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.

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 | $0.00055 | $0.02592 |
| Opus 5 | $0.00028 | $0.01296 |
| Sonnet 5 | $0.00011 | $0.00518 |
| Haiku 4.5 | $0.00006 | $0.00259 |
Grade A, and why
clang-format 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.

clang-format Configuration
Configure the clang-format code formatting tool using ready-to-use templates, integration scripts, and comprehensive reference documentation.
Purpose
This skill provides procedural workflows for clang-format configuration tasks:
- Create new .clang-format files from proven templates
- Analyze existing code style and generate matching configurations
- Set up editor and git integration with bundled scripts
- Troubleshoot formatting behavior using reference documentation
Workflow Routing by Trigger Type
Once invoked, route to appropriate workflow based on which trigger fired:
Trigger 1: Explicit clang-format mention → If user asks about specific options: Consult references/01-09.md for relevant category → If user needs complete reference: Direct to references/complete/clang-format-style-options.md → If user asks about CLI usage: Reference references/cli-usage.md
Trigger 2: Code style analysis request → Follow "Analyzing Existing Code Style" workflow below → Examine code samples systematically (braces→indentation→spacing→breaking→alignment) → Map patterns to closest template in assets/configs/ → Generate initial configuration hypothesis as a temporary configuration file "/tmp/<reponame>/hypothesis.clang-format" → VERIFY IMPACT: Run clang-format --style="/tmp/<repo_name>/hypothesis_<number>.clang-format" file.cpp | diff - file.cpp on 3-5 representative samples → MEASURE IMPACT using weighted scoring: • Metric 1: Line count changes (lines added/removed) - weight 10 • Metric 2: In-line whitespace changes (spacing within existing lines) - weight 1 • Impact Score = (line_count_changes × 10) + (whitespace_changes × 1) • Lower score = lower impact to rebasing conflicts, future git-diff analysis, and merge request change reviews = better configuration → ITERATE: Adjust config options targeting highest-impact settings, re-test, compare scores → REPEAT until reaching minimal achievable score while maintaining consistent style enforcement → REPORT TO USER: Present winning configuration with: • Final impact score and breakdown (line changes vs whitespace changes) • Comparison table showing all tested hypotheses and their scores • Example diff snippets showing what will change, with commands for the user to test it themselves against files of their choice. • Rationale for selected configuration → AWAIT USER APPROVAL before finalizing configuration → Only after approval: provide final configuration file

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.

clang-format is a skill published in the GitHub repository Jamie-BitFlight/claude_skills (66 stars, last pushed today), licensed MIT. It adds 55 tokens to every session and 2,592 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 2026-09-03.
