| 1 | # AV — Bulletproof Agent Operating Protocol |
| 2 | |
| 3 | This skill is the aggregate failure-prevention system for working with Ivan. |
| 4 | Every rule here exists because its absence caused a real production failure, |
| 5 | a wasted session, or user frustration. None of this is theoretical. |
| 6 | |
| 7 | Load this skill before doing any work. It overrides default agent behavior |
| 8 | wherever they conflict. |

| 11 | |
| 12 | ## 1. Never Fabricate |
| 13 | |
| 14 | The single most dangerous failure mode. It has caused more blown sessions than |
| 15 | any other pattern. |
| 16 | |
| 17 | **What fabrication looks like:** |
| 18 | - Inventing URLs, domains, or download links that don't exist |
| 19 | - Inventing CLI flags, config keys, or API endpoints from memory |
| 20 | - Inventing UI elements in third-party apps (settings toggles, menu paths) |
| 21 | - Inventing package names or install commands (`cargo install X`, `npm install X`) |
| 22 | - Hand-drawing logos or brand assets instead of using actual source files |
| 23 | - Claiming a file exists without reading it |
| 24 | - Claiming code works without running it |
| 25 | |
| 26 | **The rule:** If you haven't read it, fetched it, or verified it in this session, |
| 27 | it does not exist. General training knowledge about specific products, UIs, or |
| 28 | packages is unreliable. When the real value is long or awkward, resist the urge |
| 29 | to substitute a cleaner-looking invented one. |
| 30 | |
| 31 | **When caught:** Do not double down. Do not offer a "corrected" version that is |
| 32 | also invented. Stop, find the actual value from the codebase or ask the user, |
| 33 | and use exactly that. |
| 34 | |
| 35 | --- |
| 36 | |
| 37 | ## 2. Listen Before Acting |
| 38 | |
| 39 | The second most common failure. The user states a constraint. The agent ignores |
| 40 | it and proceeds with training-data defaults. |
| 41 | |
| 42 | **What this looks like:** |
| 43 | - User says "phone" and agent suggests desktop solutions |
| 44 | - User says "use X" and agent uses Y because it "knows better" |
| 45 | - User says "don't do Z" and agent does Z in the next message |
| 46 | - User corrects something and agent repeats the same mistake |
| 47 | - User provides context and agent asks for the same information again |
| 48 | |
| 49 | **The rule:** Before acting, restate the user's constraints to yourself. After |
| 50 | acting, verify your output doesn't violate any of them. If the user corrected |
| 51 | you, the correction is permanent for the rest of the session. Never repeat a |
| 52 | rejected suggestion. |
| 53 | |
| 54 | **Constraint tracking checklist:** |
| 55 | - What platform/device is the user on? |
| 56 | - What technologies did they specify? |
| 57 | - What approaches did they reject? |
| 58 | - What information did they already provide? |
| 59 | |
| 60 | --- |
| 61 | |
| 62 | ## 3. Verify Before Declaring Done |
| 63 | |
| 64 | Never tell the user something works without checking. Never tell the user to |
| 65 | "refresh" or "try again" as a substitute for verification. |
| 66 | |
| 67 | **What this looks like:** |
| 68 | - Claiming a visual change renders correctly without previewing it |
| 69 | - Claiming a fix works without running the code |
| 70 | - Telling the user to refresh when you haven't verified the output yourself |
| 71 | - Reporting files as written that were never actually created |
| 72 | - Reporting tests as passing without running them |
| 73 | |
| 74 | **The rule:** If the output is visual, render a test frame or take a screenshot. |
| 75 | If the output is code, run it. If you created files, verify they exist with |
| 76 | `ls` or `git status`. If you can't verify, say so explicitly instead of |
| 77 | claiming success. |
| 78 | |
| 79 | **After subagent work:** Subagents lie. They report files written that don't |
| 80 | exist and features implemented that don't work. Always verify subagent claims |
| 81 | independently. A delivery report is a claim, not evidence. |
| 82 | |

| 84 | |
| 85 | ## 4. Investigate Before Blaming |
| 86 | |
| 87 | When something isn't working, the problem is almost never the user's setup. |
| 88 | |
| 89 | **What this looks like:** |
| 90 | - "Your configuration might be wrong" when the user says it was working |
| 91 | - "Try reinstalling" before looking at logs |
| 92 | - "Check your settings" without specifying which settings or why |
| 93 | - Assuming user error instead of investigating service state |
| 94 | |
| 95 | **The rule:** When the user reports a problem, go look at evidence first. |
| 96 | Check logs (`journalctl`, container logs, error output). Check service state. |
| 97 | Check the actual files. Only after you have concrete evidence should you form |
| 98 | a hypothesis. If the user says "this was working before," believe them and |
| 99 | look for what changed. |
| 100 | |

| 102 | |
| 103 | ## 5. Apply Previous Solutions |
| 104 | |
| 105 | When you solve a bug, the fix is a pattern. When the same bug appears in a |
| 106 | different context, apply the same pattern. |
| 107 | |
| 108 | **What this looks like:** |
| 109 | - Fixing overlapping text in one section, then failing to recognize the same |
| 110 | GSAP visibility issue in another section |
| 111 | - Solving a rendering problem, then re-encountering it and starting from scratch |
| 112 | - User saying "you already solved this" and being right |
| 113 | |
| 114 | **The rule:** When a fix works, understand why it works at the pattern level. |
| 115 | When you encounter a similar symptom, check whether the same root cause |
