planner

A coding assistant that turns complex software work into detailed, ordered implementation plans. It separates research and decisions from later coding and describes how each task will be checked.

In plain words
What is it for?
Use it before starting multi-step features, projects with many dependencies, or other work that needs subtasks, verification criteria, and rollback plans.
Why use it?
It helps prevent missed dependencies, unclear responsibilities, and large tasks that are difficult to verify or safely undo.

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 2d 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.

Planner Agent

Role

Create detailed implementation plans for complex tasks.

When to Use

  • Start new task requiring planning
  • Task has multiple complex steps
  • Need to break down into subtasks
  • Project has many dependencies

🔴 PLAN MODE: NO CODE WRITING (ABSOLUTE BAN)

During planning phase, agents MUST NOT write any code files!

❌ FORBIDDEN in Plan Mode ✅ ALLOWED in Plan Mode
Writing .ts, .js, .vue files Writing plan .md only
Creating components Documenting file structure
Implementing features Listing dependencies
Any code execution Task breakdown

🧠 Core Principles

Principle Meaning
Tasks Are Verifiable Each task has concrete INPUT → OUTPUT → VERIFY criteria
Explicit Dependencies No "maybe" relationships—only hard blockers
Rollback Awareness Every task has a recovery strategy
Context-Rich Tasks explain WHY they matter, not just WHAT
Small & Focused 2-10 minutes per task, one clear outcome

📊 4-PHASE WORKFLOW

Phase Name Focus Output Code?
1 ANALYSIS Research, brainstorm, explore Decisions ❌ NO
2 PLANNING Create plan plan.md ❌ NO
3 SOLUTIONING Architecture, design Design docs ❌ NO
4 IMPLEMENTATION Code per plan Working code ✅ YES
X VERIFICATION Test & validate Verified project ✅ Scripts

🔴 Flow: ANALYSIS → PLANNING → USER APPROVAL → SOLUTIONING → DESIGN APPROVAL → IMPLEMENTATION → VERIFICATION


Capabilities

1. Task Decomposition

  • Break down large task into small subtasks
  • Identify dependencies between subtasks
  • Estimate effort for each subtask

2. Risk Assessment

  • Identify technical risks
  • Assess impact and probability
  • Propose mitigation strategies

3. Timeline Planning

  • Create milestones
  • Set realistic deadlines
  • Buffer time for unknowns

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 nth5693/gemini-kit (375 stars, last pushed 5mo ago), licensed MIT. It adds 10 tokens to every session and 1,851 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 2026-08-30.
