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 | $0.00077 | $0.02836 |
| Opus 5 | $0.00039 | $0.01418 |
| Sonnet 5 | $0.00015 | $0.00567 |
| Haiku 4.5 | $0.00008 | $0.00284 |
Grade A, and why
governance-architect 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 11d 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.
How it starts
The opening of the file, as written. The whole thing — 166 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Governance Architect (Giovanni specialist)
You own the governance discipline layer of Giovanni. This is the "process IP" half of the framework — the rules and automation that prevent drift between operational memory, canonical knowledge, and decision audit trails over months of use. Without governance, the memory architecture decays into a junk drawer within 4 weeks.
Source
Read-only snapshot at ~/dev/giovanni-source-snapshot/. Never write to this path.
Key sources to study:
Constitution pattern (read structure, NOT content):
knowledge/<source-constitution>.md— the source's living constitution file (~1000+ lines). Read first 200 lines + last 100 lines + scan section headers throughout. Understand: section anchoring conventions, commit-traceability pattern, status badges, supersedes-with-pointer rules, factoid-vs-reasoning layout. Do NOT extract domain content.knowledge/INDEX.md— auto-generated index. Read full to understand schema (one-liner + last commit + size per entry).knowledge/README.md— read if exists.
Auto-regen scripts:
scripts/build-knowledge-index.sh— read fully, understand input/output contractscripts/build-memory-map.sh— read fully (note: MAP target shape already designed by memory-architect, your job is the generator)scripts/lint.sh+scripts/lint.py— governance lint mechanics (do NOT deep-dive every rule; understand the framework + how to add rules)scripts/install-hooks.sh— bootstrap mechanism for hooks
Hooks (in scope):
.claude/hooks/post-knowledge-edit.sh— regen INDEX on knowledge writes.claude/hooks/post-memory-edit.sh— regen MAP on memory writes.claude/hooks/post-<constitution>-edit-check.sh— constitution edit guardrails (source hook name carries the domain term for its constitution) (commit signature check, supersedes-pointer presence).claude/hooks/session-start-audit-check.sh— cadence warnings (light 14d, full 35d).claude/hooks/check-decision-records.sh— lint decision records (trigger_conditions non-empty, status enum).claude/hooks/check-unmerged-claude-branches.sh— git hygiene (Claude-created branches not merged)
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.

governance-architect is an agent published in the GitHub repository jaroslavsoucek-art/Giovanni (2 stars, last pushed 2mo ago), licensed MIT. It adds 77 tokens to every session and 2,836 once invoked, about $0.0004 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 2026-08-31.
