Date: 2026-02-10 Version: v1.10.1 Scope: Measured impact of 3-phase token compression across all VBW instruction layers Method: 9 plans, 25 tasks, 23 commits, 80/80 QA checks across 3 sequential phases Verdict: VBW's per-session token footprint reduced by ~45-55% through aggressive instruction compression, artifact compaction, and reference consolidation -- saving an estimated 8,000-14,000 tokens per session
VBW v1.0.99 introduced 15 optimization mechanisms across 7 architectural layers (see vbw-1-0-99-vs-stock-teams-token-analysis.md). Those mechanisms optimized when and how content is loaded. This milestone optimized the content itself -- making every loaded byte carry more signal per token.
Three phases attacked three distinct token surfaces:
| Phase | Target | Before | After | Reduction |
|---|---|---|---|---|
| 1: Instruction Compression | 29 commands + 6 agents | 4,804 lines | 2,266 lines | 53% |
| 2: Artifact Compaction | 7 templates + 5 hooks + live artifacts | 1,918 lines | 1,378 lines | 28% |
| 3: Reference Diet | 17 reference files + CLAUDE.md | 1,913 lines | 591 lines | 69% |
The key insight: VBW v1.0.99 already controlled which files get loaded and when. But the files themselves were written in explanatory prose -- readable for humans, wasteful for models. Claude doesn't need "Please follow this protocol carefully:" before a bullet list. Cutting the prose cut the tokens.
Compounding effect: These savings multiply with VBW's existing optimization stack. Compressed commands loaded via disable-model-invocation were already cheap -- now the 8 always-on commands are cheaper too. Compressed agents loaded via model routing were already dollar-efficient -- now each spawn is also token-efficient. Every layer that was optimized for when to load now also benefits from less to load.
Before this milestone, VBW's instruction files were written in a readable, explanatory style. Every command included full context, rationale paragraphs, and example-heavy prose. This was fine during development but expensive in production.
| Layer | Files | Lines | Est. Tokens | Loaded When |
|---|---|---|---|---|
| Always-on commands (8 active) | 8 .md | 942 | ~3,200 | Every API request |
| Disabled commands (21) | 21 .md | 3,862 | ~13,100 | Only when invoked |
| Agent definitions (6) | 6 .md | 426 | ~6,400 | Each agent spawn |
| Templates (7) | 7 .md | 382 | ~5,700 | Plan/execute flows |
| Reference files (17) | 17 .md | 1,795 | ~27,000 | Backtick lazy-load |
| CLAUDE.md baseline | 1 .md | 118 | ~1,770 | Every API request |
| Live artifacts (STATE/ROADMAP/etc.) | ~6 .md | 431 | ~6,500 | Command invocations |
| Hook scripts (26) | 26 .sh | 1,105 | N/A (shell) | Zero model cost |
| TOTAL | 92 | 9,061 | ~63,670 |
Not all of this loads at once -- VBW's lazy-loading and disable-model-invocation already ensure only relevant content is read. But when content is loaded, it was fatter than necessary.
Goal: Rewrite all 29 commands and 6 agents in terse format Result: 4,804 → 2,266 lines (53% reduction) Commits: 8 (f93f294 through c22ae8d)
Replace prose with bullets. Remove rationale paragraphs. Compress conditionals into single-line guards. Convert verbose step descriptions to terse action items. Keep all functional behavior; strip all explanation.
Command guard pattern (every command):
# BEFORE (3 lines)
Before proceeding, check if the project has been initialized by looking
for the `.vbw-planning/` directory. If it doesn't exist, stop and tell
the user to run `/vbw:init` first.
# AFTER (1 line)
If no .vbw-planning/ dir: STOP "Run /vbw:init first."Agent instruction pattern:
# BEFORE (vbw-dev.md, 12 lines for deviation handling)
When you encounter a situation that requires deviating from the plan,
follow this protocol:
1. Document the deviation with a unique ID (DEVN-XX)
2. Explain what the plan specified
3. Explain what you're doing instead and why
...
# AFTER (3 lines)
Deviations: assign DEVN-XX ID. Record: {id, plan_said, doing_instead, why}.
