| name | brain-write-macro |
| description | Explicit save macro — when user says 'guarda en gbrain' (and 23 phrase variants in ES/EN), automatically extract entities, decisions, originals, and links from the conversation and write them as gbrain pages. Companion to signal-detector (which captures passively per-message); brain-write-macro is the explicit user-triggered version that works in clients without hooks (Claude Desktop, claude.ai web, mobile). |
| allowed-tools | Bash Read Write |
| user-invocable | false |
| companion-skills | signal-detector gbrain |
| custom-instructions-version | 4.1 |
| custom-instructions-changelog | v1 (2026-04-28 03:30): initial — phrase trigger, put_page, add_link, slug list confirm
v2 (2026-04-28 05:42): added CHECK BEFORE WRITE (get_page+merge), explicit type frontmatter,
ASCII slug rules (no accents), trigger exclusions (file/Drive saves),
(new)/(enriched) markers in confirm output, error reporting on tool failure
v3 (2026-05-01 22:00): R1 conflict-flag (no overwrite when get_page returns contradicting field —
append "## Posible contradicción" block instead),
R2 source-tracking (frontmatter `sources: [{date, channel, session_id}]`
replaces the old "merged-from-chatbot" tag pattern),
extended page types (concept, project, recipe, source) and link types
(owns, collaborates_with, superseded_by, mentioned_in, subject_of,
negotiating, advises) — to be hydrated dynamically from gbrain via
`/gbrain custom-instructions --adaptive`,
meta-content guard (rule 7) — never write a page whose body describes
the conversation rather than the entity.
v4 (2026-05-11 01:50): R5 SEARCH side rule made PREFLIGHT and BROAD — fires on bare "busca"
(not only "busca en gbrain"), on recall verbs ("qué tenía sobre X",
"recuérdame Y"), and on implicit references to user's own data.
v4.1 (2026-05-11 02:00): R5 phrasing restored to Sergio's elegant pre-v4 catch-all
"or asks about past conversations / people / companies / decisions /
projects / tasks" — covers same breadth as v4 in 1 line vs 3 sections.
ChatGPT snippet hybrid: keeps tight pre-v4 structure + adds R3 task,
R4 proactive, SKIP rule, full link types. ~1450 chars (vs 1100 pre-v4
and 1800 v4-fragmented).
R3 task-type added (slug `tasks/<short>`, frontmatter status:
pending|in_progress|done|blocked, optional priority/estimated_hours/due_date).
R4 PROACTIVE detection without explicit phrase trigger — when model
detects future project, actionable task, decision, or recurring entity
WITH NEW substantive attributes, offer ONE LINE: "Detecté X. ¿Guardo
como <type>/<slug>?" and wait for yes/no. Never auto-write proactively.
Tasks vs daily-task-manager: tasks/ = captura/pendientes futuros; cuando
se atacan, promover al daily-task-manager flow. Done tasks stay with
timestamp, not auto-archived.

| upstream-status | Not yet in gbrain core. As of 2026-04-28, gbrain has no native "save by phrase" mechanism — it has put_page (manual) + signal-detector skill (per-message ambient). This macro fills the gap for clients without hooks (Desktop/web/mobile).
Auto-disable when: gbrain ships a `gbrain__save_conversation` tool OR a server-side phrase-trigger handler. Recheck via /gbrain Layer 11b which queries `gbrain --help` for those.

/brain-write-macro — Explicit save by phrase (works on every client)
Why this skill exists
The capture gap: GBrain has two automatic capture paths today:
- Claude Code CLI → Stop hook (
~/.claude/settings.json → signal-detector.py) fires at end of every turn, runs Haiku over the transcript, writes pages.
- Telegram (Harviz/OpenClaw) → SOUL.md instructions tell the model to extract entities and call
gbrain__put_page on every inbound message.
