description	Generates an experiment-overview snapshot of all research questions under research/_archive/. Invoke when a new point-in-time report across all RQs should be produced.

/build-overview — produce an experiment-overview snapshot

You produce a frozen, publishable research report from the current state of every findings.md under research/questions-claude/, research/questions-opencode/, research/questions-cross/, and research/workflow-dev/. The snapshot lands as a new file under research/_archive/experiment-overview-YYYY-MM-DD.md.

Core principle

findings.md = living document, growing list of status-tagged findings. Snapshot = frozen, table-heavy report at a point in time.

Both exist in parallel. The snapshot is not written from memory — it is filled in from an auto-generated skeleton.

Prerequisites

System tools required (all on $PATH):

• python3 — runs experiments/generate-snapshot-skeleton.py
• pandoc — Markdown → HTML for the PDF step (any version ≥ 2.9 works)
• google-chrome (or chromium — adjust the binary name in step 6) — headless --print-to-pdf
• pdfinfo (Poppler utils) — optional, used for the PDF verification check in step 6

If any of these are missing, stop at step 6 and report which tool is unavailable so the user can install it.

Lifecycle (6 steps)

Step 1 — generate the skeleton

Bash:

./experiments/generate-snapshot-skeleton.py

The script writes to /tmp/snapshot-skeleton-YYYY-MM-DD.md. It auto-fills:

• Data-base count (from experiments/runs/)
• Author line (Marco Emrich, with EXACT-Coding co-credit "gemeinsam mit Ferdinand Ade")
• Repository link (github.com/marcoemrich/agentic_coding_lab)
• ## Über die Studie H2 — only the heading; the two flowing paragraphs underneath are TODO-markers (filled in step 3)
• ### Scope H3 sub-heading — TODO-marker (filled in step 3)
• ### AI-Hinweis H3 sub-heading — full text is static
• ## Hauptbefunde H2 — TODO-marker (filled interactively in step 4)
• §1 Research-question overview table with per-RQ coverage (data-driven, regenerated from frontmatter)
• §2.1 Experiment-design tables: Workflow, Modell × Thinking, Kata × Prompt-Stil — all static
• §2.1 Workflow-Mechanik im Detail block — static, one bullet per workflow generation
• §2.2 Workflow → Prompt-Mapping table — static
• §3 Methodology block — static, with a freshness-check TODO marker
• §3.2 Metrik-Tabellen (six grouped tables: Korrektheit, Effizienz, Code-Mass & Umfang, Code-Qualität, Test-Stärke, TDD-Disziplin) — all static
• §3.3 Bewertungsgrundsätze — static
• §4 Per RQ: heading + Datenbasis line + raw finding list + per-RQ synthesis TODO (current state, no status tags)
• §7 Reproducibility block — static
• §8 Files table — data-driven

Wherever you must fill in content, a <!-- TODO Claude: ... --> marker is left in place. Everything else is static skeleton content — do not edit it during synthesis. Concretely: Author / Repository / AI-Hinweis blocks, all §1 / §2 / §3 / §7 / §8 tables and prose, and the Workflow-Mechanik block must stay byte-identical to what the skeleton produced.

Step 2 — read the skeleton + every findings.md

Read the skeleton (/tmp/snapshot-skeleton-YYYY-MM-DD.md) and every findings.md under research/questions-claude/*/, research/questions-opencode/*/, research/questions-cross/*/, and research/workflow-dev/*/ (skip dirs starting with _). Note for each RQ the current findings with their statement and data values.

open-questions.md (when present) does not go into the snapshot — those are internal backlog items for future batches, not publishable state.

Step 3 — fill in the synthesis sections (except Hauptbefunde)

Replace every <!-- TODO Claude: ... --> marker with real content — except the ## Hauptbefunde TODO, which is handled interactively in step 4. Never leave any other TODO marker in place.

