co sits next to std under packages/, not inside it. std is the low-level standard library: roles, patterns, output adapters, memory, evals, and ops primitives. co is an opinionated starter kit for a specific domain: a company whose operating system is made of Prose services and systems.

Reference services and systems in co with the co/ shorthand (analogous to std/):

use "co/systems/company-repo-checker"

Which expands to github.com/openprose/prose/packages/co/systems/company-repo-checker.

Package Shape

Authored Prose source files use *.prose.md. README.md remains plain Markdown.

packages/co/
  README.md
  systems/
    company-repo-checker/
      index.prose.md
  services/
    agent-readiness.prose.md
  evals/
    agent-readiness.eval.prose.md
    company-repo-checker.eval.prose.md

Services and Systems

agent-readiness — narrow intake a founder can run in under a minute: scores how accessible their site is to AI agents (well-known paths, plain-HTML parseability, structured metadata) and writes a screenshot-ready markdown report to the run's bindings/agent-readiness.md. Safe first-run demo: three prompts, one WebFetch batch, one report binding.
company-repo-checker — static gate that verifies a company-as-prose repository still matches the shared layout before expensive runtime tests or fleet monitors do more work.

Future additions should help a new company get started without copying OpenProse, Inc.'s private business logic:

starter repository architecture
company system map
customer package checker
test ladder
fixture and run-replay conventions
onboarding system for the first operating responsibilities

std vs co — the split

std — use-case-agnostic primitives. Inspector, contract-grader, retry, fan-out, worker-critic, human-gate. Things that make Prose services and systems work.
co — company-operations-shaped patterns. Starter repo checkers, scheduled intake, windowed analytics, GTM pipelines, fleet monitors. Things that make Prose services and systems produce business value.

Running Services and Systems

prose run is an agent-session command. It is not assumed to be a shell binary. If a host provides a native Prose CLI, use it. Otherwise wrap the command in an agent runner that has the OpenProse skill loaded.

Claude Code:

claude -p "prose run co/systems/company-repo-checker --repo_path <company-repo>"

Codex:

codex exec -C <workspace-root> "prose run co/systems/company-repo-checker --repo_path <company-repo>"

The shell executable is claude or codex. The prose run ... string is the instruction the agent session interprets as the OpenProse VM.

Design Notes

Keep this package generic. Do not include OpenProse, Inc. leads, accounts, GTM logic, release logic, or private operating assumptions.
Prefer composable services and systems with inline starter services until a service earns a stable public API.
Put universal primitives in std/; put company-operating-system patterns here.
Keep generated runtime state out of this package. Useful lessons can become docs, fixtures, or tests.
