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 | $0.00058 | $0.00938 |
| Opus 5 | $0.00029 | $0.00469 |
| Sonnet 5 | $0.00012 | $0.00188 |
| Haiku 4.5 | $0.00006 | $0.00094 |
Grade A, and why
xcode-build-fixer scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 8d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 92 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Xcode Build Fixer
Use this skill to apply approved build optimization changes and re-benchmark to verify improvements.
Non-Negotiable Rules
- Only apply changes that have explicit developer approval.
- Apply one logical fix at a time so changes are reviewable and reversible.
- Verify compilation succeeds after each change.
- Re-benchmark after all changes using the same baseline parameters.
- Do not revert best-practice settings based on single benchmark runs.
Fix Categories
1. Build Settings
Modify project.pbxproj values directly. Common examples:
DEBUG_INFORMATION_FORMAT = dwarf(Debug)COMPILATION_CACHING = YESEAGER_LINKING = YESONLY_ACTIVE_ARCH = YES(Debug)SWIFT_COMPILATION_MODE = singlefile(Debug)
2. Script Phases
- Add input/output file declarations to prevent unnecessary re-execution.
- Add configuration guards (
if [ "$CONFIGURATION" != "Debug" ]; then exit 0; fi). - Convert
alwaysOutOfDatescripts to properly declared dependencies.
3. Source-Level Fixes
Code changes that reduce compiler overhead:
- Add explicit type annotations to complex expressions.
- Mark classes
finalwhen not subclassed. - Narrow access control (
private,fileprivate). - Decompose large SwiftUI
bodyproperties into subviews. - Break long method chains with typed intermediates.
4. SPM Restructuring
- Pin branch-tracked dependencies to version tags or revision hashes.
- Extract shared contracts to break circular dependencies.
- Separate interface from implementation modules.
Execution Workflow
- Read the approved items from
.build-benchmark/optimization-plan.md. - For each approved item:
a. Identify the exact file(s) and location(s) to change.
b. Apply the change.
c. Verify compilation:
xcodebuild build. d. If compilation fails, revert and note the issue. - After all changes are applied and compiling, re-benchmark using the original baseline parameters.
- Compare results and generate the execution report.
What ships with it
3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

xcode-build-fixer is a skill published in the GitHub repository carloshpdoc/ios-workflow-claude (7 stars, last pushed 3mo ago), licensed Apache-2.0. It adds 58 tokens to every session and 938 once invoked, about $0.0003 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 2026-08-31.
