A project-management interface for Plane, a tool used to track work items, cycles, and modules through its programming interface.

Listing or searching work items, cycles, and modules; finding items such as GP-42; creating items; pulling status into Markdown; and comparing local information with Plane.

It gives an agent a consistent way to read and update project status without manually navigating the Plane website.

Origin original No closer match found in the catalogue.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00054	$0.01122
Opus 5.5	$0.00022	$0.00449
Sonnet 5.5	$0.00011	$0.00224
Haiku 4.5	$0.00005	$0.00112

Security

Grade A, and why

plane scanned grade A 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 2mo ago.

The scan reads SKILL.md. This mod also ships 11 executable files (scripts/plane_api.py, scripts/plane_compare.py, scripts/plane_create.py, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

All Plane operations use Python scripts calling the REST API via curl.

How it starts

The opening of the file, as written. The whole thing — 88 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Plane.so Skill

Comprehensive interface to the Plane Cloud workspace ([your-workspace-slug], project Grand Plan).

Architecture: Direct API Scripts

All Plane operations use Python scripts calling the REST API via curl. No MCP server dependency — works in interactive and batch contexts.

Operation	Script
List items, cycles, modules	`plane_list.py items`, `plane_list.py cycles`, `plane_list.py modules`
List items in a module	`plane_list.py module-items "Pending Review"`
Filter by state/due date	`plane_list.py items --state todo,in_progress --due-within 7`
Create item (+ add to module)	`plane_create.py "Title" --module "Pending Review"`
Get item by identifier (GP-42)	`plane_lookup.py GP-42`
Search items by keyword	`plane_search.py "keyword"`
Pull Plane status → markdown	`plane_pull.py [--apply]`
Compare local vs Plane	`plane_compare.py [--diff-only] [--module slug]`

Gap Script Usage

All scripts require PLANE_API_KEY. On Mac, inject at call time:

# Lookup by identifier
PLANE_API_KEY=$(op item get "Plane API" --vault "Dev Secrets" --fields label="API Key" --reveal) \
    python3 .claude/skills/plane/scripts/plane_lookup.py GP-42

# Search
PLANE_API_KEY=$(op item get "Plane API" --vault "Dev Secrets" --fields label="API Key" --reveal) \
    python3 .claude/skills/plane/scripts/plane_search.py "authentication" --state todo

# Push: markdown -> Plane (dry-run by default, --apply for live)
python3 .claude/skills/plane/scripts/plane_sync.py          # dry-run
python3 .claude/skills/plane/scripts/plane_sync.py --apply   # live changes

# Pull: Plane -> markdown (dry-run by default, --apply writes with backup)
PLANE_API_KEY=$(op item get "Plane API" --vault "Dev Secrets" --fields label="API Key" --reveal) \
    python3 .claude/skills/plane/scripts/plane_pull.py           # dry-run
PLANE_API_KEY=$(op item get "Plane API" --vault "Dev Secrets" --fields label="API Key" --reveal) \
    python3 .claude/skills/plane/scripts/plane_pull.py --apply   # live (backs up to .plane-pull-backup/)

# Compare: side-by-side diff (read-only)
PLANE_API_KEY=$(op item get "Plane API" --vault "Dev Secrets" --fields label="API Key" --reveal) \
    python3 .claude/skills/plane/scripts/plane_compare.py              # full table
PLANE_API_KEY=$(op item get "Plane API" --vault "Dev Secrets" --fields label="API Key" --reveal) \
    python3 .claude/skills/plane/scripts/plane_compare.py --diff-only  # only mismatches
PLANE_API_KEY=$(op item get "Plane API" --vault "Dev Secrets" --fields label="API Key" --reveal) \
    python3 .claude/skills/plane/scripts/plane_compare.py --module infrastructure  # filter by module

What ships with it

15 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.

plane is a skill published in the GitHub repository jonathanmalkin/jules (67 stars, last pushed 5mo ago), licensed MIT. It adds 54 tokens to every session and 1,122 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
