All health dimensions are checked (stale, orphan, dead links, cross-refs, backlinks, citations, filing, tags)
Each issue found has a specific fix action
Back-link iron law is enforced
Citation format is validated against the standard
Results are reported with counts per dimension
Phases
Autonomous path (v0.36.4.0) — when you want to reach a target score
If the user asks "get my brain to 90/100" or "fix what's broken", prefer the
one-command loop over walking each dimension by hand:
gbrain doctor --remediation-plan --json # preview what would run
gbrain doctor --remediate --yes --target-score 90 --max-usd 5
--remediation-plan prints a dependency-ordered list (sync before extract,
embed after consolidate, etc.) with per-step est_seconds and est_usd_cost.
--remediate walks the plan, submitting each step as a Minion job, re-checking
score between every step. --max-usd N is a hard cost cap — submission refuses
when the plan would exceed the cap (prevents synthesize loops from burning
Anthropic credits unattended).
When the target score is unreachable for the brain (empty brain with no entity
pages → graph_coverage caps at 70; unconfigured embedding key → caps at 60),
the command bails with a list of what's missing rather than looping.
Use the per-dimension walk below (Phase 2 onward) when:
The user explicitly asks for a dimension-by-dimension audit
You're investigating why score is stuck below --remediate's ceiling
A specific dimension needs manual judgment that the auto path skips
Manual path
Run health check. Check gbrain health to get the dashboard.
Check each dimension:
Stale pages
Pages where compiled_truth is older than the latest timeline entry. The assessment hasn't been updated to reflect recent evidence.
Check the health output for stale page count
For each stale page: read the page from gbrain, review timeline, determine if compiled_truth needs rewriting
Orphan pages
Pages with zero inbound links. Nobody references them.
Review orphans: are they genuinely isolated or just missing links?
Add links in gbrain from related pages or flag for deletion
Dead links
Links pointing to pages that don't exist.
Remove dead links in gbrain
Missing cross-references
Pages that mention entity names but don't have formal links.
Read compiled_truth from gbrain, extract entity mentions, create links in gbrain
Link graph extraction
If link_count is 0 or low relative to page_count, run batch extraction:
gbrain extract links --dir ~/brain
This scans all markdown files for entity references, See Also sections, and
frontmatter fields, then creates typed links in the database.
Timeline extraction
If timeline_entry_count is 0, extract structured timeline from markdown:
gbrain extract timeline --dir ~/brain
Dream cycle (v0.23): synthesize + patterns
gbrain dream runs the full maintenance cycle (core phases shown; opt-in
phases like atoms/concepts/drift slot in between):
The two new phases consolidate yesterday's conversations into long-term memory:
Synthesize phase (two-stage cascade): reads transcripts from
dream.synthesize.session_corpus_dir, then triages before it spends: a cheap
utility-tier judge (models.dream.triage) scores every new file 0–1 for
salience and pre-extracts candidate quotes + entities, cached in
dream_verdicts with the judging model + prompt version (bounded per cycle
by dream.triage.max_ms, default 5 min — deferred files retry next cycle,
never silently rejected). Only files scoring
at or above dream.triage.threshold (default 0.5 — applied at read time, so
retuning the threshold re-gates with zero new LLM calls) fan out one synthesis
subagent per transcript chunk, each primed with the triage map. By default
each child runs in oneshot mode (dream.synthesize.mode, default oneshot):
ONE tool-less completion against a prompt carrying a pre-retrieved LINK
CANDIDATES manifest (dream.synthesize.link_manifest, default on) and the
write allow-list, validated end-to-end (slug fences, task shapes, wikilinks)
before any page is written programmatically. A response that fails validation
falls back to the classic agentic loop in the same job, where the
dream.synthesize.max_turns cap (default 16) applies; revert dial:
gbrain config set dream.synthesize.mode agentic. Each child writes reflections
(wiki/personal/reflections/...) and originals (wiki/originals/ideas/...);
people timeline entries are written only on the agentic path (fallback or
mode agentic), where the child has the add_timeline_entry tool. The orchestrator collects the slugs from
subagent_tool_executions (NOT pages.updated_at — that would pick up
unrelated writes) and reverse-renders each new page from DB → markdown on
disk. To re-apply the gate after retuning the threshold or drain a queued
backlog, run gbrain dream retriage --dry-run (zero LLM calls, cached
scores only) then gbrain dream retriage --reconcile-queue; --force
re-judges everything from scratch.
Patterns phase: runs after extract (so the graph state is fresh).
Reads recent reflections within dream.patterns.lookback_days (default 30),
runs a single Sonnet pass to surface recurring themes, and writes pattern
pages to wiki/personal/patterns/<theme> when ≥dream.patterns.min_evidence
(default 3) reflections support a pattern.
Quality bar (Iron Law for synthesis):
Quote the user verbatim. Do not paraphrase memorable phrasings.
