Keep paperclip-docs in lockstep with the parent paperclipai/paperclip codebase. Detects code-surface changes (CLI, env vars, API routes, adapters, plugin SDK, schemas) and produces friendly-tutorial-voice doc updates. Two modes — `nightly` (tracks parent's default branch (currently `master`), targets the `nightly` branch, preview deploy) and `release` (on parent tag, merges nightly → main, tags, ships live). Trigger phrases: "sync docs", "update docs from paperclip", "/sync-docs", "check for paperclip changes", "is docs current".
/sync-docs — Paperclip docs sync skill
This skill keeps paperclip-docs in lockstep with the parent code repo paperclipai/paperclip, rewriting changes in our friendly-tutorial voice for an audience that spans end users, operators, and developers.
Our docs are not a translation of the parent's docs. The parent's code is the source of truth. The parent's release notes and inline docs are reference data for understanding intent.
For the visual model of the branch flow and per-run phases, see maintenance/maintenance.md → Sync workflow → Architecture (two mermaid diagrams). This file is the operational playbook; that file is the picture.
Mental model

The branch model is non-negotiable: end users on the latest released paperclip must never see docs for features that aren't out yet.
Files this skill reads / writes
scripts/sync/anchor-map.json — read-only config: which parent paths to watch, which docs paths they map to, which tier (auto-merge vs PR).
.sync-state.json — read/write: where this branch last left off and what was last applied. Schema: branch_mode, base_release_tag, base_release_sha, last_seen_parent_sha, last_applied_manifest_hash, last_run_at, last_run_outcome.
PENDING.md (on nightly branch only) — regenerated from scratch each run (not appended) so it always reflects the current cumulative manifest. Stale entries from reverted commits never linger.
SCREENSHOTS_PENDING.md (committed) — regenerated each run, lists screenshots whose depends_on paths changed in the diff window.
docs/reference/changelog.md — release mode only: append one accordion entry per release (Phase 6.5). User-facing and linked from the nav; nothing else writes it.
Helper scripts called during the run:
scripts/sync/compare-window.mjs — Phase 2 cumulative diff (handles GitHub compare API truncation via midpoint bisection).
scripts/sync/detect-renames.mjs — Phase 3 directory rename detection (distinguishes a renamed surface from a brand-new one).
scripts/sync/verify-edit.mjs — Phase 5.5 post-edit verification (checks that authored claims still match parent code).
scripts/sync/realign-nightly.mjs — post-release realign (Phase 7): fast-forwards nightly onto the merged release branch and re-anchors the merge-base after the squash-merge severs ancestry.
Invocation
/sync-docs # auto: nightly if no new parent tag, release if new tag
/sync-docs --nightly # force nightly mode
/sync-docs --release # force release mode
/sync-docs --dry-run # triage only, no edits, no commits, no PRs
/sync-docs --since v2026.318.0 # override starting point
/sync-docs --batched # release mode only: one PR per release tag (use for big gaps)
Preconditions to verify before doing anything
gh auth status is logged in (we need GitHub API for parent repo).
Working tree is clean (git status). If dirty, abort and tell the user — never stash their work.
.sync-state.json exists and parses. If missing, abort and tell the user to seed it from scripts/sync/state.example.json.
scripts/sync/anchor-map.json exists and parses.
Resolve parent default branch. Call gh api repos/paperclipai/paperclip -q '.default_branch' once at the start of the run and store the result in a local variable referenced below as <parent-default>. As of this writing it returns master, but capturing it dynamically means the skill keeps working if the parent ever renames to main. All subsequent references to "parent's main HEAD" / "parent main HEAD" in this skill resolve to <parent-default>.
Preflight watcher paths. For every concrete (non-glob) path in anchor-map.json watchers' parent_paths, call gh api repos/paperclipai/paperclip/contents/<path> --silent and warn (do not fail) on 404. This catches stale path entries like the server/src/env.ts case found in the design dry-run — surface them in the run summary so the human can update anchor-map.json.
Step-by-step
Phase 1 — Decide mode and target branch
Read .sync-state.json. Note branch_mode and base_release_tag.
Fetch parent's latest release: gh api repos/paperclipai/paperclip/releases/latest -q '.tag_name'.
Auto-detect mode (unless overridden):
If a new release tag exists AND base_release_tag is older → release mode.
Otherwise → nightly mode.
Check out the right branch:
Release mode: ensure on main. Release mode is self-sufficient — it does not require the nightly branch to exist or to have drafts. If nightly exists with relevant drafts, they're used as a starting point; if not, the release run computes everything from scratch.
