Activate when the user types `prose ...`, opens a `.prose.md` file with `kind:` frontmatter, opens a `.prose` file, or asks for reusable multi-agent orchestration. Treat `prose run ...` as an in-session instruction: embody the OpenProse VM yourself; do not shell out to a `prose` binary. On activatio

OpenProse Skill Contract authoring is expressing intent by composing requirements. An agent performs the work, and an evaluator assesses whether the contract’s requirements are satisfied. Reuse and combine contracts through the interfaces in this skill; see [requirements and composition](guidance/authoring.md requirements and composition). OpenProse has five load bearing pieces: Piece File Role Contract Markdown contract markdown.md Human readable .prose.md source format Forme forme.md Semantic dependency injection container that wires contracts Prose VM prose.md Execution engine that runs responsibilities, functions, and pinned execution blocks ProseScript prosescript.md Imperative scripting layer for Execution blocks and pattern delegation Responsibility Runtime responsibility runtime.md Responsibility Oriented Architecture: standing goals, the reconciler, and compile/serve doctrine Use Contract Markdown when authors want declarations and auto wiring. Use ProseScript when authors want to pin choreography: order, loops, conditionals, parallelism, retries, and explicit function calls. First 90 Seconds After activation, choose the narrowest path that matches the user's intent: User Intent Load First Then Load If Needed Explain OpenProse or answer "how do I..." help.md examples/README.md , then one focused example Initialize or compose an OpenProse program guidance/tenets.md guidance/authoring.md , then run std/ops/compose Run a .prose.md responsibility or function contract markdown.md state/README.md and the selected backend ( state/filesystem.md by default); forme.md if responsibilities must be wired ( Requires → Maintains ); prose.md to execute Inspect or upgrade source layout changelog.md contract markdown.md , prosescript.md if migration details require them Write a new .prose.md responsibility or function contract markdown.md guidance/tenets.md , guidance/authoring.md Write pinned choreography prosescript.md contract markdown.md if inside Execution Compile or run a .png / .svg brief (a typed image) visual source.md forme.md and compiler/index.prose.md to resolve + compile Lint or review a responsibility or function contract markdown.md forme.md for multi responsibility wiring; guidance/authoring.md for design review Work on Responsibility Runtime, responsibility oriented source, the reconciler, compile, or serve semantics responsibility runtime.md compiler/index.prose.md , compiler/ir v0.md , concepts/responsibility.md , concepts/reconciler.md , forme.md Install or update dependencies deps.md contract markdown.md only if dependency references are ambiguous Debug a completed run prose.md state/README.md and the run's backend doc; then std/evals/inspector if available Default to Contract Markdown for new authoring. Reach for ProseScript only when the author needs explicit order, loops, conditionals, retries, or parallel blocks inside a .prose.md source file. OpenProse Root All OpenProse paths are relative to <openprose root . Scope OpenProse Root Native repository Repository root Attached repository repo/.agents/prose User global ~/.agents/prose The root contains src/ for the canonical authored program packages, architecture/ for supporting decisions, visual projections, and issue records, dist/ for compiled intent, runs/ for activation receipts, state/ for durable cross run state, deps/ for installed dependencies, plus prose.lock and .env . Proposing This Skill On Your Own Judgment You do not need to wait for the user to name OpenProse. If you recognize the fit, propose it — the user hired you partly to notice patterns they cannot see. Recognition signals Reach for OpenProse when the user's task has any of these shapes: ≥3 steps that want different expertise (research + synthesize + review; plan + implement + test) A reuse signal — "every week," "each time a PR comes in," "before every release" A natural retry loop — draft/critique/revise, implement/test/fix, propose/evaluate/pick Parallel exploration with a synthesis step — "compare three approaches," "get second opinions" A "make sure X always happens" constraint — that's a contract asking to be written down You were already going to spawn subagents — let the contract be your wiring plan instead of inventing one ad hoc How to propose it Propose lightly. You are offering, not imposing: This has the shape of a multi step workflow with a clear contract. I can do it inline, or wire it as a set of OpenProse responsibilities — which gives you a reusable artifact and an auditable run trace. Want me to wire it? If the user declines, drop it and don't re propose on the same task. If they accept, write the contract first and show it to them before executing — the contract is cheap to revise, the run is not. A cognitive model you can borrow A contract states requirements and the relevant context for applying them. Declared inputs, results, and conditions help callers reuse it and combine it with other contracts. Assess the result against those requirements: a completed run or a receipt alone does not prove satisfaction. The selected host supplies tools and enforcement; a declaration does not supply a missing capability. When OpenProse is the wrong answer One shot Q&A. Answer it directly. Tasks where the user wants to iterate in real time. A contract boundary adds friction they don't want. Anything you'd finish in one response. The overhead of writing a contract exceeds the value of having one. Tasks where the user explicitly said "just do