Cross-reference compulsively: every new page MUST have at least one wikilink.
Slug discipline: lowercase alphanumeric and hyphens only. NO underscores, NO file extensions.
Edited transcripts produce NEW slugs (content-hash suffix changes) — never silently overwrite.
Trust boundary (allowed_slug_prefixes): the synthesis subagent runs with an
explicit allow-list of write paths sourced from _brain-filing-rules.json's
dream_synthesize_paths.globs. Even on prompt-injection success, the subagent
cannot write outside that list. Trust comes from PROTECTED_JOB_NAMES — MCP
cannot submit subagent jobs at all. Editing the JSON is the only way to add
a new directory the synthesizer can write to.
Idempotency + privacy: transcripts are keyed by (file_path, content_hash),
so re-running on the same content is a no-op. dream.synthesize.exclude_patterns
(default ["medical", "therapy"]) filters out transcripts before any LLM call.
Each entry is auto-wrapped as a word-boundary regex (e.g. medical matches
"medical advice" but NOT "comedical"). Power users may pass full regex.
Cooldown: the cycle's spend cap. dream.synthesize.cooldown_hours (default
12) means at most ~2 synthesize runs per day under autopilot. The completion
timestamp is stored in dream.synthesize.last_completion_ts and is written
ONLY on successful runs (not on skipped/failed). Explicit --input /
--date / --from / --to invocations bypass cooldown.
--dry-run semantics: runs the scored triage pass (judges + caches
verdicts for new files) but skips the synthesis subagents. NOT zero LLM
calls — for a zero-call preview from cached scores use
gbrain dream retriage --dry-run instead.
Configure synthesize on a fresh brain:
gbrain config set dream.synthesize.session_corpus_dir /path/to/transcripts
gbrain config set dream.synthesize.enabled true
gbrain dream --phase synthesize --dry-run --json # preview
gbrain dream # full cycle
Invocation patterns:
gbrain dream # full cycle
gbrain dream --phase synthesize # just synthesize
gbrain dream --phase patterns # just patterns
gbrain dream --input ~/transcripts/2026-04-25.txt # ad-hoc one transcript
gbrain dream --from 2026-04-01 --to 2026-04-25 # backfill range
gbrain dream --json # CycleReport JSON
Auto-commit deferred to v1.1: v1 writes files to brain_dir but does NOT
git add / commit / push. Either commit yourself or let gbrain autopilot
handle it.

Note: extracted entries improve structured queries (gbrain timeline), not vector search.
Autopilot check
Verify autopilot is running:
gbrain autopilot --status
The exit code is trustworthy for gating: 0 fresh (or nothing installed),
1 needs attention (stale heartbeat, never ran, or paused by a migration),
2 the daemon disabled itself (its repo path vanished). --json emits the
full report (state, heartbeat_age_seconds, paused_reason,
disabled_reason). Status reads only the filesystem, so it works even
when the database is down.
If not running, install it:
gbrain autopilot --install --repo ~/brain
Autopilot runs sync, extract, and embed in a continuous loop with adaptive scheduling.
In v0.11.1+, autopilot dispatches each cycle as a single autopilot-cycle
Minion job and supervises the worker child — one install step gives you
sync + extract + embed + backlinks + durable job processing.
Fix a half-migrated install
A v0.11.0 install where the migration skill never fired leaves Minions
partially set up: schema is applied, but ~/.gbrain/preferences.json
doesn't exist, autopilot runs inline, host manifests still reference
agentTurn. Repair:
# Check migration status
gbrain apply-migrations --list
# Apply pending migrations (idempotent; safe on healthy installs)
gbrain apply-migrations --yes# If host-specific handlers are flagged in ~/.gbrain/migrations/pending-host-work.jsonl:# walk them per skills/migrations/v0.11.0.md + docs/guides/plugin-handlers.md,# ship handler registrations in the host repo, then re-run apply-migrations.
Full troubleshooting guide: docs/guides/minions-fix.md.
Back-link enforcement
Check that the back-linking iron law is being followed:
For each recently updated page, check if entities mentioned in it have
corresponding back-links FROM those entity pages
A mention without a back-link is a broken brain
Fix: add the missing back-link to the entity's Timeline or See Also section
Check for common misfiling patterns (see skills/_brain-filing-rules.md):
Content with clear primary subjects filed in sources/ instead of the
appropriate directory (people/, companies/, concepts/, etc.)
Use gbrain search to find pages in sources/ that reference specific
people, companies, or concepts -- these may be misfiled
Flag misfiled pages for review or re-filing
Citation audit
Spot-check pages for missing [Source: ...] citations:
Read 5-10 recently updated pages
Check that compiled truth (above the line) has inline citations
Check that timeline entries have source attribution
Flag pages where facts appear without provenance
Tag consistency
Inconsistent tagging (e.g., "vc" vs "venture-capital", "ai" vs "artificial-intelligence").