Nightly mode: ensure on nightly. If nightly doesn't exist, create it from main.
Nightly mode only: merge main into nightly first to absorb any hot-fix typos that landed on released docs. Resolve trivially or abort if conflicts need human attention.
Ancestry guard (squash-only repo). Before merging, check git merge-base --is-ancestor <last release squash commit> nightly — practically: does the merge produce add/add conflicts on pages both branches created? This repo squash-merges release PRs, which severs the ancestry between main and nightly; if the post-release realign was skipped, this merge explodes into add/add conflicts on every page nightly drafted that cycle. If that happens, do NOT resolve by hand — abort and run node scripts/sync/realign-nightly.mjs <release-branch> (see Phase 8 and the special case below), then retry.
Phase 2 — Resolve the diff window (cumulative)
Both modes use cumulative diffs — always from a stable base, never incrementally from yesterday. This makes reverts auto-cancel (they're net-zero in the cumulative diff) and lets nightly be safely regenerated.
Release mode: prev = state.base_release_tag, next = latest release tag. Build a list of intermediate tags so --batched can produce one PR per tag.
Nightly mode: prev = state.base_release_tag (NOT yesterday's SHA), next = parent HEAD. Then apply quarantine: ignore any commits younger than quarantine_hours (default 24) so reverts have time to land before we process the original.
Cache result under /tmp/paperclip-sync/<sha>/ so we don't refetch within a run.
Pagination & truncation. The GitHub compare endpoint caps responses at 300 files / 250 commits. Use the helper that handles recursive midpoint bisection by SHA:
Returns { from, to, total_commits_seen, leaves, truncated_leaves, files: [...] }. truncated_leaves MUST be 0 in a successful run; non-zero means a leaf still hit the cap (should be impossible) and the run should abort with that fact in the summary.
The script applies these status-merge rules when unioning leaf file lists: added+removed → drop; added+modified → modified; modified+removed → removed; renamed wins over modified. Latest-seen status wins otherwise.
Leaf responses are cached under /tmp/paperclip-sync/ so re-runs within a day are cheap.
Why cumulative, not incremental? If we diffed yesterday → today, a revert commit landing today would need to be processed to undo yesterday's doc edit — and filtering revert commits by message regex would lose that signal. With cumulative diffs from the last release, reverts simply aren't in the diff at all. The original commit and its revert cancel out before we ever see them.
Phase 1.5 — Drift check (independent of diff window)
Drift is the inverse of the cumulative diff: it's the set of things we already document that have since vanished or moved upstream. It exists regardless of when the last sync happened — a parent surface can disappear between two sync runs even if our diff window is empty. The wet-run that motivated this phase found POST /api/companies/{companyId}/logo documented but absent from current server/src/routes/companies.ts, with no sign of it in any diff window the sync had ever processed.
The script scans docs/** for four reference classes and verifies each one still exists in parent:
Class
What we scan
Confidence
parent-path-missing
cli/src/..., server/src/..., packages/<name>/..., skills/paperclip/... references with .ts/.mjs/.js extensions
high
cli-command-missing
paperclipai <subcommand> invocations under docs/reference/cli/**
high
env-var-missing
Rows in docs/reference/deploy/environment-variables.md
high
rest-route-missing
GET/POST/PUT/PATCH/DELETE /api/... headers under docs/reference/api/**
medium
Output is structured JSON with a drift array of records: kind, doc (file:line), documented, parent_searched, confidence, suggest. The script always exits 0 — drift is a warning, never a hard failure. Results are cached under /tmp/paperclip-sync/drift-<ref>/ so re-runs within a day are cheap.
Where drift records go. They join the change manifest as a separate drift tier — not auto-merge, not pr, not context-only. They have their own category because they're driven by what's missing from parent, not by what changed in a window.
Never auto-resolve drift. Even high-confidence drift requires human judgement: a missing route may have been moved (update the doc) or removed (delete the section). Always surface drift to the human:
In the run summary (Phase 4 / Phase 8).
In PENDING.md under a "⚠ Drift" section (nightly mode).
In the PR body under a "⚠ Drift" heading (release mode).
Confidence handling in the summary. High-confidence findings (parent paths, CLI commands, env vars) get prominent placement at the top of the drift section. Medium-confidence findings (REST routes — route prefixing and dynamic registration can hide real matches) are prefixed with Verify: so reviewers know to spot-check before acting. The medium tier is intentionally noisy on the side of caution.
