workflow-canon

A set of rules and checks for designing or reviewing workflow definitions in a specific workflow-server repository.

In plain words
What is it for?
Use it to audit files such as workflow.yaml, activities, techniques, resources, and READMEs, provided the required canon files are present.
Why use it?
It helps prevent inconsistent designs and directs you to the repository’s authoritative guidance instead of copying rules into multiple places.

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

workflow-canon 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 — 123 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Workflow Canon

The canon is four criteria homes plus a guard suite, all on disk in this repo.

This skill holds no criteria of its own. It locates the homes, enumerates their units, walks them, and reports. Copying Detect or stance text into this file would create a second home that drifts from the first — the defect the catalog itself names as canon-layer-cites-not-restates and no-duplicated-guidance. Cite entries by their kebab-case name; never by a bare AP-XX number and never by any count of the catalog's entries.

Homes

Locate the checkout first. Every path below is relative to the workflow-server repo root. When the cwd is inside the checkout, git rev-parse --show-toplevel gives it. When the session is rooted in a cursor workspace instead — a directory holding .mcp.json and a *.code-workspace but no workflows/ — the checkout is the project folder that *.code-workspace names, and it is an additional working directory of the session.

Confirm the resolved root holds workflows/workflow-design/resources/ before reading anything. workflows/ is a git submodule, so a shallow checkout may not have it; if the canon files are absent, say so rather than auditing from memory.

Home Path Owns
Design Principles workflows/workflow-design/resources/design-principles.md Prefer / before / only after stance. One unit per ## section.
Anti-Patterns workflows/workflow-design/resources/anti-patterns.md Specific smells as Detect / Do not flag / Fix. One unit per ## family section. ~1700 lines — fetch by anchor.
Schema Construct Inventory workflows/workflow-design/resources/schema-construct-inventory.md Informal-prose → formal-construct mappings. One unit per ## section.
Convention Conformance workflows/workflow-design/resources/convention-conformance.md Comparison against sibling workflows. One unit.
Guard suite scripts/guards.ts (registry) Mechanical checks. The registry is the enumeration — never maintain a parallel list.

Files

What ships with it

2 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.

Changes

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.

workflow-canon is a skill published in the GitHub repository m2ux/workflow-server (1 stars, last pushed 2d ago), licensed Apache-2.0. It adds 127 tokens to every session and 2,954 once invoked, about $0.0006 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.
