182 sessions across 5 project trees | 2026-03-14 to 2026-04-13 (30 days)
bot-dev agent (6) now do the heavy lifting on research, design, and Telegram-bot edits while you steer at a higher altitude. Today you closed the window with a Gmail-to-vault email pipeline built end-to-end via two bot-dev sub-agent dispatches. Impressive Things You Did →~/.claude/projects/-root/memory/ holds MEMORY.md plus 20+ project_*.md / feedback_*.md / tool_*.md notes that survive across sessions. You've codified six recurring corrections as feedback_*.md files (test persistence, duplication debt, adaptive-thinking config, Gemini model policy, API-vs-Max billing, Claude Code model policy) so each lesson is captured exactly once. New Usage Patterns →website, yaskawa, cloos-bot, qc-bot) but a new flavor has emerged: duplicated code drifting in parallel across multiple bot codebases (vault_index_file in 4 places). Where Things Go Wrong →vault_indexing.py extraction. Features to Try →The project mix is more concentrated than the prior window. Telegram bot work dominates, with the email-ingest build (today) and the Cloos/Teqram bot WhatsApp pipelines being the heaviest single threads. The Yaskawa cobot has moved from setup to active monitoring. New: weld_viz 3D simulator iterations show up as a recurring side-quest.
/root/develop/telegram_connection. Highlights: BGE-M3 embedding migration (384→1024-dim), worklog-aware vault chunking, hybrid memory search with company-name keyword boost, Media Pipeline v2 (Gemini 3 Flash photo/video/audio/PDF), self-heal v2, adaptive-thinking config fix. Today's session built the new email_ingest.py Gmail-to-vault pipeline as a self-contained module.tasks.arnereabel.com/floorplan/ behind nginx + Cloudflare tunnel. Weld Viz 3D welding physics simulator iterated from v2 to v18 (THREE.js + bloom + GLSL shaders) — 18 saved checkpoints on disk. Cloos Maintenance App debugged via the debugger subagent./root/health-check.sh runs every 5 min; daily /root/security-summary.sh at 08:00 UTC; on-demand /status command in the Telegram bot. UFW + fail2ban active. Hermes Gateway formally retired (disabled 2026-04-03 on QC, 2026-04-05 on main).Compared to three weeks ago, your operating mode has shifted up a level of abstraction. The previous report described you as a hands-on builder who threw Claude into the deep end with ambitious multi-step goals and supervised closely. That's still true at the top — but underneath, you now delegate to subagents. 85 invocations in 30 days, with Explore (48) replacing the manual "Claude, find X across the filesystem" prompts you used to write yourself, and Plan (21) catching design mistakes before code gets written. The project-specific bot-dev subagent took two of today's three biggest sub-tasks: building the email pipeline scaffolding, then adding the image gate + live test once you'd approved the design.
The other big shift: memory is now infrastructure, not an experiment. ~/.claude/projects/-root/memory/ holds 20+ files indexed from MEMORY.md. Six of them are explicit feedback_*.md notes — corrections you made to Claude's behavior, written down so you don't have to make them again. feedback_persist_tests.md exists because three test suites were deleted "after they passed"; that lesson now lives in your soul. feedback_duplication_debt.md exists because vault_index_file drifted across four files and someone (you) noticed. The bot also writes back to memory autonomously via the SessionStop hook.
Mechanically: 1,886 Bash invocations still dominate, but the Bash:Edit ratio (3.6:1) is much higher than the prior window's 4.8:1 — meaning when you do edit, you edit more. The largest single session in window is 1.4 MB of JSONL (today's email pipeline build); three sessions exceed 5 MB. You operate primarily in two windows: morning Brussels time (peak hour 9–11 UTC) and evening (peak 19–22 UTC). Median user response time is 72.5s — you're not babysitting, you're checking in.
