At a glance
Rules for sending data-heavy work through context-mode's sandboxed MCP tools so raw output, web pages and large files stay out of the context window.
- Works in 4 steps: GATHER: ctx_batch_execute(commands,… → PROCESS: ctx_execute / ctx_execute_file… → WEB: ctx_fetch_and_index(url, source)… → …
- Analyzing a large log, CSV or API response without flooding the context window
- SKILL.md covers Think in Code — MANDATORY, BLOCKED — do NOT use and Tool selection
- Calls node and python
What it does
This short rule set is meant for GitHub Copilot CLI with the context-mode MCP tools installed. Its main principle is to write code for any analysis instead of reading data: to count, filter, compare, search, parse or transform, the agent runs a script through ctx_execute and prints only the answer, rather than loading raw data into the conversation.
It blocks curl and wget, inline HTTP calls made from node or python, and reading large files just to analyze them. In their place it names ctx_fetch_and_index followed by ctx_search for web content, ctx_execute_file for files, ctx_batch_execute to run several commands and search them in one call, and ctx_search with all questions batched. Artifacts are written to files and reported as a path with a one-line description.
When your agent uses it
- Analyzing a large log, CSV or API response without flooding the context window
- Fetching and searching a web page while keeping raw HTML out of the conversation
- Running several data-heavy shell commands in one batched call
Example prompts
- “Count the distinct error codes in logs/app.log and show me only the totals.”
- “Fetch the release notes page and answer which version dropped Node 18 support.”
- “Compare the two JSON exports in exports/ and list only the differing keys.”
Requirements
- The context-mode MCP server and its ctx tools
- GitHub Copilot CLI
Workflow steps
4 steps, taken from the first numbered list in SKILL.md.
- GATHER: ctx_batch_execute(commands, queries) — runs all commands,
- PROCESS: ctx_execute / ctx_execute_file — sandbox; only stdout enters
- WEB: ctx_fetch_and_index(url, source) then ctx_search(queries) — raw
- SEARCH: ctx_search(queries: [...]) — all questions in one call.
What it can do on your machine
Read from SKILL.md and the folder at commit 2a7a92a. 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:
nodepython
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 Mode Routing Rules loads about 425 tokens when it runs. Until then it costs about 57 tokens; SKILL.md has 175 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
Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 175 words (~425 tokens).
“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.”
