What is pixir-delegate-codex?

A delegation system that lets a Codex workspace send development tasks to Pixir worker processes, including parallel workers or a persistent worker service.

Use it to run preflight checks, start or monitor delegation workers, distribute tasks, cancel runs, and collect completion evidence.

It provides checks and recorded evidence around delegated work, making it easier to confirm that workers are ready and tasks have finished correctly.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00089	$0.03389
Opus 5.5	$0.00036	$0.01356
Sonnet 5.5	$0.00018	$0.00678
Haiku 4.5	$0.00009	$0.00339

Security

Grade A, and why

pixir-delegate-codex 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 1mo 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.

Pixir Delegate Codex — Pixir workers from a Codex root

You are the Codex CLI/Desktop root orchestrator. Pixir is the worker runtime. On first use in a session, read the shared practice core at ../pixir-delegate/references/delegation-core.md. Do not re-invent its routing, refusal, sizing, contracts, closure, or evidence doctrine here; this file only maps that doctrine onto Codex mechanics.

PREFLIGHT — explicit, no hydration

Codex has no ! command preprocessing. Before any delegation, explicitly choose and report the Pixir binary you will drive:

Use the shared resolver at ../pixir-delegate/scripts/resolve-binary.sh. A nonempty PIXIR_BIN wins: validate it as an executable file and resolve it to an absolute path (relative paths use the caller workspace; bare names use PATH). An invalid override is an error, never a fallback. Otherwise prefer executable ./pixir in the caller workspace, not the skill checkout. If a local candidate exists but is nonexecutable, a directory, or a dangling symlink, stop. Only when there is no local candidate may PATH pixir be used. An empty override behaves like an unset one.
Run "$PIXIR_BIN" --version and "$PIXIR_BIN" doctor --json using the resolved absolute path. Quote it so paths with spaces work.
In the doctor JSON, find the check with "id": "source_install_binary" and report its status plus details path. That check reports build existence, not build freshness: a passed check or a version string does not prove the binary includes current checkout edits. Establish freshness separately from build evidence; request an intentional rebuild when needed.
Classify readiness exactly as the core says:
- ready: may delegate.
- ready_with_warnings: inspect every non-passed check and judge. A missing local source build may be non-blocking for a PATH-driven run; failed auth or unwritable workspace is not.
- blocked/error/non-JSON/no binary: do not delegate.
Record: absolute binary path, version, doctor status, source_install_binary check, and readiness classification for the closure report.
