feat(plugin): #544 SessionStart update-available reminder for plugin installs
Closes #544 (follow-up to #543). New scripts/ars_update_check.sh + SessionStart announce integration: plugin installs behind main get a one-line session-start reminder pointing at /plugin update academic-research-skills. 24h cache, 3s network ceiling, ARS_UPDATE_CHECK=0 kill switch, every failure path silent, announce byte-identical when current / disabled / not a plugin install. Security: the version value that flows into SessionStart additionalContext is validated by an allow-known grammar (bounded numeric core + at most one recognized release marker, 32-char cap) at every entry point (remote, local, both cache fields) before it is cached or emitted, closing a prompt-injection / JSON-envelope-corruption path. Converged to 0 P1/P2 across three rounds of parallel codex (gpt-5.6-sol xhigh) + security-review + adversarial checks. 37-test hermetic suite (manifest id 544-update-reminder); SETUP en/zh-TW + CHANGELOG updated. Spec: docs/design/2026-07-18-544-update-reminder-spec.md. 🤖 Generated with [Claude Code](https://claude.com/claude-code)

- **SessionStart update-available reminder for plugin installs (#543 → #544).** New `scripts/ars_update_check.sh` (Bash 3.2, no jq, always-exit-0 fail-silent) compares the installed plugin version against `main`'s `.claude-plugin/plugin.json` — 24 h cache at `~/.cache/ars/update-check`, 3 s network ceiling, `ARS_UPDATE_CHECK=0` kill switch — and the SessionStart announce prepends a one-line reminder pointing at `/plugin update academic-research-skills` when behind. Motivated by #543 (reporter six minor versions behind on a long-fixed bug): third-party marketplaces default auto-update OFF and surface no behind-signal. Hermetic 15-test suite (`scripts/test_ars_update_check.py`, manifest id `544-update-reminder`). Spec: `docs/design/2026-07-18-544-update-reminder-spec.md`.

**Built-in update reminder.** The plugin also nudges you on its own: at session start it compares your installed version against `main` (at most one network request per day, 3-second ceiling, silent on any failure) and, when you are behind, prepends one line to the session-start announce pointing at `/plugin update academic-research-skills`. Set `ARS_UPDATE_CHECK=0` to disable the check entirely. Privacy: the check performs a single HTTPS GET of this repository's public `.claude-plugin/plugin.json` and transmits no user data.

# #544 — SessionStart update-available reminder for plugin installs
|
||||
|
||||
**Status:** spec for the feature branch `feat/544-update-reminder`
|
||||
**Affects:** `scripts/announce-ars-loaded.sh` (SessionStart announce), new `scripts/ars_update_check.sh`, new `scripts/test_ars_update_check.py`, `docs/SETUP.md` (+ zh-TW twin), CHANGELOG.
|
||||
**Eval impact:** none (no scoring / generation / gold-set change).
|
||||
|
||||
## Problem
|
||||
|
||||
Issue #543's reporter hit a bug on suite v3.11.1 that had been fixed since v3.12.2 /
|
||||
v3.13.0 (#449 / #459) — six minor versions behind at report time. This is a recurring
|
||||
class, not a one-off, because of two platform facts (first-party verified against
|
||||
code.claude.com docs, 2026-07-18):
|
||||
|
||||
1. Third-party marketplaces have auto-update **disabled by default**. Only a manual
|
||||
`/plugin update` or an explicit per-marketplace auto-update toggle pulls new
|
||||
versions. Official Anthropic marketplaces default ON; ours defaults OFF.
|
||||
2. Update detection compares the `version` string in `.claude-plugin/plugin.json`.
|
||||
A user who is behind sees no signal anywhere that they are behind.
|
||||
|
||||
ARS releases roughly every 1–2 weeks (`docs/SETUP.md` already says so and "strongly
|
||||
recommends" enabling auto-update — advice an installed-and-forgotten user never
|
||||
re-reads). A user who installed once and never toggled auto-update silently
|
||||
accumulates months of drift, then reports already-fixed bugs.
