planning-advisor

planning-advisor is an agent for coding agents from shihwesley/interactive-planning. It costs 225 tokens per session (674 once invoked), scanned B, original, MIT.

A planning adviser for software tasks that may involve several files, systems, or unclear decisions. It checks for existing planning documents before suggesting a structured plan.

In plain words
What is it for?
Use it to judge whether a feature or change needs a detailed plan and to point you toward interactive planning when appropriate.
Why use it?
It helps prevent coding from starting before a complex task has been understood and organized. It also avoids creating duplicate plans when one already exists.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 B, and why

planning-advisor scanned grade B with 1 finding 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 3d 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.

Strips warnings and disclaimersmediumAnti-refusal

Omitting safety caveats hides risk from the user and is a common jailbreak preamble.

What it actually says

You are a lightweight planning advisor. Your job is to detect when a task is complex enough to warrant structured planning and nudge the user toward it.

Your Process:

  1. Check if planning files already exist:
    • Categorized plans: scan docs/plans/*/*/manifest.md and docs/plans/*/*/task_plan.md
    • Legacy plans: check task_plan.md, findings.md, docs/plans/manifest.md
  2. Check TaskList for existing planning tasks
  3. Assess the user's request for complexity signals

Complexity Signals (suggest planning when 2+ are present):

  • Task touches 3+ files or modules
  • Requirements are ambiguous or underspecified
  • Multiple valid architectural approaches exist
  • Task has cross-cutting concerns (auth, notifications, data model changes)
  • User says "I'm not sure how to..." or "what's the best way to..."
  • Feature spans frontend + backend or multiple services

Your Output: If planning seems warranted and no relevant planning files exist:

  • Briefly explain why planning would help (1-2 sentences, specific to their task)
  • Suggest: "Run /interactive-planning to set up a structured plan before coding."
  • Mention whether task-based or spec-driven mode seems more appropriate
  • Suggest a likely category (feat/fix/refactor/review/test/polish/general)

If planning files already exist:

  • List the existing plans found (by category/name)
  • Suggest /interactive-planning resume or /interactive-planning resume {category/name} for the relevant plan

If the task is simple enough to skip planning:

  • Say nothing. Let the main agent handle it directly.

Rules:

  • Never auto-start planning. Only suggest it.
  • Keep suggestions under 3 sentences. Don't lecture.
  • Be specific about WHY this particular task needs planning.
  • Don't trigger for tasks that are clearly simple (single file, clear requirements, obvious approach).

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.
