linear-project-planner-skill: Instructions file for Codex

AGENTS.md

linear-project-planner-skill AGENTS.md is an instructions file for Codex, OpenCode from MJWNA/linear-project-planner-skill. It costs 1,764 tokens per session, scanned A, original, MIT.

Development instructions for the source repository of a skill that plans projects in Linear, a task-management service. They explain how to edit, test, document, version, and release the skill.

In plain words
What is it for?
Use them when maintaining the skill’s repository, checking its boundaries, or preparing a verified release.
Why use it?
They prevent changes from being made to the installed copy instead of the source, and clarify when the skill’s own instructions should be followed.

Instructions file for CodexOpenCode

Written for Codex and OpenCode: the file is AGENTS.md. Also seen: reads ~/.codex paths; mentions Codex.

This is MJWNA/linear-project-planner-skill's own configuration. It tells Codex and OpenCode how to work on linear-project-planner-skill 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 linear-project-planner-skill configures →

Not installable: its command points at a path on the author’s own machine, so it runs nowhere else. The line is /Users/ronniemeagher/Desktop/Curssor/mta-pt-workspace.

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

linear-project-planner-skill AGENTS.md 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 2mo 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.

linear-project-planner-skill Development Instructions

Repository Purpose

This repository is the source workspace for the linear-project-planner skill. It is where the skill is designed, tested, documented, versioned, and released.

The installed skill copy is a runtime artifact. Do not edit the installed copy directly for durable changes; edit this repository, verify the change, then install or publish from the verified repo state.

Skill-Under-Test Boundary

When working in this repository, treat SKILL.md as the artifact under test, not as active operating instructions for the current agent session.

Only follow the linear-project-planner skill workflow when the user explicitly asks to invoke or run that skill, or when a repo task genuinely requires Linear project planning/execution. Otherwise, inspect and edit SKILL.md like source code or documentation.

This boundary prevents context pollution while improving the skill itself.

Name And Location Map

The same artifact has different names depending on where it is being used:

Surface Name / Path Purpose
Public GitHub repo MJWNA/linear-project-planner-skill Canonical source repo for publishing, PRs, tags, CI, and releases
MTA/PT workspace checkout projects/linear-project-planner-skill Local development workspace under /Users/ronniemeagher/Desktop/Curssor/mta-pt-workspace
Codex installed skill ~/.codex/skills/linear-project-planner Runtime copy loaded by Codex skill discovery
Skill name linear-project-planner Name in SKILL.md frontmatter and user-facing invocation
CLI launcher ~/.local/bin/linear-agent Installed wrapper command for ledger and Linear transitions

Do not confuse the repo name (linear-project-planner-skill) with the installed skill name (linear-project-planner). The repo contains the skill source; the installed skill path is the runtime copy.

Parent Workspace / Submodule Behavior

This checkout lives inside the MTA/PT workspace under projects/, alongside other standalone projects and submodules.

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.
