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 | $0.00039 | $0.00830 |
| Opus 5.5 | $0.00016 | $0.00332 |
| Sonnet 5.5 | $0.00008 | $0.00166 |
| Haiku 4.5 | $0.00004 | $0.00083 |
Grade A, and why
github-code-search 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 — 107 lines — stays where its author put it; the contents beside it link to each section on GitHub.
GitHub Code Search as Context
Why This is Copilot-Exclusive
Copilot CLI includes built-in GitHub MCP tools for global code search and repository inspection. That makes it practical to search for real implementations on GitHub, read the matching files, and bring the results back into your current task without leaving the CLI.
When to Use
- You want grounded implementation examples before writing a new pattern
- You need to compare how multiple repositories solve the same problem
- You want to inspect real API usage instead of relying only on memory or docs
- You need cross-repository context before making a design decision
When NOT to Use
| Instead of github-code-search | Use |
|---|---|
| Searching your current local repository | direct search tools |
| GitHub Issues, PRs, or Actions workflows | github-issue-triage, github-pr-workflow, or actions-debugging |
| Documentation-heavy research | deep-research |
| Broad MCP setup guidance | mcp-ecosystem |
Workflow
1. Form a focused query
Use GitHub code search qualifiers to keep results tight:
language:TypeScript "circuit breaker" "retry"
org:microsoft path:src/auth "refresh token"
filename:SKILL.md "Use when" "GitHub MCP"
2. Search with the built-in GitHub MCP
Tool: github-mcp-server-search_code
query: "language:TypeScript \"circuit breaker\" retry"
perPage: 10
3. Read the most relevant files
After finding candidate matches, inspect the actual source:
Tool: github-mcp-server-get_file_contents
owner: "example-org"
repo: "example-repo"
path: "src/retry.ts"
4. Reuse results as grounded context
Treat the retrieved code as external reference material:
Use the GitHub examples above as reference only.
Implement the same pattern in our repo, but adapt naming, boundaries, and tests
to local conventions.
Common Query Patterns
| Goal | Query example |
|---|---|
| Find API usage examples | "supabase.auth.signIn" language:TypeScript |
| Find config patterns | filename:docker-compose.yml "healthcheck" "interval" |
| Find error-handling conventions | "catch (error)" "instanceof" language:TypeScript NOT test |
| Find comparable skills | filename:SKILL.md "Use when" "GitHub MCP" |
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.
- 1mo ago First seen · 107 lines · 39 tokens per session scan A cd87f1187c99
github-code-search is a skill published in the GitHub repository drvoss/everything-copilot-cli (47 stars, last pushed 24d ago), licensed MIT. It adds 39 tokens to every session and 830 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.
