+description: Evidence-first live messaging workflow for ECC. Use when the user wants to read texts or DMs, recover a recent one-time code, inspect a thread before replying, or prove which message source was actually checked.
+origin: ECC
+---
+
+# Messages Ops
+
+Use this when the task is live-message retrieval: iMessage, DMs, recent one-time codes, or thread inspection before a follow-up.
+
+This is not email work. If the dominant surface is a mailbox, use `email-ops`.
+
+## Skill Stack
+
+Pull these ECC-native skills into the workflow when relevant:
+
+- `email-ops` when the message task is really mailbox work
+- `connections-optimizer` when the DM thread belongs to outbound network work
+- `lead-intelligence` when the live thread should inform targeting or warm-path outreach
+- `knowledge-ops` when the thread contents need to be captured into durable context
+
+## When to Use
+
+- user says "read my messages", "check texts", "look in DMs", or "find the code"
+- the task depends on a live thread or a recent code delivered to a local messaging surface
+- the user wants proof of which source or thread was inspected
+
+## Guardrails
+
+- resolve the source first:
+  - local messages
+  - X / social DM
+  - another browser-gated message surface
+- do not claim a thread was checked without naming the source
+- do not improvise raw database access if a checked helper or standard path exists
+- if auth or MFA blocks the surface, report the exact blocker
+
+## Workflow
+
+### 1. Resolve the exact thread
+
+Before doing anything else, settle:
+
+- message surface
+- sender / recipient / service
+- time window
+- whether the task is retrieval, inspection, or prep for a reply
+
+### 2. Read before drafting
+
+If the task may turn into an outbound follow-up:
+
+- read the latest inbound
+- identify the open loop
+- then hand off to the correct outbound skill if needed
+
+### 3. Handle codes as a focused retrieval task
+
+For one-time codes:
+
+- search the recent local message window first
+- narrow by service or sender when possible
+- stop once the code is found or the focused search is exhausted
+
+### 4. Report exact evidence
+
+Return:
+
+- source used
+- thread or sender when possible
+- time window
+- exact status:
+  - read
+  - code-found
+  - blocked
+  - awaiting reply draft
+
+## Output Format
+
+```text
+SOURCE
+- message surface
+- sender / thread / service
+
+RESULT
+- message summary or code
+- time window
+
+STATUS
+- read / code-found / blocked / awaiting reply draft
+```
+
+## Pitfalls
+
+- do not blur mailbox work and DM/text work
+- do not claim retrieval without naming the source
+- do not burn time on broad searches when the ask is a recent-code lookup
+- do not keep retrying a blocked auth path without surfacing the blocker
+
+## Verification
+
+- the response names the message source
+- the response includes a sender, service, thread, or clear blocker
+- the final state is explicit and bounded
