start-work

start-work is a skill for Claude Code, Codex from code-yeongyu/lazyclaudecode. It costs 63 tokens per session (1,823 once invoked), scanned A, original, MIT.

A work-execution guide for Codex that carries out an existing Prometheus plan and records progress and supporting evidence.

In plain words
What is it for?
Use it to start, continue, or resume a .omo/plans work plan, coordinate parallel coding tasks, and track what was done and why.
Why use it?
It helps keep planned coding work organized across separate worktrees and agent tasks, including when work needs to continue after a stop.

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.

Security

Grade A, and why

start-work 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 4d 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.

Claude Code Harness Tool Compatibility

This skill may include examples copied from the OpenCode or Codex harness. In Claude Code, do not call OpenCode/Codex-only tools such as task(...), call_omo_agent(...), spawn_agent(...), background_output(...), wait_agent(...), team_*(...), send_message(...), followup_task(...), or close_agent(...) literally. Translate those examples to Claude Code native tools:

OpenCode / Codex example Claude Code tool to use
task(subagent_type="explore", ...) / call_omo_agent(...) / spawn_agent(agent_type="explorer", ...) the Task tool (spawn a subagent of the matching type)
task(subagent_type="plan"/"oracle", ...) / spawn_agent(agent_type="plan"/"reviewer", ...) the Task tool with the planner/reviewer subagent, or the Skill tool
task(category="...", ...) the Task tool (general-purpose subagent) or run the work inline
background_output(...) / wait_agent(...) await the subagent's return value / the system completion notification
team_*(...) / send_message/followup_task/close_agent run multiple Task subagents and synthesize their results

When translating load_skills=[...], invoke the requested skills with the Skill tool or pass their names in the spawned subagent's prompt. If a code block below conflicts with this section, this section wins.

(superseded) Codex Harness Tool Compatibility

This skill ports the OpenCode /start-work flow onto Codex. Any OpenCode-only tool name in an inherited example must be translated to its Codex equivalent:

OpenCode example Codex tool to use
task(subagent_type="explore", ...) spawn_agent(agent_type="explorer", task_name="...", message="...")
task(subagent_type="librarian", ...) spawn_agent(agent_type="librarian", task_name="...", message="...")
task(subagent_type="plan", ...) spawn_agent(agent_type="plan", task_name="...", message="...")
task(subagent_type="oracle", ...) for final verification spawn_agent(agent_type="codex-ultrawork-reviewer", task_name="...", message="...")
task(category="...", ...) for implementation or QA spawn_agent(agent_type="worker", task_name="...", message="...")
background_output(task_id="...") wait_agent(...)
dispatchInternalPrompt(...) the Stop hook emits {"decision":"block","reason":"<prompt>"} automatically; see Continuation
team_*(...) spawn_agent + send_message + followup_task + wait_agent + close_agent

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.

start-work is a skill published in the GitHub repository code-yeongyu/lazyclaudecode (18 stars, last pushed 3mo ago), licensed MIT. It adds 63 tokens to every session and 1,823 once invoked, about $0.0003 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.