If --dry-run is set, drift candidates are printed alongside the rest of the manifest summary and the run stops there.
Phase 3 — Surface diff (the change manifest)
For each watcher in anchor-map.json:
Intersect the changed-files list with the watcher's parent_paths globs.
For matching files, apply the watcher's detection rule (descriptions in anchor-map.json's detect field — interpret semantically, you're not running grep blindly).
Rename pass. Before finalising entries that look like "new doc page for a brand-new top-level dir" (especially under the adapters, agent-skills, server-adapters, plugin-sdk watchers), run:
Detected rename (renamed_from → renamed_to): do NOT emit a "new doc page" entry for the renamed_to dir. Instead route the entry to the existing doc page for the renamed_from dir with change_kind: renamed and an evidence line that includes the helper's confidence and signal fields.
added_dirs_genuinely_new: proceed as the existing rules say — emit a "new page" entry mirroring a neighbour.
removed_dirs_no_match: surface as a ⚠ Reconcile-style flag (a documented surface vanished upstream with no rename target — the human decides whether to remove or archive the doc page).
Output a structured entry:
-watcher:cli-commandsparent_files: [cli/src/commands/worktree.ts]
change_kind:added# added | modified | renamed | removedsurface:"paperclipai worktree prune"evidence:"New program.command('prune') call at line 84"docs_targets: [docs/reference/cli/worktree.md]
tier:prparent_commits: [a1b2c3d, e4f5g6h]
release_context:"v2026.319.0 — Highlights: 'Worktree pruning for orphaned dirs'"
Filter the change manifest:
Drop watcher-context-only entries (they only feed framing into other entries).
Sort by tier (auto-merge first, then PR).
We do not filter commits by message regex. No skip_patterns. The cumulative diff already filters by outcome (a reverted commit's net change is zero, so it's not in the diff). Filtering by commit-message regex would dangerously hide undo signals — see the warning in Phase 2.
Write the manifest to /tmp/paperclip-sync/manifest.yaml and, in nightly mode, regeneratePENDING.md at repo root from this manifest (overwrite — do not append). Compute manifest_hash = sha256(canonical manifest yaml) for use in the reconciliation step below.
Phase 3.5 — Reconciliation (catches reverts of previously-applied changes)
Cumulative diffs prevent us from making new wrong edits, but they don't automatically undo edits we already committed in a prior run for a feature that has since been reverted.
Compare manifest_hash to state.last_applied_manifest_hash. If equal → nothing changed since last run, skip to Phase 6.
Compute the manifest delta:
New entries (in current, not in last) → normal apply in Phase 5.
Disappeared entries (in last, not in current) → reconciliation candidates. A doc edit was made previously for something that's no longer in the cumulative diff. Most likely cause: the parent commit was reverted.
For each disappeared entry, emit a reconciliation flag with the original watcher, target docs path, and the now-vanished parent commits. Do not auto-undo the doc edit — surface it to the user in the run summary and (if writing a PR) in the PR body under a "⚠ Reconcile" section. Manual review decides whether the doc edit should be reverted.
This is the fail-safe: even if a revert lands between runs, the user gets a clear "the feature you documented yesterday no longer exists upstream" alert at the next run.
Phase 4 — Dry-run gate
If --dry-run: print the manifest summary, no further action. Always show:
Total changed parent files in window.
Manifest entries by tier.
Auto-merge candidates (count + bullet list).
PR candidates (count + bullet list).
Reconciliation candidates from Phase 3.5 (disappeared entries).
Drift candidates from Phase 1.5 — grouped by kind, high-confidence first, medium-confidence prefixed with Verify:.
Screenshot staleness flags (from Phase 6).
Stop here.
Phase 5 — Apply edits
For each manifest entry, top-down:
Auto-merge tier (only if it passes auto_merge_safety in anchor-map.json):
Safety gates, checked in order — failing ANY demotes the entry to PR tier:
change_kind must NOT be in auto_merge_safety.forbid_kinds (default: removed, renamed). A 1-line rename is still a breaking change.
If all pass: make the mechanical edit directly. Examples: append a row to environment-variables.md, add an adapter name to an enumerated list. Never rewrite prose under this tier — that's PR tier by definition.
Batched-release mode is exhaustive. In --batched release mode, every doc-relevant manifest entry in EACH window must be processed — no subsampling. This is the equivalent of how nightly mode handles every entry of its cumulative manifest. Wet-run subsampling (e.g. "pick 2 representative entries") was scope-control for testing, not skill design. Skipping entries in real catchup runs leaves docs incomplete. Per-window tier classification still applies — auto-merge and PR entries both get processed; the only thing that varies is how many entries each window contains (some releases are small).
