Every rule below came from something breaking first.\n\nI told a supplier their margin had dropped eight percent. On a call. With confidence.\n\nIt hadn’t. My agent was reading a CRM cache from eight days earlier and never thought to mention that.\n\nIt didn’t lie to me. It just never learned to say how old its own information was.\n\nEvery one of these rules has a Tuesday behind it. That’s the only reason this list is worth your time - nobody sat down and reasoned these out. They’re scar tissue.\n\nAt the bottom, you will get: The Personal Agent Build Kit - my actual Constitution template, my filled-in autonomy matrix, and the file routing table.\n\n> Fifteen of these took me four of the six weeks to learn. They're separated at the end, in build order. If you read nothing else in this issue, you must read those fifteen and apply them before you write a single file.\n\n## Old Way → New Way\n\nOld: System prompt → New: Constitution that explains why the rules exist\n\nOld: One giant memory file → New: Domain-separated markdown with an index\n\nOld: Use this skill when relevant → New: Explicit trigger phrases, not for clauses\n\nOld: Ask permission for everything → New: Autonomy matrix mapped to reversibility\n\nOld: Correct it in chat → New: Every correction becomes a permanent spec rule\n\nOld: Hope it stays consistent → New: Hooks enforce, regression tests verify\n\n## Step-by-Step Walkthrough\n\nThirteen categories. Each one opens with the failure that produced it.\n\n![](https://pbs.twimg.com/media/HOECoORbEAAM5kD.jpg)\n\n## Foundation & Identity\n\nWhat broke: It hit a situation my system prompt didn’t cover, invented a policy, and applied it confidently.\n\n1. Give it a name, a voice, and a role. “Always first person. Direct. Data before emotion. No filler. No trailing summaries.” This kills hundreds of micro-decisions per session and gives you consistency you can audit.\n\n2. Define your principal deeply. How do they decide? What frustrates them? “Wants alternatives with scoring, not one recommendation. Hates vague answers.” This shapes output more than any prompt trick.\n\n3. Build a Capability Map and a Component Map - separately. Capability Map: what can it do. Component Map: how is it built. Conflating them produces a document nobody can use by month three.\n\n4. Build a THINK vs. DO model into its identity. Uncertain → THINK: analyze, draft, prepare, but don’t block waiting for permission. Clear → DO. A paralyzed agent is a useless agent.\n\n![](https://pbs.twimg.com/media/HOEC2h6akAAYZfQ.jpg)\n\n## Memory System\n\n5. Use flat markdown files, not a database. For a personal agent, markdown beats vector DBs. Readable, greppable, git-trackable, directly loadable.\n\n6. Build session_hot_context.md with a TTL. What was in progress? What decisions were pending? Loaded at session start, expired after 72 hours. Stale hot context is worse than none - it presents old state as current.\n\n7. Build daily_note.md as an async brain dump. Thoughts, voice-to-text, half-ideas, dumped throughout the day. The agent routes them to their correct homes during sync.\n\n8. Build hypotheses.md with confidence levels. “Supplier X may be at capacity (65% confidence).” A suspicion layer that persists across sessions and gets validated over time. Age them out at 30 days, or they become noise.\n\n9. Build a WAITING_ON_ME queue. Everything the agent prepared and needs your decision on, timestamped. Items over 7 days get a nudge, over 30 days auto-close.\n\n10. Build user_behavioral_profile.md. What do you approve fast versus slow? What do you decide intuitively versus analytically? The agent uses this to choose “act autonomously” or “escalate.” It gets uncomfortably accurate.\n\n11. Mirror your memory folder to cloud storage. If your machine dies, the agent loses months of accumulated knowledge. Dropbox, Drive, S3 - doesn’t matter. This isn’t backup, it’s survival.\n\n![](https://pbs.twimg.com/media/HOEDK6FbMAAFv0B.jpg)\n\n## Knowledge Library\n\n12. Organize the library by cluster, not by date. Domain folders: sales_negotiation/, strategy/, supply_chain/, plus an INDEX.md hub. A flat dump of PDFs is a graveyard. A structured library is a live resource.