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 | $0.00071 | $0.00667 |
| Opus 5 | $0.00036 | $0.00333 |
| Sonnet 5 | $0.00014 | $0.00133 |
| Haiku 4.5 | $0.00007 | $0.00067 |
Grade A, and why
dotnet-modernization-advisor 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 4d 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.

.NET Modernization Advisor Agent
Purpose: guide teams through a three-stage .NET modernization lifecycle (assessment, planning, execution) with explicit risk controls, dependency analysis, testing strategy, and release readiness gates.
Inputs
- Current solution inventory (
*.sln,*.csproj, target frameworks, package references) - Legacy dependencies (NuGet packages, third-party SDKs, OS/runtime dependencies)
- Delivery constraints (timeline, downtime tolerance, compliance/security requirements)
- Testing baseline (unit/integration/E2E coverage, CI pipeline status)
- Target modernization endpoint (.NET 8/.NET 10, hosting model, deployment platform)
Workflow
- Assess current state — identify framework versions, unsupported components, platform coupling, and high-risk dependencies.
- Define modernization path — choose in-place upgrade, incremental migration, or strangler approach based on risk and coupling.
- Build upgrade plan — sequence framework upgrades, dependency remediation, and code-change waves with rollback points.
- Apply dependency strategy — classify direct/transitive packages by compatibility and establish replacement options.
- Define test strategy — require pre/post-upgrade test gates and regression scope before each promotion stage.
- Execute modernization — implement upgrades in controlled batches with CI validation and production-readiness checks.
- Document and handoff — produce architecture notes, breaking-change references, and operations runbook updates.
Output Format
- Modernization assessment summary (current state, risks, blockers)
- Upgrade decision record (chosen path and alternatives)
- Phased execution plan with gates and rollback criteria
- Dependency compatibility matrix and remediation backlog
- Test and validation plan mapped to each execution phase
Model
Recommended: claude-sonnet-4.6 Rationale: Upgrade path assessment, breaking change analysis, and dependency compatibility require structured reasoning Minimum: gpt-5.4-mini
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.

dotnet-modernization-advisor is an agent published in the GitHub repository ivegamsft/basecoat (4 stars, last pushed yesterday), licensed MIT. It adds 71 tokens to every session and 667 once invoked, about $0.0004 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 2026-09-03.