Builder note.site/build-release.mjs strips YAML frontmatter from the rendered markdown body and surfaces parsed fields into content.json. paperclip_version is internal metadata only — the SPA does NOT render it on-page. Authored pages SHOULD still include paperclip_version in release mode so the field is queryable from content.json (e.g., to drive future per-page version badges or release-PR diff tooling) and so the source of truth for "which release does this page document" lives next to the prose.
PR tier (judgment calls):
Spawn a subagent per entry, in parallel where possible. Give each:
The manifest entry.
The relevant parent code (read-only — fetch via gh api .../contents/<path>, do not clone full parent).
The current state of the target docs file(s).
One neighbouring doc page as a tone/structure reference (e.g. for a new adapter, pass the closest existing adapter page).
The release-context line if release mode.
Subagent's instruction (paste this verbatim when spawning):
Rewrite the target docs file(s) to incorporate the change described in the manifest entry. Voice rules:
Friendly-tutorial style. Audience is everyone — end users, operators, developers — not only devs.
Lead with the user's goal, then the mechanics.
Use second person ("you can…"), present tense, short paragraphs.
Never paste from the parent repo's own docs. Their tone is dev-focused; ours is not.
Preserve existing page structure unless the change demands new sections. Keep cross-references intact.
If a new page is needed, mirror the structure of the neighbour page you were given. Do NOT edit site/content.json directly — return a nav_addition structured object alongside the page content (see below). The orchestrator will merge it.
Add paperclip_version: <tag> to the frontmatter of touched pages in release mode; leave alone in nightly mode (nightly pages are versionless until they merge to main).
Every concrete claim you write (CLI flag names, env var names, REST route paths, config field names, file paths) must come from the parent code you were given. Do not infer or paraphrase identifiers; copy them verbatim. The next phase verifies these claims against parent code.
Return: { "files": { "<path>": "<new content>" }, "nav_addition": { "section_title": "How-to Guides", "entry": { "title": "...", "file": "../docs/how-to/foo.md" } } } — nav_addition is null if no new page was created.
After all subagents return, the orchestrator (this skill, on the main thread) serialises the site/content.json merge: collect all nav_addition results, then make a single coordinated edit to content.json. Subagents never write content.json directly — this prevents the race where two parallel subagents clobber each other's nav entries.
Phase 5.5 — Verify edits against parent code
For every file touched in Phase 5 (auto-merge or PR-tier):
Collect all unverified and suspicious records into a Verification Report for the run.
Routing rules:
Auto-merge tier edits. If any high-confidence unverified record fires (kind ∈ {cli-command, env-var, file-path}), roll back the edit — auto-merge is mechanical and should have been right. Surface the failed entry in the run summary.
PR tier edits (nightly mode). If any high-confidence unverified record fires, demote the entry from auto-commit to PR draft and add a ⚠ Verification Failed callout in the PR body listing each unverified record. The human reviews and corrects.
PR tier edits (batched-release mode). Never auto-merge if any unverified records exist. They flow into the release PR with the failed claims listed under ⚠ Verification Failures.
Suspicious records. Logged and surfaced in the run summary / PR body, but never block. They're informational.
Phase 6 — Screenshot staleness check
Read docs/user-guides/screenshots/registry.json. For each entry:
Compare its captured_sha against the current parent ref.
If any of the entry's depends_on parent paths changed in the window → mark stale.
Output stale entries to SCREENSHOTS_PENDING.md (committed) and to the PR/commit body.
Capture is now automatable via the screenshot pipeline:
Normal refresh (recaptures only stale entries, or everything if no filter is applied):
npm run screenshots:refresh
Full overhaul (recaptures every screenshot — use after a major UI/UX redesign):
npm run screenshots:refresh:all
Both commands spin up an isolated local_trusted / loopback Paperclip instance, seed it with demo data, capture light + dark variants at 1440×900 @2x, and stamp captured_sha / captured_against in registry.json. The output PNGs land in a PR for human review — they are never auto-pushed. See scripts/screenshots/README.md for prerequisites and full details.
docs/reference/changelog.md is a changelog for these docs — pages added,
rewritten, or expanded per release — not for the product. It is user-facing and
linked from the nav, and nothing else writes it, so it silently goes stale unless
this phase runs. (It did: the page was created in July 2026 with two backfilled
entries and then missed the very next release.)
