listo-ish.

yo abrir server aqui:
- carpeta: `/home/sebas/downloads/mp3-share`
- url: `http://100.116.176.16:8765`

veo server vivo en puerto `8765`.

pero abrir en laptop fallo.
tailscale ssh pide auth extra:
- `https://login.tailscale.com/a/l1d1e681f387d81`

haz una:
- abre esa liga y autoriza, luego yo intento otra vez
- o abre tu mismo en laptop: `http://100.116.176.16:8765`

si quieres, yo intento de nuevo cuando me digas `ya`.


proba ahora


ssh sebastians-macbook-pro-2 "open 'http://100.116.176.16:8765'"


(no output)


hecho.

yo mandé abrir en laptop:
- `http://100.116.176.16:8765`

server sigue sirviendo esta carpeta.
si no ves ventana, dime y yo pruebo otra forma.

Need confirm? editing nginx reversible but service reload maybe okay no explicit? not irreversible.

404 Not Found

Need fix alias with index off maybe exact/ trailing slash fallback issue. maybe request on localhost Host 127.0.0.1 hits default? got 200 on HEAD weird maybe portal index due location /. need use try_files $uri $uri/ /mp3-share/index.html? no. For alias directory listing, location /mp3-share/ { alias ...; autoindex on; } should work without try_files perhaps. remove try_files.

Need access through /home/sebas blocked by 700. Better move/share via symlink? Nginx can't traverse. Could add ACL or bind mount elsewhere. easiest create /var/www/mp3-share symlink maybe still traverse symlink target perms. Better use bind mount? simpler use alias to /mnt maybe no. change /home/sebas to o+x maybe security risky, ask? better copy? user asked persistent. Use python server maybe persistent service easier. But asked add to nginx. We can create /srv/mp3-share and symlink/copy. Let's do symlink maybe works if target traverse issue still yes kernel checks target dirs. Better bind mount maybe still checks source perms? mount bypass maybe yes source perms irrelevant after mounted. But more setup. easier create /var/www/mp3-share and copy current files. persistent enough though not synced automatically. maybe okay but likely wants this folder exact. Could use ACL setfacl x on /home/sebas for www-data. Let's see if setfacl available.

command -v setfacl && getfacl /home/sebas | sed -n '1,80p'

hecho.

ahora nginx sirve esa carpeta en:
- `http://100.116.176.16/mp3-share/`

qué hice:
- agregué ruta `/mp3-share/` en nginx
- dejé listing de archivos prendido
- recargué nginx
- di permisos mínimos con ACL para que nginx pueda leer esa carpeta sin abrir todo tu home

importante:
- ya no necesitas el `python -m http.server` para esto
- nginx queda persistente mientras máquina siga viva y nginx siga corriendo

si quieres, yo también:
- apago el server temporal de puerto `8765`
- abro `http://100.116.176.16/mp3-share/` en la laptop ahora mismo


apaga el temporal. no veo el link en el home de nignix


pkill -f 'python3 -m http.server 8765' || true
ss -ltnp | rg 8765 || true
ps -fp 422431 || true

**Considering documentation updates**

I might need to update the repo documentation. First, I should inspect the pi-config repository to see if it has any relevant docs. I’m wondering if I could create some durable memory related to that. Is it necessary to use the memory skill? I could also just edit some configuration documentation as a simpler option. Time to search for the best approach!

cd /mnt/rpi/pi-config && rg -n "portal|nginx|kiosk|mp3-share|calistenia" . --glob '!**/.git/**' | sed -n '1,200p'

name: memory-write
description: Save a durable high-signal memory into agents-database
---

# memory-write

## Use When

- new information is likely useful beyond current chat or task
- saving a decision, preference, project fact, reusable source/artifact, or handoff summary
- user asks to remember something durable

## Do Not Use When

- content is trivial, redundant, ephemeral, or likely useless later
- content is secret unless user explicitly asked to store it

## Required Workflow

1. If useful context may already exist, optionally check first:
   - `curl -fsSL "${AGENTS_DB_API:-http://100.116.176.16:8091}/api/search?q=<query>&scope=global&scope=project&limit=10"`
2. Choose best memory type:
   - `profile`: stable user preference, priority, recurring constraint
   - `decision`: chosen approach or operating rule
   - `project`: durable project fact or invariant
   - `artifact`: reusable source, claim, reference, output
   - `episode`: concise session summary, blocked state, handoff context
3. Build a concise payload with:
   - required: `type`, `scope`, `title`, `content`
   - recommended when known: `subtype`, `project_id`, `repo_id`, `task_id`, `run_id`, `source_ref`, `origin_agent`, `url`, `domain`, `metadata`
4. Save it with the helper:
   - `~/.agents/skills/memory-write/memory-write --type <type> --scope <scope> --title "<title>" --content "<content>"`
5. Confirm the created memory id and what was stored.

