How I cut AI context tokens by 80%

Token is the new currency.

CodePulse to solve a frustrating problem: every time I start an AI coding session, I waste hundreds of tokens just explaining what my project is, where things live, and what files are relevant.

CodePulse indexes your repo into SQLite and serves a smart context snapshot — only what the AI needs, nothing it doesn't.

What it does:

Extracts symbols (functions, classes, exports) via Tree-Sitter AST parsing
Scores file relevance against your task using keyword matching on paths, summaries, and symbol names
Tracks which files change most often (git history) and surfaces hot files first
Auto-scales the token budget to repo size (skips tiny repos, scales up to 4k tokens for large ones)
Keeps itself fresh with a git post-commit hook installer

Token savings in practice:

On a medium-sized TypeScript project: manual context pasting = ~6,000 tokens. CodePulse = ~800 tokens, with better coverage because it
prioritizes relevant files.

Three ways to use it:

Claude Code skill (recommended) — drops a skill/codepulse/ folder in your project, auto-injects context on every prompt
CLI — codepulse context --task "fix the login bug" | pbcopy
MCP server — for tools that support Model Context Protocol

Install:
npm install -g @aicodepulse/cli
codepulse index .
codepulse context --task "your task here"

Would love feedback on the scoring algorithm, the token budget tiers, and whether the MCP integration is worth investing more in. Source is on GitHub.

Job hunting is brutal enough without paying $30/month just to have your resume "analyzed."

So I built one myself, powered by AI, and I'm keeping it free as long as I can afford the API costs.

Here's what it does:

Uploads your resume (PDF, DOCX, or TXT)
Scores it against ATS systems — the software that filters your resume before a human ever sees it
Gives you specific, actionable suggestions based on the actual job description you paste in
Exports a clean, ATS-compatible PDF in one click

What it does NOT do:

Require an account or login of any kind
Charge you anything
Track you, sell your data, or store your resume
Ask for your email

You paste your resume, you paste the job description, you get your score and improvements. That's it. No funnel, no upsell, no dark patterns.

I'm running this on my own dime. If it ever goes down, that's just the AWS bill hitting. Enjoy it while it lasts.