Skip entirely in nightly mode — nightly pages are versionless until they merge to
main, and a changelog entry for an unreleased tag would leak.
Read the current top entry to match its shape. The format is a <details>
accordion, newest first:
<detailsclass="accordion"open><summary>Docs for vYYYY.MDD.P <spanclass="accordion-meta">Month D, YYYY</span></summary><divclass="accordion-body">
**New pages**
- [Title](relative/path.md) — one line on what it covers.
**Updated pages**
- [Title](relative/path.md) — one line on what changed.
</div></details>
Only the newest entry carries open. Remove open from the previous top
entry when you insert the new one, or the page renders with two expanded.
Build the entry from the manifest you already have, not from a fresh diff:
New pages — every page created this window. Link text is the page title.
Updated pages — the substantive rewrites. Lead with the reader's benefit
("what an agent may propose, and the board-side approve/reject flow"), not
the mechanics of the diff. Roll trivial one-liners into a single trailing
bullet rather than listing each.
Screenshots — add a short block when a release recaptured them, saying
what was reshot and what gained first-time coverage.
Links are relative to docs/reference/: a sibling is api/secrets.md, a page
elsewhere under docs/ is ../guides/day-to-day/decisions.md.
Bump the page's own paperclip_version frontmatter to the release tag.
Exclude maintenance files that are not user-facing pages (anything under
docs/user-guides/screenshots/, SCREENSHOTS_*.md, plan documents). They are
in the repo, not in the docs.
Phase 7's sync:check catches a bad relative link here, so a typo fails the run
rather than shipping.
Phase 7 — Verify & commit
Run npm run docs:build. Fail loud on build errors — do not commit.
Run npm run sync:check (lint-links + verify-nav). Dangling nav entries or broken internal links → fail loud, do not commit. Orphans (md files not in content.json) are warnings — surface in the run summary so the user can decide whether the orphan is intentional (a maintenance file) or a missed registration.
Nightly PR-tier edits → branch nightly-draft/<short-sha>-<surface> off nightly, open PR against nightly.
Release mode → branch release/v2026.X.Y off nightly, open PR against main titled Release docs for paperclip v2026.X.Y. PR body = manifest + screenshot staleness + structured sections (below) + checklist.
Squash-merge consequence. This repo is squash-only (gh pr merge --squash). Squashing the release PR breaks the ancestry between main and nightly — the squash commit has no parent link to the nightly commits that produced it. Therefore, immediately after the release PR merges, run:
It fast-forwards nightly onto the release branch, merges origin/main back in to re-anchor the merge-base at the squash commit, verifies main's tip is an ancestor of nightly, and pushes. Skipping this arms an add/add conflict trap that detonates at the next nightly run (see the special case below). Do not run any nightly-mode sync between the squash-merge and the realign.
PR body structured sections (each omitted if empty — never silently dropped):
### ⚠ Drift — every drift candidate from Phase 1.5 grouped by kind, high-confidence first, medium-confidence prefixed with Verify:. Never auto-resolved — the PR explicitly asks the reviewer to act on each entry (update path, delete section, or confirm false positive).
### ⚠ Verification Failures — every unverified record from Phase 5.5, with the doc location (file:line) and the helper's suggest field. Reviewer corrects before merge.
### ↻ Renames detected — every directory rename from Phase 3, formatted <from> → <to> with the helper's confidence and signal. Confirms that no spurious new doc pages were created for a renamed surface.
Update .sync-state.json:
{"branch_mode":"<nightly|release>","base_release_tag":"<unchanged in nightly mode; bumped to new tag on successful release merge>","base_release_sha":"<parent sha at base_release_tag>","last_seen_parent_sha":"<parent `<parent-default>` HEAD at this run — informational only>","last_applied_manifest_hash":"<sha256 of the manifest just applied>","last_run_at":"<ISO timestamp>","last_run_outcome":"<applied|dry-run|no-changes|error|reconcile-needed>"}
base_release_tag only changes on a successful release merge to main. Nightly never bumps it — that's the invariant that makes cumulative diffs stable.
Commit the state update on top.
Phase 8 — Hand off
Never push without asking. Always end the run by printing:
The branch you're on.
The commits/PRs you created (with URLs if PRs were opened).
Anything that needs human attention (PR-tier drafts, stale screenshots, build warnings).
Ask: "Push these changes / open the PR?"