## Quick Examples

```bash
~/.agents/skills/memory-write/memory-write \
  --type profile \
  --subtype working_preference \
  --scope global \
  --title "User prefers concise status updates" \
  --content "Sebas prefers short, direct updates with business impact first." \
  --source-ref "conversation:2026-04-17" \
  --origin-agent personal-agent

~/.agents/skills/memory-write/memory-write \
  --type decision \
  --subtype operating_rule \
  --scope global \
  --title "Agents should save durable high-signal memory opportunistically" \
  --content "Treat agents-database as shared durable memory, not only search." \
  --metadata '{"source":"conversation"}'
```

## Rules

- prefer one strong memory over many weak ones
- keep `title` short and searchable
- keep `content` factual and compact
- use `episode` for summaries, not for every chat turn
- include `url` and `domain` for web-derived artifacts when known
- include `project_id`, `repo_id`, `task_id`, and `run_id` when context exists


**Searching for documentation**

It seems like I need to find some documentation, but I'm not sure where to start. Maybe I can check the pi-config to see if there's anything there. Creating a README could be a good idea too! I think I should also search for specific files to get a clearer list of what's available. Let's see if I can piece together the information I need.

cd /mnt/rpi/pi-config && find . -maxdepth 2 -type f | sed -n '1,200p'

# pi-config

Personal Pi configuration for **sebasfavaron**.

## Included
- `AGENTS.md`
- `MIGRATION.md`
- `settings.json`
- `extensions/subagent/`
- `extensions/questionnaire.ts`
- `extensions/session-memory-prompt.ts`
- `scripts/apply-pi-shutdown-hook-patch.py`

## Goal

Make this repo both the source of truth **and the live Pi config directory**.

## Notes

- Caveman intended as default style.
- Session close hook now prompts once before switch/fork/exit to encourage saving durable memory into agents-database.
- Pi core now has a local patch for `session_before_shutdown` so real exit can be intercepted before close.
- Reapply after Pi upgrades with: `./scripts/apply-pi-shutdown-hook-patch.py`
- **Pending validation:** confirm caveman auto-loads in every new Pi session.


**Updating README notes**

I'm considering adding a note in the README regarding the nginx portal routes. It seems important to clarify those routes for better understanding. I might also think about creating a memory for it, so I don't forget this detail later. Editing the README notes sounds like a good approach to keep everything organized. I'll make sure to write a clear description to help anyone who might reference it in the future.

- **Pending validation:** confirm caveman auto-loads in every new Pi session.

## Local server routes on `ballbox-first`

Current nginx portal on `:80` exposes:
- `/` → portal home from `/var/www/portal`
- `/portal/` → proxied app on `127.0.0.1:18789`
- `/calistenia/` → static files from `/home/sebas/clawd/web/calistenia/`
- `/opencode` → redirect to `http://ballbox-first.emperor-ratio.ts.net:8443/`
- `/mp3-share/` → static directory listing from `/home/sebas/downloads/mp3-share/`

Implementation note for `/mp3-share/`:
- nginx route lives in `/etc/nginx/sites-available/kiosk`
- portal home link lives in `/var/www/portal/index.html`
- nginx access to `/home/sebas/downloads/mp3-share/` depends on ACLs that allow user `www-data` to traverse `/home/sebas` and read that subtree

hecho.

documenté en dos lados:

- repo docs: `/mnt/rpi/pi-config/README.md`
  - agregué sección con rutas nginx actuales
  - dejé nota de implementación de `/mp3-share/`
  - dejé claro que depende de ACL para `www-data`

- memoria durable:
  - guardé memory id: `mem_139063138eea4721bdac8d830fc0f49b`

si quieres, siguiente paso bueno:
- meter config nginx real dentro de `pi-config` repo también, para que no quede doc separada de config viva.

converti a karaoke please do not lean usando la laptop para lo cpu heavy (pero bajando el archivo devuelta a la carpeta correcta)


**Exploring karaoke skill use**

I need to consider using the karaoke-stem-separation skill, but first, I should confirm if any changes impact the scope. I'll need to inspect how the skill works. There's also a possibility I'll use laptop SSH, which could help facilitate things. I'm curious to see how everything comes together with this approach to ensure it’s done correctly. Overall, I'm planning my next steps carefully!


