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 | $0.00024 | $0.01726 |
| Opus 5 | $0.00012 | $0.00863 |
| Sonnet 5 | $0.00005 | $0.00345 |
| Haiku 4.5 | $0.00002 | $0.00173 |
Grade A, and why
ulw-loop 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 2d 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 — 69 lines — stays where its author put it; the contents beside it link to each section on GitHub.
ulw-loop
Use this skill when the user asks for ulw-loop, ulw, durable goal execution, evidence-led work, manual QA, or checkpointed long-running delivery.
This skill is intentionally compact. The full workflow lives in references/full-workflow.md. Read only the sections needed for the current phase, then execute them exactly.
Required First Steps
- Open
references/full-workflow.md. - Read through Bootstrap (including its tier triage), Execution Loop, the Manual-QA channels table, and the Stop Rules before running any ULW command or recording evidence.
- If the task has code edits, tests, QA, or commit work, follow the full workflow's delegation and evidence rules. Tests alone never prove done.
Non-Negotiables
- Use the ulw-loop CLI state under
.omo/ulw-loop; do not hand-edit goal state. - Register goals up front (
omo ulw-loop create-goals, thencreate_goalfrom the printed handoff) and mirror every atomic step into the liveupdate_planchecklist: one ultra-granular step per action, exactly one in_progress, transitions marked the instant they happen. - After any compaction or context loss, re-read brief + goals + ledger FIRST plus
omo ulw-loop status --json, then resume; never re-plan from scratch. - If
omo ulw-loop create-goalssays the existing aggregate is already complete, start unrelated new work with a fresh--session-id <new-id>instead of steering or forcing the completed default state. Use--forceonly to intentionally overwrite completed evidence. - Every success criterion needs observable evidence from a real surface: a channel (terminal/TUI via the xterm.js web terminal, HTTP, browser, computer-use) or, for CLI- or data-shaped criteria, an auxiliary surface (CLI stdout, DB diff, parsed config dump).
- Evidence is bound to the tree it was captured at (
git rev-parse --short "HEAD^{tree}"); it goes stale only when tracked content changes — a rebase or amend that keeps the tree identical keeps it valid. When the tree differs, re-run at the current HEAD and re-record, never relabel or regenerate. Record only after cleanup receipts exist. - Delegate code edits, test writes, fixes, and QA execution to right-sized Codex subagents when the workflow requires it.
- Every
spawn_agentmessage starts withTASK:, then namesDELIVERABLE,SCOPE, andVERIFY; put role and specialty instructions insidemessage; usefork_turns: "none"(v1:fork_context: false) unless full history is truly required. - Plan and reviewer agents may run for a long time; spawn them in the background and keep doing independent root work. Between
wait_agentcalls, back off — double the timeout up to ~5 minutes — instead of spinning short cycles. - For work likely to exceed one wait cycle, require the child to send
WORKING: <task> - <current phase>before long reading, testing, or review passes, andBLOCKED: <reason>only when it cannot progress. - Track spawned agent names locally. Use
wait_agentfor mailbox signals, not proof of completion. A timeout only means no new mailbox update arrived. Treat a running child as alive. - While children run, surface the active subagent count, agent names, and latest
WORKING:phase. - Fallback only when the child is completed without the deliverable, ack-only after
followup_task, explicitlyBLOCKED:, or no longer running. Then record inconclusive and respawn a smallerfork_turns: "none"task with the missing deliverable. - Use
git-masterfor git-tracked edits: inspect recent and touched-path commit history, then commit each verified work unit atomically in the repository's observed language, scope, and message style with only that unit's files staged. Never carry verified units into a later omnibus commit.
What ships with it
3 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.
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.

ulw-loop is a skill published in the GitHub repository code-yeongyu/lazycodex (3,350 stars, last pushed 23d ago), licensed MIT. It adds 24 tokens to every session and 1,726 once invoked, about $0.0001 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 2026-08-30.