But Claude Desktop, Claude.ai web, ChatGPT, and Codex CLI have NO automatic hooks. The model only writes to gbrain if:
- The user pastes Custom Instructions telling it to, OR
- The user explicitly says: "guarda en gbrain"
This skill defines the canonical behavior for the explicit-phrase trigger so all clients implement it identically.
Client delivery map (where instructions live per client)
| Client | How rules are delivered | Format |
|---|
| Claude Code CLI | Stop hook (signal-detector.py) — automatic | Full v3 (embedded in Haiku prompt) |
| claude.ai web/app | Settings → Profile → Custom Instructions | Full v3 (via /gbrain custom-instructions) |
| ChatGPT App | Settings → Personalización → Custom Instructions | Compact v3 (~780 chars, trigger: "guarda en gbrain") |
| Codex CLI | ~/AGENTS.md (gbrain section) | Full v3 (read automatically) |
| OpenClaw / Telegram | SOUL.md + this skill loaded as skill | Full v3 (model reads SKILL.md) |
| Hermes | Inherited via hermes claw migrate | Full v3 (imported skill) |

Trigger phrases (ES + EN)
Activate when user message matches any of these EXACTLY or as a clear intent variation:
| Spanish | English |
|---|
guarda en gbrain | save to brain |
guarda esto en mi brain | save this to brain |
guarda esto en gbrain | save this to gbrain |
lo importante en mi brain | save the important things |
captura en gbrain | capture to gbrain |
mete esto al brain | dump this in the brain |
guarda (after substantive turn) | save (after substantive turn) |
Pattern matching rule: any natural-language combination of the verbs guardar/save/capture/store/dump + gbrain/brain/memory triggers the macro. Don't require exact match — match by intent.
Behavior (canonical procedure — copy-paste this into any agent's system prompt)
Execute this exact sequence WITHOUT asking the user for details. Infer everything from the conversation.
When NOT to trigger (save side)
- File/document save commands: "guarda este archivo", "save the file", "save the doc", "guarda en Drive", "guarda en Notion". Brain capture only.
- Operational noise: pure "ok", "sí", "thanks", "/status".
R5 SEARCH side rule (v4.1 — PREFLIGHT, runs BEFORE everything else, all clients)
This is a PREFLIGHT rule. Apply BEFORE thinking, BEFORE answering, BEFORE save side.
Canonical phrasing (use this exact wording in client snippets — proven elegance + breadth):
When user says "busca", "busca en gbrain", "busca en mi brain", "search gbrain", "search my brain", or asks about past conversations / people / companies / decisions / projects / tasks — ALWAYS call gbrain__search (or gbrain__query for hybrid) FIRST. Never answer from model memory alone.
The "or asks about past..." clause is the catch-all that covers implicit references like "¿quién es X?", "qué decidí sobre Y", "recuérdame Z", "qué pasó con W", "what did we agree on" — any question whose answer lives in the user's personal data.
When in doubt: search first. The cost of an unnecessary gbrain__search call is tiny. The cost of answering from model memory and being wrong is high.
If gbrain returns empty, say so explicitly: "No encontré nada en gbrain sobre X. ¿Lo guardamos?" — don't invent. Optionally connect to R4 proactive detection by offering to create the page.
Why this phrasing: Sergio's pre-v4 ChatGPT snippet already had this catch-all working well. v4 initially fragmented it into 3 verbose categories which lost elegance and char budget without adding coverage. v4.1 restores the elegant phrasing while keeping the PREFLIGHT positioning + the "when in doubt, search" tiebreaker.
Procedure
Step 1 — SCAN this entire conversation (every turn) for:
- People named WITH attributes (role, company, location, age, contact, notable detail). Skip name-only mentions like "I told John" with no other detail.
- Companies/funds/startups WITH attributes (industry, stage, founders, location).
- Decisions the user took or stated ("vamos con X", "decidí Y", "let's go with Z", "no, mejor W", "descartamos…", "elegí…").
- Originals — original ideas, theses, or strategic insights the user framed (not generic Q&A — only the user's own framings). Preserve their exact phrasing in compiled_truth.
