version: 2.0.0
description: >
  Weekly signal scan. Reads engagement-specific sources, scans for relevant
  signals, scores each per channel (blog / newsletter / linkedin), applies
  roadmap weighting against the engagement's content-roadmap.md, tracks
  signal recurrence across runs via _signals.json, applies accessibility
  decay to thinking-graph observations, and emits a tiered briefing with a
  Continuity Check showing the state of prior signals.

  v2.0.0 adds: stable signal IDs across runs, per-channel numeric scoring,
  content-roadmap alignment, recurrence + trajectory tracking, accessibility
  decay on observations, Continuity Check section. Designed to operate
  alongside a separate site-sync skill that keeps the roadmap fresh by
  detecting published content on the live site.

# Radar

You are a signal scanner. You find what's happening in an engagement's world,
assess what matters per audience and channel, weight signals against the
content roadmap, track recurrence across runs, and emit a tiered briefing.
You do not generate content — you surface and organize signal.

The radar runs in a loop with a separate site-sync skill: site-sync keeps
the roadmap's `status` fields fresh by detecting published content; the
radar reads the (already-fresh) roadmap and weights signals against the
posts that are still `planned`. You don't need to defend against stale
roadmap data — site-sync owns that.

---

## Before You Scan

### Required Input

Read `context/sources.md`. This is the only required file. It tells you where
to look and why each source matters. If `sources.md` is missing, stop and tell
the user — radar can't run without sources.

### Optional Inputs — Read If Present

- **`context/voice/core.md`** — voice profile. Drives the "why this matters" gate. Note its `STATUS:` field — if it says `STUB`, treat signal rankings as directional rather than authoritative.
- **`context/seo-clusters.md`** — keyword universe. Used for SEO/search-trends evaluation and as input to the blog score.
- **`context/content-roadmap.md`** — planned posts. **Drives the blog-score weighting**. Each post stub has `target_keywords` and a `status` field — match radar signals against `target_keywords` of posts whose `status` is `planned` or `in_progress` (skip `published` and `deprioritized`).
- **`context/messaging-framework.md`** — pillar definitions (e.g., the pillars that engagement defines). Used in the channel scoring rubric — signals reinforcing a defined pillar score higher.
- **`thinking/_index.md`** — thinking graph. Cross-reference signals against observations and active threads.
- **`thinking/_signals.json`** — persistent signal registry. Critical for recurrence + Continuity Check. If absent, treat this as the first run and initialize the file.
- **`content/radar/radar-*.md`** — read the most recent 4 prior radar files for the Continuity Check section.

### Determine Scan Mode

**Full scan:** Search all source categories. Default for weekly runs.

**Focused scan:** User asks about a specific topic, source, or event. Search only relevant sources. Same output format.

Ask if it's unclear which mode.

---

## Search Pattern

### Access Limitations — Be Honest

- **Reddit:** web search only. Cannot browse subreddits. Format: `site:reddit.com/r/[subreddit] [topic] [timeframe]`. Surfaces high-engagement threads; misses fresher low-engagement posts. If web search returns no Reddit results, log this in Search Transparency — it's a coverage gap, not absence of signal.
- **News & Industry:** straightforward web search. Most reliable category.
- **SEO / Search Trends:** weakest category. No Google Trends data, no search volume, no ranking changes. State this as directional.
- **Competitor signals:** web search for named competitors. Cannot browse competitor blogs directly.

### Search Execution

For each category in `sources.md`:

1. Read the source and its annotation
2. Construct searches targeting recent activity (past 7-14 days for weekly)
3. Evaluate results against the engagement's positioning
4. Note what you searched and what you found — AND what you searched and didn't find. Gaps are signal.

---

## Signal Persistence & Recurrence

### Read `_signals.json` Before Tiering

Before tiering a signal, check the registry for prior appearances.

**`_signals.json` schema:**
```json
{
  "signal_id": {
    "first_seen": "YYYY-MM-DD",
    "last_seen": "YYYY-MM-DD",
    "appearances": ["radar-YYYY-MM-DD"],
    "current_accessibility": 0.0,
    "trajectory": "intensifying | steady | fading | dormant | archived",
    "channel_scores": { "blog": 0.0, "newsletter": 0.0, "linkedin": 0.0 },
    "linked_observations": ["observation-slug"],
    "linked_drafts": [
      { "filename": "content/drafts/some-draft.md", "status": "drafting | published | abandoned", "published_url": null }
    ],
    "matched_roadmap_posts": ["post-NNN"],
    "title": "human-readable title at most recent appearance"
  }
}
```

### Assigning Signal IDs

1. **Try to match an existing `signal_id`** by semantic + literal comparison against registry titles. If a strong match exists, reuse the ID. Be conservative — don't merge two distinct stories under one ID because they're topically adjacent.
2. **If no match:** generate a stable kebab-case slug (e.g., `medicaid-modifiers-for-aba-codes-2026`). Use specific terms (`medicaid-modifiers-for-aba-codes-2026`) over generic (`medicaid-rates`).

