After a plugin update, abcd offers to bring the repository's setup up to date

Press Release

After a plugin update, abcd offers to bring the repository's setup up to date. When the abcd plugin has been updated since a repository was last set up and the update brings something the repository needs, the agent's first reply in the next session says so and offers to run setup again, so new settings and new setup questions reach the repository instead of waiting until someone happens to run setup. Alice, a solo founder, updates the plugin in the evening; the next morning the first reply to their first message says: abcd was updated to 0.16.0, two setup questions are waiting here, run setup now? They answer yes, setup asks only the new questions, and their repository picks up the new settings. Nothing changes without that yes, and noticing the update reads only what is on disk, never the internet.

Why This Matters

Proposed by the agent on 2026-10-16 from the code and the ledger, unconfirmed: the planning interview confirms or rewrites it.

Setup (ahoy install) is the only step that brings a repository up to what the installed abcd can do: the settings a new release writes, the questions it adds, and the records it reshapes. The plugin updates on the host's schedule, one machine at a time; a repository's setup moves only when someone runs setup, and nothing tells them to. Release 0.15.0 is the example: --outbound-hook and --outbound-forge became --outbound, and a repository that recorded only one half "is reported, and the next ahoy install completes it". A repository whose people never re-run setup never gets that completion. The README question (itd-2610031348087517) reached existing repositories the same way: only when someone happened to run setup again.

The fact is already on disk. ahoy install stamps meta.setup_version into .abcd/config.json, and the bare abcd ahoy reports a version.upgrade gap when the running abcd differs from it. But that gap is seen only by someone who thinks to run abcd ahoy. Session start compared the two once and stopped (iss-2609291942520919, dcn-2609300000000011): that ruling moved the "abcd updated from X to Y" line to whatever performed the swap, once per machine. It did not decide whether each repository's setup has caught up, which is the question this intent asks.

Mechanism

Proposed by the agent on 2026-10-16, unconfirmed.

We expect a repository to pick up a release's new settings and questions within one session of the update, because the offer arrives when the person is already starting work in that repository, names what is waiting (how many new questions), and costs one yes. Today the same fact sits behind a verb nobody runs without a reason, so a repository's setup lags until something breaks.

Scope Conditions

Proposed by the agent on 2026-10-16, unconfirmed.

• The repository has been set up by ahoy install at least once, so .abcd/config.json records a release setup_version; a repository abcd does not manage gets no offer, because adopting it is ahoy's own path.
• Both the recorded setup version and the running binary are release versions; a dev build on either side takes no part, the rule version.upgrade already keeps (iss-2608241115259170).
• The host runs abcd's session-start hook and its agent can put a question to the person; a host without hooks learns of the waiting setup only from abcd ahoy.
• The update has reached the running binary: the binary's own version is the "updated to" side, not a plugin root whose binary has not been swapped yet.

Acceptance Criteria

Seeded by the agent on 2026-10-16 from the code and the two drafts, unconfirmed: the planning interview walks each one.

• Given Alice, a solo founder, whose repository was set up with 0.15.0 and whose plugin now runs 0.16.0 and adds a setup question they have never answered, when they send the first message of their next session in that repository, then the agent's first reply offers to run setup again in one line, naming the version the repository was set up with, the version now running, and how many questions and changed defaults wait, with their titles on request; nothing is written to the repository before they answer.
• Given an update that brings this repository nothing it needs (no question it has never answered and no setting whose default changed), when the next session starts, then no offer appears, and abcd ahoy stays the place to check.
• Given Alice answers yes, when setup runs, then it asks only the questions this repository has never answered and the settings whose default changed in the update, never re-asks a question answered with a value or deferred with "decide later", and records the new setup version when it completes.
• Given Alice answers "not now", when later sessions start in that repository before the next update, then the offer is not repeated, and abcd ahoy still lists the waiting setup with the command that runs it.
• Given Alice answers the offer either way, when the answer is recorded, then the abcd verb the agent runs with her answer records it, keyed on the repository and the release, in abcd's own data directory; the session-start hook writes nothing for it.
• Given Alice declined the offer for 0.16.0, when the plugin moves on to 0.16.1, then the next session in that repository offers once more.
• Given a session with no person to answer it (a headless or scripted run), when the session starts, then setup is not run and nothing is written; the waiting setup is reported as a notice only, and an ahoy install --yes run never counts as the person's yes to a new value question.
• Given Bob, a staff engineer, whose repository's setup version matches the running abcd, or where either side is a dev build, when a session starts, then no offer appears.
• Given Carol, a tech lead, whose teammate has already re-run setup and committed a setup version equal to or newer than Carol's plugin, when Carol's session starts, then no offer appears, and setup is never offered as a way to record an older version.
• Given any session start, when the offer is worked out, then nothing is fetched from the network (the versions come from the running binary and the repository's .abcd/config.json), and no word from the repository's tracked files reaches the session's context unchecked: the recorded setup version is checked to be exactly a release tag of the form vX.Y.Z (digits only) before it reaches the session's context, and any other value is left off that channel.