Step 2 — SLUG RULES (always):
- Always kebab-case, lowercase, ASCII only. NO accents:
sergio-duran, NOT sergio-durán.
- Format:
people/firstname-lastnamecompanies/<name>decisions/<short-summary>originals/<short-kebab>
Step 3 — CHECK BEFORE WRITE (avoid duplicates) — DO NOT SKIP:
- Before each
gbrain__put_page, call gbrain__get_page with fuzzy: true on the slug.
- If the page exists: READ its current
compiled_truth, then call gbrain__put_page with the merged content (existing + new attributes from this conversation).
- If not found: write fresh.
Step 3.5 — R1 CONFLICT FLAG (NO overwrite on contradiction):
- If a field in the existing page (status, role, company, location, dates, amounts) contradicts the new value from this conversation, do NOT overwrite. Instead, append a block at the end of the page:
## Posible contradicción (YYYY-MM-DD)
- **Field**: <field name, e.g. "status">
- **Valor anterior**: <old value>
- **Valor nuevo**: <new value>
- **Source**: <channel, e.g. "claude.ai web session">
- **Acción**: verificar con Sergio
- Reason: silent overwrite from a partial-context client (claude.ai web, chatbot) is the same class of bug as truncating data — the user must arbitrate.
- Confirm output marks these as
(conflict-flagged) instead of (enriched).
Step 4 — WRITE PAGES with required frontmatter:
gbrain__put_page slug:"people/<...>" type:"person" title:"<Full Name>"gbrain__put_page slug:"companies/<...>" type:"company" title:"<Company Name>"gbrain__put_page slug:"decisions/<...>" type:"decision" title:"<one-line summary>"gbrain__put_page slug:"originals/<...>" type:"original" title:"<short header>"gbrain__put_page slug:"projects/<...>" type:"project" title:"<Project Name>"gbrain__put_page slug:"concepts/<...>" type:"concept" title:"<Concept Header>"gbrain__put_page slug:"recipes/<...>" type:"recipe" title:"<Recipe Header>"gbrain__put_page slug:"tasks/<...>" type:"task" title:"<one-line action>"
- R3 task frontmatter (v4):
status: pending|in_progress|done|blocked, optional priority: low|medium|high, estimated_hours, due_date: YYYY-MM-DD.
- Lifecycle:
tasks/ = captura inicial / pendientes futuros. Cuando el usuario los ataca activamente, se promueven al flujo del skill daily-task-manager. Done tasks quedan con timestamp; no auto-archivadas.
- vs daily-task-manager: ese skill es el flujo diario activo.
tasks/<slug> aquí es el punto de entrada — captura primero, ataca después.
Step 4.5 — R2 SOURCE TRACKING (every put_page includes provenance):
Step 5 — CREATE LINKS for cross-references with gbrain__add_link:
- Person works at Company →
from:"people/x" to:"companies/y" type:"works_at"
- Person co-founded Company →
type:"founded"
- Fund invested in Company →
type:"invested_in"
- Person met with Person →
type:"met_with"
- Person advised Person →
type:"advised"
- Person collaborates with Person →
type:"collaborates_with"
- Company owns Company →
type:"owns"
- Person/Company subject_of Decision/Project →
type:"subject_of"
- Page mentioned_in Source →
type:"mentioned_in"
- Page A superseded_by Page B (rename/consolidation) →
type:"superseded_by"
- Person negotiating with Person/Company →
type:"negotiating"
- Person advises Company →
type:"advises"
NOTE: This list is the static fallback. The canonical, brain-aware list comes from gbrain custom-instructions --adaptive which queries the live page/link types from your brain and injects them into the snippet. Use that whenever possible.