Multi-clauding nearly tripled vs. the prior window (5 → 22 overlap events). Half your sessions now overlap with at least one other — a sign you've gotten comfortable spawning a side-session for unrelated lookups while a long build runs.
-root alone. Largest: 16 MB (April 4, mixed multi-VPS work).
182 sessions across 30 days. A handful are worth calling out for what they reveal about how you're operating now — especially today's email pipeline, which is the cleanest example yet of the new "spec → subagent → review → ship" workflow.
email_ingest.py (~900 lines, self-contained — does not import bot.py) plus tests/test_email_ingest.py with 62 passing checks. Triggered on a claude-ingest[:company] subject keyword (you tried Gmail labels first, the UX failed first-contact testing, you switched mid-build). Includes an Outlook-forward parser that walks the deepest nested original sender, <mailto:..> cleanup, a 20 KB image gate (5 KB at first, bumped after a WindEurope banner snuck through), company override (cloos|yaskawa|teqram|iemants|general), body-SHA1 content dedup with a 4-doc backfill of legacy ChromaDB entries, and a DST-aware hourly cron that gates by TZ=Europe/Brussels date +%H at 08/12/18 BT. Failure tracking: 3 failed cycles → claude-ingest-failed label + Telegram alert.bot-dev sub-agent (build → test → image-gate iteration), iterative course-corrections grounded in real-world testing rather than spec-perfection (label → subject, 5 KB → 20 KB, three follow-on body-cleanup fixes), and rollback discipline (vault + ChromaDB + Gmail labels snapshotted then restored before re-processing). The intentional duplication of the Gemini analyzer is documented for future unification in project_email_ingest_unification.md — debt logged, not hidden.
## DD/MM/YYYY + ### Company headers and stores date / company / week_num as metadata, and a hybrid memory search with a +0.15 keyword boost when company names match in tags or content. Practical wins, not academic: vault_search now returns the right Yaskawa entry when you query "ring connections 25380" instead of the closest semantic neighbor.qc_ndt_report tool now generates three artifacts in one call: Markdown summary, fpdf2 PDF with Liberation Sans + embedded photos, and an openpyxl XLSX from a real inspection-report template (in vault/excel_example/). The XLSX cross-references issues in section 7 to evidence in section 10 with paired left/right photos and inspector-style descriptions — close enough that gmail_send with attachments ships all three to the client without manual edits. Active on DAVIT CRANES 25380 (Seasight, 224 photos) and 27390 germannbridge./root/health-check.sh runs every 5 minutes against all 5 VPSes (Main, QC, Website, Yaskawa, Cloos), auto-restarts failed services, and alerts via Telegram with a 30-min cooldown to avoid alert spam. Daily security summary at 08:00 UTC. Backup-age checks gated to once-daily at 09:00 UTC (30h threshold) so they don't false-fire on the 24h cron skew. UFW + fail2ban enabled. The original report's "wrong VPS" friction class has effectively gone away thanks to ssh aliases.The friction classes have shifted. The old "wrong VPS" and "non-existent commands" issues have largely resolved (ssh aliases + a much fuller CLAUDE.md). New failure modes are about scale — duplicated code, oversized sessions, and lessons that need codifying because they keep being relearned.
vault_index_file exists in 4 separate copies; _prune_stale_* in 2. Today's email pipeline intentionally added a sixth Gemini-analyzer copy with documented unification trigger (project_email_ingest_unification.md) — debt logged, not hidden. The risk: a fix to one copy doesn't propagate.feedback_duplication_debt.md warns: "don't perpetuate while 'fixing'; unify names or extract first."vault_indexing.py extraction (~1.5–2h, playbook in project_next_vault_indexing_extraction.md) collapses 4 copies of vault_index_file + 2 copies of _prune_stale_*.feedback_*.md — explicit corrections to recurring Claude behavior. Each one is a lesson learned the hard way that cost real time before being codified. Notable: feedback_persist_tests.md (3 test suites deleted "after they passed" — now codified rule: tests go in tests/, always). feedback_adaptive_thinking_config.md (the field is output_config.effort, not budget_tokens — verified against Anthropic docs 2026-04-05).feedback_claude_code_model.md: bots shelling out to claude CLI must use Opus 4.6 (Max plan, no API cost); Sonnet downgrade only applies to direct API calls.feedback_api_vs_max_billing.md: the main bot uses direct API (billed per token), NOT Max — Max only covers claude CLI subprocess path.feedback_gemini_models.md: vision/content uses Gemini 3 Flash, never 2.5 Flash.