|
||||
|
||||
## Scope decision (settled with maintainer, 2026-07-18)
|
||||
|
||||
**Plugin installs only.** The reminder rides the existing SessionStart announce hook,
|
||||
which only exists under a plugin install (`hooks/hooks.json` + `CLAUDE_PLUGIN_ROOT`).
|
||||
Clone/symlink installs (SETUP Methods 1–3) are out of scope by design: those users
|
||||
update via `git pull`, chose a manual layout deliberately, and run no plugin hooks. A
|
||||
gstack-style per-SKILL.md preamble check (which would cover every install layout) was
|
||||
considered and rejected: it touches all four SKILL.md files, needs per-layout wording,
|
||||
and doubles the maintenance surface for the population least likely to be stuck.
|
||||
|
||||
## Design
|
||||
|
||||
### New script: `scripts/ars_update_check.sh`
|
||||
|
||||
A self-contained version checker. Called by the announce script; also runnable
|
||||
standalone. Same portability discipline as `announce-ars-loaded.sh`: Bash 3.2
|
||||
compatible, no jq, no Bash 4+ features.
|
||||
|
||||
**Output contract (stdout, single line or nothing):**
|
||||
|
||||
| Output | Meaning |
|
||||
|---|---|
|
||||
| `UPDATE_AVAILABLE <installed> <latest>` | remote version differs from installed |
|
||||
| *(nothing)* | up to date, disabled, not a plugin install, or any failure |
|
||||
|
||||
Exit code is always 0. The checker never prints to stderr on the happy path and the
|
||||
caller discards stderr regardless.
|
||||
|
||||
**Steps:**
|
||||
|
||||
1. **Kill switch.** `ARS_UPDATE_CHECK=0` → exit silently. Documented user-facing
|
||||
toggle. (Any other value, including unset, means enabled.)
|
||||
2. **Plugin gate.** `CLAUDE_PLUGIN_ROOT` unset or `${CLAUDE_PLUGIN_ROOT}/.claude-plugin/plugin.json`
|
||||
unreadable → exit silently. This is the mechanism that scopes the feature to
|
||||
plugin installs.
|
||||
3. **Local version.** First `"version": "<value>"` match in the local `plugin.json`,
|
||||
extracted with the same `[[ =~ ]]` regex style the announce script uses for
|
||||
`source`. Parse miss → exit silently.
|
||||
4. **Cache consult.** Cache file `${ARS_UPDATE_CHECK_STATE_DIR:-$HOME/.cache/ars}/update-check`,
|
||||
format `<STATE> <installed-at-check> <latest>` (STATE ∈ `UP_TO_DATE` /
|
||||
`UPDATE_AVAILABLE`). If the file exists, is well-formed, its mtime is younger than
|
||||
24 h, **and** its `<installed-at-check>` equals the current local version: render
|
||||
from cache (emit the token for `UPDATE_AVAILABLE`, emit nothing for `UP_TO_DATE`)
|
||||
and exit — no network. A recorded local version that differs from the current one
|
||||
means the user updated since the check; fall through to refetch. Malformed cache →
|
||||
fall through to refetch.
|
||||
5. **Remote fetch.** `curl -fsSL --max-time 3` on
|
||||
`${ARS_UPDATE_CHECK_REMOTE_URL:-https://raw.githubusercontent.com/Imbad0202/academic-research-skills/main/.claude-plugin/plugin.json}`,
|
||||
parse `version` with the same regex. curl missing, fetch failure, or parse miss →
|
||||
exit silently **without touching the cache** (a stale good cache beats a poisoned
|
||||
one; the next session retries).
|
||||
6. **Compare + write cache.** Plain string inequality (no semver ordering — the only
|
||||
question is "does `/plugin update` deliver something different"). Write the cache
|
||||
line atomically (temp file + `mv`), then emit the token if versions differ.
|
||||
|
||||
Remote choice rationale: `main`'s `plugin.json` is exactly what `/plugin update`
|
||||
delivers (the marketplace tracks the repo; the version string is the update key —
|
||||
see #459's release-gap postmortem), so comparing against `main` matches the
|
||||
platform's own update semantics. Release tags would drift from what an update
|
||||
actually installs during the merge→tag window.
