Actual Computer Setup Skill

Sets up actual.inc (Actual Computer) as a Loki inference
provider. Actual turns the user's own hardware into a private inference cluster
and exposes an OpenAI-compatible API two ways: a hosted end-to-end-encrypted
relay at https://api.actual.inc (authenticated with an ac_ key), and a local
on-device daemon at http://127.0.0.1:8080 (no auth on loopback). This skill
does not install the Actual daemon for the user — device authorization requires
a human in a browser.

When to Use

• User wants to add actual.inc as an inference provider (cloud relay or local).
• User has an ac_ key and wants Loki routed through their Actual cluster.
• User wants fully-local, on-device inference via the Actual daemon.
• Troubleshooting: Actual requests failing with cryptic 400s or empty streams.

Prerequisites

• Loki has first-class actual provider support (provider id actual,
  aliases actual-computer, actualcomputer, aci). Do NOT configure Actual
  as a custom_providers / providers.actual.* entry on current Loki — the
  built-in provider owns the name and handles base-url normalization, the
  Responses transport, and local no-auth automatically.
• Relay mode: an Actual account and an ac_ inference key from
  https://actual.inc/user/keys.
• Local mode: the user has installed the daemon
  (curl -fsSL "https://actual.inc/install" | bash) and completed device
  authorization by running actual once and opening the printed
  https://actual.inc/device?code=... URL in a browser. Relay that URL to the
  user and WAIT — never invent an email or authorize on their behalf. Codes
  expire in 5 minutes; re-run actual for a fresh one.

How to Run

Relay / API mode

1. Put the key in .env (secrets only — never config.yaml):
   append ACTUAL_API_KEY=ac_... to ~/.loki/.env.
2. Verify the key and discover models with terminal:

   curl -s https://api.actual.inc/v1/models -H "Authorization: Bearer $ACTUAL_API_KEY"

3. Select provider + model:

   loki config set model.provider actual
   loki config set model.default "MODEL_ID_FROM_DISCOVERY"

4. Verify end-to-end:

   loki chat -Q -q "Reply with exactly: ACTUAL_OK" --provider actual -m MODEL_ID

Local mode

1. Human has installed + authorized the daemon (see Prerequisites).
2. Download and load a model (scriptable once authorized):

   actual models search "qwen2.5 0.5b instruct gguf" --limit 8 --no-prompt
   # Downloads REQUIRE an explicit quantization (409 ambiguous_model_download otherwise):
   actual models download "Qwen/Qwen2.5-0.5B-Instruct-GGUF/Q4_K_M"
   actual models list        # note the INSTALLED name (differs from download id)
   actual models load "qwen2.5-0.5b-instruct-q4_k_m"   # load by installed name

3. Point Loki at the daemon. ACTUAL_BASE_URL with a loopback host flips the
   built-in provider into local no-auth mode automatically — no key needed:
   append ACTUAL_BASE_URL=http://127.0.0.1:8080 to ~/.loki/.env, then:

   loki config set model.provider actual
   loki config set model.default "INSTALLED_MODEL_NAME"

4. Verify (reduced toolset — see context-window pitfall below):

   loki chat -Q -q "Reply with exactly: LOCAL_OK" --provider actual -m INSTALLED_NAME -t file,web

Quick Reference

Pitfalls

1. reasoning_effort trap (handled by Loki since the first-class provider).
   Actual's SGLang/vLLM backends accept only none/low/medium/high/max;
   xhigh/ultra used to fail with a cryptic
   Expecting value: line 1 column 1 (char 0) (a wrapped HTTP 400). The
   built-in provider clamps xhigh→high and ultra→max on the wire. If a
   request still 400s this way on an old Loki, set a per-model cap:
   agent.reasoning_overrides.<model>: high in config.yaml.
2. Context-window overflow on small local models. Loki' default toolset
   is ~26k tokens of schemas plus a ~9k-token system prompt. A model loaded
   with a 32k context overflows before the first turn, and llama.cpp-family
   servers emit a bare data: [DONE] — Loki reports
   Provider returned an empty stream with no finish_reason. This is NOT an
   SSE bug. Fixes: restrict tools (-t file,web), load the model with a
   larger n_ctx, or pick a >=64k-context model for the full toolset.
   Upstream tracking: #51448 (do not file new issues; add evidence there).
   Related but distinct: #65631 (HTTP-200 SSE carrying a 400), #56516
   (reasoning-only streams).
3. Download ids vs installed names. actual models download takes
   repo/QUANT and 409s without an explicit quantization;
   actual models load takes the INSTALLED name from actual models list.
4. Reasoning models returning empty content. GLM/Qwen reasoning variants
   emit thinking in a separate reasoning field and can burn a small
   max_tokens entirely on reasoning. Give generous max_tokens before
   assuming failure.
5. Do not create a custom provider named actual. Older setup guides
   (pre first-class support) wrote providers.actual.* config blocks. On
   current Loki the built-in provider wins the name; stale custom blocks
   are ignored or conflict. Remove them and use the env vars + model.provider
   flow above.

Verification

# Relay:
loki chat -Q -q "Reply with exactly: ACTUAL_OK" --provider actual -m MODEL
# Local (small model — reduced toolset):
loki chat -Q -q "Reply with exactly: LOCAL_OK" --provider actual -m MODEL -t file,web
# Provider status (local no-auth shows key_source=local-offline):
loki status
