# Post-Optimization Adversarial Benchmark Report

**Approach:** Actively attempted to disprove every optimization. Tests designed to find regressions, not validate success.

---

## 1. Skills

### 1a. Disabled Skills: On-Demand Loading

**Test:** Call `skill_view("cloudflare-workers")` on a skill in the disabled list.

**Result:** ✅ `skill_view()` returns error: *"Skill 'cloudflare-workers' is disabled. Enable it with `hermes skills` or inspect the files directly on disk."*

**Verdict: REGRESSION DETECTED**

| Aspect | Status |
|--------|--------|
| `skill_view()` on disabled skill | ❌ Blocked |
| `read_file()` on disabled skill's SKILL.md | ✅ Works |
| Content integrity | ✅ 28KB intact on disk |

**Severity:** Low. The skill library audit docs claimed disabled skills are loadable on-demand via `skill_view()`. In Hermes v0.16.0, this is not the case — the tool actively blocks loading. **Workaround:** Use `read_file()` to read the SKILL.md directly from `~/.hermes/skills/<category>/<name>/SKILL.md`. This is one extra step but the content is fully accessible.

**Root cause:** Hermes v0.16.0 changed `skill_view()` behavior to reject disabled skills. The skill-library-audit reference file was written for an earlier version.

### 1b. Compacted Skills: Functionality

**Test:** Load each of the 5 compacted skills and verify they contain usable guidance.

| Skill | Size | Sections | Verdict |
|-------|------|----------|---------|
| system-administration | 2,865B | When-to-use ✅, Commands ✅, Pitfalls ✅ | PASS |
| local-model-fleet-management | 2,209B | ✅ Complete | PASS |
| hermes-diagnostics | 2,982B | ✅ Complete | PASS |
| llama-swap | 2,560B | ✅ Complete | PASS |
| llama-cpp | 2,579B | Commands ✅, Pitfalls ✅ — **When-to-use ❌** | PASS (minor) |

**Verdict:** PASS with 1 minor finding. `llama-cpp` SKILL.md is missing a dedicated "When to Use" section. It has commands and pitfalls, which is functional. The references/ directory (11 files) contains the full detail. A model reading this skill would still get usable guidance but wouldn't see when to apply it.

**Severity:** Low. The references/ directory fully compensates.

### 1c. Conditional Activation: Access Gating

**Test:** Can I still access skills with `requires_toolsets` metadata?

| Skill | Conditional | Accessible |
|-------|------------|------------|
| android-apk-analysis | `requires_toolsets: [terminal, file]` | ✅ |
| stremio-scraper-pipeline | `requires_toolsets: [terminal, web]` | ✅ |
| unspooled-tv-development | `requires_toolsets: [terminal, file]` | ✅ |

**Verdict:** PASS. All 3 tested skills load via `skill_view()` without error. The conditional activation metadata does not prevent skill_view() from working — it only controls whether the skill is auto-loaded into the system prompt.

---

## 2. RepoMap

### 2a. Exploration Overhead Reduction

**Test:** Find `auto-model-switch.py` using brute force `find` vs RepoMap.

| Method | Time | Result |
|--------|------|--------|
| Brute force `find ~ -name 'auto-model-switch.py'` | 1.287s | 4 paths found |
| `repo-map.py ~/.hermes/scripts --budget 512` | 0.092s | ✅ Found in structured output |

**Verdict:** PASS. RepoMap is **14x faster** for targeted directory exploration. It also provides context (file type, line count, language) that brute force doesn't.

### 2b. File Discovery Accuracy

**Test:** Find `RealDebridClient.kt` in Unspooled project using RepoMap at various budgets.

| Budget | Files | RealDebridClient found? |
|--------|-------|------------------------|
| 1024 | 85 | ❌ Not included (ranked lower) |
| 2048 | ~163 | ✅ Included |

**Verdict:** PARTIALLY PASS. At the default 1024 budget, the model gets 85 ranked files but may miss specific obscure files. This is expected behavior — the model can increase budget to 2048 when it needs deeper coverage. The file IS discoverable, just requires a higher budget.

**Severity:** Low. This is a feature of the ranking system, not a bug. The model should run with a higher budget when it needs full coverage.

