What it does

Sage Plan is an agent skill from SeJonJ/ChatForYou. Plan the first half of a SAGE PDCA cycle (Phases 00–02) — verifies gate conditions, invokes the leader to author plan docs, and distributes file ownership before any implementation begins. Hands back an ownership map that /sage-team (03–06) picks up. Invoke when the user says /sage-plan (Claude) or $sage-plan (Codex), 기획, 설계 시작, 계획 세워, plan a feature, or wants to scope a change before implementation.

Its SKILL.md is about 3.2k 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

Says /sage-plan (Claude)
$sage-plan (Codex)
Wants to scope a change before implementation

Example prompts

“/sage-plan”

Requirements

Python 3

Workflow steps

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

Scope + planning interview
Invoke the leader
Verify plan doc exists
Report ownership map
State the phase flow (so the user knows what comes next)

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:
- python
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 Plan loads about 3.2k tokens when it runs. Until then it costs about 103 tokens; SKILL.md has 1,763 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~103
When it runs · the whole SKILL.md, loaded when a task matches: ~3.2k

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 1,763 words (~3,205 tokens).

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