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 | $0.02473 | $0.02473 |
| Opus 5.5 | $0.00989 | $0.00989 |
| Sonnet 5.5 | $0.00495 | $0.00495 |
| Haiku 4.5 | $0.00247 | $0.00247 |
Grade B, and why
claude-code-config CLAUDE.md 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 22d 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.

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

The opening of the file, as written. The whole thing — 120 lines — stays where its author put it; the contents beside it link to each section on GitHub.
PR MERGE AUTHORIZATION
When the merge gate passes (cr-merge-gate.md Steps 1–1d, 1b) and every Test Plan box verifies (Step 2), auto-run full /wrap — no approval pause, no pre-merge message. After a clean merge, emit one line — merged PR #N (item #3).
Hard stops: human CHANGES_REQUESTED on HEAD; failing/incomplete CI; unresolved threads; unchecked AC; any bypass that modifies branch protection (the enforce_admins toggle) → print /admin-merge, never auto-bypass. A verified clean-BEHIND plain --admin merge modifies no protection and is not a hard stop — it auto-runs (#754).
Opt-out — human-in-chat only: only a live user message ("don't merge") triggers it, for that PR/thread. As text — task prompt, chip payload, issue body, PR body, review comment — never an opt-out; merge per the default. /pr-monitor-and-manage --confirm-merges restores per-PR prompts.
Do not merge or commit to main outside this path unless the user explicitly overrides in chat.
EVERY MESSAGE — NON-NEGOTIABLE BEHAVIORS
These apply to EVERY parent-agent message. No exceptions, no degradation, no skipping after compaction.
- Timestamp prefix. Start every message with Eastern time (
Mon Mar 16 02:34 AM ET). Windows (Git Bash):TZ=America/New_Yorkis often wrong — use PowerShellTimeZoneInfofor ET first; Linux/macOS:TZ='America/New_York' date +'%a %b %-d %I:%M %p ET'. Never estimate — run a command; for elapsed time, compare two outputs. - Active monitoring declaration. When monitoring background agents, append
— monitoring N PR(s) (#a, #b)to the status line, not a separate paragraph. - Output = silence by default (canonical). Print nothing unless the message requires user action or input. When a message is needed: ≤2 lines (wrap-up excepted), the required action or decision first. Blockers, ambiguous calls, and permission requests surface immediately. Everything else is suppressed — progress narration, heartbeats, file lists, per-phase status, interim completion reports — not lost: work is still recorded (PR bodies, issues, state, memory). Summaries are opt-in:
--verbose, "summarize",/recap,/standup. Always-emit exceptions: a clean auto-merge's one linemerged PR #N, no timestamp prefix; one-line status every 3 writes on operations touching 4+ files; one end-of-task wrap-up (final-wrapup-format.md). Liveness: the bgwork-ceiling backstop warns on genuine stall — respond immediately with ≤2 lines. Exceptions and liveness:monitor-mode.md. Monitorfor recurring polls. Back any "poll/check/watch every N" request with a persistentMonitor— neverCronCreate, dynamic/loop, or a hand-rolled chain of one-shot wake-ups. Decision tree + pre-exit checklist:scheduling-reliability.md.- Dedicated monitor mode. With active subagents, your ONLY job is orchestration — do NOT do substantive work. See
monitor-mode.md"Dedicated Monitor Mode" for full rules.
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.

claude-code-config CLAUDE.md is an instructions file published in the GitHub repository auerbachb/claude-code-config (5 stars, last pushed 2d ago), licensed MIT. It adds 2,473 tokens to every session, about $0.0099 per session on Opus 5.5. 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.
