The install→restart→wire "phases" aren't a driver concern; they're directives in document order. Restart is a run, placed between the install/credentials and the wiring, and the engine already runs directives top-to-bottom — so no phase orchestration is needed. - effect:restart: a run whose body restarts the service and waits for the ncl socket so a following wiring directive doesn't race it. New helper setup/lib/restart.sh (platform-aware restart + best-effort socket wait; the engine execs each body line separately, so one self-contained script). - ApplyOptions.skipEffects: run effects the CALLER owns and performs itself are skipped (not executed). A standalone /add-slack runs the restart; a headless rebuild or a setup that restarts once at the end passes ['restart'] and it's skipped. The declarative form of applyProviderSkill's isFlowOwnedCommand. add-slack now carries the restart between Credentials and the wire, so the whole flow is one self-contained ordered directive sequence. Dry-run: standalone runs the restart, a flow caller skips it — both fully apply, both wire. 604 pass. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>

// Extract `nc:` skill directives embedded in a SKILL.md.
|
|
//
|
|
// A fenced code block whose info-string starts with `nc:` is a load-bearing
|
|
// directive; every other fence (and all prose) is the human floor the parser
|
|
// ignores. That is the whole "two readers, one document" property: an agent
|
|
// applies the prose, a tool applies the directives, and anything the tool
|
|
// can't handle degrades to the prose beside it. This is the seed for both the
|
|
// conformance linter and the deterministic applier.
|
|
//
|
|
// Grammar, derived from add-slack:
|
|
//
|
|
// ```nc:<directive> <arg>... [key:value]...
|
|
// <body line>
|
|
// ```
|
|
//
|
|
// `prompt` only *acquires* a value and binds it to a name; a separate directive
|
|
// *applies* it, referenced as `{{name}}`. That keeps "ask the human" decoupled
|
|
// from "what you do with the answer" (env, ncl, the OneCLI vault, a file).
|
|
//
|
|
// copy [from-branch:<b>] body: `PATH` (src==dst) or `SRC -> DST` overwrite
|
|
// append to:<file> [at:<marker>] body: line(s) to add skip if present
|
|
// dep [manager:pnpm] body: `pkg@<exact-semver>` line(s) reinstall no-op
|
|
// run [effect:build|test|fetch|external|wire|restart] [capture:<var>] re-runnable
|
|
// body: shell command(s). {{vars}} are substituted in. effect:wire runs
|
|
// `ncl …` to wire collected input (no undo — the rows it creates are user
|
|
// runtime data, not reversed on skill remove). effect:restart restarts the
|
|
// service so following `ncl` runs reach it; a caller that owns the restart
|
|
// (rebuild, or a setup that restarts once) skips it via ApplyOptions.
|
|
// skipEffects. capture:<var> binds the command's stdout into {{var}} (twin
|
|
// of prompt) — e.g. resolve an id from an API and feed it to a later step.
|
|
// prompt <var> [secret] body: the question → binds {{var}} skip if satisfied
|
|
// operator body: instructions for the human operator output-only
|
|
// The SKILL.md is addressed to the coding agent; `operator` delineates the
|
|
// parts meant for the HUMAN (e.g. clicking through the Slack UI). Lead it
|
|
// with agent-facing prose like "Tell the user:" so the agent relays it;
|
|
// the engine renders the body to the operator ({{vars}} substituted in).
|
|
// env-set body: `KEY=value` ({{var}} allowed) set-if-absent
|
|
// env-sync (no body) `.env` → data/env/env idempotent copy
|
|
// json-merge into:<file> key:<field> body: a JSON object push-if-absent
|
|
//
|
|
// `append` without `at:` adds to EOF; with `at:<marker>` it inserts before the
|
|
// `// <<< <marker>` closing line of a dormant marker region (see setup/index.ts).
|
|
// `json-merge` reads an array-of-objects JSON file and pushes the body object
|
|
// unless an element already has body[key]===element[key] (idempotent by key).
|
|
//
|
|
// Usage: pnpm exec tsx scripts/skill-directives.ts <SKILL.md>
