A workflow tool for turning a software objective into a persistent, trackable sequence of work run by command-line coding agents. It keeps the plan, progress, recovery information, and validation steps available across runs.

Use it to initialize, start, resume, inspect, validate, and summarize multi-step coding-agent workflows inside a project.

It helps long-running agent work continue after interruptions and makes the workflow auditable. It also separates workflow coordination from the project's own tools and execution rules.

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.

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	$0.00022	$0.00479
Opus 5.5	$0.00009	$0.00192
Sonnet 5.5	$0.00004	$0.00096
Haiku 4.5	$0.00002	$0.00048

Security

Grade A, and why

loopplane 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 1mo ago.

The scan reads SKILL.md. This mod also ships 7 executable files (examples/minimal_project/worker.py, examples/minimal_project/write_smoke_objective_reports.py, examples/minimal_project/write_smoke_plan.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.

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.

What it actually says

LoopPlane Skill

Use this skill when the user wants to turn a natural-language objective into a persistent, auditable, recoverable workflow.

LoopPlane owns agent workflow orchestration, not the project's execution backend. Keep machine, resource, launcher, and storage instructions in project shared context, runner configuration, or optional project skills. Never add site-specific command interception or resource policy to the generic runtime.

Read references/PROTOCOL.md first when installing, operating, debugging, or changing LoopPlane itself. Generated worker, recovery, validator, inspector, and summary runs already receive their role contract in the prompt; they must not reread the full protocol unless a concrete lifecycle or authority ambiguity requires it.

Required install-time CLI bootstrap:

loopplane skill install --target <project> is not complete until the required external CLI runners are found, configured, and doctored.
Before planning, starting, or resuming a provider-backed workflow, configure Codex runners with the stable command codex; LoopPlane resolves the current PATH or editor-extension binary at doctor and execution time. Find the Claude Code CLI path with command -v claude when Claude runners are used.
Configure the relevant runner(s) with loopplane configure-agent --project <project> --command codex for Codex or the discovered Claude command, then run loopplane doctor-agent --project <project> --runner <runner_id> or loopplane doctor-agent --project <project> --all.
If skill install, skill update, or doctor-agent reports *_waiting_config or runner_readiness: waiting_config, do not continue to plan, activate-plan, start, or resume; resolve CLI discovery, authentication, or runner configuration first.
Do not ask the user to manually locate Codex or Claude until you have tried safe PATH discovery and the doctor output still cannot identify a usable installed/authenticated CLI.

Common operations:

initialize a local workflow instance;
turn a user brief into an audited PLAN.md;
configure CLI agent runners;
start, pause, resume, or inspect the workflow;
open the dashboard;
create change requests.

Files

What ships with it

52 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.

loopplane is a skill published in the GitHub repository LJC-FVNR/LoopPlane (11 stars, last pushed 2mo ago), licensed Apache-2.0. It adds 22 tokens to every session and 479 once invoked, about $0.0001 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 2026-08-30.
