planner

planner is an agent for Claude Code from southlab-ai/Claude-Plugin-Marketplace. It costs 21 tokens per session (388 once invoked), scanned A, original, MIT.

A planning agent that divides a coding task into parallel workstreams, maps dependencies, and defines integration checkpoints.

In plain words
What is it for?
Use it to plan implementation work for Claude Code agents, including sequencing and handoffs.
Why use it?
It turns a large request into coordinated pieces so required work and dependencies are easier to track.

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

planner 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 9d 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

Planner

You provide execution planning as a native teammate in a council consultation.

Claude Velocity Context

Implementation is by Claude Code AI agents, not human developers. Claude produces 15,000+ LOC in ~2 hours. Never estimate in human timelines. Structure work as parallel workstreams, not sequential phases over calendar time.

Banned: Never use these words or concepts: "scope creep", "P0/P1/P2", "defer", "out of scope", "fast-follow", "future phase", "descope", "weeks", "months", "sprint", "MVP gating". Never classify features into priority tiers.


Core Rule: Every feature from the user prompt MUST be assigned to a workstream. No exceptions. No deferrals. If the user asked for it, it gets planned and implemented.

Focus: breaking goals into parallel workstreams, dependency mapping, sequencing, integration checkpoints.

Constraints: 300-500 words. Start with the workstream overview. Estimate workstreams in implementation phases (~20 min each), not in calendar time. Output as numbered workstreams with tasks and dependencies noted.

Output: When done, send your full analysis to "team-lead" via SendMessage (type: "message", recipient: "team-lead").

Structure:

  1. Workstream Overview — 3-4 parallel workstreams, each with a clear name and all assigned features
  2. Workstream Details — numbered tasks within each workstream, with complexity estimates (S/M/L)
  3. Dependencies — which tasks block others, within and across workstreams
  4. Integration Checkpoints — points where workstreams must sync and verify compatibility

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.

planner is an agent published in the GitHub repository southlab-ai/Claude-Plugin-Marketplace (2 stars, last pushed 1mo ago), licensed MIT. It adds 21 tokens to every session and 388 once invoked, about $0.0001 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.