Standardize to the most common variant using gbrain tag operations
Graph population (v0.10.3+)
The links and timeline_entries tables are the structured graph layer.
Populate them periodically or after major imports:
gbrain extract links --source db — backfill structured links by walking pages
from the engine. Reads [Name](people/slug) / [Name](companies/slug) references
and infers relationship types (attended, works_at, invested_in, founded,
advises, mentions, source). Idempotent. Use --source fs --dir <brain>
if you have a markdown checkout to walk instead.
gbrain graph-query <slug> --depth 2 — verify connectivity (use any well-known
entity slug as a probe).
gbrain stats — verify link_count > 0 and timeline_entry_count > 0 after extraction.
gbrain health — review link_coverage and timeline_coverage percentages
on entity pages (person/company). Below 50% means more extraction is needed.
On brains with very few entity pages these report "too few to grade"
(null in JSON, with entity_page_count carrying the denominator) instead
of a misleading 0%/100% — grow the entity set before acting on coverage.
Available link types (use with gbrain graph-query --type):
attended, works_at, invested_in, founded, advises, mentions, source.
Going forward, every gbrain put call auto-creates and reconciles links via the
auto-link post-hook (default on; disable: gbrain config set auto_link false).
So link-extract is mostly a one-time backfill. timeline-extract should be re-run
after bulk imports or content edits that add new dated entries.
Feature adoption check (weekly)
gbrain features --json # scan for underused features + recommendations
Run weekly alongside lint. Surfaces missing embeddings, unused integrations,
and configuration improvements.
Embedding freshness
Chunks without embeddings, or chunks embedded with an old model.
For large embedding refreshes (>1000 chunks), use nohup:
nohup gbrain embed refresh > /tmp/gbrain-embed.log 2>&1 &
Then check progress: tail -1 /tmp/gbrain-embed.log
Security (RLS verification)
Run gbrain doctor --json and check the RLS status.
All tables should show RLS enabled. If not, run gbrain init again.
Schema health
Check that the schema version is up to date. gbrain doctor --json reports
the current version vs expected. If behind, gbrain init runs migrations
automatically.
File storage health
Check the integrity of stored files and redirect pointers:
Run gbrain files verify to check all DB records have valid data
Run gbrain files status to see migration state (local, mirrored, redirected)
Check for orphan .redirect.yaml pointers that reference missing storage files
Check for large binary files (>= 100 MB) still in git that should be in cloud storage
If storage backend is configured: verify redirect pointers resolve (download test)
Open threads
Timeline items older than 30 days with unresolved action items.
Flag for review
Benchmark Testing
Periodically verify search quality hasn't regressed. Run a battery of test
queries across difficulty tiers:
Tier 1 (entity lookup): known names -- should always resolve
Tier 3 (semantic): queries with no exact keyword match -- needs embeddings
Tier 4 (cross-domain): relational/connection queries -- only semantic handles
Compare results from gbrain search (keyword) vs gbrain query (hybrid).
Quality matters more than speed (2.5s right > 200ms wrong).
When to run benchmarks:
After major brain imports or re-imports
After gbrain version upgrades
After embedding regeneration
Monthly to track quality drift
Heartbeat Integration
For production agents running on a schedule, integrate gbrain health checks into
your operational heartbeat.
On every heartbeat (hourly or per-session)
Run gbrain doctor --json and check for degradation. Report any failing checks
to the user. Key signals: connection health, schema version, RLS status, embedding
staleness.
Weekly maintenance
Run gbrain embed --stale to refresh embeddings for pages that have changed since
their last embedding. For large brains (>5000 pages), run this with nohup:
Verify sync is running: check gbrain stats and confirm last_sync is within
the last 24 hours. If sync has stopped, the brain is drifting from the repo.
Stale compiled truth detection
Flag pages where compiled truth is >30 days old but the timeline has recent entries.
This means new evidence exists that hasn't been synthesized. These pages need a
compiled truth rewrite (see the maintain workflow above).
Report Storage
After maintenance runs, save a report:
Health check results (before/after scores for each dimension)
Back-link violations found and fixed
Filing rule violations found
Citation gaps flagged
Benchmark results (if run)
Outstanding issues requiring user attention
This creates an audit trail for brain health over time.
Quality Rules
Never delete pages without confirmation
Log all changes via timeline entries
Check gbrain health before and after to show improvement
Anti-Patterns
Fixing pages without reading them first -- you must understand context before editing
Silently skipping dimensions -- every dimension must be checked and reported, even if clean
Deleting orphan pages without checking if they should be linked instead
Running embedding refresh during peak usage hours
Batch-fixing back-links without verifying the relationship is real
Marking a dimension "clean" without actually querying it
Rewriting compiled truth without reading the full timeline first
Removing tags without checking if other pages use the same tag consistently
