What it does

Sage Init is an agent skill from SeJonJ/ChatForYou. Use at the start of a SAGE project to author both the shared project policy and the first machine-local capability profile. Block when the shared profile is already bootstrapped and route to sage-init-local.

Its SKILL.md is about 6.4k 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 Backend & APIs. The repository describes itself as: SpringBoot WebSocket & WebRTC Chatting.

When your agent uses it

  • Backend & APIs work in your project

Example prompts

  • “/sage-init”

Workflow steps

6 steps, taken from the step headings in SKILL.md.

  1. Read context first
  2. Interview (progressive conversation, one topic at a time)
  3. Shared policy and local capabilities
  4. Present for approval
  5. Handoff + asset generation (ask auto vs manual)
  6. Asset additions later (same loop)

What it can do on your machine

Read from SKILL.md and the folder at commit 2eaae14. 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

    Shell commands in SKILL.md call:

    • codex
    • claude

    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

Sage Init loads about 6.4k tokens when it runs. Until then it costs about 54 tokens; SKILL.md has 3,413 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~54
When it runs · the whole SKILL.md, loaded when a task matches
~6.4k

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); files beside SKILL.md are not scanned.

SKILL.md

Without a licence we can't republish the file, so here is its outline and opening line. It has 3,413 words (~6,437 tokens).

“Invoke as /sage-init (Claude) or $sage-init (Codex).”
