Lythoskill Project Scribe Weekly

Project Scribe — Weekly

Distill, don't replay. The core thread matters; the 17 commits that touched it don't.

Value Boundary

Weekly is a memory offloading mechanism, not a menu listing.

If the next agent can find it via ls daily/, git log, or cortex index — don't replicate it. Link to it.

Why this matters: A future agent reading a weekly cold (no daily access) should get the compressed representation of the week's cognitive work — the pattern, not the commits. Without this, every agent must reconstruct the narrative from 6 daily files + 29 commits + 10 ADRs. Weekly offloads that reconstruction cost once, permanently.

Weekly Prep (like cortex probe — gather before you write)

Do NOT start writing from memory. Run prep first. This is the write-side counterpart to onboarding's read-side: just as onboarding reads daily → verifies git → presents summary, weekly prep gathers all sources → surfaces anomalies → ranks importance.

Step 1: Gather (deterministic)

# ISO week alignment check — confirm what week we're in and what span to cover
python3 -c "import datetime; d = datetime.date.today(); iso = d.isocalendar(); \
  mon = d - datetime.timedelta(days=d.weekday()); \
  sun = mon + datetime.timedelta(days=6); \
  print(f'Today: {d} ({d.strftime(\"%A\")}) — ISO W{iso.week}'); \
  print(f'Standard span: {mon}_to_{sun}')"

# Daily surface — which days had activity?
ls daily/*.md | sort | tail -7

# Git surface — what actually landed?
git log --since="7 days ago" --oneline

# Cortex surface — what state changed?
bunx @lythos/project-cortex@0.19.1 probe
bunx @lythos/project-cortex@0.19.1 stats

# ADR surface — what decisions were accepted this period?
ls -lt cortex/adr/02-accepted/ | head -15

# Delta from last weekly — what's new since the last snapshot?
ls weekly/ | sort | tail -1

Step 2: Surface Anomalies

Scan the gathered data for:

• Superseded decisions: later ADR that contradicts an earlier one (e.g., combo redefinition May 6 superseded May 1 section semantics)
• Renamed/removed commands: CLI surface changed (e.g., agent-run → single, deck sync → deck to-symlink)
• Reversed priorities: a task/epic that was priority_at_start last week but never appeared in this week's dailies
• Silent gaps: days with no daily file but git shows commits (someone committed outside agent session)
• Missing ADRs: significant code/architecture change in git log with no corresponding ADR accepted in the same window. A rename with 30+ commits and no ADR is a red flag.

Step 3: Importance Ranking (simulated annealing)

1. High temperature: dump every event you can recall. Don't filter. Include everything.
2. Cool: group related events into clusters (e.g., "path convention fixes" = 5 commits, 2 ADRs, 1 ZK sweep)
3. Rank clusters by downstream confusion cost: "if a future agent missed this cluster, how wrong would their decisions be?"
4. Freeze: top 1-2 clusters → core_thread. Clusters that involve superseded docs → docs_now_stale.

Test: can you identify the single most important decision of the week? If the combo redefinition (May 6) would be invisible in your weekly, you didn't rank correctly.

Step 4: Prep Report (show to user before writing)

Present a 5-line summary:

📊 Weekly Prep — 2026-W22
📄 Dailies: 2026-05-21, 2026-05-28 (gap May 22-27)
🔀 ADRs: 3 proposed, 0 accepted this period
⚠️  Anomalies: combo redefinition (May 6) not captured in any weekly
💡 Top cluster: site documentation debt cleanup (P0 → done)
📋 docs_now_stale candidates: ADR-20260501160000000, external-skill-governance-bridge.md

User confirms → proceed to write. User flags missing items → add to cluster list.

When to Run

• User explicitly asks for weekly synthesis
• End of week (typically Sunday) for retrospective
• Friday afternoon: if the week has already produced substantial work and user wants to capture it before weekend
• Sunday night: if weekend work continued the week's thread — append to existing weekly, don't create new
• Monday: if weekend was quiet and weekly wasn't written yet
• Before epic planning to understand what unlocked/paused
• Do NOT auto-schedule — the player decides timing

Sunday Check (agent-initiated suggestion)

If today is Sunday and you observe any of these signals during session close:

• Epic/task cleanup feeling ("this phase feels done")
• Goal reached at a natural milestone (milestone completed, tests pass, push to remote)
• User says "LGTM", "就这样" ("that's it"), "先到这里" ("let's stop here") on a Sunday

Suggest to the user, in their own language: this week's work seems to have reached a natural close — do they want to consolidate a weekly and record the week's pattern?

User says yes → run weekly prep. User says no or ignores → write daily scribe as usual, don't push.

Weekly Writing Modes

Daily scribe continues regardless. Weekly does not replace daily; they are different abstraction layers.

Inputs (collect before writing)

# 1. Daily files from the past 7 days
ls daily/*.md | sort | tail -7

# 2. Git activity (for reference, not replay)
git log --since="7 days ago" --oneline

# 3. Current cortex state
bunx @lythos/project-cortex@0.19.1 index
bunx @lythos/project-cortex@0.19.1 stats

# Cortex uses timestamp IDs (ADR-yyyyMMddHHmmssSSS, TASK-...,
# EPIC-...). This lets you grep by date range:
#   ls cortex/adr/02-accepted/ | grep '^ADR-2026051'
# Use this when reconstructing a missing weekly from ground truth.