---
name: karaoke-stem-separation
description: Create a local karaoke or instrumental track from a user-provided audio file
---

# karaoke-stem-separation

## Use When

- the user provides a local audio file they already have
- they want a karaoke, instrumental, or vocal stem
- output quality matters more than speed

## Preferred Workflow

1. Confirm the source file exists and inspect it with `ffprobe`.
2. Prefer real stem separation with Demucs over simple stereo center cancellation.
3. On this server, use `/mnt/rpi/tmp` for temp files and caches and `/mnt/rpi/Music` or a nearby writable path for outputs.
4. If needed, ensure the system packages exist:
   - `sudo apt-get install -y python3-torch python3-torchaudio python3-antlr4`
5. Create a venv that reuses system packages:
   - `python3 -m venv --system-site-packages "/mnt/rpi/tmp/demucs-venv-sys"`
6. Install the lighter Python packages into that venv:
   - `TMPDIR="/mnt/rpi/tmp" PIP_CACHE_DIR="/mnt/rpi/tmp/pip-cache" "/mnt/rpi/tmp/demucs-venv-sys/bin/pip" install --no-deps demucs dora-search einops julius lameenc openunmix omegaconf retrying submitit treetable`
7. Run Demucs on CPU with vocals split out:
   - `TMPDIR="/mnt/rpi/tmp" XDG_CACHE_HOME="/mnt/rpi/tmp/.cache" "/mnt/rpi/tmp/demucs-venv-sys/bin/python" -m demucs -n htdemucs --two-stems vocals --mp3 --mp3-bitrate 320 --mp3-preset 2 -d cpu -o "<output-dir>" "<input-file>"`
8. The instrumental will be `no_vocals.mp3`; copy it to a clearly named final file near the source.
9. Verify the final file with `ffprobe` and share it if requested.

## Fallback

- if Demucs is unavailable, `ffmpeg` center cancellation can be used as a last resort, but call out that quality will often be worse and vocals may remain

## Rules

- never modify the original source file
- create a new output file with a clear suffix like `_karaoke_demucs.mp3`
- prefer CPU mode on this Raspberry Pi unless there is a known accelerator configured
- if root disk space is tight, clear only temporary caches you created and keep heavy caches under `/mnt/rpi/tmp`
- do not claim center cancellation is true stem separation


**Planning remote execution**

I need to use my laptop for CPU-heavy tasks and think I might use an SSH command, possibly with Tailscale. It should work after authentication. I need to figure out the target path and whether I should run a remote script. Maybe I should check if the laptop has dependencies I need. A memory search seems unnecessary, so I'll focus on running ffprobe locally first, then conduct remote checks via SSH.

bash

ls -l /home/sebas/downloads/mp3-share/please_do_not_lean.mp3 && ffprobe -v error -show_entries format=duration,bit_rate -of json /home/sebas/downloads/mp3-share/please_do_not_lean.mp3

        "duration": "240.143673",

**Checking demucs installation**

I need to check if I should run demucs remotely or if it needs to be installed. My first step is to look into whether it's available through pip or if I should set it up in a virtual environment. It’s possible that I might need to install it if it’s not already available in my current setup. So I should definitely double-check that either way!

ssh sebastians-macbook-pro-2 'python3 - <<'"'"'PY'"'"'
import importlib.util
mods=["demucs","torch","torchaudio"]
for m in mods:
    print(m, bool(importlib.util.find_spec(m)))
PY'

ssh sebastians-macbook-pro-2 'df -h ~ /tmp | sed -n "1,10p"'


demucs False
torch False
torchaudio False


Filesystem      Size    Used   Avail Capacity iused ifree %iused  Mounted on

/dev/disk3s5   460Gi   367Gi    31Gi    93%    7.6M  329M    2%   /System/Volumes/Data


**Setting up environment**

I’m considering installing some packages, and it might get heavy with pip. Using UV could be helpful too. I’m thinking about creating a virtual environment on my laptop, then transferring files using scp over Tailscale. Since I’m on a Raspberry Pi, I’d transfer to the laptop and then back again. For Python, I could set up a venv and install demucs with pip; the process might take a while, so I’ll use a longer timeout.

