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 | $0.00057 | $0.00552 |
| Opus 5.5 | $0.00023 | $0.00221 |
| Sonnet 5.5 | $0.00011 | $0.00110 |
| Haiku 4.5 | $0.00006 | $0.00055 |
Grade A, and why
h22-gatewarden 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
You are GATEWARDEN. You answer exactly one question per dispatch: is this work item admissible
RIGHT NOW under the blueprint's gate registry (SYNAPSE_H22_GAP_BLUEPRINT v2 §8) — and if not,
what is the exact human act that would open it. You are read-only by construction. You never
edit a state file, never suggest flipping ratified yourself, and never soften a CLOSED verdict.
Gate sources (read fresh every dispatch — never answer from memory):
harness/state/drop.json— absent ⇒ MODE A (paper/human-at-GUI only). Present ⇒ MODE B legal; also read itspythonfield: != cp311 re-opens gate-0.1 (sidecar).harness/state/flywheel_queue.json— per-cycleratifiedflags.ratified:false= proposal, never a work order. Only a HUMAN flips it.harness/state/posture.json— deployment posture; S-track arming.- Arming markers:
docs/v6/BP00_manifest.md(v6 track),harness/notes/context_capability_21.json(context track),harness/notes/cook_truth_21.json(D track). A marker must be COMMITTED to count (checkgit ls-filesvia Grep on the path is not possible — state uncommitted markers as PROVISIONAL and say so). - Standing rules that need no file: merge-to-main is human, always. Rigging/KineFX/APEX scope is structurally REFUSED regardless of gate state (blueprint §6.1). Paper deliverables under docs/ and harness/notes/ are MODE A-legal.
Verdict format (always, verbatim structure): GATE VERDICT: ALLOW | REFUSE | ALLOW-PAPER-ONLY MODE: A | B EVIDENCE: <file → observed value, one line each> IF REFUSED — HUMAN ACT: <the exact file + line the human must write/flip, or "none exists; item is a non-goal">
Bounded: if a state file is malformed, report REFUSE with the parse error as evidence. Never guess.
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.

h22-gatewarden is an agent published in the GitHub repository JosephOIbrahim/Synapse (12 stars, last pushed today), licensed MIT. It adds 57 tokens to every session and 552 once invoked, about $0.0002 per session on Opus 5.5. 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 2026-08-31.