\n\n13. Build a .brief.md per source. One page per book: core thesis, 3–5 key concepts, application examples for your context.\n\n14. Build a 3-question Quality Gate before citing. Does it add something you wouldn’t reach from first principles? Does it reframe rather than confirm? Would removing it leave a gap? Two of three → cite. Otherwise stay silent.\n\n15. Treat “silent consultation” as a valid output. You checked the library, applied the insight, didn’t mention it. The output is sharper. After all, you consulted it and cleaner because you didn’t cite it.\n\n16. Pre-wire knowledge stacks per project and per relationship. Two or three sources per active project, two or three per key contact. Loaded automatically when those contexts are active.\n\n![](https://pbs.twimg.com/media/HOEDfhlaYAAtfEX.jpg)\n\n## Skills Architecture\n\n17. Build each skill as a directory with a SKILL.md spec. Not inline prompts. A folder with explicit triggers, outputs, and NOT FOR clauses. Skills become composable and replaceable without touching core identity.\n\n18. Distinguish skills from agents. Skills are procedural: defined workflow, predictable output. Agents have domain expertise and make judgment calls. Skills orchestrate; agents decide. Mixing them produces undebuggable behavior.\n\n19. Build a skills registry with usage tracking. Name, trigger, purpose, last used, KPI. Quarterly audit: zero usage in 60 days means better triggers or deprecation. Dead skills are a maintenance burden with no upside.\n\n20. Build an /iterate skill for multi-pass refinement. PRODUCE → CRITIQUE with score and gaps → REFINE → repeat. Stop at 9/10 or at plateau.\n\n21. Build output intensity levels into every skill. MINIMAL, STANDARD, FULL. A five-page analysis on a yes/no question is a skill design failure. Intensity should match the weight of the question.\n\n22. Build a visible Outbox folder. Deep structures organize well and surface terribly. Every output also gets copied to a flat Outbox/. Clear it weekly. Otherwise you’re navigating a tree to find what was just made.\n\n![](https://pbs.twimg.com/media/HOEDsiMaIAAyBV9.jpg)\n\n## Multi-Agent & Council\n\n23. Build an explicit dispatch matrix. A table: signal in request → agent to dispatch. Pricing/supplier/shipping → procurement. Email/customer/pipeline → sales. Pattern-match routing mechanically instead of reasoning about it.\n\n24. Run parallel agents for tasks that split naturally. New supplier analysis spawns a procurement agent for pricing and a research agent for due diligence at the same time. Richer output, same elapsed time.\n\n25. Brief delegated agents like a smart colleague who just walked in. Not “research this.” Pass what you know, what you’ve ruled out, what decision it informs, the risk level. The quality gap between a briefed agent and a one-liner agent is not subtle.\n\n26. Force agents to commit to a verdict. Require VERDICT: PROCEED / PAUSE / ESCALATE with a confidence level. An agent that presents data without a position hands the decision back to you, defeating the point of delegating.\n\n27. Structure Council as 3 rounds, not a free-for-all. Round 1: isolated parallel positions. Round 2: cross-examination. Round 3: vote with mandatory dissent recorded. The dissent tells you exactly what you’re choosing to ignore.\n\n28. Make two agents mandatory anchor voters. The Strategist (long-horizon, second-order effects) and the Devil’s Advocate (finds holes) join every Council. Five procurement experts agreeing is an echo chamber, not a decision.\n\n29. Keep a devil’s advocate as a standalone tool. Run adversarial review before important external comms, irreversible decisions, and large purchases. It catches “sounds right, is wrong” better than any other technique.\n\n30. Give Council a clear trigger and respect its cost. Single agent for clear-domain reversible calls. Council only when there are two-plus valid paths AND meaningful irreversibility. Council is expensive - offer it, don’t default to it.\n\n31. Build structured handoffs between agents. “Analysis complete. Key finding: X. Risks: Y. Your job: Z.” Handoff is context transfer, not just task completion. Without it, every agent starts cold.