What it does
Context Shunt is an agent skill from alinaqi/maggy. Offload large / multi-file reads to a cheap worker model so raw files never enter Claude's context (token savings)
Its SKILL.md is about 560 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
The repository describes itself as: What started as an opinionated Claude Code setup kit is now an autonomous AI engineering command center. The licence is MIT.
Example prompts
- “/context-shunt”
What it can do on your machine
Read from SKILL.md and the folder at commit 72a456e. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
git
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md. Its commands use git, which can reach the network depending on how they are called.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Context Shunt loads about 564 tokens when it runs. Until then it costs about 32 tokens; SKILL.md has 231 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Context Shunt — Read Cheap, Keep Context Small
Reading big files into context is the most expensive thing an agent does for the
least reasoning value. The shunt hands those reads to a cheap worker model
(bulk-read) that answers a question about the files and returns a compact
summary. The raw bytes never enter this session's context.
This is orthogonal to whole-turn routing (srooter / route-task): those pick the
model for the turn; the shunt trims what a tool call pulls into context when
the turn is legitimately here.
Decision: read raw, shunt, or graph?
- Editing this exact file — read it raw. You need every line; never edit against a summary.
- A fact/answer across large or many files —
bulk-read "<question>" file.... - A code symbol (function/class/route) —
get_code_snippet(qualified_name): free and exact. - Small file (under threshold) you need in full — read it raw.
A shunt answer is for understanding, not for producing a diff.
Usage
bulk-read "how does token refresh work?" src/auth/session.ts src/auth/refresh.ts
bulk-read "which config keys are read at startup?" $(git ls-files 'config/*.yaml')bulk-read prints structured bullets citing path:line, or
NOT FOUND IN PROVIDED FILES. A token-savings report goes to stderr.
Configuration
Env vars or ~/.claude/shunt.conf (see templates/shunt.conf):
SHUNT—on/offmaster switch for the PreToolUse hook.SHUNT_MIN_LINES— large-read threshold (default 350).SHUNT_MODE—suggest(default) /block/offfor the hook's large-read action.SHUNT_GRAPH_NUDGE—on/offonce-per-session graph nudge.SHUNT_MODEL— worker command (defaultdeepseek --flash; alsogemini-api --flash-lite,qwen3,glm).
The context-shunt-gate PreToolUse hook enforces the thresholds; this skill tells
you when to reach for bulk-read yourself.

Questions about Context Shunt
What does Context Shunt do?
Offload large / multi-file reads to a cheap worker model so raw files never enter Claude's context (token savings). Context Shunt is an agent skill from alinaqi/maggy.
How do I install Context Shunt in Claude Code?
Run `npx skills add alinaqi/maggy --skill context-shunt -a claude-code`. Or copy the skill folder (skills/context-shunt in alinaqi/maggy) into .claude/skills/context-shunt in your project. Claude Code loads it when a task matches its description.
How do I install Context Shunt in Codex?
Run `npx skills add alinaqi/maggy --skill context-shunt -a codex`. Or copy the skill folder (skills/context-shunt in alinaqi/maggy) into .agents/skills/context-shunt in your project. Codex loads it when a task matches its description.
Can I use Context Shunt in Cursor, Gemini CLI or GitHub Copilot?
