pprose

Practical Prose tooling: deterministic metrics, rubric scoring, evaluation reports, and comparisons for practical documents.

pprose is the command-line companion to Practical Prose, a reference system and evaluation toolkit for writing that helps a reader understand, decide, do, verify, or maintain something.

Install

The distribution and command are both pprose. After publication, run with no install using uv:

uvx pprose <command> ...

Or install it:

uv tool install pprose

Commands

pprose metrics doc.md                              # deterministic metrics for a document
pprose report from-metrics doc.md --out doc.eval.md  # build an eval report stub
pprose score doc.eval.md --model opus              # LLM rubric scoring (Anthropic, OpenAI, or Google)
pprose compare a.eval.md b.eval.md                 # compare N eval reports
pprose render doc.eval.md                          # render an eval report as static HTML

pprose about                                       # the project narrative (bundled README)
pprose skill                                       # workflow skills overview + routing pointers
pprose list                                        # every bundled guideline, shortcut, runbook, skill
pprose guidelines <name>                           # print one style guide (no name lists them)
pprose install                                     # install skills into the current project
pprose install --global                            # install skills user-wide for every project

pprose install runs in one of two scopes:

• Project (--project, the default when cwd is inside a git repo) writes into <repo>/.agents/skills/ (Codex, Gemini CLI, pi), <repo>/.claude/skills/ (Claude Code), and a marker-bounded block in <repo>/AGENTS.md.
• User-global (--global) writes into ~/.agents/skills/pprose-*/ and ~/.claude/skills/pprose-*/, making the skills available across every project. Skips ~/.codex/AGENTS.md so the global instruction file stays user-authored.

Outside an unambiguous project context ($HOME, a non-git directory), --project or --global must be passed explicitly; there is no silent default. $HOME is always refused under --project; use --global for a user-wide install. Pass --surfaces=portable,claude,agents-md (or --surfaces=all, the default) to select install destinations within the chosen scope, or --pin <version> to override the version baked into the bootstrap line.

Every generated artifact carries a format=fNN stamp; re-running install is idempotent, and a newer-format artifact is never clobbered by an older pprose. Each generated skill bakes in a pinned, local-first invocation (pprose if on PATH, else uvx pprose@<version>). Cross-scope coexistence is the supported pattern: project-scope skills shadow user-scope skills of the same name in modern agents. Run pprose --help or pprose install --help for full options.

Upgrading: new releases can add guidelines, shortcuts, runbooks, and skills. Because installed skills pin the version that installed them, a repo picks up additions only after you upgrade pprose and re-run install (uvx pprose@latest install, or uv tool install --upgrade pprose && pprose install); re-running refreshes both the artifacts and the baked version pin.

score requires the API key for the chosen provider (ANTHROPIC_API_KEY, OPENAI_API_KEY, or GOOGLE_API_KEY); the package auto-loads .env and .env.local from the current directory hierarchy and $HOME.