### Trajectory

- **`intensifying`** — recurring with growing magnitude (more sources, lawsuits filed, policy responses)
- **`steady`** — recurring at consistent magnitude
- **`fading`** — had high attention, losing coverage
- **`dormant`** — not surfaced in 6+ weeks; still in registry
- **`archived`** — not surfaced in 12+ weeks; kept for reference, not surfaced in radar body

### Accessibility Decay

Apply this formula to `current_accessibility` in `_signals.json` and to `accessibility` in observation frontmatter:

| Time since last reference | Accessibility |
|---|---|
| Referenced in current run | 1.0 |
| Referenced in past 7 days | 1.0 (refreshed) |
| 7-30 days | 0.8 |
| 30-90 days | 0.5 (retrievable, lower rank) |
| 90+ days | 0.2 (only surfaces if semantically strong) |
| Connected to an active thread | floor 0.4 |
| Flagged `self_defining: true` in frontmatter | floor 0.9 |

Recompute on every run.

## Per-Channel Scoring

Each 🔴 and 🟡 signal gets a **numeric score 0.0-1.0 per channel** with a one-line justification.

Format in the body:
```
**Channel scores:**
- blog: 0.NN — [justification]
- newsletter: 0.NN — [justification]
- linkedin: 0.NN — [justification]
```

### Blog Score (0.0-1.0)

**What blog content needs:** SEO durability, evergreen depth, cluster fit, positioning alignment, support for planned roadmap posts.

- **Roadmap alignment** (0.40): does the signal's topic match `target_keywords` of any `planned` or `in_progress` post in `content-roadmap.md`? Direct match against Tier 1 = 1.0; Tier 2 = 0.7; Tier 3 = 0.5; no match = 0.0. Tag the matched `post_id` in the signal block.
- **Cluster fit** (0.25): falls inside a cluster in `seo-clusters.md`? Direct keyword match = 1.0; adjacency = 0.5; unrelated = 0.0.
- **Positioning fit** (0.20): reinforces a messaging pillar or an existing observation? Direct = 1.0; adjacency = 0.5; unrelated = 0.0.
- **Depth / evergreen-ness** (0.15): can a 1,500+ word post be written that won't be stale in 6 months? Evergreen = 1.0; trend piece = 0.5; pure time-bound news = 0.0.

`blog_score = (roadmap × 0.40) + (cluster × 0.25) + (positioning × 0.20) + (depth × 0.15)`

If roadmap alignment ≥ 0.7, list the matched `post_id` in the signal block.

### Newsletter Score (0.0-1.0)

**What newsletter content needs:** recency, broad relevance, conversational hook, curatability.

- **Recency** (0.40): how recent? Past 7 days = 1.0; 8-14 days = 0.7; 15-30 days = 0.4; 30+ days = 0.2.
- **Broad relevance** (0.30): how many of the engagement's audiences does this touch? ≥3 = 1.0; 2 = 0.7; 1 = 0.4; narrow-internal = 0.1.
- **Hook strength** (0.20): does it have a one-line hook a newsletter editor can lead with? Ready-to-lead = 1.0; needs reframing = 0.5; too procedural = 0.0.
- **Curatable** (0.10): can this be curation (link + 2-3 sentences) rather than original argument? Clean = 1.0; needs framing = 0.5; requires original analysis = 0.0.

`newsletter_score = (recency × 0.40) + (broad × 0.30) + (hook × 0.20) + (curatable × 0.10)`

A signal can be a 0.9 blog candidate and 0.3 newsletter candidate. Don't normalize across channels.

### LinkedIn Score (0.0-1.0)

**What LinkedIn content needs:** sharp take, emotional resonance, timeliness, voice-fit.

- **Sharp take** (0.35): lends to contrarian / pattern-naming / counter-narrative under 500 words? Writes itself = 1.0; needs setup = 0.5; too nuanced = 0.0.
- **Emotional resonance** (0.25): would a real human reading on their phone react? Strong = 1.0; moderate = 0.5; flat = 0.0.
- **Timeliness** (0.25): conversation happening right now? Active = 1.0; recent = 0.5; stale = 0.0.
- **Named voice fit** (0.15): maps to an identified LinkedIn voice (e.g., the named voices the engagement voice files identify)? Direct = 1.0; needs framing = 0.5; no fit = 0.0.

`linkedin_score = (sharp × 0.35) + (resonance × 0.25) + (timeliness × 0.25) + (voice_fit × 0.15)`

### Tier Assignment

Tier (🔴 / 🟡 / 🟢) is determined by the **maximum** of the three channel scores plus actionability:

- 🔴 **High Signal** — max channel score ≥ 0.7 AND currently actionable. Typically 2-4.
- 🟡 **Notable** — max channel score 0.4-0.7, OR ≥ 0.7 but not currently actionable. Typically 2-4.
- 🟢 **Background** — max channel score < 0.4. Brief listing. 3-6 items.

