    setup-ts-deep-modules

    Wire dependency-cruiser into a TypeScript repo so each package is a deep module — implementation hidden in subfolders, reachable only through its entry-point files. User-invoked.

The file

We split this skill into the rules it gives an agent

8 rules. 0 are common, 6 are distinctive, and 2 are very specific to this project.

  • 0

    Common

    Most of the 171 edited versions we read keep these.

  • 6

    Distinctive

    This author's own choices. Worth a look.

  • 2

    Very specific

    Tied to their project's names, files or tools. Probably skip.

  • Common
  • Distinctive
  • Very specific
  1. Distinctive:

    If no arguments, look for the most recently discussed plan in the conversation.

    line 17
  2. Distinctive:

    If no plan exists, STOP and tell the user: "No plan found.

    line 27
  3. Distinctive:

    Read relevant COMP files (CLAUDE.md for conventions, MEMORY.md for gotchas)

    line 31
  4. Distinctive:

    If a sub-task fails or hits an unexpected issue, STOP and report to the user rather than improvising a workaround

    line 46
  5. Very specific:

    After each subagent returns, validate the report.

    line 48
  6. Distinctive:

    Check the plan's success criteria:

    line 51
  7. Distinctive:

    Run tests if applicable

    line 52
  8. Very specific:

    After implementation completes, /verify is mandatory -- not optional.

    line 60

“Common” is measured: kept by at least 6 in 10 of the 171 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.

Implementation Agent

Execute a plan that has already been designed and approved. This is the "do" phase -- no redesigning.

Input

Plan to implement: $ARGUMENTS

If no arguments, look for the most recently discussed plan in the conversation.

Process

Step 1: Locate the Plan

Find the plan to implement. Sources:

  • Explicitly provided in arguments
  • Most recent /plan-task output in conversation
  • Project PLAN.md

If no plan exists, STOP and tell the user: "No plan found. Run /plan-task first, or describe what to implement."

Step 2: Verify Prerequisites

Before starting:

  • Read relevant COMP files (CLAUDE.md for conventions, MEMORY.md for gotchas)
  • Confirm all dependencies are met
  • Identify any sub-tasks that can run in parallel

Step 2.5: Triage Complexity

Assess the plan's scope and choose execution strategy:

  • Trivial (single file, well-understood): Execute directly, skip subagents. Don't waste tokens on delegation overhead.
  • Small (few files, clear spec): Execute directly or single subagent.
  • Large (multi-file, cross-cutting, research needed): Decompose into sequential subagent dispatches with verification between each.

Step 3: Execute Sub-Tasks

Work through the plan's sub-tasks in order:

  • For parallelizable tasks, use multiple Agent calls in a single message
  • For each sub-task, verify completion before moving to the next dependent task
  • If a sub-task fails or hits an unexpected issue, STOP and report to the user rather than improvising a workaround

After each subagent returns, validate the report. See ~/.claude/skills/implement/subagent-validation.md for the full protocol.

Step 4: Verify Success

Check the plan's success criteria:

  • Run tests if applicable
  • Generate visualizations if the plan called for them
  • Spot-check outputs against expected values

Report results to the user.

See ~/.claude/skills/implement/rules.md for implementation guardrails.

After implementation completes, /verify is mandatory -- not optional. The /wrapup health check will flag sessions where /implement ran without /verify.

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.