# 4. Session recall — ask yourself:
#    - What was the priority at week start?
#    - What actually got done vs paused?
#    - What emerged mid-week that wasn't planned?
#    - What pattern repeated across multiple days?

Output: weekly/YYYY-Wxx.md

Body (~200-300 words, NOT a replay)

1. TL;DR (1 paragraph): core thread + the one decision that mattered most.
2. 4-Quadrant Retro (table): planned vs emergent × done vs paused.
3. Quest DAG: ASCII or Mermaid diagram of epic/task flow.
4. Project Lesson Candidates: bullets for patterns worth crystallizing.
5. Reference Pointers: links to daily files and indexes. Don't replicate.

The 4-Quadrant Retrospective

Compare intended priorities against actual execution:

Rule of thumb: One concise line per cell explaining what happened and why. Not a task list.

Salience Filter

"太细节的小事不会在 weekly 里。特别强烈的印象会在。" ("Tiny details don't go in the weekly. What goes in is what left a strong impression.")

Test: If a future agent reading this weekly cold (no daily access) would mistake a detail for a non-event, it doesn't belong.

Verify Companion

Before relying on a weekly for planning, spot-check its claims against ground truth:

# Does the recorded epic/task status match reality?
bunx @lythos/project-cortex@0.19.1 probe

# Does the git activity match the claimed period?
git log --since="2026-05-01" --until="2026-05-07" --oneline

# Do the referenced daily files exist?
ls daily/2026-05-*.md

Wrong facts in weekly = disaster for next agent. The agent owns this verification — there is no validate-weekly CLI; weekly is a pure skill that produces a doc, the agent uses cortex probe + git log + daily ls to reality-check what it just wrote.

Decision Hygiene (agent behavior)

Do not present fake options. When asking user for next step, every option must be a real choice with different consequences. Do not include:

• Options that transfer cost to future sessions (e.g., "end session and let next agent handle it")
• Options that are obviously inferior (e.g., "do nothing" when action is clearly needed)
• Options that defer without reason (e.g., "wait" without explaining what we're waiting for)

Why: Fake options waste user attention. They feel like marketing tricks — psychological anchors designed to make one option look good by contrast. Respect user time by offering genuine trade-offs or making the recommendation directly.

Pattern: If you know what should happen, say so. If you need user input, offer 2-3 real alternatives with consequence briefs. If there's no real choice, don't ask.

Examples:

• ❌ "Should I A) verify now B) end session C) do nothing" — C is fake
• ✅ "I recommend verifying now — cost is 1 minute, benefit is catching skill drift before next session. Confirm?"
• ✅ "Two paths: A) quick scan (5 min, surface only) B) deep audit (30 min, full checklist). Which fits your time?"

Scenarios & Packages (v0.1 — explore with user)

Weekly writing is not a rigid procedure. It's a scenario-driven, package-based exploration between agent and user. Like an ADV game: there are branches, but each branch has a default skeleton.

Scene A: Weekly Writing

Trigger: User says "写 weekly" ("write the weekly") / "这周总结一下" ("summarize this week") / end-of-week feeling

Agent choice: Run ls weekly/*.md | sort | tail -3 to detect mode. Recommend package to user. User confirms or overrides.

Scene B: User Says "消债" / "扫一下" / "还债" ("pay down debt" / "sweep" / "clear debt" — user wants a cleanup audit of accumulated documentation/governance debt)

Trigger: User explicitly asks for cleanup / audit / sweep

Agent choice: Ask user "quick scan or deep?" Default to B1 if user just says "消债" ("pay down debt") without qualifier.

Scene C: Session Close (Scribe)

Trigger: User says "LGTM" / "先到这里" ("let's stop here") / session ending

Agent choice: Default C1. Switch to C2 only if session content clearly spans weeks or user explicitly mentions weekly.

Scene D: Release Prep

Trigger: User says "release" / "ship it" / version bump

Agent choice: User names release scope → select package. Default D1 for patch, D2 for minor, D3 for major.

Scene E: Quarterly Dreaming

Trigger: User says "做梦" ("dreaming" — user asks for memory consolidation) / "consolidate" / "memory cleanup"

Agent choice: Dreaming skill owns this. Weekly skill provides weekly chain as input.

Long-Range Consistency Principle

Weekly is the anchor for long-range consistency. Not because it's the most frequent, but because it's the right frequency:

• daily: too frequent, compaction makes it unreliable for drift detection
• weekly: just right — regular enough to catch drift, sparse enough to survive compaction
• quarterly: too sparse, drift accumulates beyond easy repair

The weekly chain (weekly/2026-W17.md, 2026-W18.md, ...) is a temporal index. Future agents reading cold can:

1. Find the latest weekly → know current ISO week
2. Follow chain backward → reconstruct narrative
3. Detect gaps → know where drift occurred

This is the project's memory infrastructure in practice.
