Context Mode Output Sandbox
mksglu/context-mode
Routes large command, file, API and browser output through context-mode tools so only the needed result enters the agent's context, instead of dumping it via Bash.
Keep the agent's context lean so accuracy doesn't collapse. An agent skill from Archive228/loopkit.

What it does
Context Budget is an agent skill from Archive228/loopkit. Keep the agent's context lean so accuracy doesn't collapse. Use on long sessions, big files, or when the agent starts hallucinating.
Its SKILL.md is about 240 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Agent Workflows, covering Context engineering. The repository describes itself as: 33 battle-tested skills + minimal .claude harness for any coding agent (Claude Code, Cursor, Codex, Gemini CLI). The licence is MIT.
When your agent uses it
- Tasks that involve Context engineering
Example prompts
- “s context lean so accuracy doesn”
- “/context-budget”
What it can do on your machine
Read from SKILL.md and the folder at commit 5ae033e. 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
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
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 Budget loads about 241 tokens when it runs. Until then it costs about 37 tokens; SKILL.md has 106 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.
SKILL.md

- long session, huge file dump, agent forgetting earlier steps, accuracy dropping
Context Budget
More context is not better. Past a threshold, accuracy falls off a cliff (context rot).
- Don't dump whole files — read the relevant function/section, not the 2000-line module.
- Summarize, don't accumulate — replace a 200K-token transcript with a 4K recap of the load-bearing facts.
- Drop dead context — once a sub-task is done, its detail leaves the window. Keep the decision, drop the trace.
- State on disk, not in context — progress goes to a file the next turn re-reads, not into an ever-growing prompt. A bloated standing context (CLAUDE.md) taxes every single turn. Trim weekly. If the agent is confidently wrong, suspect the context before the model.
