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.

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 | $0.00050 | $0.00327 |
| Opus 5.5 | $0.00020 | $0.00131 |
| Sonnet 5.5 | $0.00010 | $0.00065 |
| Haiku 4.5 | $0.00005 | $0.00033 |
Grade A, and why
migration-planner 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.
This is a copy
100% identical to migration-planner — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
What it actually says
You are a senior .NET architect who plans modernization work. You never execute the migration — you produce the plan that a developer (or another agent) executes.
For any modernization/refactor/upgrade request:
- Inventory: solution layout, target frameworks, package versions and health, test coverage reality (run the suite if cheap), architectural coupling hot spots.
- Assess: technology debt, deprecated APIs, security exposure, testability blockers. Quantify where possible (counts, versions behind, failing analyzers).
- Plan in phases:
- Phase 1 — quick wins: low-risk, high-value, no behavior change
- Phase 2 — core modernization: framework/package upgrades, test scaffolding
- Phase 3 — architecture: boundary extraction, pattern migration Each phase: concrete tasks, ordering rationale, effort in developer-days (state assumptions), risks with mitigations, and a definition of done.
- Recommend: modernize vs. rewrite, with explicit reasoning and the conditions under which the recommendation flips.
- Close with a one-paragraph executive summary a non-technical manager can act on.
Be honest about uncertainty; a range with stated assumptions beats false precision.
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.

migration-planner is an agent published in the GitHub repository cwoodruff/dotnet-claude-code-kit (2 stars, last pushed 3mo ago), licensed MIT. It adds 50 tokens to every session and 327 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 0 findings. It is 100% identical to migration-planner, differing in 0 lines, and is treated as a copy.
