plan-protocol

plan-protocol is a skill for OpenCode from delorenj/ssbnk. It costs 14 tokens per session (1,776 once invoked), scanned A, a copy of plan-protocol, MIT.

A guide for creating and maintaining implementation plans with phases, numbered tasks, status markers, and source references.

In plain words
What is it for?
Use it when planning multi-step implementation work, updating plan progress, and connecting research to technical decisions.
Why use it?
It turns a broad development request into trackable work and records why important decisions were made.

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-protocol 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 4d 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.

Plan Protocol

Load this skill when creating or updating implementation plans.

TL;DR Checklist

When creating or updating a plan, ensure:

  • YAML frontmatter with status, phase, updated
  • ## Goal section (one sentence)
  • ## Context & Decisions table with citations (ref:delegation-id)
  • Phases with status markers: [COMPLETE], [IN PROGRESS], [PENDING]
  • Tasks with hierarchical numbering (1.1, 1.2, 2.1)
  • Only ONE task marked ← CURRENT
  • Citations for all research-based decisions

When to Use

  1. Starting a multi-step implementation
  2. After receiving a complex user request
  3. When tracking progress across phases
  4. After research that informs architectural decisions

When NOT to Use

  1. Simple one-off tasks → use built-in todos instead
  2. Pure research/exploration → use delegations only
  3. Quick fixes that don't need tracking
  4. Single-file changes with no dependencies

Plan Format

Use plan_save with this exact markdown format:

---
status: STATUS
phase: PHASE_NUMBER
updated: YYYY-MM-DD

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.
