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 | $0.00000 | $0.00476 |
| Opus 5 | $0.00000 | $0.00238 |
| Sonnet 5 | $0.00000 | $0.00095 |
| Haiku 4.5 | $0.00000 | $0.00048 |
Grade A, and why
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 yesterday.
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 Agent Configuration
## Packaged Runtime Kit
The active Codex ControlStore runtime kit lives in
`src/multi_agent_brief/runtime_kits/codex/` and is installed into
workspaces by `briefloop runtime install --runtime codex`. Its agent
inventory is hash-bound into the Store adapter binding.
- `briefloop-source-planner.toml` — Lightweight Source Planner for choosing source-discovery categories, domains, and search tasks from the user/config profile. Writes source_candidates.yaml as a plan only, not evidence.
-
briefloop-source-provider.toml— Configures and validates source inputs, then normalizes provider outputs supplied by the deterministic runtime host. -
briefloop-scout.toml— Discovers source-grounded candidate items and, in default topology, screens them in one stage while keeping candidate_claims and screened_candidates as distinct artifacts. -
briefloop-screener.toml— Strict-topology independent screening role that filters, ranks, deduplicates, freshness-checks, and capacity-caps Scout candidates before Claim Ledger. -
briefloop-claim-ledger.toml— Converts screened candidates into source-grounded claim drafts for deterministic Python freezing into the Claim Ledger. -
briefloop-analyst.toml— Drafts the Analyst working brief from Claim Ledger entries; Python freezes that draft into analyst_draft_snapshot at analyst stage-complete. -
briefloop-editor.toml— Delivery Editor alias for the editor stage; improves clarity, structure, tone, and executive readability without adding facts. -
briefloop-auditor.toml— Audits source support, freshness, unsupported numbers, redaction risk, duplicate claims, placeholders, and harness failures.Each agent TOML file includes: - `name` - `description` - `developer_instructions` ## Skills Located in `.agents/skills/*/SKILL.md`. Skills are hand-maintained because they are runtime prompts, not simple platform config projections. ## Config `config.toml` sets: ```toml max_threads = 6 max_depth = 1 ```
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 is an agent published in the GitHub repository Stahl-G/briefloop (9 stars, last pushed 3d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 476 tokens. 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.
