What is headsup-colors?

A skill for changing the colors of iTerm2 tabs used by Codex sessions in idle, working, and waiting states.

Use it when you want to change Codex tab colors, including the active working color.

It makes different session states easier to recognize from the terminal.

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	$0.00041	$0.00189
Opus 5.5	$0.00016	$0.00076
Sonnet 5.5	$0.00008	$0.00038
Haiku 4.5	$0.00004	$0.00019

Security

Grade A, and why

headsup-colors 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 2mo 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.

What it actually says

Codex Headsup Colors

Edit ~/.codex/hooks/headsup-status.conf. Change only these variables:

IDLE_COLOR
PROCESS_COLOR
WAIT_COLOR

Accept 6-character hex values without #, or translate common color names yourself. Preserve all other file content.

After editing, if PROCESS_COLOR changed, apply it immediately to the current tab because Codex is currently working:

~/.codex/hooks/headsup-codex-resync.sh

If only idle or waiting changed, tell the user the new color will appear on the next matching Codex state.

Do not edit Claude files under ~/.claude.

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.
