# Context routing: stop giving coding agents memory by default

**[AI](https://daily.dev/sources/ai)** · [@danmercede](https://daily.dev/danmercede) · 1 min read · 4 upvotes · 0 comments

## Summary

Most coding-agent setups inject all available context by default — repo, wiki, long-term memory, RAG, MCP tools — leading to slower, noisier, less reliable sessions. An alternative pattern called evidence-gated context routing proposes that context must earn admission before being injected into an agent session. Each candidate context source is evaluated against criteria: is it allowed for this task, is it fresh enough, has it passed quality gates and smoke tests? This approach replaces default memory injection with read-only recall, explicit tool allow-lists, registry freshness checks, and quality-gated cache proposals. The goal is to turn memory from a passive default into a controlled, trusted input surface that reduces token bloat and state noise.

Most coding-agent setups treat context like free infrastructure:

- load the repo
- load the wiki
- load long-term memory
- load RAG
- load every MCP/tool surface

then wonder why the session gets slower, noisier, or less reliable

I’ve been testing the opposite pattern:

Evidence-gated context routing.

The agent starts with the task. Candidate context has to earn admission before it gets injected:

1. Allowed for this task?
2. Fresh enough?
3. Passed an offline quality gate?
4. Passed smoke tests?

If yes, route it in.

If no, keep it out.

The useful pattern was not “more memory.” It was:

- read-only recall
- explicit tool allow-lists
- registry freshness checks
- cache proposals behind quality gates
- semantic replay quarantined from coding, governance, incident, and current-state answers until it earns trust

Default context injection creates token bloat and noisy state.

Context routing turns memory into a controlled input surface.

Curious how others are handling this:

Are you gating agent memory and MCP/tool context today, or mostly measuring token count after the fact?
