Claude Code mod

test-gardener

Makes Claude consolidate tests instead of appending them. After it writes or edits a test file, a note names the test files that already cover the module, the near-duplicates and clones among the tests it just added, and a file past the size guideline; a tests_neighbourhood tool answers the same before tests are written; /tests audit lists the consolidations for the project (clones, near-duplicates, parametrize candidates, oversized files, skips, tests whose module is gone) and suggests executing them; a band above the prompt flags a branch heavy with new tests. Never edits a test, blocks nothing, makes no model calls.

How Claude Code mods work

  • A mod is a plugin with a JavaScript or TypeScript module that runs inside Claude Code (version 2.1.287 or later). It can draw panes beside the transcript, a band above the prompt, buttons and toasts, restyle the spinner and tool rows, and watch or rewrite tool calls and prompts.
  • It installs like any plugin: add its marketplace with /plugin marketplace add owner/repo, then /plugin install name@marketplace.
  • Check what a mod can reach before installing: it runs with your permissions. Reach goes from drawing only, to reading files, to writing files or running processes, to the network. Run claude plugin validate on a clone to list its hooks and calls without running it.
  • Turn one off from the Installed tab in /plugin, or start Claude Code with --safe-mode to skip every customization for a session.

leeovery/portal

Draws the transcript rows of what the workflow-gates mod sends — an answer as the question it answered and the answer, a handoff's continuation as where the work went — and a compaction's note as one dim line, instead of Claude Code's framing.

Memory & instructions mods

recall

3

joeldg/claude-mods

Makes past sessions recallable: indexes Claude Code and Codex transcripts, subagent runs, memory files, standing orders and second-opinion reviews into a local SQLite index (kept after Claude Code deletes old transcripts), gives Claude search, expand, recap and list tools, and adds /recall (search, last session, timeline, decisions, commands, files, PRs, ask), /remember, a pick-up-where-you-left-off band, a related-work band, and a per-session ledger (goal, open tasks, questions answered, files touched, PRs and commits) that comes back after a compaction and /recall ledger prints. Nothing calls a model except /recall ask: one call to the ask model per question, billed to your usage.
