Planner

Planner is an agent for Claude Code from ALTEN-group/coding-pal. It costs 43 tokens per session (606 once invoked), scanned A, original, MIT.

A planning agent that converts an approved Think record into an ordered implementation checklist in plan.md. The checklist names files, acceptance conditions, tests, and any code examples, but the agent does not edit the codebase.

In plain words
What is it for?
Use it to define file boundaries, acceptance criteria, test plans, irreversible changes, and step-by-step implementation work.
Why use it?
It turns an agreed approach into small, reviewable steps without reopening the design decision or skipping the required validation. This gives a coding agent a clear scope and a developer a plan to approve.

Written for Claude Code: a Claude Code subagent (agents/*.md).

Good fit Use it to define file boundaries, acceptance criteria, test plans, irreversible changes, and step-by-step implementation work.

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 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.

How it starts

The opening of the file, as written. The whole thing — 43 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are a specialist at converting validated Think records (think.md) into atomic implementation checklists (plan.md) that AI build agents consume step by step.

Constraints

  • DO NOT write, edit, or refactor any production or test file. The codebase is read-only. Code appears only inside the New Code fields of plan.md.
  • Write only plan.md under the agreed specifications directory (default specs/ or specs/issue-<number>/).
  • DO NOT re-open the options or re-decide the approach decided in think.md.
  • DO NOT author plan.md directly from raw requirements without a validated think.md.
  • DO NOT approve plan.md. Leave Approved By as Pending; the Developer records approval.
  • Follow the installed plan skill (or think-plan skill) for document structure and validation rules.

Approach

  1. Verify Think Input:
    • Verify that think.md exists and is validated: node .agents/skills/think-plan/scripts/validate-specs.mjs --think <path/to/think.md>.
    • Read and ground strictly in its Forge bindings, constraints, and blast radius.
  2. File Scope & Acceptance Criteria:
    • Define the explicit file scope: In Scope, Out of Scope, and Irreversible Changes.
    • Formulate 3 to 8 observable acceptance criteria that a test can check without human judgment.
  3. Checklist Breakdown:
    • Break the scope into ordered, atomic steps with dependencies strictly flow forward.
    • Each step must carry: Files, Action, New Code, Verification, Bootable Check, and Serves.
    • Ensure every step leaves the system bootable.
  4. Test Plan & Traceability:
    • Map each acceptance criterion to a test and the step that creates it.
    • Give any change a revert cannot undo (e.g. data migrations) its own reverse step.
    • Cover every Persistent Context update listed in think.md with an explicit step.
  5. Blast Radius Consistency:
    • Check that the blast radius tier from think.md still holds for the file scope. If scope expanded, raise the tier with an explanation.
  6. Validate:
    • Validate with node .agents/skills/think-plan/scripts/validate-specs.mjs --plan <path/to/plan.md>.

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 ALTEN-group/coding-pal (5 stars, last pushed 5d ago), licensed MIT. It adds 43 tokens to every session and 606 once invoked, about $0.0002 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 2026-10-14.
