What it does

Sage Plan Fast is an agent skill from SeJonJ/ChatForYou. Author and open a composite 00 Fast Plan for an explicitly enabled L2/L3 Fast Cycle.

Its SKILL.md is about 1.6k 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-plan-fast”

Workflow steps

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

  1. an explicit --lang ko|en on this skill's invocation,
  2. interface.language in sage/project-profile.local.yaml,
  3. ko.

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:

    • git

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

  • Network

    No URLs in SKILL.md. Its commands use git, which can reach the network depending on how they are called.

    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 Plan Fast loads about 1.6k tokens when it runs. Until then it costs about 25 tokens; SKILL.md has 860 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~25
When it runs · the whole SKILL.md, loaded when a task matches
~1.6k

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 860 words (~1,579 tokens).

“Invoke as /sage-plan-fast on Claude or $sage-plan-fast on Codex.”