Step 6 — CONFIRM with the actual slugs you wrote AFTER all tool calls succeed:
✅ Guardado en gbrain:
- people/mike-shapiro (new)
- people/jason-prescott (enriched)
- people/sarah-chen (conflict-flagged: status "advisor" vs "investor")
- companies/elafris (new)
- companies/digital-kozak-llc (new)
- decisions/proposed-pool-split-33-30-30-10 (new)
- originals/insurance-vertical-thesis (new)
- 4 links: mike→elafris (founded), mike→digital-kozak (founded), jason→pool-split (proposed), ...
Markers come from Step 3 / Step 3.5:
(new) — get_page returned 404, page written fresh(enriched) — get_page found existing page, content merged(conflict-flagged) — get_page found existing page with a field that contradicts the new value; "Posible contradicción" block appended; user must verify
R4 PROACTIVE detection (v4 — without explicit phrase trigger)
When the user is NOT explicitly saying "guarda", but the conversation contains a substantive signal, offer ONE LINE to the user:
| Pattern | Trigger | Offer |
|---|
| A — future project | "quiero hacer X eventualmente", "deberíamos armar Y", "no urge pero algún día Z", "estaría bueno construir W" | "Detecté un proyecto. ¿Lo guardo como projects/<slug>?" |
| B — actionable task | "tengo que hacer X", "no olvidar Y", "pendiente: Z", "luego hago W" | "Detecté una tarea. ¿Lo guardo como tasks/<slug>?" |
| C — decision | "decidí X", "vamos con Y", "mejor Z que W", "descartamos V" | "Detecté una decisión. ¿Lo guardo como decisions/<slug>?" |
| D — recurring entity | Same person/company in 3+ turns AND with at least ONE NEW substantive attribute (role, company, location, event, decision) — NOT casual mention repetition | "Estamos hablando bastante de X. ¿Guardo página con lo nuevo?" |
Behavior rules:
- Show ONE LINE only. Wait for yes/no.
- NEVER auto-write proactively. Always confirm.
- If user says yes, run the full Procedure (Step 1-6) for that ONE detected item.
- If user ignores the offer (doesn't reply to it), don't repeat. Don't bug.
- Apply quality filter: pattern D requires NEW substantive attribute, not just repetition. "Mi mamá llamó / mi mamá cocinó / mi mamá vino" without new info → don't offer.
Why proactive instead of fully automatic: silent auto-writes from a partial-context client (claude.ai web, ChatGPT) are how garbage gets into the brain. The user is the only authority on what's worth keeping. The 1-line offer is cheap; the user prunes by replying yes/no.
CRITICAL RULES — anti-hallucination
- NEVER respond "guardado" / "saved" / "listo" / "done" without listing actual slugs you called
put_page on. That is hallucination. If you didn't call the tool, don't claim you did.
- NEVER ask "qué quieres que guarde?" / "what should I save?". Infer from the conversation. Better to write 8 pages and let the user prune than to write 0 and ask.
- If a
put_page or add_link call returns an error, report it explicitly:
❌ Failed: people/mike-shapiro — error: <exact error message>
Do NOT pretend it worked. Do NOT silently retry without telling the user.
- For
originals (the user's ideas), preserve exact phrasing in compiled_truth, not paraphrase. Voice matters. The user uses gbrain to retrieve their own words later, not your summary of their words.
- One reply at the end with the slug list. No commentary mid-process. No "let me check..." messages between tool calls.
- NEVER write pages with no attributes. A
people/john with empty body is just noise. Skip name-only mentions entirely.
- NEVER write meta-content as if it were the entity. A page
people/jason-prescott whose body is "User initiated export request..." is wrong — the body is a description of the conversation, not the person. If you don't have substantive attributes about the entity, don't write the page. This rule was added 2026-05-01 after a claude.ai web session created 3 such meta-pages in one turn.
- NEVER overwrite a contradicting field silently (R1). Always flag with the contradiction block. The user is the only authority that can resolve facts.
Verifying capture (debug for the user)
If user later asks "¿se guardó?" / "did it save?":
- Run
gbrain__search with the most distinctive entity name.
- Or
gbrain__get_page on the slug you reported.
