FlowGuard: Skill for Codex

.agents/skills/flowguard-model-mesh/SKILL.md

flowguard-model-mesh is a skill for Codex from liuyingxuvka/FlowGuard. It costs 33 tokens per session (668 once invoked), scanned A, original, MIT.

A skill for reviewing ownership, evidence freshness, partitions, reattachments, sibling models, and closure across a connected model hierarchy. It applies when work spans multiple related models.

In plain words
What is it for?
Checking model relationships, verifying evidence and receipts, reopening affected children or siblings, and deciding whether a cross-model review is complete.
Why use it?
It helps prevent incomplete whole-flow conclusions when parts of a connected system are missing, stale, separated, or not properly reassigned.

Skill for Codex

Written for Codex: agents/openai.yaml present. Also seen: installed under .agents/ (shared by several agents); mentions AGENTS.md.

This is liuyingxuvka/FlowGuard's own configuration. It tells Codex how to work on FlowGuard itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything FlowGuard configures →

Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

flowguard-model-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 Model Mesh

Purpose

Govern ownership, evidence tiers/freshness, partitions/reattach, siblings/closure.

Entrypoint Scope

A standalone FlowGuard satellite skill; owns hierarchy, not test/code splits.

Local Material Routing

After admission read references/model_mesh_protocol.md; load references/model_mesh_partition_protocol.md, references/model_mesh_reattachment_protocol.md, or references/model_mesh_closure_protocol.md only when triggered.

Entrypoint Acceptance Map

Accept children; verify partitions/receipts; block incomplete closure.

Use When

  • A relation crosses models, a model is oversized/incomplete, or a changed child/sibling/whole-flow claim needs review.

Do Not Use When

  • Do not trigger on count, split tests/code, promote child-local green, or handle ordinary one-model work; use flowguard.

Required Workflow

  1. Inventory hierarchy, owners, partitions, and evidence freshness. Whole-flow claims disposition all models/relations.
  2. Consume compact path-quality fingerprints. Reopen only changed children, ancestors, consumers, and siblings; ModelMaturation retains single-model judgment.
  3. Review disjointness, Child Reattachment Gate, siblings, receipts, leaves, and closure. Topology may trigger deep review, never a second path comparison.
  4. In blueprint scope, connect purpose, producers/consumers, realization refs to independent inventory/binding identities without copying semantics.
  5. Consume flowguard.portable_refinement.v1; hand gaps/cases/receipts to alignment, test, risk, or portable owners without a second interpreter.

Hard Gates

  • Model-purpose gate: freeze task-specific failure(s) and claim_boundary; bind the candidate to 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.
  • One logical model has one current instance; fingerprints bind model, runner, purpose, and inputs. Compile exact ownership before execution; never rerun-all.
  • Multi-model replacement is one revision. Partial activation, stale head, omitted sibling, overlap, incomplete relation, stale receipt, or missing path-quality row blocks parent confidence.
  • Ordinary work materializes affected topology; blueprint-wide topology needs explicit scope and never triggers repository discovery.
  • Parent projections omit deep candidates/witnesses/costs. normative_target cannot replace observed until implementation/evidence match.
  • ModelMesh proves relationships, not semantics, path quality, inventory, or qualification; counts prove none.

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-model-mesh is a skill published in the GitHub repository liuyingxuvka/FlowGuard (2 stars, last pushed 14d ago), licensed MIT. It adds 33 tokens to every session and 668 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.
