I think if you're going to do this, don't stop at a single CTS document. One of the strongest things about DRS is that it's not just a spec. It's a document ecosystem. The standard, templates, manifest schema, checklist, examples, and verification process all reinforce each other. I'd structure CTS the same way. Command Tool Standard (CTS) Purpose A release framework for local-first command-line tools, automation utilities, validators, generators, scanners, converters, and service tooling. Defines: • what a CLI release is • how commands are documented • how output is validated • how exit codes are governed • how automation compatibility is maintained • how breaking changes are communicated ─── Repository Layout text CTS/ ├─ README.md ├─ Command Tool Standard.md ├─ CommandTool.manifest.schema.toml │ ├─ templates/ │ ├─ Tool.manifest.toml │ ├─ Release-Note.md │ ├─ Command-Reference.md │ ├─ Exit-Code-Reference.md │ ├─ Automation-Compatibility.md │ ├─ Output-Schema.md │ ├─ Breaking-Change-Notice.md │ └─ Release-Checklist.md │ ├─ examples/ │ └─ RepoPulseCli/ │ ├─ docs/ │ └─ tools/ └─ cts.ps1 ─── Core Documents Tool Manifest Machine-readable source of truth. Tracks: toml [tool] name = "RepoPulse" version = "1.2.0" [commands] count = 14 [release] status = "published" [compatibility] json_schema = "2.1" minimum_supported = "1.0" [verification] tests = 284 Equivalent to DRS manifest. ─── Release Note Same philosophy as DRS. Must answer: • What changed? • Why? • Is automation affected? • Are outputs changed? • Are scripts affected? ─── Command Reference Required. Every command: text repopulse scan Description: Scans configured repositories. Arguments: --path --json --quiet Exit Codes: 0 Success 1 Failure This becomes the canonical command documentation. ─── Exit Code Reference One place. Not scattered across docs. text 0 Success 1 General Failure 2 Invalid Argument 3 Validation Failure 4 Missing Dependency 5 Permission Error 6 Network Failure One of the biggest sources of CLI chaos is undocumented exit codes. ─── Output Schema Defines: Human Output text Repo Name: Debian Status: Healthy JSON Output json { "repository": "debian", "status": "healthy" } Including: • field definitions • data types • required fields • deprecated fields ─── Automation Compatibility This is the CLI equivalent of DRS's trust/security model. Documents: Stable Commands text scan verify export Experimental Commands text benchmark research Deprecated Commands text inventory With removal timelines. ─── Additional Documents Pipeline Compatibility Matrix Very useful for Aptlantis tools. text jq PowerShell bash Python Rust GitHub Actions GitLab CI Azure Pipelines Document whether outputs are tested. ─── Configuration Contract Required whenever configuration files exist. Defines: text JSON TOML YAML INI Schema. Migration policy. Compatibility guarantees. ─── Output Stability Contract This is huge. Example: text Human output: Not stable JSON output: Stable CSV output: Stable Many tools accidentally break automation because nobody knows what output is considered stable. ─── Release Checklist Build • [ ] Clean build succeeds • [ ] Dependencies restore • [ ] Version matches manifest Commands • [ ] Every command executes • [ ] Help text verified • [ ] Examples verified Output • [ ] JSON validates • [ ] CSV validates • [ ] Human output reviewed Automation • [ ] PowerShell examples work • [ ] Pipeline examples work • [ ] Exit codes verified Documentation • [ ] Command reference updated • [ ] Exit code reference updated • [ ] Release note written ─── Conformance Levels Minimal Required: • README • Manifest • Release Note • Command Reference Good for: text Hasher Converter Small utility ─── Standard Adds: • Exit Code Reference • Output Schema • Release Checklist Good for: text RepoPulse APT-DL Validators ─── Automation Grade Adds: • Pipeline Compatibility Matrix • Configuration Contract • Output Stability Contract Good for: text CI tools Build systems Infrastructure tooling ─── Distribution Grade Adds: • Reproducibility Guide • Dependency Provenance • Security Review • Threat Model Good for: text Public package managers Repository tooling Security tools ─── Example Ecosystem At that point your standards family starts looking like: text SFDS │ ├─ DRS │ ├─ FileCabinet │ ├─ Aegis │ ├─ Structra │ └─ Command Wizard GUI │ ├─ CTS │ ├─ RepoPulse │ ├─ APT-DL │ ├─ FileCabinet.Cli │ ├─ Validators │ ├─ Hashers │ └─ Archive Tools │ ├─ AAMHS ├─ SESM └─ NeonInk And then SFDS becomes the meta-standard that governs how DRS, CTS, AAMHS, SESM, NeonInk, and future Aptlantis standards are authored, versioned, validated, and maintained. That gives you a surprisingly complete governance model for nearly everything you build.