Style requirements:

• Glossary discipline: Before step 3, read the glossary in the top-level README.md. Use terms like code_mass, cc_loc, cc_longest_function, smell_total, verification_pct only in the binding form defined there ("Code-Mass (APP)", "Produktiv-LoC", "Spitzen-Komplexität", "Smell-Summe", "Korrektheit (außen)") or directly via the metric ID in backticks. Synonyms like "Code-Volumen", "Code-Gesamtvolumen", "LoC-Größe" are forbidden — they are ambiguous or collide with established definitions (APP).
• ## Über die Studie (H2): Two flowing paragraphs (no sub-headings between them):
  • Paragraph 1 — EXACT Coding anchor. Lab as the empirical validation platform for EXACT Coding (EXample-guided AI-Collaborative Test-driven Coding) — reference the manuscript at ../../../exact-coding-book/manuscript/exact-coding.md (path relative to the repo root). Position the workflow variants as a spectrum from Vibe-Coding baselines (v1/v2) over EXACT-conformant setups (v4/v6) to the Delayed-Refactor control (v8).
  • Paragraph 2 — Snapshot status. Date, run count, RQ count, current research front. Never use workflow version names (v6.1-hybrid etc.) here — workflows are not yet introduced in §2.1; describe by mechanism instead (e.g. "Hybrid-Workflow mit Skill-basiertem Red/Green im geteilten Kontext + isoliertem Refactor-Subagent"). Mention any excluded workflow-dev RQs if their data collection is still ongoing.
• ### Scope (H3 sub-heading inside Über die Studie): One paragraph with the three-axis scope named explicitly: (1) Harness — Claude Code CLI (pin the version from experiments/docker/Dockerfile), headless without HITL; (2) Models — only Anthropic models (Opus, Sonnet, Haiku — with/without thinking, Direct-API and Portkey); (3) Target language — only TypeScript with the fixed pnpm/tsx/Vitest/ESLint+SonarJS stack per run. State explicitly that findings hold for this stack; transfer to other agentic tools (Cursor, Aider, Cline, Windsurf), other model providers (OpenAI, Google, local models), other target languages (Python, Go, Java), or interactive HITL setups is open.
• Methodology (section 3): Skeleton content is static. Verify against experiments/docker/Dockerfile, experiments/analyze-run.sh, experiments/aggregate-by-query.py whether the pipeline description is still accurate. On drift, correct in the snapshot. Replace the <!-- TODO Claude: check whether still current ... --> marker with either a brief confirmation ("pipeline unchanged since ...") or the corrected steps.
• RQ sections (4.X): Two artefacts per RQ, in this order:
  • Übersichts-Tabelle from findings.md copied verbatim into the snapshot, placed directly after the _Datenbasis: …_ line and before the **Befunde**: list. Each findings.md carries an "Übersicht" or headline table near the top; copy it (with its caption + 🏆 markers) so readers see the numbers without leaving the snapshot. If a findings.md exposes two parallel overview tables (e.g. one per kata, as in RQ-tdd-quality), copy both.
  • Synthesis paragraph of 60–100 words after the **Befunde**: list. Top finding in detail + at most one caveat from the finding itself (e.g. narrow data base, only one kata) + an explicit [research/.../findings.md](relative/path) link. Where coverage < 100 %, name it in the synthesis ("with currently N runs in M of K cells ...").
• Findings convention: Snapshot shows only the current state. No status tags like ⚠️ bedingt / ✅ stabil, no comparisons with archive snapshots or older studies (e.g. the 235-run study). If findings.md still carries such status tags, drop them in the snapshot synthesis and only carry over the current statement. Reason: older runs had pipeline biases (see memory), comparisons are methodologically not robust.
• Trophy convention (🏆) in cross-RQ summary tables: If the snapshot includes pivot tables comparing workflows or models across outcomes, append 🏆 to the best value per row alongside the bold winner. Metric direction must be explicit (smell_total → "kleiner = besser", refactorings_applied → "höher = besser"). Award 🏆 only where the spread is meaningful — tied values get tied trophies, no winner gets fabricated from rounding noise. Same rule as in findings.md headline tables; see run-rq SKILL "Overview table" section for the full convention.
• Cross-RQ synthesis (5): 3–5 numbered points. Each point connects at least two RQs and would therefore not stand in any single findings.md.
• Limitations (7): 5–8 bullets. Mandatory: only Anthropic models, only synthetic katas, only TypeScript, headless without HITL, n ≤ 3 per cell. Optional: concrete coverage gaps from the per-RQ coverage values above (e.g. "RQ-model-quality only 1/5 cells fully populated").

