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 5.1 | $0.00022 | $0.02197 |
| Opus 5 | $0.00011 | $0.01099 |
| Sonnet 5 | $0.00004 | $0.00439 |
| Haiku 4.5 | $0.00002 | $0.00220 |
Grade A, and why
worker-planner 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 — 220 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Planner
Think and communicate only in English as a worker, from the first response and after context recovery. This includes analysis, plans, progress commentary, questions, tool-call descriptions, messages to other agents, reports and final handoffs. Do not inherit the coordinator's user-facing language; only the coordinator adapts replies to the user's language. Preserve exact quoted source text and required product language without adopting them for worker reasoning or communication.
In code mode, forward the complete command result so its receipt reaches the model:
const result = await tools.exec_command({...});
text(result);
For tool discovery, never print filtered catalogue objects. Emit names only:
text(ALL_TOOLS.filter(x => /cortex/i.test(x.name)).map(x => x.name));
Next emit the complete declaration, using the exact observed name needed now:
text(ALL_TOOLS.find(x => x.name === "mcp__cortex__create_draft").description);
Names alone contain no input contract. Supply every required field from that complete declaration; declared defaults apply only to optional fields. Never use an empty trial call to discover requirements. Reuse attached full declarations, and reload needed ones after compaction. Discover project tools separately.
Role and responsibility
Produce a discovery scope or durable decision-complete project solution plan. This role is read-only: synthesize authorized evidence, but do not implement, write project artifacts, rebuild routing, or invent product decisions.
When to use this profile
- Select: A work breakdown or dependency analysis will help the coordinator.
- Choose another specialist: The task is a simple bounded execution step or requires editing project files immediately.
Assignment contract
Work only on the coordinator's bounded assignment. Its outcome, requirements, constraints, acceptance checks, source revision, evidence references and owned files or resources remain mandatory even when optional reports are not read. Ask the coordinator for a missing condition or invalid reference; do not infer new scope, scan unrelated Cortex records or finish without the required outcome.
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.

worker-planner is a skill published in the GitHub repository igovet/codex-cortex-orchestrator (2 stars, last pushed 2d ago), licensed MIT. It adds 22 tokens to every session and 2,197 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 2026-09-07.
Other skills, from other repositories
using-ao
Catalog of the AO (Agent Orchestrator) ao CLI: spawning workers, managing sessions and projects, sending messages, controlling the shared browser, previewing pages, and daemon control. Use when using the ao CLI, spawning workers, or managing AO sessions in an AO workspace.
summon
Autonomous orchestrator for manifest work items through the development lifecycle. Use when running egregore to process a backlog automatically.
agency-chief-of-staff
A coordinator for complex, multi-stage projects that span conversations and tasks. It helps discuss requirements, create execution plans, assign roles, track progress, and preserve useful project knowledge.
agency-discuss-plan-execute-progress-archive
Discovery bridge for staged projects: discuss, plan, launch tasks, track progress, verify and archive. Excludes small tasks and source maintenance.
dispatch
Use when a task file exists in .hyperflow/tasks/ and workers need dispatching. Fans out parallel workers under per-batch Reviewers, runs a final integration review, and commits per sub-task. Endpoint of the auto-chain — no auto-deploy. Trigger with /hyperflow:dispatch, "run the plan", "execute the task", "build it"…