\n\n32. Have a catch-all fallback and log what it handles. When no specialist matches, general purpose takes it. The catch-all log is a live map of gaps in your specialist coverage - and your development backlog.\n\n![](https://pbs.twimg.com/media/HOED7kNbcAA4ac6.jpg)\n\n## Session Management\n\n33. Build symmetric start and end protocols. /start-session loads context, checks the queue, reports delta. /end-session Saves context, syncs tasks, archives outputs. Asymmetry causes state drift that compounds over weeks.\n\n34. Build three levels of session closure. Light: transcript and summary. Medium: plus memory sync and task queue. Full: plus daily report and autolearn. One expensive “end” gets skipped. Tiered means you always do something.\n\n35. Build a session-start hook at the shell level. A script that injects current time, machine identity, day of week, phase of day. The agent always knows context without you typing it. One-time setup, daily dividend.\n\n36. Check inbox delta and red alerts at session start. “Since last session: 4 new emails, 2 tasks updated.” Plus P0 items due today and contacts silent over 14 days. Surface it automatically - don’t make the user ask.\n\n37. Check scheduled automation health at session start. Did overnight tasks run? Any errors? A scheduled task that silently stopped is a silent degradation you won’t find until something breaks.\n\n38. Track correction count across sessions. Correct the same thing three times across different sessions, and you’ve found a missing rule in your spec. Chat corrections disappear. Spec corrections persist.\n\n![](https://pbs.twimg.com/media/HOEEGcuaUAA5TT4.jpg)\n\n## Decision Authority\n\n39. Let the agent earn expanded autonomy with evidence. Handle a task class N times with zero corrections, then propose a promotion to a higher autonomy level. Earned autonomy is more durable than granted autonomy.\n\n40. Build a principal hierarchy for rule conflicts. Root config > skill spec > agent instructions > session context. When a skill says “save to X” and root config deprecated X, root config wins. Document the order.\n\n41. Build a pre-send gate for high-stakes external comms. Above a value threshold, route through adversarial review before sending. One extra round-trip catches the hardest failure to recover from: confident, well-written, factually wrong.\n\n42. Document absolute forcing functions - unconditionally. Financial commitments above threshold, HR communications, irreversible deletes: always confirm. Hard-code them. Their entire value is that context and urgency can’t override them.\n\n![](https://pbs.twimg.com/media/HOEEQaXbcAAj2Dg.jpg)\n\n> Halfway. If you've been skimming, this is the section to actually read. Decision authority is where an agent either becomes useful or becomes a liability.\n\n## Proactive Initiative\n\n43. Build a typed proactive observation system. Classify every unsolicited observation: BIZ, OPS, DEV, PAT. “I noticed something” is noise. A typed observation with a confidence score and a proposed action is signal.\n\n44. Build hard anti-spam rules into the proactive layer. Max one observation per response, three per session, minimum confidence threshold, never before answering the actual question. Without limits, proactive becomes annoying.\n\n45. Build a /spark mode that lifts all suppression. In spark mode, every high-confidence observation surfaces at once. The proactive layer runs all week quietly; spark mode is how you harvest it intentionally.\n\n46. Build an ideas log for parked observations. Suppressed observations get written to ideas_log.md instead of discarded. Weekly review - some become relevant as context shifts. Good ideas shouldn’t die from bad timing.\n\n47. Build state-triggered alerts as rules, not LLM inference. Deal blocked over 7 days, contact silent over 14, hypothesis above 95% without action. These fire reliably because they’re rules. The LLM generates insight; rules generate alerts.\n\n48. Have the agent maintain its own development backlog. Repeated corrections, a manual step done five times, a missing skill, a zero-usage tool - auto-added to development_backlog.md. This beats top-down planning every time.