Honesty rule: If an RQ has no robust findings in the current setup, do not invent something — say plainly "the current data base does not yield a robust finding" and use the synthesis to explain what is missing.

Step 4 — propose Hauptbefunde, let the human select

This is the only interactive step. Do not silently write the Hauptbefunde — propose candidates and let the user pick.

1. From everything you read in step 2, draft 5–7 candidate main findings that have the largest cross-RQ practical impact for a practitioner ("what should I take away?"). Each candidate carries: a bold-sentence title, 1–3 sentences with concrete numbers (verification_pct, cognitive_max, tokens), and a one-line practical consequence.
2. Present the candidates as a numbered list in chat, plus a short "why these and not others" line. Do not name workflow versions like v6.1-hybrid in the Hauptbefunde — workflows are not yet introduced at that early point in the document. Describe by mechanism instead ("Hybrid-Workflow mit Skill-basiertem Red/Green im geteilten Kontext + isoliertem Refactor-Subagent").
3. Use the question tool (multiSelect: true) to let the user pick 3–5 of the candidates. Accept "Other" answers as additions.
4. After the user has chosen, write the selected findings — verbatim with their bold titles and the practical-consequence line — into the ## Hauptbefunde block, replacing the TODO marker. Order the chosen findings by descending practical impact (most actionable first).

Step 5 — write the file

Take the date from the skeleton header (line 3: Stand: YYYY-MM-DD.) and write to:

research/_archive/experiment-overview-YYYY-MM-DD.md

Then verify with Glob or Read that:

1. The file exists
2. No <!-- TODO --> markers remain
3. All current findings from the findings.md files are referenced somewhere in the RQ sections (number + statement)
4. Each RQ section carries the Übersichts-Tabelle from its findings.md before the **Befunde**: list
5. No status tags (⚠️ bedingt, ✅ stabil) and no references to old studies / archive snapshots in the published snapshot

Step 6 — generate the PDF (mandatory)

The PDF is part of every snapshot — do not skip it, even if the user did not explicitly ask for one. Convert the Markdown snapshot to a PDF sibling via pandoc → Chromium headless:

SNAP=research/_archive/experiment-overview-YYYY-MM-DD
pandoc "$SNAP.md" -o "$SNAP.html" --standalone --self-contained \
  --metadata title="Experiment-Overview YYYY-MM-DD" \
  --css=experiments/snapshot-style.css
google-chrome --headless --no-sandbox --disable-gpu --no-pdf-header-footer \
  --print-to-pdf="$SNAP.pdf" "file://$(pwd)/$SNAP.html" 2>/dev/null
rm "$SNAP.html"

The stylesheet (experiments/snapshot-style.css) is checked in so every regeneration uses the same A4 layout, page-break rules (tables may span pages, individual rows stay intact, header repeats), and typography. The intermediate HTML is throwaway.

A harmless Failed to load module: …libgiolibproxy.so or VAAPI version is too old warning from Chromium can be ignored — they don't affect PDF output.

PDF verification. After generation, sanity-check the output:

pdfinfo "$SNAP.pdf" | grep -E "Pages|Page size|Page rot"

Expected: Pages ≥ 5, Page size ≈ 595 x 842 pts (A4), Page rot = 0. If any of these are off (e.g. zero pages, landscape page size, non-zero rotation), the PDF is broken — report it instead of pretending it worked.

Report at the end in 1–2 sentences the output paths (.md + .pdf), the page count, and any notable coverage gaps ("RQ-X is currently below min_replicates").

Style template

research/_archive/findings-validation-2026-05-04/experiment-overview-v2.md shows the target table density and section ordering. Read it for orientation before starting step 3. Adopt the table style and tone — not the specific numbers (those come from the current findings.md).

What is deliberately NOT part of your output

• Do not recompute or fabricate numbers — copy them verbatim from findings.md (Übersichts-Tabellen and finding-internal values). Numbers in tables come from findings.md, never from re-running aggregation or estimating.
• No auto-commit. The snapshot is reviewed by the user before it goes into the repo.
• No diff against the previous snapshot — that would be a separate skill.
• No subagent delegation; everything in the main context.
• Do not silently choose the Hauptbefunde for the user — step 4 is interactive by design.
