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 | $0.00048 | $0.00646 |
| Opus 5 | $0.00024 | $0.00323 |
| Sonnet 5 | $0.00010 | $0.00129 |
| Haiku 4.5 | $0.00005 | $0.00065 |
Grade A, and why
flowguard-structure-mesh 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 9d 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.

FlowGuard Structure Mesh
Purpose
Govern an existing-code split while preserving public entrypoints, facades, config, effects, cycles, and parity.
Entrypoint Scope
A standalone FlowGuard satellite skill; owns structure_mesh_maintenance (public_owner) evidence, not behavior invention or edits.
Local Material Routing
After admission, read references/structure_mesh_protocol.md for target derivation, partitions, evidence scopes, and handoffs.
Entrypoint Acceptance Map
Accept a named model/surface; derive child ownership; block facade/owner/cycle/config/parity gaps; hand evidence onward.
Use When
- Use for splitting large code surfaces, moving public imports/CLI/API/data/plugin entrypoints, dividing state/config/side effects, or checking dependency cycles and parity.
Do Not Use When
- Do not derive behavior requirements from scratch, recommend greenfield modules, refactor code directly, or claim parity from internal/formatting checks; return unclear models to
flowguard.
Required Workflow
- Accept ArchitectureReduction only with universe member, observable contract, current equivalence/facade proof, consumers/tests, action, and next route; otherwise unresolved. Derive modules from named model maps.
- Partition functions, state, config, effects, contracts, dependencies, public entrypoints, and facades to single owners.
- For blueprint scope, consume the independent inventory fingerprint and exact required ids; require one owner or terminal disposition per surface.
- Attach current routine/release parity and hand gaps/obligations downstream.
Hard Gates
- Model-purpose gate: freeze task-specific failure(s)/claim_boundary; bind native good/bad-per-failure/oracle/current evidence. Reusable types are not fixed-purpose: no mode/fallback; only FlowGuard-declared checks may support completion claims. Require real FlowGuard check engine and AGENTS.md managed record; forbid a fake mini-framework.
- Missing target structure, facade, owner, compatibility, or current parity blocks its scope. StructureMesh does not discover source; stale inventory, omitted surfaces, or fingerprint mismatch blocks blueprint closure.
- ArchitectureReduction requires a concrete universe member, contract, current proof, target action, and next route; similarity, size, or origin is not proof.
- Dependency/config and release-only gaps stay visible.
- Only explicit reuse/publication or proven cross-project use triggers strict
risk_template_libraryclosure. - Blueprint depth/first gap, explicit whole scope, affected-only default, exact ownership, and separate decision axes follow the protocol.
What ships with it
5 files 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.

flowguard-structure-mesh is a skill published in the GitHub repository liuyingxuvka/FlowGuard (2 stars, last pushed 13d ago), licensed MIT. It adds 48 tokens to every session and 646 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 2026-08-31.