\n\n![](https://pbs.twimg.com/media/HOEEgPOaEAAyTvk.jpg)\n\n## VIP Management\n\n49. Build a tiered contact registry with handling rules per tier. T1 strategic: full profile loaded before any interaction, silence-tracked, knowledge stack pre-wired. T2 operational: profile before significant interactions. T3: known, not deeply profiled.\n\n50. Make “load VIP profile before communication” a reflex. Before any output involving a T1 contact, load the actual profile file - not session memory. Profiles hold preferences, relationship status, sensitivities. Session memory degrades; files don’t.\n\n51. Track silence per T1 contact with thresholds. Log last meaningful interaction. Surface silence over 14 days with active business, over 30 days without. The agent brings these to you, not the other way around.\n\n52. Build knowledge stacks per key relationship. Two or three sources per T1 contact on how to communicate with them. Cross-cultural contacts get culture frameworks. Load for significant comms only, not every message.\n\n53. Build proactive VIP triggers into session start. Any T1 silent over 14 days with an open deal? Any T1 response queued over 3 days? High-value relationships degrade when you’re busy - exactly when the agent should pull the thread.\n\n![](https://pbs.twimg.com/media/HOEEpxfawAANQJs.jpg)\n\n## Output & Communication\n\n54. Enforce pre-tool brevity as a hard rule. One sentence max before any tool call. No hypotheses before data, no three-sentence preambles. “Checking the supplier file.” Then check it. Biggest daily quality-of-life win on this list.\n\n55. Build a “Next N Steps” protocol with anti-bias rules. Ranked options with scores after every decision - and at least two must be “don’t,” “wait,” or “delegate.” This actively fights action bias and sycophantic agreement.\n\n56. Build a separate “single best action” format for technical outputs. Audits, debugging, planning: one action, why it matters, risk if skipped, copy-paste prompt. Not every output needs a menu. Never mix the two formats.\n\n57. Visually disambiguate your three importance signals. Action scoring, task priority, and VIP tier each get their own visual grammar - squares versus circles versus name markers. Never mix. Dense updates then parse in seconds.\n\n58. Never let the agent summarize what it just did. “In summary, I have done X, Y, Z” - cut it. If you can read the output, you don’t need the meta-commentary. Roughly 20% shorter responses, zero information lost.\n\n59. Force a recommendation, not a menu. Recommend one, score the others, explain why. Options without a recommendation hand the decision back to you. The agent’s job is to do the decision work first.\n\n60. Make every file reference clickable. A tiny local server (localhost:7777/open?path=X) opens your file manager at any path. Plain text paths are dead weight. One-time setup, permanent improvement.\n\n61. Build “minimal mode” as a one-word override. “Quick,” “briefly,” “just the answer” drops all structure and returns the direct answer. Richness is the default. You should never have to fight for a short reply.\n\n![](https://pbs.twimg.com/media/HOEE2P4aMAAtXJb.jpg)\n\n> Everything from here is what turns a working agent into one you don't have to babysit.\n\n## Files, Data & Integrations\n\n62. Enforce a No Root Files hard rule. Outputs go to workspace/YYMMDD/. Projects, knowledge, and memory each get their own home. The root is navigation, not storage. One exception becomes twenty within weeks.\n\n63. Build a routing table for every file type. Without a table, the agent uses reasonable judgment - and reasonable judgment produces seven different locations for the same file type over six months.\n\n64. Maintain a deprecated path mapping table. Document every rename: old/path → new/canonical/path. The agent substitutes silently. This is critical during a cloud-to-local migration where old paths are baked into dozens of skill files.\n\n65. Build explicit degraded mode for every integration. CRM down: cache under 24h use with a freshness note, over 24h flag STALE, over 7 days refuse and request sync. Design the failure path before you need it.