinctive:

    NEVER weaken or skip a failing test to make a change land.

    line 38
  3. Distinctive:

    NEVER swallow errors silently or leave unhandled rejections in production paths.

    line 39
  4. Distinctive:

    NEVER introduce a breaking API change without a version bump and migration path.

    line 40

“Common” is measured: kept by at least 6 in 10 of the 12 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.

Keep what fits and drop the rest. Your version, ready for your agents.

Agent Architecture

Design multi-agent systems where coordination does not become the failure mode.

Process

  1. Justify the second agent. Most tasks that look multi-agent are one agent with better tools. Split only when roles need genuinely different context or run concurrently.
  2. Decompose by context boundary, not by job title. An agent exists to hold a distinct working set, not to mirror an org chart.
  3. Define the contract between agents — the exact shape of what is passed, and what is guaranteed about it. Free-text handoff is where multi-agent systems lose information.
  4. Decide where state lives. Shared mutable state between agents needs the same care as between threads.
  5. Isolate failure. One agent failing or looping must not stall the others; set timeouts and a supervisor that can terminate.
  6. Make the trace reconstructable. When output is wrong, you need to see which agent decided what, with what input.
  7. Bound the total cost. Agents that can spawn agents need a hard ceiling.

Deliverables

  • Role decomposition with the context boundary justifying each agent
  • Message contracts between agents
  • Failure isolation, timeouts and supervision model
  • Trace format and cost ceiling

Verification & Quality Checklist

  • Code compiles and all automated tests and typechecks pass without new warnings.
  • Edge cases, boundary conditions, and error states handled explicitly rather than assumed.
  • No hardcoded secrets, credentials, or insecure defaults introduced.
  • Changes are covered by a test that fails without them.

Anti-Patterns & Constraints

  • NEVER weaken or skip a failing test to make a change land.
  • NEVER swallow errors silently or leave unhandled rejections in production paths.
  • NEVER introduce a breaking API change without a version bump and migration path.

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
What did you use it for? e.g. Reviewing pull requests in a Rails app

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.
