At a glance

Index of trusted GJC SDK reference guides (broker, session CLI, embedding, app development).

  • Tasks that involve Embeddings
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md

What it does

Gjc SDK Guides is an agent skill from Yeachan-Heo/gajae-code. Index of trusted GJC SDK reference guides (broker, session CLI, embedding, app development). Advisory only: read these documents for background; there is no guide to execute and no workflow skill to run.

Its SKILL.md is about 280 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in AI & LLM Engineering, covering Embeddings. The licence is MIT.

When your agent uses it

  • Tasks that involve Embeddings

Example prompts

  • “/gjc-sdk-guides”

What it can do on your machine

Read from SKILL.md and the folder at commit 91fe978. 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

    No scripts in the folder and no shell commands in SKILL.md.

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

  • Network

    No URLs in SKILL.md.

    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

Gjc SDK Guides loads about 280 tokens when it runs. Until then it costs about 55 tokens; SKILL.md has 109 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~55
When it runs · the whole SKILL.md, loaded when a task matches
~280

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); files beside SKILL.md are not scanned.

GJC SDK guides (advisory)

Advisory index of trusted GJC SDK reference documents. These guides are reading material for background understanding; nothing in this skill is executable and no workflow skill is invoked.

  • docs/sdk.md — SDK overview: endpoint discovery, protocol, query and control surfaces, broker launch isolation, managed notification adapters.
  • docs/sdk-session-cli.md — the gjc sdk session command family: semantic verbs, raw hatch, lossless statuses, broker authority, and checkpoint gaps.
  • docs/sdk-embedding.md — embedding GJC in-process.
  • docs/sdk-app-guide.md — building applications on the SDK.

Advisory boundary

The references above are consulted as background, never executed. The plugin bundle keeps the four default workflow skills unchanged; this skill adds no workflow and performs no configuration or state mutation.
