A system for creating and carrying out durable plans with multiple goals, stored as files in the repository. Repository-native means the plan lives alongside the project code.

Use it to define several related goals, execute them, and track the resulting planning records.

It keeps larger work organized across sessions and preserves the plan inside the project.

ultragoal — Skill for Claude Code and Codex by Yeachan-Heo/oh-my-codex

About the project

oh-my-codex is a workflow layer for OpenAI Codex CLI that adds prompts, agent teams, skills, hooks, HUDs, and other runtime assistance while leaving Codex as the execution engine. It is for people who use Codex CLI and want structured workflows and additional help as tasks become larger. The catalogue entries are its skills, hooks, and MCP integrations for those Codex workflows.

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	$0.01087
Opus 5.5	$0.00009	$0.00435
Sonnet 5.5	$0.00004	$0.00217

Security

Grade A, and why

ultragoal 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.

Ultragoal Workflow

When to use

Use for ultragoal, create-goals, complete-goals, durable multi-goal planning, or sequential execution over Codex /goal. Read AGENTS.md#durable-runtime-invariants-canonical-ssot for state ownership and goal-tool boundaries.

Inputs and preconditions

Durable artifacts are .omx/ultragoal/brief.md, .omx/ultragoal/goals.json, and .omx/ultragoal/ledger.jsonl.
New plans use aggregate Codex goal mode by default: one stable pointer objective for the plan while OMX tracks individual stories. Use --codex-goal-mode per-story only when explicitly requested.
Do not call /goal clear from shell or this skill. After a completed run, the operator may clear the interactive Codex goal in the Codex UI before another same-thread run.

Operational steps: create

Run one command, then inspect the generated plan:

omx ultragoal create-goals --brief "<brief>"
omx ultragoal create-goals --brief-file <path>
cat <brief> | omx ultragoal create-goals --from-stdin
omx ultragoal create-goals --codex-goal-mode per-story --brief "<brief>"

If refinement is needed, use explicit supported steering rather than editing durable artifacts by hand.

Operational steps: execute

Repeat until omx ultragoal status reports all goals complete:

Run omx ultragoal complete-goals and read its handoff.
Call get_goal. Call create_goal with the printed payload only when no active Codex goal exists; otherwise continue the matching aggregate objective.
Complete one OMX story and audit its objective against real artifacts and verification evidence.

For intermediate aggregate stories, keep the Codex goal active and checkpoint:

omx ultragoal checkpoint --goal-id <id> --status complete --evidence "<evidence>" --codex-goal-json <fresh-get-goal-json-or-path>

For a blocked/failed story, use --status blocked|failed with evidence; resume failed work with omx ultragoal complete-goals --retry-failed.
On the final story, complete the final gate below before update_goal({status: "complete"}); then call get_goal again and checkpoint the fresh complete snapshot.

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.
