upgrade

description

Upgrades installed aos capabilities by folding the user's uncaptured hand-edits into their MOD.md and re-applying it to fresh upstream, diff-gated, one reviewable commit per render. Use when the user says "update" or "upgrade" — the whole kit or one capability — or after a git pull of the aos upstream clone. Do NOT use for a capability that is not installed yet (that is capability-install) or to change what a capability does for this user (capability-evolve); this skill preserves existing personalization rather than adding any.

capability-upgrade

Not in context yet? Load the capability-lifecycle skill first — the map, the contract, the overlay doctrine, and the Experience rules. The model: MOD.md states the user's deltas; upgrade = re-apply them to fresh upstream, into personal/'s working tree. The current install is a drift source, never a merge input; the review gate is a git diff in the user's own repo.

1. Scope: the named capability, else every entry in aos-cap list.
2. Kit-wide: pull <home>/upstream from the canonical remote (git pull upstream main when an upstream remote exists, else git pull) — it cannot touch personal/, a different repo. On a non-main branch (a contributor dogfooding a change, or a self-drafted cheat-sheet branch): skip the pull, say so, name the branch, and say how to resume upstream updates (git -C <home>/upstream switch main). A capability needs work when its manifest version (aos-cap manifest) ≠ its lockfile version. Migration note: overlay files found inside the clone (a pre-household install) → offer the one-time move into personal/ before anything else. Referenced third-party skills come along: for each recorded link into <home>/vendor, git -C <vendor-clone> pull --ff-only (or the harness's plugin update), then re-record so the hashes match. Offline or a dirty clone → say so and continue; a stale reference is never a blocker.
3. Per capability needing work: a. aos-cap verify <id> — two classes, two responses. Artifact drift (a render file's hash changed = the user's hand-edit) → fold each into MOD.md first per the capability-lifecycle skill's reference/overlay.md (edit the statement that covers it — never append a contradicting one) ("you changed X — keeping it"). Link damage (MISSING LINK, NOT A LINK (copies are banned), RELINKED, DANGLING LINK) is not a hand-edit and never folds: re-create the link from the lockfile's recorded target, say what you repaired, and stop if the target itself is gone (that is a broken install, not an upgrade). A fold that reaches beyond the {{mod}} slots is mechanism-shaped — note it for the promotion judgment (overlay.md, Promote and retire), end of conversation. b. Name gate: aos-cap --home <home> skills <dir> --check --harness-skills <each skills dir this harness reads>. Upstream may have renamed or added a skill, so the installed names can differ from the recorded links — a rename means link the new name and drop the old one in step d. Exit 17 → stop and report; never rename locally. This capability's own links are exempt, so a plain re-render is always clean. If it ships agents/, gate those too in the same breath: aos-cap --home <home> agents <dir> --check — same flat namespace, same exit 17, same never-rename-locally. It checks two of three sources and names the third (agents already in the harness — no enumeration yet) in capitals. c. First, before --force touches anything: git -C <home>/personal status --porcelain -- capabilities/<id>. --force re-render is rmtree then copytree, so a pre-existing untracked file of the user's under that directory is gone with no commit to recover it from — and aos-cap verify cannot warn you, because it is add-blind (an extra file inside a recorded render reports clean). Name any ?? entry to the user and get a decision before proceeding; a tracked file is safe (the diff in step d shows it). Then re-render: aos-cap render <dir> <skill-id> --out <home>/personal/capabilities/<id>/skills --force per declared skill, then fresh upstream × MOD.md — the same transform as install (reference/overlay.md), written into personal/'s working tree; interview only new or re_ask questions. A skill whose installed name changed leaves its old render directory behind: delete it in the same commit, so the diff shows the rename as one move. Then STAGE any native-plan changes per the cheat-sheet (load it now if not in context). d. GATE: stage this capability, then diff it — then — the old render vs the new, per file, (a bare hides them) — plus the native plan. Approve → commit (dated message). Decline → , then as belt-and-braces (restore already removes the staged additions; clean catches anything staging missed), stop. Keep every command path-scoped: unscoped staging or resetting would capture — or destroy — unrelated work elsewhere in . (The untracked-file check is step c's, because by this point has already run — a warning here would name a file that no longer exists.) e. , before recording: . Nothing else in this flow updates a binary, and will otherwise serve whatever it has cached — so an upgrade that re-renders every skill can leave the executable those skills call several versions behind, with the prose describing behaviour the binary does not have. is what makes it re-resolve; the version in the tool's tracks the capability's, so a bumped capability is a bumped package. f. EXECUTE the native plan (links usually survive re-render untouched — verify, don't assume); with the full updated set (start from — replaces the entry wholesale, never call it with a partial list; keep and records). g. Retirement pass (overlay.md, Promote and retire): fresh upstream now covers a MOD statement — a new interview question over its subject, or the behavior baked in → offer to retire it (diff-shown; written only through {{skill: evolve}}).
4. Absorbed capabilities. A lockfile entry whose capability no longer exists upstream was folded into another one (0.3.0 absorbed onboarding, importer, and capability-builder into capability-lifecycle). Say what happened, then: unlink that entry's skill links, aos-cap remove <absorbed-id>, and let the absorbing capability's own upgrade render the replacements. Retired context-block markers (aos:onboarding@…, aos:capability-builder@…) come out in the same pass — the mode-boundary block carries its own marker. A pre-0.3.0 install also has an identity block distilled from the global MOD: remove it, say why (the harness owns user context; MOD.md remains the authoritative store), and write nothing in its place. MOD.md files never move on their own: if the absorbing capability's interview covers the same questions, offer the merge; otherwise leave the file and say it is now unused.
5. Report per capability: upstream changes taken, MOD statements re-applied, statements retired, anything folded in step a, any skill renamed or capability absorbed — and at most one promotion offer, if a fold qualified.
