 **Observed LAW 4 violation (2026-04-18, Peter Steinberger disaster #2):** the model emitted `Headline`, `What he is actually saying`, `Cross-source corroboration`, `Where evidence is thin`, `Bottom line` on a GENERAL query. The narrative shape for person topics is `What I learned:` + bold-lead-in paragraphs + prose label `KEY PATTERNS from the research:` + numbered list. No blog-post subheadings.

You MUST include that block verbatim in your synthesis, positioned after KEY PATTERNS (and after the comparison-table scaffold if present) and before the invitation.

+**LAW 5 - ENGINE FOOTER PASS-THROUGH. EVERY QUERY TYPE. EVERY RUN.** The engine output ends with a `✅ All agents reported back!` emoji-tree footer bounded by `---` lines and wrapped in `<!-- PASS-THROUGH FOOTER -->` / `<!-- END PASS-THROUGH FOOTER -->` comments (v3.0.10+). You MUST include that block verbatim in your synthesis, positioned after KEY PATTERNS (and after the comparison-table scaffold if present) and before the invitation. Do not recompute the stats, reformat the tree, paraphrase, skip it, or fabricate your own `## Notable Stats` replacement. A response without the engine footer is not valid skill output.
+
+**LAW 6 - NO RAW RANKED EVIDENCE CLUSTERS IN BODY.** The engine's `## Ranked Evidence Clusters`, `## Stats`, and `## Source Coverage` blocks are bounded inside `<!-- EVIDENCE FOR SYNTHESIS -->` / `<!-- END EVIDENCE FOR SYNTHESIS -->` comments in the `--emit compact` / `--emit md` stdout. They are raw evidence for YOU to read, not output to emit. Transform them into `What I learned:` prose paragraphs per LAW 2 (or the COMPARISON template sections per the LAW 4 exception). If your response contains the literal string `### 1.` followed by a score tuple like `(score N, M items, sources: ...)`, or the string `- Uncertainty: single-source` / `- Uncertainty: thin-evidence`, you dumped evidence instead of synthesizing. STOP and regenerate.
+
+**Observed LAW 6 violation (2026-04-19, Hermes Agent Use Cases disaster):** two consecutive `/last30days Hermes Agent (Actual) Use Cases` runs returned the raw `## Ranked Evidence Clusters` block verbatim as user output, with 8 cluster entries carrying `(score N, M items, sources: ...)` tuples and `- Uncertainty: single-source` lines. Root cause: the prior canonical-boundary text said "Pass through the lines ABOVE this boundary verbatim," which the model scoped broadly to include the scratchpad. The current boundary text and this LAW 6 scope pass-through to the PASS-THROUGH FOOTER block only. A third run on the same topic framed as "Hermes Workflows" produced the correct `What I learned:` prose synthesis, which is the shape every run must produce.
+
+**Worked example (LAW 6 transformation).** Evidence block you read:
+
+```

+The self-evolving loop is the sticky use case. Every 15 tool calls Hermes pauses, self-evaluates, and writes a Skill Document from what worked. Prompt Engineering's 11K-view walkthrough frames this as the real differentiator: "every 15 tool calls, the agent kind of pauses, and then it does self-evaluation."
+
+Cron-scheduled autonomous briefings are the most-cited concrete workflow. r/TunisiaTech's "Use cases of OpenClaw, Hermes Agent" thread says it plainly: "Currently I have daily cron jobs for news briefing, but I know there's much more I can do."
+```
+
+**LAW 7 - YOU ARE THE PLANNER. `--plan` IS MANDATORY ON NAMED-ENTITY TOPICS.** If you are the reasoning model hosting this skill (Claude Code, Codex, Hermes, Gemini, or any agent runtime that invoked `/last30days`), YOU generate the JSON query plan. You do not need an API key, "LLM provider" credentials, or an external planning service - you ARE the LLM. The `--plan` flag exists precisely so a reasoning model generates its own plan upstream and passes it to the engine. The engine's internal planner and deterministic fallback are headless/cron paths only; on any reasoning-model path, bypass them by passing `--plan '$JSON'`.
+
+Named-entity topics (capitalized proper nouns, product names, person names, project names, or any topic that would benefit from handle resolution in Step 0.55) REQUIRE `--plan`. Your invocation of `scripts/last30days.py` MUST contain `--plan '$JSON'`. A bare `python3 scripts/last30days.py "$TOPIC" --emit=compact` on a named-entity topic is a LAW 7 violation. Before you invoke Bash, self-check: does my command contain `--plan`? If no, STOP and generate a plan first (see Step 0.75 for the schema).
+
+**Observed LAW 7 violation (2026-04-19, Hermes Agent Use Cases Run 1):** the model called the engine bare with no `--plan`, no pre-flight handle resolution. The engine emitted a stderr warning ("No --plan and no LLM provider configured. Using deterministic fallback...") which the model read as a capability constraint ("I don't have a key, I can't do LLM stuff") instead of as what it actually was: a reminder that the reasoning model skipped its own planning step. The misread came from the word "provider" - the engine uses "provider" to mean "the key for the engine's INTERNAL planner," but the model parsed it as "I need a provider to plan at all." You do not. You ARE the provider. Run 2 of the same topic (2026-04-19, framed as "best workflows") with the same model and same cache generated the plan itself via `--plan` and produced clean results - the delta was this step.
+
+**Self-check before Bash:** re-read your pending `scripts/last30days.py` command. Does it contain `--plan '$JSON'`? If no, and the topic is a named entity, STOP. Return to Step 0.75 and generate the plan. Do not interpret the word "provider" in any engine message as "you need credentials" - you are the provider.
 
 End of OUTPUT CONTRACT. The laws above are the contract; everything below is implementation detail.
