plan

plan is a skill for Claude Code from xWael9/ClaudeBoss. It costs 54 tokens per session (466 once invoked), scanned A, original, MIT.

A planning workflow that sends architecture and design questions to a dedicated planning assistant before coding begins. It is intended for deciding what should change, under which constraints, and with which trade-offs.

In plain words
What is it for?
Use it when a task needs scoping or a plan review, especially before implementing the plan yourself or handing it to another coding workflow.
Why use it?
It gives non-trivial work a design review before implementation, helping expose missing edge cases, migration steps, and rollback needs.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

plan scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 5d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

ClaudeBoss — Plan Mode

Opencode ships a dedicated plan primary agent, separate from build. Use it when the task is "figure out the right approach" rather than "write the code" -- it's a distinct pass from /claudeboss:team and /claudeboss:boss, meant to run before either of them on non-trivial work.

Prerequisites

claudeboss install must have succeeded at least once on this machine.

Workflow

  1. Delegate the planning question, not the implementation:

    claudeboss run plan "<the design question: what needs to change, what constraints apply, what are the tradeoffs>"
    

    claudeboss run plan automatically routes to opencode's plan agent (not build) and a general-purpose free model.

  2. Review the plan like you'd review a design doc. Does it account for the actual codebase's conventions and constraints (you may need to check the real code yourself -- the free model has no memory of this specific project beyond what you told it)? Is it missing an edge case, a migration step, a rollback path?

  3. Hand off. Once the plan is sound, either:

    • implement it yourself,
    • delegate implementation to /claudeboss:team (you review + finish), or
    • delegate to /claudeboss:boss (you manage, opencode's build agent implements, you approve before deploy).

    Tell the user which handoff you're using and why.

  4. If the plan is weak (vague, ignores a stated constraint, unworkable), don't pass it downstream -- refine the prompt and re-run, or just write the plan yourself and say so. A bad plan compounds into worse code if it flows straight into /claudeboss:boss.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

plan is a skill published in the GitHub repository xWael9/ClaudeBoss (2 stars, last pushed 2mo ago), licensed MIT. It adds 54 tokens to every session and 466 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