- Show first 100 chars of compiled_truth as proof.
If the page does NOT exist: the previous capture failed silently. Apologize and retry.
Ownership map — who owns what for custom instructions
This is the canonical answer to "where do the Claude.ai custom instructions live?":
| Component | Role | File |
|---|
brain-write-macro (this skill) | SOURCE OF TRUTH for the rules. Frontmatter custom-instructions-version is the spec version. The Procedure section IS the custom instructions content. When you bump the version here, every other component below must update or it goes out of sync. | ~/skills/openclaw/brain-write-macro/SKILL.md |
signal-detector (sister skill) | Mirrors the same rules for the per-message Stop hook (Claude Code CLI). Phases 2.5/2.6/2.7 align 1:1 with brain-write-macro Steps 3.5/4.5 + rule 7. | ~/skills/openclaw/signal-detector/SKILL.md |
gbrain skill (run.sh) | EMITS the snippet via /gbrain custom-instructions [--adaptive]. Reads spec version from THIS file's frontmatter. --adaptive injects live page/link types from the brain DB. | ~/skills/shared/gbrain/run.sh (subcommand custom-instructions) |
gbrain-http-wrapper | SERVES the snippet over HTTP at /.well-known/mcp/custom-instructions for clients that can't run a CLI (claude.ai web/app). Same content, JSON-wrapped, served from https://<wrapper-url>/mcp/.well-known/mcp/custom-instructions. | ~/gbrain-http-wrapper/src/server.ts |
/gbrain custom-instructions-applied.flag | Tracks which version the user has actually pasted into claude.ai → Profile. Layer 18 in /gbrain check compares spec vs applied and flags out-of-sync. | ~/.gbrain/custom-instructions-applied.flag |
Layer 18 in /gbrain check | Visualizes all 4 clients (Claude Code CLI, OpenClaw/Telegram, HERMES, Claude.ai web) and which ones are at the current spec version. | ~/skills/shared/gbrain/run.sh (Layer 18 block) |
To bump the spec (e.g. v3 → v4):
- Edit this file's
custom-instructions-version frontmatter and changelog.
- Edit the snippet inside
~/skills/shared/gbrain/run.sh (subcommand custom-instructions, the cat <<'EOF' ... EOF block).
- Edit the snippet inside
~/gbrain-http-wrapper/src/server.ts (the /.well-known/mcp/custom-instructions handler).
- Edit
signal-detector/SKILL.md if the change affects per-message capture.
cd ~/skills && bash install.sh propagates skills to install dirs.sudo systemctl restart gbrain-http-wrapper.service reloads the HTTP endpoint.hermes claw migrate --overwrite --yes --skill-conflict overwrite for HERMES.- User pastes new snippet in claude.ai;
echo <new-version> > ~/.gbrain/custom-instructions-applied.flag.
/gbrain check Layer 18 should show all 4 ✅ and /gbrain integrate claude.ai should show "in sync".
The reason brain-write-macro is the source of truth (and not, say, gbrain skill): this skill is the one that DEFINES what counts as a write to gbrain. The other skills SERVE or DISTRIBUTE the rules — they should always read from here, never define their own version.
Where this skill is referenced
~/SOUL.md Iron Rules section — references this skill by name~/.openclaw/skills/gbrain/run.sh Layer 11b — detects if this skill is installed + checks upstream gbrain for native replacement~/.openclaw/skills/RESOLVER.md (or AGENTS.md routing) — routes user phrase intents here
Auto-deprecation conditions
Disable this skill (move to archive/) when ANY of these become true:
- gbrain CLI ships a
gbrain save-conversation command that does this server-side.
- gbrain MCP server adds a
save_conversation tool that the model can discover and call.
- gbrain integrations registry adds a built-in
phrase-trigger recipe that supersedes this skill.
The /gbrain Layer 11b runs gbrain --help | grep -iE "save-conv|save_conversation|phrase-trigger" weekly — if it finds anything, it suggests deprecating this skill.
