Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00105 | $0.00424 |
| Opus 5.5 | $0.00042 | $0.00170 |
| Sonnet 5.5 | $0.00021 | $0.00085 |
| Haiku 4.5 | $0.00011 | $0.00042 |
Grade A, and why
workflow-foundation 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 1mo 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
Windows Workflow Foundation
Trigger On
- working on WF activities, workflows, or designer-backed process logic
- reviewing long-lived workflow state and persistence behavior
- assessing whether to keep, isolate, or replace Workflow Foundation
Workflow
- Treat WF as legacy infrastructure and start by understanding what workflow behavior is still business-critical before proposing replacement.
- Separate workflow host concerns, activity logic, persistence, and integration points so risk is visible.
- Avoid half-migrations that leave workflow state and business rules split across two orchestration systems without ownership.
- If replacement is needed, define explicit equivalence for triggers, compensation, persistence, and audit expectations.
- Stabilize current behavior with targeted tests or scenario captures before changing designer-driven artifacts.
- Validate with representative long-running and failure scenarios, not just a single successful execution path.
Deliver
- practical maintenance or migration guidance for WF
- clear boundaries around host, workflow, and persistence responsibilities
- risk-aware change plans for legacy process logic
Validate
- business-critical workflow behavior is identified before change
- migration work preserves state and audit expectations
- designer artifacts are treated carefully
References
- Migration Guidance - decision framework for keeping, replacing, or isolating WF; migration targets and steps; common pitfalls
- Maintenance Patterns - host management, persistence, activity design, testing, and operational patterns for WF systems
What ships with it
3 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.

workflow-foundation is a skill published in the GitHub repository managedcode/dotnet-skills (496 stars, last pushed yesterday), licensed MIT. It adds 105 tokens to every session and 424 once invoked, about $0.0004 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 2026-08-30.
