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.
Master the four operations of context engineering — Write, Select, Compress, Isolate.

What it does
Context Engineering is an agent skill from rohitg00/pro-workflow. Master the four operations of context engineering — Write, Select, Compress, Isolate. Manage token budgets, compaction strategies, and context partitioning to keep AI sessions sharp and efficient.
Its SKILL.md is about 1.6k 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 and LLM cost and token optimization. The repository describes itself as: Claude Code learns from your corrections: self-correcting memory that compounds over 50+ sessions. Context engineering, parallel worktrees, agent teams, and 17 battle-tested…
When your agent uses it
- Tasks that involve Context engineering
- Tasks that involve LLM cost and token optimization
Example prompts
- “/context-engineering”
Workflow steps
4 steps, taken from the step headings in SKILL.md.
- Write — Persist Info Outside Context
- Select — Retrieve Relevant Info
- Compress — Reduce Tokens, Preserve Signal
- Isolate — Partition Across Execution Spaces
What it can do on your machine
Read from SKILL.md and the folder at commit 86d5f27. 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:
claude
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 Engineering loads about 1.6k tokens when it runs. Until then it costs about 54 tokens; SKILL.md has 623 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
Without a licence we can't republish the file, so here is its outline and opening line. It has 623 words (~1,607 tokens).
“Four operations control everything about how context flows through an AI coding session. Master them and you control the quality of every response.”

Questions about Context Engineering
What does Context Engineering do?
Master the four operations of context engineering — Write, Select, Compress, Isolate. Context Engineering is an agent skill from rohitg00/pro-workflow. Master the four operations of context engineering — Write, Select, Compress, Isolate.
When should I use Context Engineering?
Context Engineering fits situations like: tasks that involve Context engineering; tasks that involve LLM cost and token optimization.
How do I install Context Engineering in Claude Code?
Run `npx skills add rohitg00/pro-workflow --skill context-engineering -a claude-code`. Or copy the skill folder (skills/context-engineering in rohitg00/pro-workflow) into .claude/skills/context-engineering in your project. Claude Code loads it when a task matches its description.
How do I install Context Engineering in Codex?
Run `npx skills add rohitg00/pro-workflow --skill context-engineering -a codex`. Or copy the skill folder (skills/context-engineering in rohitg00/pro-workflow) into .agents/skills/context-engineering in your project. Codex loads it when a task matches its description.
Can I use Context Engineering in Cursor, Gemini CLI or GitHub Copilot?
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add rohitg00/pro-workflow --skill context-engineering -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/context-engineering, .gemini/skills/context-engineering, .github/skills/context-engineering and .opencode/skills/context-engineering in your project.
What does Context Engineering need to run?
Going by SKILL.md and its folder, Context Engineering needs the command-line tools its instructions call (claude).
Does Context Engineering access the network?
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
Is Context Engineering safe to install?

What licence does Context Engineering use?
No licence was found for Context Engineering or its repository. Without one, default copyright applies: ask the author before reusing or redistributing it.
How many tokens does Context Engineering use?
About 1.6k tokens (SKILL.md is roughly 6.4k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
