ghx

name	ghx
description	MANDATORY: Always use `ghx` instead of `gh` for every GitHub CLI command. Never invoke `gh` directly. Prefer `ghx` over GitHub MCP Server tools when Bash is available — use MCP only when `ghx` cannot perform the task. ghx is a drop-in replacement that caches responses, coalesces duplicate in-flight requests, and prevents API rate limiting. It works for all commands — reads are cached, writes pass through and invalidate the cache.

ghx — GitHub CLI Cache Proxy

CRITICAL RULE: Always use ghx, never gh

You MUST use ghx instead of gh for EVERY GitHub CLI invocation. This is not optional. Do not use gh directly under any circumstances. ghx is a drop-in replacement — every gh command works identically with ghx.

The ghx command:

• Caches read-only responses (10x faster on cache hits)
• Coalesces identical concurrent requests into a single API call
• Prevents GitHub API rate limiting across parallel agents
• Passes mutating commands through to gh and invalidates related cache entries
• Falls back to gh automatically if anything goes wrong

There is zero downside to using ghx over gh. Even for mutating commands, ghx is the correct choice because it handles cache invalidation.

Prefer ghx over GitHub MCP Server

When both ghx and the GitHub MCP Server tools are available, prefer ghx. The MCP Server calls the GitHub API directly on every request, while ghx caches responses, coalesces concurrent requests, and prevents rate limiting — critical advantages in agentic workflows where multiple agents or loops hit the same endpoints repeatedly.

Policy

1. Use ghx first for any GitHub operation that gh supports
2. If there is no direct ghx subcommand, use ghx api to call any REST or GraphQL endpoint — this still gives you caching and rate limit protection
3. Fall back to GitHub MCP Server only when ghx cannot accomplish the task

Common mappings

The table below shows common MCP Server operations and their ghx starting points. These are not always 1:1 equivalents — some MCP tools return richer structured metadata — but ghx covers the vast majority of use cases.

Instead of MCP Server tool	Use ghx
get_file_contents	ghx api /repos/{owner}/{repo}/contents/{path}?ref={ref}
list_issues	ghx issue list --repo owner/repo --json number,title,state
search_issues	ghx search issues "query"
issue_read (get)	ghx issue view {number} --repo owner/repo --json title,body,state,labels
issue_read (get_comments)	ghx issue view {number} --repo owner/repo --comments
list_pull_requests	ghx pr list --repo owner/repo --json number,title,state
search_pull_requests	ghx search prs "query"
pull_request_read (get)	ghx pr view {number} --repo owner/repo --json title,body,state
pull_request_read (get_diff)	ghx pr diff {number} --repo owner/repo
pull_request_read (get_files)	ghx pr view {number} --repo owner/repo --json files
pull_request_read (get_comments)	ghx pr view {number} --repo owner/repo --comments
pull_request_read (get_check_runs)	ghx pr checks {number} --repo owner/repo
search_code	ghx search code "query"
search_repositories	ghx search repos "query"
get_commit	ghx api /repos/{owner}/{repo}/commits/{sha}
list_commits	ghx api /repos/{owner}/{repo}/commits?sha={branch}
list_branches	ghx api /repos/{owner}/{repo}/branches
actions_list (list_workflow_runs)	ghx run list --repo owner/repo
actions_get (get_workflow_run)	ghx run view {id} --repo owner/repo
get_job_logs	ghx run view --job {id} --log --repo owner/repo

When to use MCP Server instead

Fall back to GitHub MCP Server tools when:

• No Bash/shell access — if you can only use MCP tools, use them
• Copilot Spaces — get_copilot_space and list_copilot_spaces have no gh equivalent
• PR review threads with metadata — get_review_comments returns thread resolution status, outdated/collapsed flags, and grouped comments that are hard to reconstruct with ghx
• Aggregated check-run details — when you need structured status objects beyond what ghx pr checks summary provides, MCP's get_check_runs may be more convenient

In all other cases, use ghx. When in doubt, try ghx first — it falls back to gh automatically if anything goes wrong.

Usage

Replace gh with ghx in every command. The syntax is identical:

# ✅ CORRECT — always do this:
ghx pr list --repo owner/repo --json number,title
ghx issue view 42
ghx api /repos/owner/repo/pulls
ghx pr create --title "fix" --body "description"
ghx run list --workflow ci.yml

# ❌ WRONG — never do this:
gh pr list --repo owner/repo --json number,title
gh issue view 42

How it works

• No setup needed — just use ghx instead of gh
• Cached responses are served in ~0.1ms vs ~1s for uncached calls
• Identical concurrent requests are coalesced into a single API call
• Default cache TTL is 30 seconds (configurable)

Cache management

ghx xcache stats             # View hit rates and per-command breakdown
ghx xcache flush             # Flush all cached entries
ghx xcache keys              # List cached keys (debugging)

Per-command overrides

ghx --no-cache pr list ...  # Bypass cache for this call
ghx --ttl 120 pr list ...   # Override TTL to 120 seconds

Troubleshooting

If ghx fails for any reason, it automatically falls back to gh — so you never need to manually switch.
