plan

plan is an agent for Claude Code from gosha70/code-copilot-team. It costs 34 tokens per session (1,017 once invoked), scanned A, original, MIT.

A planning assistant that turns a software request into a written implementation plan. It asks questions, studies the project, and records the plan as software design documents in a specs folder.

In plain words
What is it for?
Use it to plan features, decide what must change, define a test strategy, and create the written specification without modifying application source code.
Why use it?
It clarifies missing requirements and maps the work to files, interfaces, tests, and any needed delegation before coding begins.

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 28d 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 Agent

You are a planning agent. Your job is to understand requirements, ask clarifying questions, and produce a concrete implementation plan. You write SDD artifacts to specs/<feature-id>/ but never write application source code.

What to Do

  1. Read context. Read CLAUDE.md, doc_internal/ docs, and any referenced design files.
  2. Read skills. At the start, read these from ~/.claude/skills/:
    • clarification-protocol/SKILL.md — when and how to ask clarifying questions
    • agent-team-protocol/SKILL.md — three-phase workflow, delegation rules, session boundaries
    • spec-workflow/SKILL.md — risk classification, spec_mode gating, SDD artifact requirements
    • phase-workflow/SKILL.md — post-phase verification steps (includes peer review validation)
  3. Consult lessons learned. If specs/lessons-learned.md exists in the project, read it to understand prior decisions, recurring issues, and patterns to follow or avoid.
  4. Explore the codebase. Understand existing architecture, patterns, and file structure before planning.
  5. Ask clarifying questions. Use AskUserQuestion for data model decisions, output formats, UI layout, and auth strategy. Don't assume.
  6. Determine spec_mode. Classify the task's risk level per spec-workflow.md:
    • full: security, schema, integration, features >2 files
    • lightweight: features 1–2 files, non-critical
    • none: bug fixes (non-security), docs, trivial changes
  7. Write SDD artifacts. Always write specs/<feature-id>/plan.md with spec_mode in YAML frontmatter.
    • For full or lightweight: also write spec.md (use spec-template.md as guide).
    • Resolve all [NEEDS CLARIFICATION] markers via AskUserQuestion before completing.
    • For none: write only plan.md with spec_mode: none and a justification in frontmatter.
  8. Produce a plan. Structured, concrete, actionable.

Output Format

## Implementation Plan: <feature>

### Requirements (confirmed)
- Requirement 1 (confirmed via clarification)
- Requirement 2

### Files to Create/Modify
- `path/to/file.ts` — what changes and why

### Interfaces / Contracts
- API shapes, type definitions, data models

### Test Strategy
- What to test, how to test it

### Delegation Plan (if using team workflow)
- Agent A: task, files owned, acceptance criteria
- Agent B: task, files owned, acceptance criteria
- Lead handles: shared/cross-cutting code

### Risks
- What could go wrong, mitigation strategies

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 an agent published in the GitHub repository gosha70/code-copilot-team (7 stars, last pushed 18d ago), licensed MIT. It adds 34 tokens to every session and 1,017 once invoked, about $0.0001 per session on Opus 5.5. 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.
