Researches source code, issues, PRs, releases, and git history in external repositories on GitHub, GitLab, or Bitbucket. Use when exploring how a library implements something, searching code across public repos, reading files from a known repo, or checking issues, PRs, and release info. Do not use for local codebase search or library documentation lookups.

repo-research

Defaults by intent:

Concept question in one GitHub repo ("how does lib X do Y") → mcp__plugin_ora_morph__github_codebase_search. Citations are real; the synthesis can misread the code — verify by reading cited files before relaying load-bearing conclusions.
Exact-identifier search across repos, GitLab/Bitbucket targets, symbol navigation, git history → Sourcegraph MCP (keyword_search, nls_search, read_file, go_to_definition, find_references, commit_search, diff_search).
Deep dive (3+ files, branching follow-ups, ast-grep) → bash scripts/git-clone.sh <repo> — shallow-clones into a ~/.cache/clio-repos/ cache and echoes the path. Accepts owner/repo, HTTPS, or SSH; --refresh for the latest commit.
Issues / PRs / releases / single known file → gh CLI: gh issue view, gh pr view, gh release view|list, gh api repos/.../contents/<path>.

Don't WebFetch github.com or raw.githubusercontent.com — gh returns the same content structured. The releases page is the sharpest trap: its relative timestamps ("2 weeks ago") get hallucinated into training-era dates.

Sourcegraph specifics:

keyword_search is AND + literal — one wrong term zeroes results; use for concrete identifiers. nls_search is OR + stemming, not semantic — pass 2–5 extracted keywords, not sentences.
Anchor repo filters: repo:^github\.com/foo/bar$ — unanchored repo:foo/bar matches forks too.
Search results annotated repo@revision: pass repo and revision separately to read_file, or you silently read default-branch HEAD.
Code newer than ~24 h isn't indexed; unindexed repo or 401/403 → fall back to git-clone.

ast-grep

trancong12102/agentskills

Structural code tools via ast-grep — search by AST pattern, and outline file/module structure. Use when a search needs code structure that grep can't express (e.g. async functions containing await, calls with specific argument shapes), or when mapping a file's or directory's symbols, exports, and imports before reading it. Do not use for text search when plain grep or LSP suffices.

code-search

trancong12102/agentskills

Routes local codebase search to the right tool — keyword, semantic, or symbol. Use when searching a codebase for identifiers, tracing features across files, answering conceptual questions about local code, or exploring unfamiliar projects. Do not use for external docs, GitHub repos, or package lookups.

lib-docs

trancong12102/agentskills

Fetches library documentation from author-published llms.txt, with context7 as fallback. Use when looking up docs, API references, changelogs, or breaking changes for an external library or framework. Do not use for local code or repository source exploration.

pkg-versions

trancong12102/agentskills

Checks latest stable versions and deprecation status of public packages via deps.dev. Use when adding or updating dependencies, verifying whether a package is deprecated, or comparing installed versions against latest. Do not use for private registries or package documentation.