The 99.9% cache-hit rate softens the cost, but past ~5 MB you're paying real latency every turn.overloaded_error from a prior attempt — likely a session-size symptom.systemctl status on a non-running service), and the occasional Gemini API 503. Almost no "wrong VPS" or "command not found" errors — those got designed out by the ssh aliases and CLAUDE.md inventory./root/.config/google/ as a one-time setup; sed-over-SSH was replaced by writing files locally then scping.Just copy this into Claude Code to add it to your CLAUDE.md.

bot-dev subagent with a tight spec, then review and iterate.bot-dev dispatches in 30 days.Use the bot-dev subagent. Build a new self-contained module at /root/develop/telegram_connection/.py that does X / Y / Z. Constraints: do NOT import bot.py, write tests in tests/test_.py before declaring done, log any intentional duplication of existing helpers in a project_*_unification.md memory file. Report back with a summary and file paths only. feedback_*.md note in ~/.claude/projects/-root/memory/.I just had to correct you twice on . Write a feedback_.md memory file in /root/.claude/projects/-root/memory/ with: 1) the wrong behavior, 2) the correct behavior with citation, 3) why this matters in our codebase. Then save it to ChromaDB with tags=feedback, --priority 5. Before we re-run the : snapshot the current state of , dump the ChromaDB to a JSON, and save the current Gmail label list. Save all three to /tmp/snapshot-$(date +%s)/. Then run the pipeline with content-hash dedup against existing docs — don't delete first. ssh website / ssh yaskawa / ssh cloos-bot / ssh qc-bot — no IP addresses in prompts.~/.ssh/config + a CLAUDE.md inventory mean Claude knows which box runs what. Side-effect: prompts are shorter and less error-prone — "ssh yaskawa to check the rosbot logs" beats "ssh [email protected]".bot-dev subagent's tight build-test-report loop.You're past the "build the infrastructure" phase. Three concrete projects on the active list that the next 30 days could ship.
vault_index_file lives in 4 files; _prune_stale_* in 2. You have a written playbook (project_next_vault_indexing_extraction.md), tests in place, and a ~1.5–2h estimate. This is the cleanest "Plan → Explore → bot-dev in a worktree" candidate in the repo. Doing it well sets the pattern for the email-pipeline → bot.py unification later.git worktree add ../telegram_connection-extract-vault-indexing), dispatch Plan to draft the module API from the existing 4 callsites, then bot-dev to extract, leave the playbook open in the chat as the success criterion.debugger subagent on the existing micro-ROS Agent logs to baseline the current behavior before adding the FPX motion layer. Keep a project_yaskawa_phase2.md running playbook so the inevitable hardware-related re-runs don't lose state.email_ingest.py with a documented unification trigger in project_email_ingest_unification.md. When the next ingest variant lands (Slack? webhooks?), that trigger fires and you have a clean 3-way merge to do. The same worktree + Plan + bot-dev pattern as vault_indexing.py applies.feedback_duplication_debt.md says exactly this.claude-ingest[:company] subject keyword after one round of real-world testing on Arne's phone. The 5 KB image gate became 20 KB after a WindEurope banner snuck through. Three more body-cleanup fixes followed once forwarded Outlook chains showed their actual mess. Spec perfection is a myth; iterative course-correction is the actual workflow. The whole pipeline shipped, tests green, in one session.