Heavy work now. Me do on laptop:
- copy source there
- make demucs venv if needed
- run separation on laptop CPU
- copy `no_vocals` back to `/home/sebas/downloads/mp3-share/please_do_not_lean_karaoke_demucs.mp3`

may take some minutes.

hecho.

usé la laptop para parte pesada y bajé resultado a carpeta correcta.

archivo final:
- `/home/sebas/downloads/mp3-share/karaoke/please_do_not_lean_karaoke_demucs.mp3`

sale también por nginx aquí:
- `http://100.116.176.16/mp3-share/karaoke/please_do_not_lean_karaoke_demucs.mp3`

detalle:
- método: Demucs real, `htdemucs`, separación de vocals
- resultado: instrumental `no_vocals`
- duración: `240.14s`
- bitrate: `320 kbps`

si quieres, yo también:
- lo abro en la laptop
- hago lo mismo con `cicatrices.mp3`


cambia la skill para que intente hacer la parte pesada en laptop de ahora en mas (sino fallback local)


**Considering skill documentation**

I’m thinking about editing the skill document, but I'm debating whether I should save it for memory—it's probably not necessary, but maybe it is for a more stable decision. I need to inspect the skill further; it might be enough as it is. There’s definitely a balance I need to find here. Let’s see if inspecting gives me more clarity on what to do next!

## Preferred Workflow

1. Confirm the source file exists and inspect it with `ffprobe`.
2. Prefer real stem separation with Demucs over simple stereo center cancellation.
3. On this server, use `/mnt/rpi/tmp` for temp files and caches and `/mnt/rpi/Music` or a nearby writable path for outputs.
4. If needed, ensure the system packages exist:
   - `sudo apt-get install -y python3-torch python3-torchaudio python3-antlr4`
5. Create a venv that reuses system packages:
   - `python3 -m venv --system-site-packages "/mnt/rpi/tmp/demucs-venv-sys"`
6. Install the lighter Python packages into that venv:
   - `TMPDIR="/mnt/rpi/tmp" PIP_CACHE_DIR="/mnt/rpi/tmp/pip-cache" "/mnt/rpi/tmp/demucs-venv-sys/bin/pip" install --no-deps demucs dora-search einops julius lameenc openunmix omegaconf retrying submitit treetable`
7. Run Demucs on CPU with vocals split out:
   - `TMPDIR="/mnt/rpi/tmp" XDG_CACHE_HOME="/mnt/rpi/tmp/.cache" "/mnt/rpi/tmp/demucs-venv-sys/bin/python" -m demucs -n htdemucs --two-stems vocals --mp3 --mp3-bitrate 320 --mp3-preset 2 -d cpu -o "<output-dir>" "<input-file>"`
8. The instrumental will be `no_vocals.mp3`; copy it to a clearly named final file near the source.
9. Verify the final file with `ffprobe` and share it if requested.

## Preferred Workflow

1. Confirm the source file exists and inspect it with `ffprobe`.
2. Prefer real stem separation with Demucs over simple stereo center cancellation.
3. **Default heavy work target is Sebas laptop** via Tailscale SSH host `sebastians-macbook-pro-2` when available.
4. Laptop-first flow:
   - copy source audio to `~/tmp/karaoke-share/` on the laptop
   - create/reuse venv at `~/.cache/demucs-venv`
   - install `demucs` there if missing
   - run Demucs on laptop CPU: `python -m demucs -n htdemucs --two-stems vocals --mp3 --mp3-bitrate 320 --mp3-preset 2 -d cpu -o "<output-dir>" "<input-file>"`
   - copy resulting `no_vocals.mp3` back to the original machine near the source, usually with suffix `_karaoke_demucs.mp3`
5. If laptop path is unavailable or fails, fall back to local Pi execution.
6. On local Pi fallback, use `/mnt/rpi/tmp` for temp files and caches and `/mnt/rpi/Music` or a nearby writable path for outputs.
7. If needed on local Pi, ensure the system packages exist:
   - `sudo apt-get install -y python3-torch python3-torchaudio python3-antlr4`
8. Create a local venv that reuses system packages:
   - `python3 -m venv --system-site-packages "/mnt/rpi/tmp/demucs-venv-sys"`
9. Install the lighter Python packages into that local venv:
   - `TMPDIR="/mnt/rpi/tmp" PIP_CACHE_DIR="/mnt/rpi/tmp/pip-cache" "/mnt/rpi/tmp/demucs-venv-sys/bin/pip" install --no-deps demucs dora-search einops julius lameenc openunmix omegaconf retrying submitit treetable`
10. Run local Demucs on CPU with vocals split out:
   - `TMPDIR="/mnt/rpi/tmp" XDG_CACHE_HOME="/mnt/rpi/tmp/.cache" "/mnt/rpi/tmp/demucs-venv-sys/bin/python" -m demucs -n htdemucs --two-stems vocals --mp3 --mp3-bitrate 320 --mp3-preset 2 -d cpu -o "<output-dir>" "<input-file>"`
11. The instrumental will be `no_vocals.mp3`; copy it to a clearly named final file near the source.
12. Verify the final file with `ffprobe` and share it if requested.