|
||||
|
||||
**Env overrides** (testing + user control):
|
||||
|
||||
| Variable | Default | Role |
|
||||
|---|---|---|
|
||||
| `ARS_UPDATE_CHECK` | unset (enabled) | `0` disables everything |
|
||||
| `ARS_UPDATE_CHECK_STATE_DIR` | `~/.cache/ars` | cache directory (tests point it at a tmpdir) |
|
||||
| `ARS_UPDATE_CHECK_REMOTE_URL` | raw `main` plugin.json | remote source (tests use `file://` fixtures) |
|
||||
|
||||
Local version needs no override: tests set `CLAUDE_PLUGIN_ROOT` to a fixture
|
||||
directory.
|
||||
|
||||
### Announce integration: `scripts/announce-ars-loaded.sh`
|
||||
|
||||
Only the `startup|clear` branch changes (compact/resume stays minimal — no network,
|
||||
no reminder mid-session). The checker is invoked **inside the `startup|clear` case
|
||||
arm** — not before the `case` — so `compact`/`resume` never runs it, keeping the
|
||||
no-network promise for those paths structural rather than incidental:
|
||||
|
||||
```bash
|
||||
UPDATE_LINE=""
|
||||
if [[ -n "${CLAUDE_PLUGIN_ROOT:-}" ]]; then
|
||||
_UPD=$(bash "${CLAUDE_PLUGIN_ROOT}/scripts/ars_update_check.sh" 2>/dev/null || true)
|
||||
if [[ "${_UPD}" =~ ^UPDATE_AVAILABLE[[:space:]]([^[:space:]]+)[[:space:]]([^[:space:]]+)$ ]]; then
|
||||
UPDATE_LINE="ARS update available: v${BASH_REMATCH[2]} (installed: v${BASH_REMATCH[1]}). Run /plugin update academic-research-skills, or enable auto-update in /plugin -> Marketplaces.
|
||||
|
||||
"
|
||||
fi
|
||||
fi
|
||||
```
|
||||
|
||||
and the `startup|clear` case prepends `${UPDATE_LINE}` to the existing `ANNOUNCE`
|
||||
text. The reminder is one line of `additionalContext`; Claude relays it to the user
|
||||
at session start. It re-renders every new session until the user updates — no
|
||||
snooze/backoff ladder (that machinery exists in gstack for interactive upgrade
|
||||
prompts; one context line does not warrant it; revisit only on user noise reports).
|
||||
|
||||
The `|| true` + regex-gate means any checker misbehavior degrades to "no reminder",
|
||||
never a broken announce. The checker's token-only output contract keeps all
|
||||
human-facing wording in the announce script (single wording surface, and the ASCII
|
||||
`->` keeps the JSON-escaping path trivial).
|
||||
|
||||
### Error handling summary
|
||||
|
||||
| Failure | Behavior |
|
||||
|---|---|
|
||||
| `ARS_UPDATE_CHECK=0` | fully off — no network, no output |
|
||||
| not a plugin install | silent skip |
|
||||
| offline / timeout / GitHub down | silent skip, cache untouched, retry next session after TTL |
|
||||
| curl absent (unusual even on Windows Git Bash) | silent skip |
|
||||
| local or remote version parse miss | silent skip |
|
||||
| corrupt cache | ignored, refetched |
|
||||
| checker crashes entirely | announce unaffected (`|| true`) |
|
||||
|
||||
Privacy: the check fetches one public file from this repository over HTTPS and
|
||||
transmits no user data beyond that HTTP request. Stated in SETUP.md next to the
|
||||
kill switch.
|
||||
|
||||
### Tests: `scripts/test_ars_update_check.py`
|
||||
|
||||
Pytest, subprocess-driving the bash script — hermetic, no network: remote is a
|
||||
`file://` URL to fixture `plugin.json` files in a tmpdir, state dir is a tmpdir,
|
||||
`CLAUDE_PLUGIN_ROOT` is a fixture directory. TTL cases manipulate cache mtime via
|
||||
`os.utime`. Cases:
|
||||
|
||||
1. `ARS_UPDATE_CHECK=0` → no output, no cache write, no fetch.
