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"

A test case the skill fixed. Same model, same prompt, with and without the skill.
I need to search the API documentation at https://api.stripe.com/v1/docs to find all query parameters supported by the charges endpoint. How should this web page be processed?
| Checked | Without skill | With skill |
|---|---|---|
| Calls `ctx_fetch_and_index` for the Stripe documentation URL. | Missed | Passed |
| Calls `ctx_search` to locate charges endpoint parameters. | Missed | Passed |
The instructions your model reads when the skill loads.
context-mode MCP tools are available in GitHub Copilot CLI. These rules protect the context window from flooding — one unrouted command can dump tens of KB into the conversation. Follow them strictly.
Analyze / count / filter / compare / search / parse / transform data: write
code via ctx_execute(language, code) and console.log() only the answer. Do
NOT read raw data into context. PROGRAM the analysis, do not COMPUTE it by
reading. One script replaces ten tool calls.
ctx_fetch_and_index(url, source) then ctx_search(queries).node -e "fetch(...)", python -c "requests.get(...)") — use
ctx_execute(language, code); only stdout enters context.ctx_execute_file(path, language, code).ctx_batch_execute(commands, queries) — runs all commands,
auto-indexes, returns search. One call replaces dozens.ctx_execute / ctx_execute_file — sandbox; only stdout enters
context.ctx_fetch_and_index(url, source) then ctx_search(queries) — raw
HTML never enters context.ctx_search(queries: [...]) — all questions in one call.Write artifacts to FILES; return a path + one-line description, not inline dumps.
