…+ Table C-2.2) Fills the one clear free-source gap in the public US AISC connection-detailing agent: how to size a high-strength bolt's LENGTH from the grip. Every other §J bolt rule (spacing/edge/holes/pretension/washers/bearing-tearout/block-shear) was already skilled; bolt length was not. New skill skills/bolt-length-and-grip.md, strictly free-source and cited the same way as the rest of the agent (rule -> condition -> source + verbatim quote, refuse-when-unsourced): - Grip = total thickness of the connected plies, excl. washers/DTIs (RCSC 2020 Glossary). - Normative length requirement: length shall achieve sufficient thread engagement (RCSC 2020 §2.7 + Glossary "Sufficient Thread Engagement"). - Selection method: length = grip + add-to-grip value, rounded to 1/4 in. (1/2 in. over 6 in.); +5/32 in. per flat washer, +5/16 in. per beveled washer (RCSC 2020 Commentary §2.7, Table C-2.2). - The more extensive add-to-grip TABLE = AISC Manual Table 7-18 (Carter 1996) — paid; cited by reference only, never reproduced (matches the agent's scope-and-citation copyright posture). All quotes verified against the genuine RCSC 2020 PDF (boltcouncil.org). Also adds 4 matching lookup rules to rules/aisc-360-22.json (66 -> 70) and lists the skill in manifest.yaml; agent version 0.2.0 -> 0.3.0. `aware agent validate` passes; skill installs, indexes, and renders.
…+ Carter 1996, drop unverifiable Manual table no. Addresses the dual review (Codex). The first cut equated RCSC's "more extensive table (Carter, 1996)" with "AISC Manual Table 7-18" — but that equivalence is not provable from any free source, and a check found the Manual's bolt-length table was historically Table 7-2 (older editions, since removed), not 7-18. For an agent whose whole value is verified-from-free-source citations, asserting an unverifiable paid-table number is a scope violation. Reworded (skill + the bolt.length.select JSON citation) to cite only what is free + verifiable: the per-diameter values live in RCSC 2020 Table C-2.2 (free, in the Commentary), and RCSC's own cited "more extensive" reference is Carter, C.J., "Specifying Bolt Length for High-Strength Bolts," AISC Engineering Journal, Vol. 33 No. 2 (2nd Qtr. 1996) — free. The AISC Manual is named only generically (paid; reference-only; no specific table number). Also: bolt.length.engagement units "—" -> "dimensionless" to match the DB's existing convention (pr-review-toolkit nit). The beveled-washer +5/16 in. value was confirmed from the RENDERED RCSC PDF page (the PDF's fraction-font glyphs garble in plain text extraction but render correctly).

…ships #273) PR #273 added skills/bolt-length-and-grip.md to steel-detailer-us and bumped its manifest to 0.3.0, but did not regenerate registry-catalog.json. The CLI serves the catalog + agent tarballs from main (raw.githubusercontent .../main/ registry-catalog.json and archive/refs/heads/main.tar.gz), so the stale catalog omitted the new skill and still showed manifest-version 0.2.0 — `aware agent reindex --check` flagged it. Regenerated via `aware agent reindex`: adds bolt-length-and-grip to the steel-detailer-us skill list, updates manifest-version 0.2.0->0.3.0, and bumps updated-at to bust client tarball caches. This is the ship step for a registry-distributed knowledge agent — no @aware-aeco/cli release: the CLI binary is unchanged and agents are served from main, not from a release tag.
