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 | $0.00025 | $0.00486 |
| Opus 5 | $0.00013 | $0.00243 |
| Sonnet 5 | $0.00005 | $0.00097 |
| Haiku 4.5 | $0.00003 | $0.00049 |
Grade A, and why
gridview-templatefield-regression 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 5d 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.
How it starts
The opening of the file, as written. The whole thing — 44 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Context
Use this when changing the Web Forms to Blazor CLI markup pipeline anywhere near GridView column transforms, template context handling, data-binding expression rewrites, or asp-prefix stripping. TemplateField preservation is a cross-transform behavior, so regressions can appear even when each individual transform still looks correct in isolation.
Patterns
- Treat
TemplateFieldpreservation as an ordered pipeline contract:DisplayExpressionTransformAspPrefixTransformDataBindingAttributeTransformAttributeStripTransformGridViewColumnItemTypeTransformTemplateContextTransform
- Keep regression coverage at two levels:
- Transform-only markup assertions through
TestHelpers.CreateDefaultPipeline(). - Full-file migration assertions through
MigrationPipeline.ExecuteAsync().
- Transform-only markup assertions through
- Cover these GridView shapes explicitly:
- TemplateField with inner
TextBox - TemplateField with inner
CheckBox - TemplateField with inline display expression only
- Mixed
BoundField+TemplateFieldsiblings - GridView with only TemplateField columns
- TemplateField with inner
- Assert both preservation and non-regression:
- Expected
<TemplateField ...>count remains stable - Inner controls survive as BWFC components (
<TextBox>,<CheckBox>) ItemTemplate Context="Item"is present- No unexpected fallback
<BoundField>appears for template-only columns
- Expected

Anti-Patterns
- Testing only
GridViewColumnItemTypeTransformin isolation after changing template-related transforms. - Verifying only the first GridView column and assuming later TemplateField siblings survived.
- Accepting output that preserves the
TemplateFieldshell but drops nested controls or display expressions. - Changing transform order in
Program.cswithout mirroring the same coverage throughtests/BlazorWebFormsComponents.Cli.Tests/TestHelpers.cs.
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.

gridview-templatefield-regression is a skill published in the GitHub repository FritzAndFriends/BlazorWebFormsComponents (449 stars, last pushed 2mo ago), licensed MIT. It adds 25 tokens to every session and 486 once invoked, about $0.0001 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 2026-08-30.
