Related skills: Called at publish time after Distribution Translator runs (or on manual trigger). Reads the published post to extract used analogies; writes to shared-context/analogy-catalog.md. Does NOT fire on seed or draft creation.

When this fires

• User publishes a post (moves draft to corpus/published/{section}/).
• User runs update-analogy-catalog explicitly on a published post.
• Never on seed or draft.

Workflow

For a newly published post:
- [ ] Step 1: Read the published post file
- [ ] Step 2: Extract non-trivial analogies (present a source-target mapping with mechanical weight)
- [ ] Step 3: For each, determine freshness (new / reused / borrowed)
- [ ] Step 4: For each, extract where-it-breaks if named
- [ ] Step 5: Write one entry per analogy to analogy-catalog.md
- [ ] Step 6: Commit ledger-style entry with date + post reference

Step 2: Non-trivial extraction

Trivial similes don't count ("fast as lightning"). An analogy is non-trivial if:

• It has a named source domain (bucket brigade, immune system, courtroom)
• It maps to a specific technical target
• The mapping does work in the post (remove it and the explanation suffers)

The writer can manually annotate analogy: true in a post's frontmatter to force inclusion, or analogy: skip to exclude.

Step 3: Freshness

• fresh: the writer's own analogy, first use. Default.
• reused: the writer used this analogy in a prior published post. Auto-detected by cross-checking the catalog.
• borrowed: the analogy came from a named source (Hofstadter, a cited paper). Writer annotates.

Entry schema

Append to analogy-catalog.md under the table:

| {source} | {target} | {post-title} | {fresh|reused|borrowed} | {note} |

Also in the "notes" section at the bottom:

## {post-slug} — YYYY-MM-DD
- analogy: {source} → {target}
- freshness: fresh|reused|borrowed
- why it worked: {one-sentence note from the writer or inferred from post context}
- breaks at: {the boundary the writer named in the post, if any}

Worked example

Event: Writer publishes "Why your embedding search melted at 10pm" on 2026-05-20. The post uses two analogies:

1. "The retrieval layer is the thermometer" — monitoring-as-sensing; maps concept "retrieval quality metric" to "thermostat reading."
2. "RAG is prosthetic memory" — borrowed from 2026-03-03-rag-as-prosthetic-memory (already in corpus/seeds/ earlier).

Detection:

• Analogy 1: source thermometer, target retrieval quality metric. Not in catalog. Freshness: fresh.
• Analogy 2: source prosthetic memory, target RAG. Already in catalog from a prior post. Freshness: reused. Cross-reference to the prior entry.

Catalog update:

source	target	post	freshness	note
thermometer	retrieval quality metric	Why your embedding search melted at 10pm	fresh	"you need to sense before you can steer" — operational framing
prosthetic memory (reused)	RAG	Why your embedding search melted at 10pm	reused	sibling to 2026-03-03 post; same frame, new context

Guardrails

1. Only fires on publish. Never on seed or draft.
2. Reused analogies are a feature, not an error. Log them as reused; let the writer decide if a future post should freshen up.
3. Trivial similes are excluded. A rule of thumb: if removing the simile changes nothing about the explanation, skip it.
4. Borrowed analogies require attribution. If the writer doesn't name the source (Hofstadter, Feynman, a paper), mark freshness: fresh but flag for writer review.
5. Never edit existing catalog entries. Append-only.
6. If the writer explicitly marks analogy: skip in post frontmatter, respect it.

Quick reference

• Fires on publish only.
• Appends rows to the analogy-catalog table + detailed notes section.
• Reuses are flagged, not errors.