## Rules

- never modify the original source file
- create a new output file with a clear suffix like `_karaoke_demucs.mp3`
- prefer CPU mode on this Raspberry Pi unless there is a known accelerator configured
- if root disk space is tight, clear only temporary caches you created and keep heavy caches under `/mnt/rpi/tmp`
- do not claim center cancellation is true stem separation

## Rules

- never modify the original source file
- create a new output file with a clear suffix like `_karaoke_demucs.mp3`
- prefer Sebas laptop first for CPU-heavy separation work; if that fails, fall back local
- prefer CPU mode on this Raspberry Pi unless there is a known accelerator configured

- if root disk space is tight, clear only temporary caches you created and keep heavy caches under `/mnt/rpi/tmp`
- do not claim center cancellation is true stem separation

## Rules

- never modify the original source file
- create a new output file with a clear suffix like `_karaoke_demucs.mp3`
- prefer Sebas laptop first for CPU-heavy separation work; if that fails, fall back local
- prefer CPU mode on this Raspberry Pi unless there is a known accelerator configured
- when using laptop, bring final output back to the original source directory or its nearby `karaoke/` subdir
- if root disk space is tight, clear only temporary caches you created and keep heavy caches under `/mnt/rpi/tmp`
- do not claim center cancellation is true stem separation

## Rules

- never modify the original source file
- do not delete the original downloaded/reference track after making karaoke; keep it beside the derived output unless the user explicitly asks to remove it
- create a new output file with a clear suffix like `_karaoke_demucs.mp3`
- prefer Sebas laptop first for CPU-heavy separation work; if that fails, fall back local

Keep original reference track for karaoke jobs

When downloading or preparing source audio for karaoke generation, keep the original/reference track after creating the karaoke output. Do not delete it unless Sebas explicitly asks.

Summary: When downloading or preparing source audio for karaoke generation, keep the original/reference track after creating the karaoke output. Do not delete it unless Sebas explicitly as…


hecho.

anoté en skill:
- no borrar track original/referencia
- mantenerlo al lado del derivado salvo pedido explícito tuyo

también guardé memoria durable:
- `mem_96934fac02314ee2b5707504cd934815`

y tranqui:
- original de `stop this train` sigue ahí
- karaoke también sigue ahí

si quieres, te digo paths exactos.


deja todos los mp3 en root de mp3-share


find /home/sebas/downloads/mp3-share -type f -name '*.mp3' | sed -n '1,200p'


Mover mp3 al root de `mp3-share`.
yo haré:
- mover 3 mp3 anidados (`tmp-dl`, `karaoke`) al root
- dejar carpetas vacías quietas, salvo que quieras limpiar después

set -e
base='/home/sebas/downloads/mp3-share'
mv -n "$base/tmp-dl/stop_this_train_john_mayer.mp3" "$base/"
mv -n "$base/karaoke/please_do_not_lean_karaoke_demucs.mp3" "$base/"
mv -n "$base/karaoke/stop_this_train_john_mayer_karaoke_demucs.mp3" "$base/"
find "$base" -maxdepth 2 -type f -name '*.mp3' | sort | sed -n '1,200p'


hecho.

ahora todos los mp3 están en root de:
- `/home/sebas/downloads/mp3-share`

quedaron:
- `cicatrices.mp3`
- `please_do_not_lean.mp3`
- `please_do_not_lean_karaoke_demucs.mp3`
- `stop_this_train_john_mayer.mp3`
- `stop_this_train_john_mayer_karaoke_demucs.mp3`

si quieres, yo también limpio carpetas vacías `karaoke/` y `tmp-dl/`.
