Summary

Fixes the remaining part of #1484.

.env.example describes MAX_OBS_PER_SESSION as a "cap before consolidation kicks in". Reaching it starts no consolidation: mem::observe refuses every further observation of that session with Session observation limit reached (N), and capture parks each one as a dead letter. 0 disables the cap.

Setting Before After
MAX_OBS_PER_SESSION "Per-session observation cap before consolidation kicks in" "Hard per-session cap: later observations of that session are refused and parked as dead letters (0 = no cap)"

The AGENTMEMORY_SLOTS half of #1484 is already corrected on main, so this PR now changes only the one line above.

Checks

  • Text checked against current main: the cap branch in mem::observe and the dead-letter path in capture
  • npm run build, npm run skills:gen, npm run docs:sync (no changes), npm run skills:check

Summary by CodeRabbit

  • Documentation
    • Clarified that the observation limit is a hard per-session cap: later observations are rejected and parked as dead letters. Set it to 0 for no cap.
    • Documented that editable memory slots are enabled only when the setting is exactly "true", replacing the previous comma-separated plugin slot names.

…ents

AGENTMEMORY_SLOTS was described as a comma-separated list of slot names, but
isSlotsEnabled() accepts only "true", so following the comment left slots
off while the .env looked configured. MAX_OBS_PER_SESSION was described as
a cap "before consolidation kicks in"; reaching it starts no consolidation,
mem::observe refuses every further observation of that session.

Walkthrough

The MAX_OBS_PER_SESSION comment now describes the hard per-session limit, what happens to later observations, and the meaning of 0.

Changes: Observation limit documentation

Layer / File(s) Summary
Clarify observation limit behavior
.env.example
The comment states that later observations are refused and parked as dead letters, and that 0 means no cap.

Estimated code review effort: 1 (Trivial) | ~5 minutes

Change: Other

Suggested reviewers: rohitg00

Merge Risk: Low · up to 339ab

The documentation correctly explains the observation cap, but overstates dead-letter handling for direct callers. This is a bounded wording issue suitable for follow-up and does not change runtime behavior.

Explanation

The title "docs(env): correct the MAX_OBS_PER_SESSION comment" matches the only change in the changeset, a one-line edit to the MAX_OBS_PER_SESSION comment in .env.example. It is specific, concise, and names the file scope and the changed setting. The objectives confirm the PR now changes only that comment, because main already fixed the AGENTMEMORY_SLOTS comment.

Full details: Linked Issues check

Explanation

[#1484] Whole-PR diff (merge base c6c476d to head 339abd7) changes one line in .env.example: the MAX_OBS_PER_SESSION comment. The new text says the cap is a hard per-session cap, that later observations of the session are refused and parked as dead letters, and that 0 means no cap. Source at head matches this text. In src/functions/observe.ts, the branch if (maxObservationsPerSession &amp;&amp; maxObservationsPerSession &gt; 0) returns Session observation limit reached (N) when existing.length &gt;= maxObservationsPerSession, so 0 disables the cap and reaching the cap does not start consolidation. The old comment, which said the cap came before consolidation, is removed. [#1484] The AGENTMEMORY_SLOTS line at head reads # AGENTMEMORY_SLOTS=true # Enable structured memory slots (default off). The example value is exactly true, and the comment names the feature. The old misleading AGENTMEMORY_SLOTS=memory text is gone. The comment does not use the words 'must be exactly true', which is a minor wording gap, not a conflict with isSlotsEnabled(). Not verified in this review: the dead-letter parking path in capture, which the comment also describes. The comment is documentation, so the coding-only check applies to the observe cap branch, which matches. No automated test was added or required for a comment-only change. The issue's docs:check and skills:check acceptance commands were not run in this review; the PR author reports them as passing.

Full details: Out of Scope Changes check

Explanation

The whole-PR diff against the merge base contains only the single-line change to the MAX_OBS_PER_SESSION comment in .env.example. This line is the objective of #1484 and the PR summary. No other file changed, so no out-of-scope change exists in the reviewed diff. The incremental change since the previous reviewed head (6cc59e3) is covered by the same whole-PR diff. The AGENTMEMORY_SLOTS line is unchanged from the base, which matches the PR statement that main already fixed it.
