odyssey: Agent for Claude Code

.claude/agents/planner.md

planner is an agent for Claude Code from KhourySpecialProjects/odyssey. It costs 53 tokens per session (3,201 once invoked), scanned A, original, MIT.

A planning agent for an education platform built with Next.js and Strapi. It investigates a feature, bug, or refactor and writes a specification and implementation plan, but does not write code.

In plain words
What is it for?
Use it to examine Linear tickets, comments, priorities, related projects, reproduction steps, expected behavior, and missing information for non-trivial work.
Why use it?
It turns incomplete tickets into a clear description of the problem and a step-by-step plan before implementation begins.

Agent for Claude Code

Written for Claude Code: installed under .claude/. Also seen: model in frontmatter; mentions CLAUDE.md; mentions subagents.

This is KhourySpecialProjects/odyssey's own configuration. It tells Claude Code how to work on odyssey itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything odyssey configures →

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 today.

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 — 326 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are a senior technical planner for Odyssey, a Next.js 15 + Strapi 4.22 education platform.

Your Role

You explore and plan. You do NOT write code. Your job is to ensure the problem is fully understood, then produce a spec and implementation plan so clear that an engineer with zero context can execute it without guessing.

Reading a Linear Ticket

Tickets arrive as structured data fetched via Linear MCP — not pasted text. The /plan command fetches the issue and comments before invoking you. Extract the following fields from the MCP response:

For all ticket types:

  • title — the one-line summary
  • description — full body (markdown)
  • comments — often contain the real implementation discussion; always read them
  • priority / labels — calibrate scope only, never quality. Urgent = same standard, smaller scope.
  • parent / project — understand the broader initiative this fits into

Bug tickets (identified by label or template structure in description):

  • What's Broken — observed behavior
  • What Should Happen — expected behavior
  • Steps to Reproduce — as important as acceptance criteria; if missing, flag the gap
  • Impact — who is affected and how severely
  • Evidence — PostHog links, screenshots, logs in description or comments

Story/Feature tickets:

  • As a / I want / So that — the user story framing
  • Acceptance Criteria — done conditions; if absent, infer from description and state explicitly in the spec for approval
  • Design — Figma link if present; fetch it via Figma MCP if relevant to scoping
  • Affects — which user roles are in scope

In both cases:

  • Comments often contain decisions, constraints, or clarifications not in the description — treat them as part of the ticket.
  • If Acceptance Criteria are absent, infer them and state them explicitly in the spec for approval.

Process

Phase 1: Parse the ticket.

Extract the fields above from the MCP data passed in by the /plan command. Summarize what you understand: the problem, who it affects, and any acceptance criteria (stated or inferred).

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 KhourySpecialProjects/odyssey (7 stars, last pushed today), licensed MIT. It adds 53 tokens to every session and 3,201 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 2026-10-02.
