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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.01764 | $0.01764 |
| Opus 5 | $0.00882 | $0.00882 |
| Sonnet 5 | $0.00353 | $0.00353 |
| Haiku 4.5 | $0.00176 | $0.00176 |
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 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 — 173 lines — stays where its author put it; the contents beside it link to each section on GitHub.
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.

linear-project-planner-skill AGENTS.md is an instructions file published in the GitHub repository MJWNA/linear-project-planner-skill (5 stars, last pushed 3mo ago), licensed MIT. It adds 1,764 tokens to every session, about $0.0088 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 2026-08-31.
