What Sift does
A context budget for CI. The bundle-size bot, for agent configuration — measures the always-on context tax of your CLAUDE.md, skills and subagents, diffs it per pull request, and fails the build when it grows.

README
Sift
**A context budget for CI.** The bundle-size bot, for agent configuration.
[](https://github.com/Jithendrag22/sift/actions/workflows/tests.yml) [](LICENSE) [](#requirements) [](#requirements)
Your `CLAUDE.md`, your skills, your subagents load into **every session, for every engineer, on every task**. Nobody is watching the total.
Sift puts the number on the pull request that moved it.
### ❌ Context budget — FAIL
████████████████████████████ 2,534 / 1,000 always-on tokens (253%)
+2,469 always-on tokens vs base.
That prefix is cache-written once at 2× and re-read at 0.1× on each of ~45 turns,
so it bills as +15,801 input tokens per session (×6.4).
| file | kind | was | now | Δ |
|--------------------------------------------|--------------|-----:|-----:|-------:|
| CLAUDE.md | instructions | 23 | 1908 | +1,885 |
| .claude/skills/changelog-writer/SKILL.md | skill | 0 | 118 | +118 |
Why
Agent configuration grows the way dependency trees grow: one reasonable addition at a time, each individually defensible, nobody watching the total.
JavaScript did not solve bundle bloat by being clever. It solved it **socially** — by putting the number on the pull request that caused it, while someone could still change their mind. Agent configuration has no such number.
And the cost is not only money:
| source | finding |
|---|---|
| Anthropic, Tool Search Tool | Cutting always-loaded tool definitions from ~77K to ~8.7K tokens raised MCP accuracy 49% → 74% (Opus 4) and **79.5 |
