What it does

Opt Library is an agent skill from gridaco/grida. Set up, download, verify, and seed the optional Grida Library developer corpus into local Supabase. Use when Library browse/search, Desktop reference picking, or agent Library tools need realistic local assets and Gemini embeddings; also use when changing the gridaco/grida consumer for gridaco/library developer-corpus releases.

Its SKILL.md is about 1.4k tokens, which your agent loads only when the skill is triggered. The skill folder holds 5 other files, including scripts (for example `agents/openai.yaml`, `scripts/seed.py` and `scripts/test_seed.py`).

It sits in AI & LLM Engineering, covering Embeddings. It works with Supabase. The licence is Apache-2.0.

When your agent uses it

  • Library browse/search
  • Desktop reference picking
  • Agent Library tools need realistic local assets and Gemini embeddings
  • Also use when changing the gridaco/grida consumer for gridaco/library developer-corpus releases

Example prompts

  • “/opt-library”

Requirements

  • Python 3

Workflow steps

7 steps, taken from the first numbered list in SKILL.md.

  1. downloads the pinned public prerelease into .tmp/opt-library/;
  2. verifies its pinned SHA-256, manifest, inventory, assets, and embedding
  3. obtains only the running local project's URL and service-role key from
  4. requires exact 127.0.0.1 API and database endpoints on the ports declared
  5. uploads content-addressed assets;
  6. transactionally upserts catalog rows and embeddings while suppressing only
  7. verifies database relationships and re-hashes a public local Storage read.

What it can do on your machine

Read from SKILL.md and the folder at commit 165496f. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Ships 2 files in scripts/ (Python), which the agent can run.

    Shell commands in SKILL.md call:

    • supabase
    • python

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    Links to these hosts (documentation or services it may open):

    • github.com
    • grida.co

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Opt Library loads about 1.4k tokens when it runs. Until then it costs about 85 tokens; SKILL.md has 639 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~85
When it runs · the whole SKILL.md, loaded when a task matches
~1.4k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); the scripts in this folder are not scanned.

description
Set up, download, verify, and seed the optional Grida Library developer corpus into local Supabase. Use when Library browse/search, Desktop reference picking, or agent Library tools need realistic local assets and Gemini embeddings; also use when changing the gridaco/grida consumer for gridaco/library developer-corpus releases.

Optional Library

opt-library is the setup and seeding skill for Grida's optional local Library service fixture. Use it to add a realistic corpus to an already-running local Grida stack. Keep it separate from the canonical migrations and base seed.

Why it is optional

The standard local database is complete without Library content. Its base seed creates only the categories required by ordinary development; an empty public corpus is valid.

The developer corpus is an additional product-development fixture: the current Home prerelease contains 631 images and is about 137 MiB compressed. Making it part of supabase db reset would impose download, storage, and reset costs on every contributor, including those not working on Library discovery. A reset therefore removes this optional data; rerun this skill when it is needed.

Seeding does not call an AI provider. The approved archive already contains the matching image and text representations. Runtime semantic queries still need Grida's configured query-embedding provider; cold browse works without it.

Repository topology

The Library deliberately spans two repositories:

  • gridaco/grida owns the data plane: Supabase schema and migration history, the public library storage bucket, product retrieval surfaces, and this local importer.
  • gridaco/library owns content operations: curation, batch producers, enrichment, and bounded developer corpus releases.

Do not move schema ownership or production credentials into the operations repository. Do not turn this importer into a production connector. The handoff between repositories is the versioned, sanitized archive contract.

Read the canonical Grida Library working-group document before changing this boundary. The operations-side archive contract is documented in fixture_release/README.md. The product surfaces are the Library and its licensing page.

Seed local Supabase

GRIDA-SEC-009 — local-destination boundary. seed accepts only the exact 127.0.0.1 API and database ports declared by this checkout's supabase/config.toml. It rejects localhost, IPv6 and alternate loopback hosts, remote/lookalike hosts, wrong ports or URL shapes, and all caller-provided destination URLs and keys before downloading or writing. Local service-role HTTP requests bypass system proxies and reject redirects; direct SQL strips inherited libpq PG* connection overrides.

Run from the gridaco/grida repository root:

sh
supabase start
python .agents/skills/opt-library/scripts/seed.py seed

Use the normal local Supabase prerequisites plus Python 3.12 and psql.

The command:

  1. downloads the pinned public prerelease into .tmp/opt-library/;
  2. verifies its pinned SHA-256, manifest, inventory, assets, and embedding contract before writing;
  3. obtains only the running local project's URL and service-role key from supabase status;
  4. requires exact 127.0.0.1 API and database endpoints on the ports declared by this checkout's supabase/config.toml;
  5. uploads content-addressed assets;
  6. transactionally upserts catalog rows and embeddings while suppressing only the redundant enrichment-enqueue trigger;
  7. verifies database relationships and re-hashes a public local Storage read.

It is idempotent by content hash. Use --limit for a quick smoke seed:

sh
python .agents/skills/opt-library/scripts/seed.py seed --limit 12

Inspect or prefetch the release without touching the database:

sh
python .agents/skills/opt-library/scripts/seed.py download
python .agents/skills/opt-library/scripts/seed.py verify

Pass --archive /path/to/archive.zip to verify or seed a maintainer-built archive. Treat that as an explicit local override; the default release remains pinned and must never silently follow latest.

Safety and maintenance

  • Keep this workflow opt-in. Never add the corpus to supabase/seed.sql or supabase/config.toml storage seeding.
  • Before changing Library migrations, schemas, RLS, grants, or the canonical base seed, load the database skill. Ordinary corpus download and local seeding remain in this skill.
  • Never read a production Supabase environment or accept a destination URL/key on the command line. The importer must discover the local stack itself and reject anything except the exact configured 127.0.0.1 endpoints.
  • Verify the complete archive before the first database or storage write.
  • Preserve content-derived identity. Store new assets at <sha256>.<extension> and use the local Storage object ID as catalog identity.
  • Preserve archive license values verbatim. Do not infer a broader license.
  • Run supabase db reset --local before database-test suites that expect the canonical empty corpus. The reset intentionally removes this optional seed.
  • When the archive format, representation model, or pinned release changes, update the validator and constants together, then verify both a smoke seed and the full corpus.