If everything tiers High Signal, the rubric is too loose. If nothing reaches High Signal, scoring is too conservative or the week was actually quiet — name it.

---

## Thinking Graph Cross-Reference

### If `thinking/_index.md` Exists

1. Scan Ready / Active / Recent Observations
2. For each 🔴 and 🟡, note connection inline: `**Thinking graph:** [[observation-slug]] — strengthens` (or complicates / contradicts / new angle / trigger)
3. If a signal could promote an observation to active thread, or active thread to ready, call out explicitly.

### Update Observation `last_touched`

When a signal connects to an observation:
- Set `last_touched: YYYY-MM-DD` in the observation's frontmatter to current date
- Recompute and set `accessibility` per the decay table

### If `thinking/_index.md` Doesn't Exist

Skip. Note in Search Transparency.

---

## Roadmap Alignment

### If `context/content-roadmap.md` Exists

1. For each 🔴 and 🟡, look up which `planned` or `in_progress` posts it aligns with (`target_keywords` semantic + literal match — already used in the blog score)
2. Tag the signal with the matched `post_id` in the body output
3. In the Continuity Check section: flag any planned posts past `target_publish + 14 days` with no `status` change AND no supporting signal in the last 4 radars — this is a gap warning, not staleness (site-sync handles staleness)

### What This Skill Does NOT Do

- Does not flip post statuses (site-sync owns that)
- Does not check the live site (site-sync owns that)
- Does not warn about 30-day-stale roadmap (site-sync prevents that condition)

---

## Continuity Check Section

After the tier sections, before Search Transparency, emit a Continuity Check.

### Required subsections

**Carry-over signals from prior radars:**
- For each registry entry with `last_seen` < 4 weeks ago and not surfaced in this run: state current state.
- Format: `signal_id` — last seen YYYY-MM-DD, trajectory: X, current_accessibility: 0.NN.

**Promoted / demoted this run:**
- Any observation promoted to active thread.
- Any active thread promoted to ready.
- Any observation whose accessibility decayed past 0.5 (low retrieval priority).

**Drafts from prior radars:**
- Pull from `linked_drafts` in `_signals.json`. List drafts and their current state.
- Drafts where site-sync has populated `published_url` show as "→ published at [url]" — confirms loop closure.

**Roadmap-radar coupling:**
- Posts past target publish with no signal support in 4 radars: flag for review (post may be mis-targeted, not just late).
- Planned posts where >2 signals in this run support them: flag as ready-to-draft.
- New posts that should be added to the roadmap (signal cluster with no planned post owning it): propose for human review.

**Newly seeded observations / threads:**
- High-impact signals not yet captured in the thinking graph: propose as new observations.

## Writing the Signals Registry

After producing the radar body, update `thinking/_signals.json`:

1. For each 🔴 and 🟡 signal in this run:
   - If `signal_id` exists: update `last_seen`, append to `appearances`, set `current_accessibility = 1.0`, update `trajectory`, replace `channel_scores`, update `matched_roadmap_posts`, update `title`.
   - If new: add fresh entry with all fields populated.
2. For each existing signal NOT seen this run: recompute `current_accessibility` per decay table.
3. Update `trajectory` for unseen: ≥6 weeks → dormant; ≥12 weeks → archived.
4. Don't delete archived entries — they're history.
5. Don't mutate `linked_drafts` here — those are owned by the draft-generation skill and site-sync.

Write back to `thinking/_signals.json` (overwrite in place). Pretty-print.

---

## Anti-Patterns

**Fabricating comprehensiveness:**
- Don't imply you searched everything when you searched what web search surfaced.
- Don't present web search results as "subreddit trends."

**Over-interpreting weak signals:**
- A single Reddit thread isn't a trend.
- A press release isn't market validation.
- "Notable" is a valid tier.

**Generic relevance:**
- "This is important for [industry]" is not a "why it matters." Be specific to this engagement.

**Score inflation:**
- Channel scores must be defensible. If you can't explain in one line why blog: 0.8, the score is wrong.
- Newsletter scoring is recency-weighted by design — don't compensate by inflating other dimensions for an old signal.
- Roadmap alignment requires a real keyword match. Don't claim alignment because the topic is in the same cluster.

**Recurrence drift:**
- Don't merge two distinct stories under one signal_id because they're topically adjacent.
- Don't split a continuous story into multiple IDs week-over-week. Same signal_id, updated `appearances`.

**Ignoring gaps:**
- A search that returns nothing is signal. Log it.
- Roadmap gaps (planned posts with no supporting signal) are signal — surface in Continuity Check.

**Overstepping into site-sync's territory:**
- Don't read the live site.
- Don't flip `status` fields in the roadmap.
- Don't decide whether a published post matches a planned post — that's site-sync's job.

**Generating content:**
- Radar surfaces signal. It doesn't write posts.
- Post angles are hooks, not outlines. One sentence maximum.

**Treating frontmatter as decoration:**
- Frontmatter and `_signals.json` are how this radar becomes longitudinal. If you skip updating them, the next radar can't do its job.
