# context-mode — MANDATORY routing rules

You have context-mode MCP tools available. These rules are NOT optional — they protect your context window from flooding. A single unrouted command can dump 56 KB into context and waste the entire session.

## BLOCKED commands — do NOT attempt these

### curl / wget — BLOCKED
Any Bash command containing `curl` or `wget` is intercepted and replaced with an error message. Do NOT retry.
Instead use:
- `ctx_fetch_and_index(url, source)` to fetch and index web pages
- `ctx_execute(language: "javascript", code: "const r = await fetch(...)")` to run HTTP calls in sandbox

### Inline HTTP — BLOCKED
Any Bash command containing `fetch('http`, `requests.get(`, `requests.post(`, `http.get(`, or `http.request(` is intercepted and replaced with an error message. Do NOT retry with Bash.
Instead use:
- `ctx_execute(language, code)` to run HTTP calls in sandbox — only stdout enters context

### WebFetch — BLOCKED
WebFetch calls are denied entirely. The URL is extracted and you are told to use `ctx_fetch_and_index` instead.
Instead use:
- `ctx_fetch_and_index(url, source)` then `ctx_search(queries)` to query the indexed content

## REDIRECTED tools — use sandbox equivalents

### Bash (>20 lines output)
Bash is ONLY for: `git`, `mkdir`, `rm`, `mv`, `cd`, `ls`, `npm install`, `pip install`, and other short-output commands.
For everything else, use:
- `ctx_batch_execute(commands, queries)` — run multiple commands + search in ONE call
- `ctx_execute(language: "shell", code: "...")` — run in sandbox, only stdout enters context

### Read (for analysis)
If you are reading a file to **Edit** it → Read is correct (Edit needs content in context).
If you are reading to **analyze, explore, or summarize** → use `ctx_execute_file(path, language, code)` instead. Only your printed summary enters context. The raw file content stays in the sandbox.

### Grep (large results)
Grep results can flood context. Use `ctx_execute(language: "shell", code: "grep ...")` to run searches in sandbox. Only your printed summary enters context.

## Tool selection hierarchy

1. **GATHER**: `ctx_batch_execute(commands, queries)` — Primary tool. Runs all commands, auto-indexes output, returns search results. ONE call replaces 30+ individual calls.
2. **FOLLOW-UP**: `ctx_search(queries: ["q1", "q2", ...])` — Query indexed content. Pass ALL questions as array in ONE call.
3. **PROCESSING**: `ctx_execute(language, code)` | `ctx_execute_file(path, language, code)` — Sandbox execution. Only stdout enters context.
4. **WEB**: `ctx_fetch_and_index(url, source)` then `ctx_search(queries)` — Fetch, chunk, index, query. Raw HTML never enters context.
5. **INDEX**: `ctx_index(content, source)` — Store content in FTS5 knowledge base for later search.

## Subagent routing

When spawning subagents (Agent/Task tool), the routing block is automatically injected into their prompt. Bash-type subagents are upgraded to general-purpose so they have access to MCP tools. You do NOT need to manually instruct subagents about context-mode.

## Output constraints

- Keep responses under 500 words.
- Write artifacts (code, configs, PRDs) to FILES — never return them as inline text. Return only: file path + 1-line description.
- When indexing content, use descriptive source labels so others can `ctx_search(source: "label")` later.

## ctx commands

| Command | Action |
|---------|--------|
| `ctx stats` | Call the `ctx_stats` MCP tool and display the full output verbatim |
| `ctx doctor` | Call the `ctx_doctor` MCP tool, run the returned shell command, display as checklist |
| `ctx upgrade` | Call the `ctx_upgrade` MCP tool, run the returned shell command, display as checklist |

## Beads Issue Tracker

This project uses **bd (beads)** for issue tracking. Run `bd prime` to see full workflow context and commands.

### Quick Reference

```bash
bd ready              # Find available work
bd show <id>          # View issue details
bd update <id> --claim  # Claim work
bd close <id>         # Complete work
```

### Rules

- Use `bd` for ALL task tracking — do NOT use TodoWrite, TaskCreate, or markdown TODO lists
- Run `bd prime` for detailed command reference and session close protocol
- Use `bd remember` for persistent knowledge — do NOT use MEMORY.md files

**Architecture in one line:** issues live in a local Dolt DB; sync uses `refs/dolt/data` on your git remote; `.beads/issues.jsonl` is a passive export. See https://github.com/gastownhall/beads/blob/main/docs/SYNC_CONCEPTS.md for details and anti-patterns.

## Session Completion

**When ending a work session**, you MUST complete ALL steps below. Work is NOT complete until `git push` succeeds.

**MANDATORY WORKFLOW:**

1. **File issues for remaining work** - Create issues for anything that needs follow-up
2. **Run quality gates** (if code changed) - Tests, linters, builds
3. **Update issue status** - Close finished work, update in-progress items
4. **PUSH TO REMOTE** - This is MANDATORY:
   ```bash
   git pull --rebase
   git push
   git status  # MUST show "up to date with origin"
   ```
5. **Clean up** - Clear stashes, prune remote branches
6. **Verify** - All changes committed AND pushed
7. **Hand off** - Provide context for next session

**CRITICAL RULES:**
- Work is NOT complete until `git push` succeeds
- NEVER stop before pushing - that leaves work stranded locally
- NEVER say "ready to push when you are" - YOU must push
- If push fails, resolve and retry until it succeeds
