A one-attempt bug-fixing workflow that chooses an approach different from fixes already tried, applies it, and tests the result. It reports whether that alternative worked.

Use it when you have a specific bug, target files, and a command that can verify the fix; do not use it for general code review, test-only requests, or PR summaries.

It provides an independent, evidence-based attempt when an existing fix has not solved the problem. The required test command makes the outcome verifiable rather than speculative.

How dotnet/maui configures Claude Code and Codex

About the project

.NET MAUI is a C# and XAML framework for building native mobile and desktop applications from one shared codebase. Developers use it to create apps for Android, iOS, iPadOS, macOS, and Windows. The catalogue entries provide skills, instructions, and agents for working with .NET MAUI.

SkillSpector: 2 findings, up to high

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

high Memory Poisoning · line 558
Skill manipulates agent memory, state, or stored context. Memory corruption can alter personality, override safety rules, or cause unpredictable behavior.

Fix: Protect agent memory and state from modification by untrusted content. Use read-only memory for critical instructions and validate all state changes.
medium Excessive Agency · line 492
Skill allows unbounded resource consumption (API calls, storage, compute). Without rate limits or quotas, a compromised or misbehaving agent can cause denial-of-service or cost overruns.

Fix: Set explicit rate limits, timeouts, and resource quotas for API calls, file operations, and compute. Implement circuit breakers for runaway loops.

Token cost

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	$0.00060	$0.08078
Opus 5.5	$0.00024	$0.03231
Sonnet 5.5	$0.00012	$0.01616
Haiku 4.5	$0.00006	$0.00808

Security

Grade A, and why

try-fix 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.

Try Fix Skill

Attempts ONE fix for a given problem. Receives all context upfront, tries a single approach, tests it, and reports what happened.

Activation Guard

🚨 This skill is ONLY for proposing and testing code fixes. Do NOT activate for:

Code review requests ("review this PR", "check code quality")
PR summaries or descriptions ("what does this PR do?")
Test-only requests ("run tests", "check CI status")
General questions about code or architecture

If the prompt does not include a problem to fix and a test command to verify, this skill should not run.

Core Principles

Always run once activated - Never question whether to run. The invoker decides WHEN, you decide WHAT alternative to try
Single-shot - Each invocation = ONE fix idea, tested, reported
Alternative-focused - Always propose something DIFFERENT from existing fixes (review PR changes first)
Empirical - Actually implement and test, don't just theorize
Context-driven - Work with what's provided and git history; don't search external sources
Script-only restoration - The ONLY permitted cleanup command is pwsh .github/scripts/EstablishBrokenBaseline.ps1 -Restore. Never use git checkout, git clean, git restore, git reset, or git stash to revert or clean changes, including after artifacts have been captured.
Baseline-file boundary - After Step 2, modify ONLY files listed in .github/.baseline-state.json under RevertedFiles. The restore script tracks only those original fix files; editing any other tracked file makes restoration incomplete. If the state file is absent, or its NewFiles array is non-empty, report Blocked before editing: added production files are not safely restorable. If the approach requires another tracked file, report Blocked instead of editing it.
Preserve pre-existing untracked paths - Never modify or delete an untracked file or directory that existed before the attempt. Evaluators may inject the loaded skill as an untracked directory such as try-fix/; leave it exactly as found even when git status --short lists it. It is harness-owned input, not attempt-created drift. The restore script is the only cleanup step; do not use rm, Remove-Item, or another filesystem command to make the worktree appear clean.
Wait for command completion - If a shell tool reports that a command is still running and returns a shellId, call read_bash with that exact shellId and wait for the completed result. Never proceed, report, or end the session while baseline, test, artifact, self-review, or restore work is still running.
Contain attempt artifacts - Create every log, snapshot, state marker, and scratch file under $OUTPUT_DIR. Never persist $OUTPUT_DIR or other shell state in .github/, the repository root, or another workspace path. Shell variables do not persist between tool calls, so redeclare the same literal $OUTPUT_DIR at the start of each later shell command instead of writing a repository marker file.

Changes

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.

try-fix is a skill published in the GitHub repository dotnet/maui (23,322 stars, last pushed today), licensed MIT. It adds 60 tokens to every session and 8,078 once invoked, about $0.0002 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.