Special cases
First-ever run / large gap
Use --batched in release mode if more than 2 release tags are between base_release_tag and latest. Produces one PR per tag. Easier to review, easier to revert a single bad release.
Reverts of unprocessed commits
The cumulative diff window means a feature commit and its revert cancel out before they reach the manifest. Combined with the 24h quarantine, most reverts never produce churn.
Reverts of already-applied commits
Handled by Phase 3.5 reconciliation. If we previously committed a doc edit and the parent feature has since been reverted, the disappeared entry surfaces as a "⚠ Reconcile" flag in the run summary / PR body. The skill does NOT auto-undo doc edits — manual review is required, because the "undo" may itself be a friendly-tutorial rewrite that's hard to invert mechanically.
Half-built features on parent main
By design, nightly drafts in PR tier so half-built features don't auto-land on live docs. Auto-merge tier is restricted to schema-bound additions which by definition can't be "half-built" (the env var either exists in .env.example or it doesn't).
Hot-fix on released docs (e.g. typo on main)
Fix directly on main of this repo. The skill's "merge main into nightly at start of each run" rule keeps the branches aligned automatically.
Renames on parent (e.g. cli/src/commands → apps/cli/src/cmds)
Anchor-map watchers will report "no changes detected" for many runs even though parent is clearly active. Fix anchor-map.json to the new paths. The next run will pick up the cumulative diff against the new paths correctly.
Release PR was squashed and nightly was not realigned
Symptom: the next nightly run's "merge main into nightly" fails with add/add conflicts on pages both branches created (nightly's unstamped drafts vs main's release-stamped copies). Cause: this repo is squash-only, so the release squash commit has no ancestry link back to nightly, and the realign step (Phase 7) was skipped. Recovery: abort the merge (git merge --abort), then run node scripts/sync/realign-nightly.mjs <release-branch> --push. If the local release branch was already deleted, recreate it from the last pre-merge SHA (git branch release/vX.Y.Z <sha> — find it in the merged PR's head) or, if main has had no commits since the squash, git checkout nightly && git merge origin/main -X theirs is NOT safe (it can silently drop post-tag nightly drafts) — prefer recreating the branch. Never git reset --hard origin/main on nightly: it destroys drafts for parent features that shipped after the release tag.
Nightly branch has open PRs against it when a release ships
The release PR merges nightly → main. If there are open nightly-draft PRs, they get included in the release if merged into nightly first, or remain on nightly for the next release cycle if not. The skill should list open nightly-draft/* PRs in the release-PR body so the human reviewer can decide.
What this skill does NOT do
Push to remote. Ever. Without explicit user approval.
Auto-merge PRs. Even auto-merge tier means "auto-commit to nightly branch," not "auto-merge to main."
Generate docs from code by template/codegen. Every doc edit goes through subagent rewriting in our voice.
Copy text from the parent's own docs.
Push screenshots or any other output. npm run screenshots:refresh captures and stamps registry.json, but the resulting PNGs go to a PR for human review — the skill itself never pushes.
Modify site/content.json without a corresponding new doc page (no orphan nav entries).
Delete pages without explicit confirmation, even if a watcher detects a removed surface.
Failure modes & recovery
Failure
Recovery
gh not authed
Abort, tell user to run gh auth login.
Dirty working tree
Abort, tell user. Never stash.
Build fails after edits
Roll back edits in working tree, save manifest to /tmp/paperclip-sync/failed-manifest.yaml, tell user which entry caused it.
Subagent produces something that doesn't match voice rules
Show diff to user, ask before committing.
Conflict merging main into nightly
Abort with clear conflict report, ask user to resolve.
Anchor-map watcher pattern matches nothing for many runs
Note in run summary — likely a parent refactor moved files; suggest user updates anchor-map.json.
Reconciliation flags pending (Phase 3.5)
Surface in run summary and PR body. Do not auto-resolve. The next run still proceeds for non-reconciliation entries.
base_release_tag is older than the parent's oldest available release
Parent may have deleted ancient tags. Abort with instructions to manually update .sync-state.json to the oldest available tag.
Maintenance of this skill
When the parent repo restructures (e.g. moves cli/src/commands → apps/cli/src/cmds), anchor-map.json needs updating. Symptoms: nightly runs report "no changes detected" while parent is clearly active, or surface diffs route to wrong docs paths. Fix the map, not the skill.
When a new product surface ships that doesn't fit any existing watcher (e.g. a new GraphQL endpoint type), add a new watcher entry to anchor-map.json with appropriate tier and detect prose.