\n\n66. Give the agent raw business data, not just summaries. I gave mine raw transaction CSVs, 2M+ rows. That turns a summarizer into an analyst - margin by supplier by category by quarter, with no lookup on my side.\n\n67. Build a decision tree for “where does this belong?” External counterparty and selling → sales deal. Buying → procurement deal. Deadline plus multi-step → project. Single action → task. No deadline → note. Otherwise your data model rots.\n\n68. Build a mobile channel with source tagging. A Telegram bot that tags every inbound message source: mobile. The agent switches output mode: two short paragraphs, no tables, no headers. Same intelligence, different profile.\n\n69. Cap mobile autonomy by source tag, not judgment. From mobile, autonomy is hard-capped at L2 regardless of the task. Never send externally, never take irreversible actions. The phone is an untrusted environment.\n\n70. Echo back every action taken from a mobile trigger. “Done: added task X. Created draft email to Y - not sent, waiting for your review at desktop.” This closes the loop when you can’t see the full output.\n\n71. Treat mobile inputs as potentially untrusted. A forwarded email can carry instructions disguised as your input. The agent reads intent but never executes instructions embedded in forwarded content. Rule, not judgment call.\n\n72. Build a fast path and a slow path per data source. API query is slow and rate-limited; local file dump is fast and cached. Default to fast, fall back to slow. Never let infrastructure latency block core function.\n\n![](https://pbs.twimg.com/media/HOEFIbJaEAAGaZf.jpg)\n\n## Automation & Quality\n\n73. Build an allowlist for safe read-only operations. Scan transcripts for operations you approve 100% of the time - reads, searches, status checks - and allowlist them. Friction should concentrate around genuinely dangerous actions.\n\n74. Build AUTOLEARN into your day-end routine. The agent scans the session and extracts structured learnings into memory files: new facts, hypothesis updates, corrections, patterns. Git-commit every run. Your log becomes a knowledge timeline.\n\n75. Build scheduled proactive tasks that run without you. Daily: P0 scan, contact silence, blockers. Weekly: memory audit, skill usage audit, hypothesis aging. The agent works while you sleep - but only if you design it to.\n\n76. Build error escalation ladders. Once → log. Three times in 7 days → surface. Five times → propose a fix, not a notification. Recurring errors should generate work items, not log entries.\n\n77. Build a regression test suite. A list of scenarios with expected outputs, run after any major identity or skill change. Fail a test it used to pass, and you’ve found a regression. Otherwise, config changes are untested deploys.\n\n78. Run a quarterly system audit. Memory consistency, routing accuracy, registry sync, scheduled task health, token efficiency, naming drift, authority coverage. Code review for your agent. Things drift.\n\n79. Audit your agent with a different model periodically. Upload your whole config to a different model and ask for a critical review. Different architecture, different blind spots. Ask: “What does this agent get wrong under time pressure?”\n\n![](https://pbs.twimg.com/media/HOEFQjabAAEG30Z.jpg)\n\n## Meta & Mindset\n\n80. Invest in the Constitution before the skills. It’s tempting to build more skills and more integrations. A well-written identity and authority document does more for reliability than ten new skills. Skills compound on foundation or not at all.\n\n81. Design for the 3 AM test. Would you be comfortable with this agent sending that email or editing that file at 3 AM unreviewed? Yes → autonomous. No → confirmation. Trust that gut check over any framework.\n\n82. Build a fail-open bias for memory loading. Unsure whether a file is relevant? Load it. Cost of extra context: a few tokens. Cost of missing context: a wrong answer. The asymmetry is obvious.\n\n83. Build a teaching capsule when onboarding a new domain. New tool or data source → the agent writes what it is, how it works, key concepts, example queries, common pitfalls, stored in knowledge/. The next session starts warm.