codex-session

An offline report showing Codex, OpenAI’s coding agent, usage grouped by session. It supports the established `ccusage-codex session` command format and can also produce JSON.

In plain words
What is it for?
Use it to filter sessions by date, sort them, inspect token usage, or create a Codex-labelled shareable report.
Why use it?
It lets you review Codex sessions locally while keeping the expected command and accounting behavior.

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.

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 B, and why

codex-session scanned grade B with 1 finding 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.

Reads agent configuration directoriesmediumAgent snooping

.claude/, .codex/, .gemini/ hold keys, settings and other credentials a mod has no legitimate need for.

How it starts

The opening of the file, as written. The whole thing — 100 lines — stays where its author put it; the contents beside it link to each section on GitHub.

codex-session

Codex (OpenAI) usage grouped by session. Drop-in replacement for ccusage-codex session, offline.

Canonical form: cctally codex session (this flat form remains as an alias).

Config and sharing

codex-session keeps its established session accounting and inclusive Codex-token semantics. --config PATH is a read-only alternate configuration path. The common share flags (--format, --theme, --no-branding, --output, --copy, --open) produce a visibly Codex-labelled artifact; without --format, terminal, JSON, and empty output are unchanged. Review share output before it leaves the machine; see share.md.

Synopsis

cctally codex-session
    [-s YYYY-MM-DD] [-u YYYY-MM-DD]
    [-o {asc,desc}]
    [--speed {auto,standard,fast}]
    [--json]
    [-z TZ] [-l LOCALE]
    [--compact] [--color] [--noColor]
    [-O | --offline | --no-offline]
    [-d | --debug] [--debug-samples N]

Note: no --breakdown flag. Sessions don't get per-model child rows in the upstream layout, so we don't either.

Options

Flag Description
-s, --since YYYY-MM-DD Filter from date (inclusive).
-u, --until YYYY-MM-DD Filter until date (inclusive).
-o, --order {asc,desc} Sort direction by last activity (default asc — earliest first).
--speed {auto,standard,fast} Codex pricing tier. auto (default) reads service_tier from ~/.codex/config.toml; fast|priority there selects fast-tier pricing. fast/standard force the tier.
--json Output JSON matching ccusage-codex session format.
-z, --timezone TZ IANA timezone for date bucketing.
-l, --locale LOCALE No-op; accepted for drop-in compat.
--compact Force compact table layout.
--color / --noColor No-op; accepted for drop-in compat.
-O, --offline / --no-offline No-op; always offline.
-d, --debug Emit a stderr "Codex Pricing Debug Report" (totals + top-N highest computed-cost entries).
--debug-samples N Cap on top-entry sample rows (default 5; N=0 suppresses the block).

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.

codex-session is a command published in the GitHub repository omrikais/cctally (5 stars, last pushed 3d ago), licensed Apache-2.0. It costs nothing until one of its globs matches a file; then it loads 1,262 tokens. A static security scan graded it B with 1 finding (reads agent configuration directories). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
