Getting it into your agent
This one installs as part of its plugin. Adding the marketplace and installing the plugin brings it with everything else the plugin ships.

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 | $0.00093 | $0.00349 |
| Opus 5.5 | $0.00037 | $0.00140 |
| Sonnet 5.5 | $0.00019 | $0.00070 |
| Haiku 4.5 | $0.00009 | $0.00035 |
Grade A, and why
show-wpf-dev-pack-config scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
What it actually says
Show WpfDevPackMcp Configuration
Print the on-disk WpfDevPackMcp configuration and server state so the user can see exactly what the MCP server reads and from where.
Run the file-based app and surface its output verbatim:
dotnet "${CLAUDE_PLUGIN_ROOT}/scripts/ShowWpfDevPackConfig.cs"
It prints the absolute paths and current contents of:
~/.wpf-dev-pack-mcp/config.json— user-writtenrepoPath+branch~/.wpf-dev-pack-mcp/state.json— server-managedLastPullUtc+Managed
plus the WPFDEVPACK_REPO_PATH and WPFDEVPACK_PULL_TTL_MINUTES environment
overrides. When WPFDEVPACK_REPO_PATH is set it overrides config.json's
repoPath — a common cause of "the MCP isn't reading the repo I configured."
To change values: /wpf-dev-pack:set-repo-path (repoPath), /wpf-dev-pack:set-repo-branch (branch), /wpf-dev-pack:set-repo-managed (Managed flag).
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.

show-wpf-dev-pack-config is a skill published in the GitHub repository christian289/dotnet-with-claudecode (41 stars, last pushed 2mo ago), licensed MIT. It adds 93 tokens to every session and 349 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 2026-09-03.