|
||||
2. `CLAUDE_PLUGIN_ROOT` unset → no output.
|
||||
3. local == remote → no output; cache written `UP_TO_DATE`.
|
||||
4. local != remote → `UPDATE_AVAILABLE <local> <remote>`; cache written.
|
||||
5. Fresh `UPDATE_AVAILABLE` cache → token emitted with **no** fetch (proved by
|
||||
pointing the remote URL at a fixture with a third version and asserting the
|
||||
cached value is what renders).
|
||||
6. Fresh `UP_TO_DATE` cache → silent, no fetch (remote points at a newer fixture;
|
||||
still silent until TTL expiry).
|
||||
7. Expired cache (mtime > 24 h) → refetch, output and cache reflect the new remote.
|
||||
8. Expired cache + remote unreachable (`file://` to a nonexistent path) → silent;
|
||||
the stale cache file is left in place untouched (next session retries the fetch).
|
||||
9. Malformed remote JSON → silent, cache untouched.
|
||||
10. Corrupt cache → refetch succeeds, cache rewritten.
|
||||
11. User updated (current local == cached `<latest>`, cache fresh) → cache local
|
||||
mismatch forces refetch → now `UP_TO_DATE`, silent.
|
||||
12. Announce integration, behind: run `announce-ars-loaded.sh` with
|
||||
`{"source":"startup"}` on stdin and checker env pointing at fixtures → emitted
|
||||
`additionalContext` starts with the reminder line.
|
||||
13. Announce integration, current: same but versions equal → announce byte-identical
|
||||
to pre-change output.
|
||||
14. Announce integration, checker absent/broken: `CLAUDE_PLUGIN_ROOT` fixture without
|
||||
the checker script → announce byte-identical to pre-change output.
|
||||
|
||||
The test file joins the local pytest manifest in the same commit (local/CI parity
|
||||
discipline per #492).
|
||||
|
||||
### Docs
|
||||
|
||||
- `docs/SETUP.md` Method 0: after the auto-update recommendation, add that from the
|
||||
release shipping #544 onward the plugin announces at session start when a newer
|
||||
version exists, the `ARS_UPDATE_CHECK=0` kill switch, and the privacy note (exact
|
||||
version number is filled in at release time, not hardcoded ahead of the tag). Mirror the sentence in
|
||||
`docs/SETUP.zh-TW.md` (en/zh parity: no H2 change, prose only).
|
||||
- `CHANGELOG.md` `[Unreleased]` entry citing #543 → #544.
|
||||
|
||||
### Explicitly out of scope
|
||||
|
||||
- Clone/symlink install coverage (see Scope decision).
|
||||
- Snooze/backoff ladder, "just upgraded" banner, interactive upgrade prompt.
|
||||
- Semver ordering (string inequality is the correct question here).
|
||||
- Auto-running the update (Claude cannot invoke `/plugin update`; the platform owns it).
|
||||
- Adding the checker to `INFRA_PROTECTED_GLOBS` — it is advisory announce plumbing,
|
||||
not load-bearing enforcement; protecting it would repeat the #459 category error.
|
||||
|
||||
## Invariants
|
||||
|
||||
1. With `ARS_UPDATE_CHECK=0`, or outside a plugin install, or on any failure path,
|
||||
the announce output is byte-identical to pre-#544 behavior.
|
||||
2. The checker performs at most one network request per session start with a 3 s
|
||||
ceiling — and in steady state (no local version change, healthy cache) at most
|
||||
one per 24 h per machine. It never blocks or breaks session start.
|
||||
3. All human-facing reminder wording lives in `announce-ars-loaded.sh`; the checker
|
||||
emits only the machine token.
|
||||
4. The check transmits no user data; the only network access is an HTTPS GET of one
|
||||
public repo file.