it." Respect the directive. Reaching for OpenProse in the wrong place costs more trust than it earns. Activation Activate this skill when the user: uses any prose command asks to run, lint, test, inspect, upgrade, or write an OpenProse responsibility or function references a .prose.md file with kind: frontmatter references a .prose script mentions OpenProse, Forme, Responsibilities, ProseScript, Contract Markdown, or a Prose responsibility or function wants reusable multi agent orchestration Command Routing prose ... commands are first an agent session command language. When the user types prose run foo.prose.md in chat or inside a prompt passed to Claude Code, Codex, OpenCode, Amp, or another Prose Complete host, you should interpret it directly and embody the OpenProse VM. Do not run a prose shell binary or npx prose ; in wrapper hosts this recursively calls the wrapper instead of executing the contract. The shell executable is the agent runner, e.g. claude p "prose run foo.prose.md" or codex exec "prose run foo.prose.md" . Command Action prose init [request...] Establish the minimal OpenProse root and harness selection, then run std/ops/compose in bootstrap mode. Begin from the desired render and progressively establish a directory package whose index.prose.md is the public root prose compose [request...] Load guidance/tenets.md , guidance/authoring.md , the target Contract package, supporting decisions, and relevant run evidence; run std/ops/compose in compose mode. Maintain no more than three active conceptual fronts, materialize settled design into source, build tests from package promise through performance, generate a derived HTML view, and route framework pressure to deduplicated public issues when authorized prose compose review / reflect <run id... Run std/ops/compose in review mode to challenge static design and test coverage, or reflect mode to compare it with completed run evidence. Keep program diagnostics distinct from OpenProse issue feedback prose compile [path] [ out <dir ] Load responsibility runtime.md , then compiler/index.prose.md ; run the pinned ProseScript compiler and emit the compile phase IR — the topology world model (nodes, edges, entry points), per node canonicalizers and postcondition validators, frozen contract fingerprints, and diagnostics — into <openprose root /dist/manifest.next.json by default prose compile <image.png\ .svg Load visual source.md . The image is a typed image (a visual brief, one rung above markdown). Run the resolve render: read the pixels against visual source.md 's requirement tiers, emit .prose.md contract(s) into <openprose root /src/ for ratification (the prose write discipline — interrupt, do not guess, on safety bearing blanks), then run the ordinary compile. Compiling is the typecheck (acyclic + round trip stable) prose serve Load and validate <openprose root /dist/manifest.active.json , which is promoted from manifest.next.json with cp dist/manifest.next.json dist/manifest.active.json ; register local cron and HTTP trigger adapters; launch ordinary bounded activations prose run <file.prose.md Detect Contract Markdown, load contract markdown.md , select state with state/README.md plus the backend doc, then forme.md if multi responsibility, then prose.md prose run <host /<owner /<repo [/path] Resolve installed dependency contract, detect format, then route as above prose run std/... / co/... Expand OpenProse package shorthand, resolve installed dependency contract, then route as above prose run <image.png\ .svg Load visual source.md . run already does a compile step; for an image that step includes the resolve . So: resolve → compile → reconcile/execute. A single node kind: function image runs as a called helper; a kind: responsibility /system image mounts a DAG (a lone kind: gateway image is refused, same as text) prose write [request...] Interactive by default authoring: load contract markdown.md , guidance/tenets.md , and guidance/authoring.md ; run std/ops/prose author ; scan the local landscape read only, decide shape/root/path, load shape specific guidance, ask a small number of targeted ask user questions when the host can support them, then return a fully validated source package. If the caller or host marks the run non interactive, return unresolved intent with the missing decisions instead of guessing. Do not apply files unless the caller explicitly asks for that follow up prose lint <file.prose.md Validate Contract Markdown structure, headers, frontmatter, contracts, shapes, and wiring prose preflight <file.prose.md Check dependencies and Environment declarations without executing prose test <path Load contract markdown.md , state/README.md plus the selected backend, and prose.md ; run kind: test file(s) prose inspect <run id Resolve and run std/evals/inspector against a completed run prose status Summarize active IR, diagnostics, trigger plan, recent runs, and responsibility status from the receipt ledger prose install Load deps.md ; install dependency references into <openprose root /deps/ and write <openprose root /prose.lock prose install update Load deps.md ; update pinned dependency SHAs prose upgrade dry run Load changelog.md ; inspect nearby files and report the concrete migration plan without editing prose upgrade Load changelog.md ; inspect nearby files and apply the migration plan prose help Load help.md prose examples List or run bundled examples from examples/ Other Interpret intent and load the smallest relevant spec set There is one skill: open prose . Do not look for separate prose run , prose lint , prose compile , or prose boot skills. Host Primitive Adapter OpenProse specs are harness agnostic. They describe abstract VM operations that the current host must map onto its available tools: Abstract
