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 | $0.03060 | $0.03060 |
| Opus 5.5 | $0.01224 | $0.01224 |
| Sonnet 5.5 | $0.00612 | $0.00612 |
| Haiku 4.5 | $0.00306 | $0.00306 |
Grade A, and why
guide copilot-instructions.md 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.
How it starts
The opening of the file, as written. The whole thing — 257 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Software Development Guide Repository
This is a comprehensive documentation repository containing software development standards, best practices, and guidelines organized across multiple categories including Code Style, Life Cycle processes, and practical Cookbooks.
Always reference these instructions first and fallback to search or bash commands only when you encounter unexpected information that does not match the info here.
Working Effectively
Quick Setup and Validation
- Validate repository structure:
ls -la README.md Home.md .editorconfig .github/workflows/update-wiki.yml - Build the wiki sync tool:
cd .github/workflows/update-wiki go build -o update-wiki ./...- Build time: ~1 second. NEVER CANCEL. Set timeout to 30+ seconds for safety.
- Build the AI rules generator:
cd .github/workflows/generate-ai-rules go build -o generate-ai-rules ./... - Run basic validation:
find . -name "*.md" | wc -l(should show 80+ Markdown files)
Core Build Process
The repository has two Go-based tools under .github/workflows/:
update-wiki (Go 1.26.2)
Syncs documentation to GitHub Wiki:
- Build location:
.github/workflows/update-wiki/ - Build command:
go build -o update-wiki ./... - Expected build time: ~1 second
generate-ai-rules (Go 1.26.2)
Generates AI assistant rule files for Claude Code, Cursor, Codex, and GitHub Copilot from the guide's own documentation.
- Build location:
.github/workflows/generate-ai-rules/ - Build command:
go build -o generate-ai-rules ./... - Run:
./generate-ai-rules - Expected build time: ~1 second
NEVER CANCEL BUILD COMMANDS - Even though builds are fast (~1s), set timeouts of 30+ seconds.
GitHub Actions Workflows
Seven workflows are defined under .github/workflows/:
| File | Trigger | Purpose |

checks.yaml |
Pull request to main |
Runs shared checks via a reusable workflow in rios0rios0/pipelines |
claude-review.yaml |
PR opened/synchronize/ready_for_review/reopened | AI-assisted PR review; calls a reusable workflow in rios0rios0/pipelines |
claude-mention.yaml |
Issue/PR comments, issue events, PR reviews | Claude Code automation for issues and PRs; calls a reusable workflow in rios0rios0/pipelines |
release.yaml |
Push to main |
Automated release via reusable workflow |
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.
