Every entry follows the canonical 7-axis shape in `TEMPLATE.md` (shipped alongside this skill). Every factual claim cites a primary source fetched in this session. ## Arguments `$ARGUMENTS` - **`<system-name>`** — 1 to 5 external system names (e.g. `Smithy Buf SPIFFE`). More than 5 → refuse. - **`--baseline=PATH`** *(default: `docs/prior-art/_baseline.md`)* — the "us" document the new entries compare against. - **`--output-dir=PATH`** *(default: `docs/prior-art/`)* — where new entries and the aggregator README live. - **`--decision=adopt|borrow`** *(default: `borrow`)* — what question the comparison serves. `adopt` surfaces wholesale-migration analysis; `borrow` surfaces pattern-extraction. ## What this skill solves Most "we should look at how X does this" research drifts into a write-up about X without ever rendering a comparison against what we already have. This skill enforces: 1. **One fixed shape** (the 7-axis template) — every entry is diffable. 2. **Citations not folklore** — every factual claim links to a URL fetched in this session. 3. **Decision-oriented output** — Adopt / Borrow / Skip with concrete next steps, not vibes. 4. **A single consumable matrix** — `README.md` in the output dir aggregates the verdicts. ## The 7 axes (defined in `TEMPLATE.md`) 1. **I
