Computer programmer and IT specialist from Türkiye. I build small, sharp developer tools:
MCP servers for AI agents and CLIs that catch problems before they ship.
| Project | Language | What it does |
|---|---|---|
| aichurn |  |
Does AI-written code get rewritten faster? Replays git history line by line: two-week churn, copy/paste and moved code, split by AI-assisted vs human commits. Ran on 13 popular repos. Single binary. |
| agentprs |  |
How do AI agents' pull requests fare in your repo? Share, merge rate and time to merge for Copilot, Claude Code, Codex, Cursor, Devin, Jules and 8 more, next to human PRs. GitHub Action, SVG card + badge. |
| aiblame |  |
How much of this repo did AI write? git blame for the agent era: the share of today's code written with Claude Code, Cursor, Copilot, Codex, Aider, Devin and 9 more. Works on any GitHub repo, SVG card + badge, CI gate. Zero dependencies. |
| shush | |
Compresses noisy command output (test runs, installs, builds) before it reaches an AI agent. Errors are always kept. ~69% fewer tokens on a real benchmark. MCP server + CLI. |
| turkiye-mcp | |
MCP server with 17 Türkiye-specific tools: TCMB exchange rates, earthquakes, holidays and business days, IBAN/TCKN/VKN validation, provinces, prayer times, weather. No API keys. |
| lockdiff | |
Readable diffs for lockfiles: upgraded, downgraded, added and removed packages with major bumps first. 10 formats (npm, pnpm, yarn, Cargo, Go, Poetry, uv, ...), Markdown for PR comments. |
| csvglance | |
Profiles a CSV in one streaming pass: types, missing values, distinct counts (HyperLogLog), ranges and top values per column. Detects delimiters, gzip, decimal commas. ~1 s per million rows. |
| todoage | |
How old are your TODOs? Uses git blame to show who wrote each TODO/FIXME and when, oldest first, with a CI gate for stale ones. |
| certpeek | |
Checks TLS certificates for one host or hundreds: expiry, hostname, trust chain, TLS version. JSON output and exit codes for cron/CI. |
| envguard |  |
Linter for .env files: syntax errors, duplicates, keys missing from .env.example, and real secrets committed by mistake. pre-commit hook included. |
| turkcekit | |
Turkish text done right in Python: correct İ/ı casing, URL slugs, Turkish alphabetical sorting, numbers and lira amounts in words, 1.234,50 ₺ formatting. Zero dependencies, CLI included. |
| llmslint | |
Linter for llms.txt, the file that points AI agents at your docs: structure, link format, relative and dead URLs, size of the Optional section. Works on a file, URL or whole domain; JSON and CI modes. |
| skillcheck | |
Linter for Agent Skills, the SKILL.md folders that Claude Code, Codex, Cursor and Copilot load on demand: name and description rules, strict frontmatter with line numbers, broken file links, context-size warnings. Zero dependencies; JSON and GitHub annotation output. |
| tokmap | |
See where your repo's tokens go before an AI agent reads it: a token budget map of files and folders, flags lockfiles, minified bundles, generated code and snapshots, and a --budget CI check. Single binary, zero dependencies. |
| awesome-turkiye-dev |  |
Curated resources for developers in Türkiye: open-source projects, Turkish NLP, APIs and open data, communities, events and jobs. |
Every project is MIT-licensed, has CI on every push, and ships with real example output in its README.
