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 | $0.00040 | $0.01179 |
| Opus 5 | $0.00020 | $0.00589 |
| Sonnet 5 | $0.00008 | $0.00236 |
| Haiku 4.5 | $0.00004 | $0.00118 |
Grade A, and why
authdbctl 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.
How it starts
The opening of the file, as written. The whole thing — 101 lines — stays where its author put it; the contents beside it link to each section on GitHub.
AuthDB Management CLI
Ownership and Contracts
cmd/authdbctl owns application paths, configuration discovery, flags/env,
terminal input, management commands, retry decisions, and output. Use
authentication-client for the importable login protocol and token-file
contracts. Keep CLI and admin API dependencies out of pkg/authclient.
connect authenticates through /login even when the admin API is disabled.
Preserve AUTHDBCTL_* environment names and ~/.config/authdbctl defaults.
Explicit flags override environment; YAML token_path overrides the path flag.
Freshly acquired credentials replace the in-memory cache only after a successful
file save. A failed login/save must preserve previously usable credentials.
Keep one buffered reader per wrapper for plain identity input; creating readers for consecutive prompts can discard piped lines. Hidden prompts use a real terminal, with terminal state owned by the caller and restored on completion, error, or context timeout. The raw-mode line editor handles Ctrl-C/Ctrl-D as EOF. A pending read must not change OS terminal settings after cancellation. Prompt cancellation ends the command; do not start another prompt while that read is pending. Do not move terminal IO into the reusable authentication package.
Management requests attach opaque credentials and reuse the cache. Access denial
may cause a fresh login only when another attempt remains. System messages have
token attachment disabled and must not trigger login. Validate management HTTP
200 bodies as JSON objects and reject status: failure; a failed mutation must
return an error without retrying. Malformed responses, including null, must
not produce a successful command exit. Preserve the original successful JSON
body for output, including generated credentials the command is meant to return.
Never put response bodies or configured secrets in error diagnostics.
Marshal realm/user fields as JSON rather than interpolating strings. A user update selects exactly one operation; reject absent or conflicting selections before configuration, login, or mutation. Hash generation may print the new hash and intentionally generated API key, but must not print supplied password fragments. Report encryption-key setup failures as errors.
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

authdbctl is a skill published in the GitHub repository greenpau/go-authcrunch (59 stars, last pushed yesterday), licensed Apache-2.0. It adds 40 tokens to every session and 1,179 once invoked, about $0.0002 per session on Opus 5. 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 2026-09-13.