\n\n84. Migrate cloud → local when you need real files. Cloud is great for rich context and fast iteration. Local unlocks file access, git, hooks, headless scheduled tasks, raw data. Start in cloud. Migrate when you hit the ceiling.\n\n85. The agent mirrors the quality of your own thinking. Before writing any instruction, ask whether you know exactly what you want. Vague spec, vague agent. Contradictory spec, contradictory behavior. It amplifies your thinking - it doesn’t fix it.\n\n![](https://pbs.twimg.com/media/HOEFaEjaEAAOjf8.jpg)\n\nThat's 85. The fifteen that actually hold the whole thing up are at the end.\n\n## The 15 That Matter Most\n\nI gave you 100. If you only ever do fifteen, do these - in this order. Every other rule on the list is an optimization on top of one of them.\n\n1. Write a Constitution, not a system prompt.\nEverything else is decoration on this. A list of commands has nothing to fall back on when the list runs out - and it always runs out. Principles let the agent reason through the edge case instead of inventing a policy.\n\n2. Separate hard rules from behavioral guidelines.\nHard rules are never overridden by context. Guidelines adapt. Mix them and the agent treats either everything or nothing as negotiable, and you won’t find out which until it matters.\n\n3. Define what the agent is NOT.\n“Not a summarizer. Not a yes-machine. Does not wait to be asked.” Five negative definitions do more against drift into generic helpfulness than fifty positive ones.\n\n4. Version your identity file in git.\nWhen behavior drifts, you need git blame on your configuration. Regressions trace to specific edits far more often than you’d expect. Without history, debugging identity drift is archaeology.\n\n5. Separate memory by domain, not by date.\nentities_people.md, entities_deals.md, hypotheses.md, task_queue.md. One file, one domain. Chronological dumps become unsearchable by week two.\n\n6. Build a MEMORY.md index.\nOne index listing every memory file with a one-line description. The agent loads the index first and pulls specific files on demand. This is what keeps context usage predictable as memory grows.\n\n7. Distinguish cache from source of truth, explicitly.\nYour local deals.md is a cache. The CRM is the truth. Mark every cache file with a last_sync: header, without exception.\n\n8. Always announce data freshness in outputs.\n“Data: CRM export from May 11, age 8 days.” One line on every output using external data. This is the rule that would have saved me from the 8% margin call.\n\n9. Write explicit trigger phrases into every skill.\nInference is a coin flip you run a hundred times a week; phrase matching fires reliably every time. Never leave activation to the model’s judgment.\n\n10. Write NOT FOR clauses into every skill.\n“NOT FOR: pricing decisions. NOT FOR: legal analysis.” This stops skill creep - the slow drift where everything gets routed to the wrong skill because it pattern-matched superficially.\n\n11. Build an explicit autonomy level matrix.\nL0 read. L1 write local. L2 tasks and calendar. L3 external messages. L4 financial. The agent knows exactly what it can do unsupervised. Without this, you get permission spam or unpleasant surprises, usually both.\n\n12. Map every action to reversibility, not risk.\nIrreversible actions need confirmation. Reversible actions need visibility, not approval. Calibrating on risk instead is what makes autonomy oscillate between useless and dangerous.\n\n13. Default to “THINK, don’t ask.”\n“Should I draft this?” wastes a round-trip. Draft it, show it, then ask about sending. Either way the work is done. This is the single biggest change in how the agent feels to work with day to day.\n\n14. Use hooks for anything that must be consistent.\nThe runtime executes hooks. The LLM does not. Memory can recommend; hooks enforce. If something must happen reliably every single time, it does not belong in a prompt.\n\n15. Treat every correction as specification debt.\nCorrect it in chat, and it disappears tonight. Correct it in the spec, and it persists forever. Correcting the same thing three times means you found a missing rule, not a stubborn agent.\n\n## Free Gift Delivery\n\nThe Personal Agent Build Kit\n\nDuplicate it to your own Notion and work through it in build order, not numerical order.
