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 | $0.00034 | $0.00770 |
| Opus 5 | $0.00017 | $0.00385 |
| Sonnet 5 | $0.00007 | $0.00154 |
| Haiku 4.5 | $0.00003 | $0.00077 |
Grade A, and why
agent-task 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.
How it starts
The opening of the file, as written. The whole thing — 60 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Agent Task
Use this skill when the user wants Codex to delegate a bounded implementation, research, or exploration task to an external agent.
Rules
- Codex remains the primary conversation and final reviewer.
- Create a task packet before launching any external agent.
- Keep the task narrow enough for one result file and one optional patch.
- Do not paste or log secrets, API keys, launcher contents, or provider environment variables.
- External agents should write outputs into the task folder.
- Do not claim the delegated task is complete until Codex has collected and reviewed result files.
Workflow
- Identify the workspace root and allowed paths.
- Choose
claude-code,reasonix, ormanual. - Run
New-AgentTask.ps1with the task, context, mode, target agent, and workspace root. - For implementation work where the external agent may edit repository files, create an isolated worktree before launch. See
Isolation For Implementation Tasks. - Launch the selected agent:
- Formal non-interactive worker:
Invoke-AgentTask.ps1after isolated worktree creation. It dispatches to Claude Code or Reasonix fromtarget_agent. - Claude Code direct compatibility runner:
Invoke-ClaudeCodeTask.ps1 - Reasonix direct compatibility runner:
Invoke-ReasonixTask.ps1 - Reasonix worker execution expects the
reasonixCLI to be on PATH, orREASONIX_COMMAND/-ReasonixCommandto point to the real CLI shim. - Close Reasonix Desktop before a CLI worker run. The runner preflights the Desktop process and translates CLI session-lock failures into a clear retry instruction.
- On Windows, the Reasonix runner denies
Bash(*), confines file writers to the isolated worktree withworkspace_root, restores any originalreasonix.toml, and leaves shell verification to Codex after collection. - Treat
reasonix-stdout.logandreasonix-stderr.logas redacted execution evidence. Canonicalagent-result.mdis cleaned and must start with# Agent Result.- Claude Code manual session:
Start-ClaudeTask.ps1 - Manual: give the task folder path to the user.
- Claude Code manual session:
- Wait for
agent-result.md,result.md, orpatch.diff. - Run
Collect-AgentResult.ps1; when an isolated worktree exists, the collector prints a git status review section. - Review the output before applying any patch or recommendation.
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.

agent-task is a skill published in the GitHub repository leviuszen/meaning-assurance (2 stars, last pushed 1mo ago), licensed Apache-2.0. It adds 34 tokens to every session and 770 once invoked, about $0.0002 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 2026-08-31.
