# PM - Feature Design (JIT) ## Agent mode (`--agent`) Supports `--agent`: runs autonomously in a subagent, drafts the artifact from existing inputs, and returns a short summary + coverage note. - **No flag** → interactive (default); if inputs are heavy, offer agent mode. - **`--agent`** → obey. First check inputs are complete. Anything missing: do NOT invent it - mark `[ASSUMED - what/why]` in the output and summary. Never hallucinate to fill a gap. - **Review required:** the artifact contains commitments - after drafting, require the user's review before finalizing; do not close decisions autonomously. --- ## Standalone run Needs the artifacts listed under **Dependencies** - it synthesizes them, so without them there is nothing to synthesize. - No workspace, or inputs missing: name which are missing and what each one unlocks, then offer the PREREQ paths - proceed on stated assumptions marked `[ASSUMED - what/why]`, or route to the skill that produces the missing input. Never hard-block, and never invent the input. - Writing never depends on `/pureinn` having run: with no workspace, create just the folder this skill writes into, or write to a path the user names, and say where the file went. - Read `pureinn-variables.md` / `state.json` where a value is actually used, not at the top of the run. Missing value: continue and name the capability it costs. --- ## What this skill does Produces the Just-In-Time technical design for a single feature immediately before it ente
