@kompiro/tpl-tools

Frontmatter-driven Test Perspective Library (TPL) validator and query tool. Extracted from kompiro/karasu.

A TPL is a markdown file with YAML frontmatter recording a recurring test-perspective (typically distilled from a past bug) so the same class of defect is caught earlier next time. This package validates a directory of such files, lets you query them by topic/package, and renders the body for a periodic deprecation-review issue.

Install

Published to the public npm registry:

pnpm add -D @kompiro/tpl-tools

Standalone binary (no Node required)

For environments without a Node toolchain (other projects, Go/other-language devcontainers, etc.), install the self-contained executable published to GitHub Releases:

curl -fsSL https://raw.githubusercontent.com/kompiro/tpl-tools/main/install.sh | sh

The script detects your OS/arch, downloads the matching binary, verifies its SHA256, and installs it to ~/.local/bin/tpl. Override with TPL_VERSION (release tag) or INSTALL_DIR. In a devcontainer, add the one-liner above as a RUN step in your Dockerfile — alongside the adr-tools installer if you use both.

CLI

tpl <subcommand> [options]

  init           generate a starter tpl.config.json in the target dir (or CWD)
  validate       validate TPL frontmatter, filenames, cross-refs, README index
  related        list active TPLs matching a topic (markdown for Design Docs)
  review-body    print the body for a periodic TPL deprecation-review issue

Configuration (tpl.config.json)

tpl reads reference data — the controlled topics vocabulary and the idFormat — from a JSON file. Resolution order:

1. an explicit --config <path> (highest priority)
2. tpl.config.json in the working directory, when present
3. none — topic validation is skipped and the default id format is used

This lets tpl run standalone (its own tpl.config.json) or reuse a shared file in a repo that also uses adr-tools by pointing --config at adr.config.json (extra keys are ignored). Run tpl init to scaffold one. The generated file's $schema points at the npm package path, so editor autocompletion resolves when the package is installed.

tpl init

tpl init [dir]

Writes a starter tpl.config.json (defining topics and idFormat) to dir (default: CWD). Refuses to overwrite an existing file.

tpl validate

tpl validate [--tpl-dir <path>] [--config <path>] [--packages-root <path>]

• --tpl-dir — directory of TPL files (default docs/test-perspectives)
• --config — JSON file holding topics (controlled vocabulary, optional) and idFormat (optional, see below). Defaults to tpl.config.json in CWD when present; omit and provide no tpl.config.json to skip topic validation and use the default id format.
• --packages-root — directory whose immediate subdirectories are the allowed values for scope.packages. Omit to skip that check (non-monorepo repos).

Exit code 0 = clean, 1 = findings, 2 = usage / I/O error.

idFormat

The config JSON may include an idFormat field that selects the TPL id and filename convention:

Value	Filename	Frontmatter id
date-sequence (default)	TPL-YYYYMMDD-NN-<slug>.md	TPL-YYYYMMDD-NN
issue-number	TPL-<n>-<slug>.md (no zero padding)	TPL-<n>

Under issue-number, <n> is typically the originating GitHub Issue or PR number; common numbering policy is Issue number → PR number → local sequence (existing max + 1). Pick one format per project; mixing in one corpus is not supported.

{
  "idFormat": "issue-number",
  "topics": ["frontend", "api", "data"]
}

tpl related

tpl related <topic> [--package <pkg>] [--tpl-dir <path>] [--config <path>] [--path-prefix <p>]

Prints a markdown bullet list of active TPLs matching <topic>, ready to paste into a Design Doc's "Related TPLs" section.

tpl review-body

tpl review-body [--tpl-dir <path>] [--repo <owner/repo>] [--tpl-dir-relative <p>]

Prints the markdown body for a periodic TPL deprecation-review issue to stdout (--repo defaults to $GITHUB_REPOSITORY). Typically piped into gh issue create --body-file -.

Reference templates

This repo ships starter templates you can copy into your project:

• docs/test-perspectives/TEMPLATE.md — frontmatter + body skeleton for a new TPL
• docs/test-perspectives/README.md — index, ADR との違い、proactive / retrospective、3-Yes ルール、ライフサイクル、運用ノート

For a fully populated example corpus, see karasu's docs/test-perspectives/.