Decisions

The product thinker answered four of these on 2026-10-16; the agent decided the rest on 2026-10-17 during an autonomous run, on the grounds given.

• How often: once per update per repository; after that only abcd ahoy lists it (product thinker).
• Where it appears: asked in the agent's first reply, after the person's first message, so a session opened for something urgent is not interrupted before it starts (product thinker).
• Which questions count: every question this repository has never answered, leaving out those deferred with "decide later", plus every setting whose default changed in the update (product thinker).
• An update with nothing needed: offered only when something is required; an update that brings no such question or setting offers nothing (product thinker).
• Where the answer is remembered: in abcd's data directory, keyed on the repository's root commit and the release, and written by the verb the agent runs with the answer, never by the session-start hook, so the hook's single write exception (dcn-2609300000000011) stays single (agent, from the design review).
• One sentence or the list: one line with the count, the titles on request, matching the summary's one-line form (agent).
• Bundle shape with itd-2610161617096084: one moment in the first reply: the one-line summary of what changed, then the offer (agent).

Acceptance rollup: MET 7 · MET_WITH_CONCERNS 3 · NOT_MET 0 · INCONCLUSIVE 0

Per-criterion verdicts:

• ac-1 — MET_WITH_CONCERNS: The offer line names the setup version, the running release and the counts, --full lists the titles, and bare update news writes nothing. Concerns: the first-reply relay is agent behaviour, steered only by a constant hook line and the command page, and its live-run proof sits in a session scratchpad outside the tree (the first run restated the lines instead of relaying them). The default-change table also ships empty, so no shipped binary ever counts a changed default. evidence: internal/core/afterupdate/afterupdate.go:541 — "return "abcd was updated from " + from + " to " + to + " since this repository was set up; " +" evidence: internal/core/afterupdate/afterupdate.go:589 — "out = append(out, "Waiting in this repository:")" evidence: internal/surface/cli/update_news_test.go:116 — "if after := pathsUnder(t, home) + pathsUnder(t, repo); after != before {" evidence: internal/core/ahoy/defaults/default-changes.json:3 — ""changes": []" evidence: .abcd/development/specs/closed/spc-2610170635097509-after-update.md:689 — "opened its first reply with the news and the offer (restated, not verbatim)"

• ac-3 — MET_WITH_CONCERNS: The --only-waiting prompter puts only Waiting's keys and skips any question with a recorded answer (a value or later); a test holds that only waiting keys are put and setup_version becomes the running release. Concerns: (1) answers are read from the checkout's local-tier records, so a fresh clone or another worktree asks again a question deferred with 'decide later'; (2) stepVersionStamp runs before stepArtefact and on an --only-waiting --yes run that answers nothing, so the new version is recorded before setup completes, not only when it completes. evidence: internal/core/ahoy/only_waiting.go:101 — "if !w.filter.asks(key) {" evidence: internal/core/ahoy/waiting.go:87 — "if _, recorded := answers[q.Key]; recorded {" evidence: internal/core/ahoy/only_waiting_test.go:99 — "if got := readConfigT(t, repo)["meta"].(map[string]any)["setup_version"]; got != "v0.16.0" {" evidence: internal/core/interview/interview.go:91 — "const RecordsRel = ".abcd/.work.local/interviews"" evidence: internal/core/ahoy/apply.go:299 — "ac.stepVersionStamp()" evidence: .abcd/development/specs/closed/spc-2610170635097509-after-update.md:383 — "the existing rule, so such a run records the running release and the"

• ac-7 — MET_WITH_CONCERNS: The hook writes nothing and runs no setup, and an --only-waiting --yes run puts no question and leaves every waiting value unset (tested). Concerns: (1) a plain ahoy install --yes still settles the artefact kind and the house-style question by default without asking, so the guarantee holds only with --only-waiting; (2) an --only-waiting --yes run that answers nothing still stamps the running release, which ends the offer for that release; (3) 'nothing written' in a headless run depends on the command page telling the agent not to run --answer or --seen, because the binary cannot tell. evidence: internal/surface/cli/hook_session_start_update_news_test.go:47 — "if after := pathsUnder(t, repo); after != before {" evidence: internal/core/ahoy/only_waiting.go:37 — "f := &waitingFilter{keys: map[string]bool{}, none: opts.Yes}" evidence: internal/core/ahoy/only_waiting_test.go:125 — "if len(p.keys) != 0 {" evidence: internal/core/ahoy/artefact.go:124 — "the artefact kind was not asked (an unattended --yes install):" evidence: internal/core/ahoy/docslint_seed.go:63 — "if a.autoYes {" evidence: commands/update.md:235 — "run neither --answer nor --seen: the binary cannot tell such a run from a"

Grounds

• pursued: we expect a repository to pick up a release's new questions and changed defaults within one session of the update, because the offer arrives in the first reply and costs one yes; repositories still on an old setup version a week after an update would show it wrong
