A Claude Code plugin that checks if your project idea already exists on GitHub before you build it.
🟢 No close match
🟡 Adjacent prior art — worth a closer look
🔴 Strong overlap — someone has likely shipped this
Run these inside the Claude Code chat.
/plugin marketplace add suleman-dawood/reporecon
/plugin install reporecon@reporecon
Fully quit and reopen Claude Code so the plugin registers (not /clear
— actually close the app process).

/reporecon I want to build a CLI that previews diffs as a side-by-side TUI
Or just describe an idea naturally in chat:
"is there already a tool that does X""validate my idea before I start building""does this exist on github"
You get a verdict in ~90 seconds. If it's 🟡 or 🔴, reply deep search
(or yes
/ dig deeper
) to clone the top candidates and get file-path-cited evidence (~10 min).
Reports land in ./reporecon-reports/YYYY-MM-DD-<slug>.md
. One file per idea.
A chat verdict block like this:
🟡 Some overlap — worth a closer look
Your idea: "side-by-side TUI diff previewer with syntax highlighting"
Top match: dandavison/delta (28k★, active) — WORTH_INSPECTING
Reply 'deep search' to clone the top candidates and judge
with file-path evidence (~10 min).
Report: ./reporecon-reports/2026-05-27-tui-diff-previewer.md
The on-disk report has the full per-candidate breakdown, axis scores, and — after a deep search — cited evidence by path/file.ext:LINE
.
If /reporecon
doesn't seem to do anything after install:
- Confirm the plugin shows up: type
/plugin
in chat - Try the natural-language trigger ("does this exist on github") — bypasses slash-command routing
/plugin uninstall reporecon
→/plugin install reporecon@reporecon
→fully restart Claude Code(close the app, not/clear
)
GitHub-only. GitLab, Codeberg, self-hosted forges, and package-registry-only tools are not searched.WebSearch results drift. Same query on different days can shift the verdict on borderline ideas.Verify before you decide. RepoRecon narrows the search; it doesn't replace you making the final call yourself before you commit to a project.
