# STEP 0: STALE-CLONE SELF-CHECK — RUN BEFORE READING BELOW

Before reading anything else in this file, check whether you loaded SKILL.md from the one known stale-clone location: Claude Code's marketplaces directory.

**Run this check:**

```bash
CLAUDE_CACHE_LATEST=$(find "$HOME/.claude/plugins/cache/last30days-skill/last30days" -mindepth 1 -maxdepth 1 -type d 2>/dev/null | sort -V | tail -1)
# Two cache layouts ship in the wild — nested ({version}/skills/last30days/SKILL.md)
# and flat ({version}/SKILL.md). Resolve to whichever shape actually exists.
CLAUDE_CACHE_SKILL_MD=""
if [ -n "$CLAUDE_CACHE_LATEST" ]; then
  if [ -f "$CLAUDE_CACHE_LATEST/skills/last30days/SKILL.md" ]; then
    CLAUDE_CACHE_SKILL_MD="$CLAUDE_CACHE_LATEST/skills/last30days/SKILL.md"
  elif [ -f "$CLAUDE_CACHE_LATEST/SKILL.md" ]; then
    CLAUDE_CACHE_SKILL_MD="$CLAUDE_CACHE_LATEST/SKILL.md"
  fi
fi
echo "CLAUDE_CACHE_SKILL_MD=$CLAUDE_CACHE_SKILL_MD"
```

If the SKILL.md path you just Read contains `/.claude/plugins/marketplaces/` AND `$CLAUDE_CACHE_SKILL_MD` is non-empty, STOP and re-read `$CLAUDE_CACHE_SKILL_MD` before proceeding. Otherwise the SKILL.md you have is fine — continue.

**Why this specific check:** `~/.claude/plugins/marketplaces/last30days-skill/` is a git clone Claude Code auto-restores to `origin/main` on session start. It can lag the versioned cache by one or more releases. Three 2026-04-22 test runs (Linear, Coinbase) loaded SKILL.md from `marketplaces/`, ran `--help` from the same stale path, did not see the `--competitors` flag that existed in the cache, and fell back to a manual comparison plan. Result: 2 of 3 windows never invoked the feature they were asked to test. STEP 0 defends against that one Claude Code-specific bug.

**Other install paths are fine:** `~/.codex/skills/`, `~/.agents/skills/`, an `npx skills add` install dir, or a repo checkout are all valid load points - the resolver in Step 1 picks them up. Do NOT abort or hop on those paths.

# SKILL CONTRACT — READ BEFORE ANY TOOL CALL

You are inside the `/last30days` SKILL. This is a specific research tool with a 1400+ line instruction contract (the rest of this file) that defines EXACTLY how to produce the research output. It is not a generic "last 30 days of X" research prompt. Do NOT treat `/last30days` as a search keyword you can improvise against.

**Named failure mode (2026-04-18 public v3.0.6 0/8 regression):** on 8 consecutive public invocations, Opus 4.7 treated `/last30days` as a generic research keyword and improvised. Every single run violated LAW 2 (invented titles like "The headline", "Kanye West: the last 30 days"), LAW 4 (section headers like "Why he is everywhere this month", "1. gstack dominates", "The 'Homecoming' peak"), or both. One run (Matt Van Horn) skipped Step 0.5 / Step 0.55 entirely and ran the engine bare with zero resolution flags. Another (Garry Tan) leaked a trailing `Sources:` block despite LAW 1 reinforcement at four tiers. Two runs (Peter Steinberger, Kanye vs Kim) landed on a stale `~/.openclaw/skills/last30days/` engine copy via a self-written path-discovery loop.

**How v3.0.7 fixes it:** three structural anchors.
1. **The MANDATORY first-line badge** (`🌐 last30days v{VERSION} · synced {YYYY-MM-DD}`) at the top of every response is the LAW 2 / LAW 4 enforcement anchor. See "BADGE (MANDATORY, FIRST LINE OF OUTPUT)" in the synthesis section.
2. **The SKILL_DIR substitution** in the engine Bash calls uses the directory of the SKILL.md the model just Read — no resolver list, no precedence walk. Whichever install the harness loaded SKILL.md from is the install whose engine runs. Aligns spec-with-code and works for any harness without enumerating its install path.
3. **This preface** tells you plainly: do NOT improvise. Follow SKILL.md top to bottom.

If you catch yourself about to write a `##` section header in a GENERAL-query body, a custom title line, a `Sources:` bullet list, a `for dir in ...` path-discovery loop, or a bare `python3 scripts/last30days.py "{TOPIC}"` engine call with no pre-flight flags — stop. Those are the exact failure modes the LAWs and this contract exist to prevent. The 10/10 beta validation from 2026-04-18 and the 0/8 public v3.0.6 regression from the same day had THE SAME MODEL and SIMILAR SKILL.md CONTENT; the delta is the three anchors this release restores. Read SKILL.md top to bottom before emitting your first response.

# OUTPUT CONTRACT (BADGE + LAWS — READ BEFORE EMITTING YOUR RESPONSE)

These anchors used to live at line 1094 of this file. Three independent Opus 4.7 self-debugs on 2026-04-18 confirmed the file was too long to reach them before synthesis. Moved here in v3.0.8. Do not synthesize without reading this section.

**BADGE (MANDATORY, FIRST LINE OF OUTPUT):** The Python engine now emits the badge as the first line of its `--emit=compact` stdout. Your correct behavior is to PASS THROUGH the script's output verbatim. If you are writing your own synthesis from scratch and need to emit the badge yourself, use:

```
🌐 last30days v{VERSION} · synced {YYYY-MM-DD}
```

Replace `{VERSION}` with the installed plugin version (`jq -r '.version' "$SKILL_DIR/../../.claude-plugin/plugin.json" 2>/dev/null || awk '/^version:/{gsub(/"/,"",$2); print $2; exit}' "$SKILL_DIR/SKILL.md"`) and `{YYYY-MM-DD}` with today's date. No other text on this line. One blank line after, then the synthesis begins.

**Why the badge is MANDATORY:** it is the structural anchor for the canonical output shape. Without it the model drifts into blog-post narrative format with `##` section headers and invented titles, violating LAW 2 and LAW 4. The 2026-04-18 public v3.0.6 0/8 regression produced outputs with section headers like "The headline", "Why he is everywhere", "1. gstack dominates", "The 'Homecoming' peak". Direct cause: this anchor was absent. Do NOT skip the badge. Do NOT describe it. Do NOT paraphrase it. Emit it verbatim as line 1.

**Placement by query type:**
- GENERAL /
