What it does
Use context-mode tools (ctx_execute, ctx_execute_file) instead of Bash/cat when processing large outputs. Triggers: "analyze logs", "summarize output", "process data", "parse JSON", "filter results", "extract errors", "check build output", "analyze dependencies", "process API response", "large file analysis", "page snapshot", "browser snapshot", "DOM structure", "inspect page", "accessibility tree", "Playwright snapshot", "run tests", "test output", "coverage report", "git log", "recent commits", "diff between branches", "list containers", "pod status", "disk usage", "fetch docs", "API reference", "index documentation", "call API", "check response", "query results", "find TODOs", "count lines", "codebase statistics", "security audit", "outdated packages", "dependency tree", "cloud resources", "CI/CD output". Also triggers on ANY MCP tool output that may exceed 20 lines. Subagent routing is handled automatically via PreToolUse hook.
Context Mode: Default for All Large Output
MANDATORY RULE
<context_mode_logic> <mandatory_rule> Default to context-mode for ALL commands. Only use Bash for guaranteed-small-output operations. </mandatory_rule> </context_mode_logic>
Bash whitelist (safe to run directly):
- File mutations:
mkdir,mv,cp,rm,touch,chmod - Git writes:
git add,git commit,git push,git checkout,git branch,git merge - Navigation:
cd,pwd,which - Process control:
kill,pkill - Package management:
npm install,npm publish,pip install - Simple output:
echo,printf
Everything else → ctx_execute or ctx_execute_file. Any command that reads, queries, fetches, lists, logs, tests, builds, diffs, inspects, or calls an external service. This includes ALL CLIs (gh, aws, kubectl, docker, terraform, wrangler, fly, heroku, gcloud, etc.), there are thousands and we cannot list them all.
When uncertain, use context-mode. Every KB of unnecessary context reduces the quality and speed of the entire session.
