ultragoalDurable multi-goal workflow that persists plan/ledger artifacts under .omc/ultragoal and prints Claude /goal handoff text for the active session
Ultragoal is an agent skill from Yeachan-Heo/oh-my-claudecode. Durable multi-goal workflow that persists plan/ledger artifacts under .omc/ultragoal and prints Claude /goal handoff text for the active session
Its SKILL.md is about 1.7k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Agent Workflows. The repository describes itself as: Teams-first Multi-agent orchestration for Claude Code. The licence is MIT.
5 steps, taken from the first numbered list in SKILL.md.
Read from SKILL.md and the folder at commit 454bae0. It shows what the files ask for, not the result of running them.
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Ultragoal loads about 1.7k tokens when it runs. Until then it costs about 39 tokens; SKILL.md has 830 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

.claude/skills/ultragoal/SKILL.md (or your agent's skills folder).<Purpose>
Ultragoal breaks a brief into an ordered set of goals, records start/checkpoint/blocker/failure events in a durable append-only ledger, and tells the active Claude agent how to drive the Claude Code `/goal` slash command alongside the plan. It does not — and cannot — mutate Claude `/goal` state from the shell; it persists durable repo state and prints a model-facing handoff that the active agent must act on in-session.
</Purpose>
<Use_When>
/goal directive coordinated with the ledger so that a session restart does not lose progress
</Use_When><Do_Not_Use_When>
ralph instead/goal itself from the shell — that is not possible; omc ultragoal only writes artifacts and prints handoff textplan instead
</Do_Not_Use_When><Why_This_Exists>
Claude Code /goal is a session-scoped Stop hook: it blocks the session from stopping until a condition holds, and auto-clears on success. That is a great single-session execution primitive, but it loses state across sessions and does not by itself enforce a final review gate. omc ultragoal adds a durable plan, ledger, and gating layer so a long multi-step initiative can survive session restarts, fresh worktrees, and review iterations while still leveraging Claude /goal to keep the active agent focused.
</Why_This_Exists>
<How_To_Use>
Create a plan from a brief:
omc ultragoal create-goals --brief-file plan.mdOr with explicit stories:
omc ultragoal create-goals --brief "ship the migration" \
--goal "Schema::Add new columns" \
--goal "Backfill::Backfill rows in batches" \
--goal "Cutover::Drop old columns and switch reads"The default mode is aggregate (one Claude /goal covers the run).
Pass --claude-goal-mode per-story if you want each story to have its own /goal.
Multi-repo workspaces / parallel sessions: when several Claude sessions
in the same workspace need to run /ultragoal concurrently, pass either
--plan-id <stable-id> or --auto-plan-id so the plan is written to
.omc/ultragoal/plans/{planId}/ instead of the shared single-plan path.
Without that flag, two sessions creating goals would clobber each other.
--auto-plan-id derives {epochMs}-{slug} from the brief title. Then thread
the same --plan-id <id> through every subsequent subcommand in that session.
Use omc ultragoal list-plans to enumerate available planIds when needed.
Start (or resume) the next story:
omc ultragoal complete-goals [<goal-id>]With no goal id, this preserves the default behavior of resuming the active story or starting the first pending story. With a goal id, OMC targets exactly that named eligible story (a pending story may be started out of order); it never falls through to another story. An active different story, unknown id, completed or review-blocked story, or failed story without --retry-failed is rejected without state mutation. An in-progress named story is resumed without changing its attempt. This prints a model-facing handoff. The active Claude agent must read it and:
/goal for this session — in standalone Claude Code neither the
shell nor the agent can do it, so ask the user to type /goal <aggregate objective> and
wait. --claude-goal-json (below) reconciles the ledger only and does not satisfy the
PreToolUse /goal guard, which blocks tool calls until it observes an active /goal./goal state and call checkpoint.Checkpoint a story:
omc ultragoal checkpoint --goal-id G001-... --status complete \
--evidence "tests/files/PR evidence" \
--claude-goal-json '{"goal":{"objective":"...","status":"active"}}'For the final story, also pass --quality-gate-json containing
aiSlopCleaner, verification, and codeReview evidence (all clean).
If the final review is not clean, do NOT mark complete. Record blockers:
omc ultragoal record-review-blockers --goal-id G00X-... \
--title "Resolve final code-review blockers" \
--objective "Fix the listed review findings and rerun final gates" \
--evidence "<the review findings>" \
--claude-goal-json '{"goal":{"objective":"...","status":"active"}}'This appends a new blocker story and keeps the Claude /goal active.
Inspect state at any time:
omc ultragoal status</How_To_Use>
<Important_Limitations>
/goal state. omc ultragoal only persists durable artifacts and prints instructions that the active Claude agent reads and acts on in-session.--claude-goal-json are model-supplied proof of the active /goal state; OMC validates them for textual consistency with the plan's expected objective and ledger event, but it cannot independently observe Claude /goal state. They do not satisfy the PreToolUse /goal guard, which requires an actual active /goal — a host-injected snapshot or the native /goal the user set in-session./goal slash command is renamed or restructured, only the handoff wording needs to change; the reconciliation logic is name-agnostic.
</Important_Limitations>.omc-workspace marker at the parent directory so multiple sessions across sub-repos share one .omc/. Resolution order: OMC_STATE_DIR > .omc-workspace > git > cwd. See docs/REFERENCE.md.--plan-id to keep parallel ultragoal runs on separate ledgers.© Yeachan-Heo, MIT.

Ultragoal fits situations like: agent Workflows work in your project.
Run `npx skills add Yeachan-Heo/oh-my-claudecode --skill ultragoal -a claude-code`. Or copy the skill folder (skills/ultragoal in Yeachan-Heo/oh-my-claudecode) into .claude/skills/ultragoal in your project. Claude Code loads it when a task matches its description.
Run `npx skills add Yeachan-Heo/oh-my-claudecode --skill ultragoal -a codex`. Or copy the skill folder (skills/ultragoal in Yeachan-Heo/oh-my-claudecode) into .agents/skills/ultragoal in your project. Codex loads it when a task matches its description.
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add Yeachan-Heo/oh-my-claudecode --skill ultragoal -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/ultragoal, .gemini/skills/ultragoal, .github/skills/ultragoal and .opencode/skills/ultragoal in your project.
SKILL.md names no scripts, command-line tools or credentials: Ultragoal is instructions for the agent only.
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
Ultragoal is published under the MIT licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
About 1.7k tokens (SKILL.md is roughly 6.9k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