## 3. Profiles

### 3a. Profile Integrity

| Profile | SOUL.md | config.yaml | profile.yaml | Size |
|---------|---------|-------------|-------------|------|
| coding | ✅ | ✅ | ✅ | 1,892B |
| cloud | ✅ | ✅ | ✅ | 878B |
| research | ✅ | ✅ | ✅ | 513B |
| telegram | ✅ | ✅ | ✅ | 513B |

### 3b. Behavioral Differentiation

**Test:** Verify coding profile is VRAM-aware, cloud profile is speed-optimized.

| Content | Coding | Cloud |
|---------|--------|-------|
| VRAM mention | ✅ "11GB VRAM constraint" | ❌ |
| execute_code-first | ✅ "Use execute_code for mechanical batch work" | ❌ |
| delegate_task-first | ❌ | ✅ "Use delegate_task for reasoning-heavy subtasks" |
| 128K context mention | ✅ "32K-64K effective context" | ✅ "128K+ context" |
| RepoMap instruction | ✅ | ❌ |
| Anti-filler rules | ✅ | ✅ |
| Few-shot tool patterns | ✅ | ❌ |

**Verdict:** PASS. Profiles are clearly differentiated. Coding contains local-model-specific guidance (VRAM, context limits, execute_code). Cloud contains reasoning-model guidance (128K context, delegate_task). Research/telegram are intentionally minimal.

---

## 4. Delegation Routing

**Test:** Verify `delegation.provider` and `delegation.model` are set to flash model.

| Key | Value |
|-----|-------|
| `delegation.provider` | `deepseek` |
| `delegation.model` | `deepseek/deepseek-v4-flash` |

**Verdict:** PASS. Config verified via YAML parser. The inline regex parser from the earlier benchmark had a bug — YAML-parsed value is correct.

---

## 5. Memory

**Test:** Verify USER.md is below limit and writes function.

| Metric | Value | Status |
|--------|-------|--------|
| USER.md size | 1,145B | ✅ |
| user_char_limit | 2,500 | ✅ |
| Utilization | 45.8% | ✅ |
| Writes unblocked | Yes | ✅ |

**Verdict:** PASS. USER.md is at 46% capacity. Writes are unblocked. No memory regressions.

---

## 6. Tool Patterns in SOUL.md

| Pattern | Present | 
|---------|---------|
| Diff-editing preference | ✅ "Prefer targeted edits (diff, patch, SEARCH/REPLACE)" |
| execute_code for mechanical work | ✅ "saves 80%+ tokens on no-reasoning-needed work" |
| Anti-filler rules | ✅ "Never start with Great!, Certainly!, Of course!" |
| Batch tool calls | ✅ "Call as many independent tools as reasonably needed" |
| RepoMap instruction | ✅ "Run repo-map.py before exploring unfamiliar codebases" |

**Verdict:** PASS. All 5 patterns present in main SOUL.md.

---

## 7. Compression Threshold

**Test:** Verify `compression.threshold` is 0.50.

| Key | Value | Status |
|-----|-------|--------|
| `compression.threshold` | 0.5 | ✅ |
| `compression.enabled` | True | ✅ |
| `compression.target_ratio` | 0.15 | ⚠️ May be too aggressive |

**Verdict:** PASS (with note). The threshold change from 0.35 to 0.50 is correct — it matches the official Hermes default. The `target_ratio: 0.15` means compression targets 15% of the threshold value, which is 0.15 × 128K = ~19K tokens preserved during compression. This was not changed — it's pre-existing from before this audit.

**Severity of pre-existing setting:** Low. 19K token preservation is adequate for most sessions. If you notice context loss during very long sessions, consider raising `target_ratio` to 0.20 or 0.25.

## 8. Prompt Size (Estimated)

| Component | Estimated Tokens |
|-----------|-----------------|
| SOUL.md | ~544 (2,177B ÷ 4) |
| MEMORY.md | ~450 (1,800B ÷ 4) |
| USER.md | ~286 (1,145B ÷ 4) |
| Core system prompt (built-in) | ~3,000-5,000 |
| Tool schemas (no stub_mode) | ~7,000-8,000 |
| Skills manifest index | ~3,000-5,000 |
| **Estimated total** | **~14,000-19,000** |

**Note:** Cannot measure actual prompt tokens from within the running agent. These are estimates based on file sizes ÷ 4 tokens/char.

---

## 9. Cumulative Severity Assessment

| Finding | Severity | Impact | Fix |
|---------|----------|--------|-----|
| Disabled skills blocked from skill_view() | Low | Extra step to load (read_file works) | Use read_file() to load disabled skills directly |
| llama-cpp missing "When to Use" section | Low | Minor usability issue | Add section to SKILL.md |
| compression.target_ratio: 0.15 may be aggressive | Low | Possible context loss on very long sessions | Consider 0.20 if sessions >200 turns |
| No stub_mode in v0.16.0 | Medium | 46% per-turn tool overhead | Wait for PR #48622 to merge |

**No critical or high-severity regressions found.**
