# Flat File Context Progress Review and Quick Wins

## Progress so far
- Step 2 context: implemented (website analysis fast path + fallback).
- Step 3 context: implemented (research preferences + competitors fast path + fallback).
- Step 4 context: implemented (persona data fast path + fallback).
- Step 5 context: implemented (integrations fast path + fallback).
- Security baseline: user isolation checks, redaction, atomic writes, file-permission hardening.
- Size governance: payload budget + deterministic trimming + trim metadata.
- Internal linking: related-document links + manifest index.

## Quick-win improvements (next 1-2 sprints)
1. Add explicit TTL/staleness fields and auto-refresh hints per step.
2. Add lightweight checksums per section to detect DB drift quickly.
3. Add optional `.json.gz` companion for oversized archives.
4. Add shared reader utility for summary-first + selective field loading.
5. Add minimal unit tests for:
   - redaction
   - trimming behavior
   - manifest linking
   - cross-user load rejection
6. Add agent telemetry: record which sections are actually read to optimize summaries.


## Newly added agent tooling
- txtai agent tools for flat-file context manifest/read/write-note operations were added to SIF base agent to support file operations in agent workflows.
