cortex-control

An internal control layer for a specific Cortex workflow version. Cortex is the host’s orchestration system for coordinating agent tasks, workers, reports, and project knowledge.

In plain words
What is it for?
Use it only after the Cortex orchestrator has been explicitly activated, to control coordinator and assigned-worker tasks.
Why use it?
It ensures that this specialized workflow follows its activation, communication, evidence, and coordination rules.

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

cortex-control 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 — 57 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Cortex Control Activation Kernel

This companion is host-supplied only after explicit cortex:orchestrator selection. Do not select it for ordinary work or fetch it through a tool. All worker communication, reports, ledger prose, and durable tool-authored strings are English; coordinator-facing communication follows the latest meaningful user language. The active MCP registry is authoritative for the semantic call contract.

Mode boundary

The coordinator kernel below applies only to coordinator mode after direct user route selection. A server-issued assignment_worker native child is a separate mode: it does not activate or reopen the coordinator route, and it cannot anchor tasks, govern, ask users, delegate, dispatch, or close. Its first semantic action is assignment-evidence consumption from the exact server-rendered dispatch brief. Only after the server confirms that evidence may it perform assigned work and publish its owned outcome.

Pre-anchor protocol

Task anchoring precedes every task-scoped semantic operation. This includes clarification holds and questions, plan or approval holds, steering, governance, knowledge routing, delegation, worker dispatch, and closure preparation. A clarification needed before planning is opened and presented after the task anchor and before planner dispatch; it is a hold on the anchored task, not an alternative to opening it. Before the anchor, allow only complete contract composition, the single task-opening attempt, and read-only reconciliation of that same attempt after explicitly ambiguous transport.

For project-facing work, the first project execution action is exactly one task-opening operation from the live advertised schema. Compose the complete outcome contract, make that opening call, and require its successful command receipt and task anchor before knowledge routing, project reads, adaptation, governance, delegation, worker dispatch, or any other project execution.

Prose activation acknowledgement is not evidence. Shell or repository inspection before the anchor is a route violation. If transport is ambiguous, reconcile the same opening attempt read-only; never create a second task. If no anchor can be established, stop rather than starting degraded work.

Changes

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.

cortex-control is a skill published in the GitHub repository igovet/codex-cortex-orchestrator (1 stars, last pushed 2d ago), licensed MIT. It adds 27 tokens to every session and 572 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 2026-08-31.