Include in commit msg. Only deviate for: broken assumptions, missing deps,
scope conflicts, better approaches discovered during implementation.| Category | Files | Before | After | Reduction |

Goal: Audit and consolidate reference files, trim CLAUDE.md baseline Result: 17 → 8 reference files (53%), volume 1,795 → 497 lines (72%), CLAUDE.md 118 → 94 (20%) Commits: 8 (5a6011d through 3f6aaba)
Three-wave approach:
- Delete orphans (5 files nobody loads) and inline singles (3 files with exactly one consumer)
- Compress survivors (merge effort hub into sub-profiles, compress verification-protocol and handoff-schemas)
- Trim CLAUDE.md baseline and run final audit
| File | Lines | Disposition | Reason |
|---|---|---|---|
| vbw-brand.md | 334 | Deleted | Header says "NOT loaded into agent context" -- human-only doc |
| model-cost-evaluation.md | 121 | Deleted | Analysis artifact, zero references from commands/agents |
| deviation-handling.md | 108 | Deleted | Already fully inlined into vbw-dev.md during Phase 1 |
| checkpoints.md | 37 | Deleted | Only referenced by deviation-handling.md (orphan chain) |
| continuation-format.md | 42 | Deleted | Only referenced by checkpoints.md (orphan chain) |
| shared-patterns.md | 37 | Inlined | 4 patterns distributed into 20 consuming commands |
| memory-protocol.md | 163 | Inlined | Single consumer (implement.md) -- compressed to ~20 lines inline |
| skill-discovery.md | 182 | Inlined | Single consumer (init.md) -- compressed to ~25 lines inline |
| Total eliminated | 1,024 | 8 files removed |
Deviation noted (DEVN-01): Plan specified 12 commands needed shared-patterns inlining. Actual count was 20. All 20 received the same mechanical inline replacement.
| File | Before | After | Reduction | Method |
|---|---|---|---|---|
| effort-profiles.md (hub) | 100 | 0 | 100% | Content distributed into 4 sub-profiles, hub deleted |
| effort-profile-thorough.md | 19 | 33 | +74% | Absorbed hub content (self-contained now) |
| effort-profile-balanced.md | 17 | 31 | +82% | Absorbed hub content |
| effort-profile-fast.md | 17 | 29 | +71% | Absorbed hub content |
| effort-profile-turbo.md | 17 | 31 | +82% | Absorbed hub content |
| verification-protocol.md | 298 | 146 | 51% | Prose → terse tables, examples trimmed |
| handoff-schemas.md | 172 | 94 | 45% | Removed field tables (JSON examples ARE the schema) |
| Net change | 640 | 364 | 43% |
The effort profile sub-files grew individually but the hub file was eliminated -- a net reduction of 40 lines and the elimination of one level of indirection (commands no longer load a hub that points to a sub-profile; they load the sub-profile directly).

This analysis uses ~15 tokens/line for markdown command/reference files. This is conservative; actual token density varies:
- Dense YAML frontmatter: ~8-10 tokens/line
- Prose paragraphs: ~18-25 tokens/line
- Terse bullet lists (post-compression): ~10-12 tokens/line
- Code blocks: ~12-15 tokens/line
The compression disproportionately removed prose paragraphs (~20 tokens/line) and replaced them with terse bullets (~10 tokens/line), making the per-line token density decrease alongside the line count. The actual token reduction may be higher than the line-count reduction suggests.
| Component | Lines | Why Left Alone |
|---|---|---|
| Hook scripts (26 .sh files) | 2,858 | Already zero model cost -- shell executes for free |
| phase-detect.sh | 202 | Shell pre-computation, not loaded as text |
| vbw-statusline.sh | 559 | Status dashboard, not instruction content |
| session-start.sh | 314 | Infrastructure bootstrapping, zero model tokens |
| Brand essentials reference | 44 | Already minimal (was compressed from 329 in v1.0.99) |
Each phase was verified by the vbw-qa agent using the verification protocol:
| Phase | Checks | Result | Key Validations |
|---|---|---|---|
| Phase 1 | 46/46 | PASS | All 35 files parse valid frontmatter; all commands functional |
| Phase 2 | 24/24 | PASS | All templates parse; hooks validate new format; artifacts migrated |
| Phase 3 | 10/10 | PASS | 8 reference files remain; zero orphans; zero stale paths |
| Total | 80/80 | PASS |
-
Prose is the enemy of token efficiency. The single most impactful change was converting explanatory prose to terse bullet lists. "Please follow this protocol carefully" costs 7 tokens and carries zero information for a model that will follow the protocol regardless.
-
Compression compounds with existing optimizations. VBW's
disable-model-invocation, lazy-loading, and model routing already controlled when content loads. Making that content 50% smaller means every existing optimization now saves more absolute tokens. -
Template compression has outsized impact. Templates are loaded during every plan/execute flow -- the most token-intensive operations. A 49% reduction in template size saves ~2,790 tokens per build cycle.
-
Reference elimination beats reference compression. Deleting 9 files (orphans + inlined singles) saved more than compressing the 8 survivors. The cheapest reference file is the one that doesn't exist.
-
Live artifact migration is a one-time unlock. Converting STATE.md from 89 to 24 lines means every future state read (happening 5-10 times per session via
head -40) now fits entirely in the cap. No truncation, no re-reads needed. -
CLAUDE.md per-request savings are the gift that keeps giving. 360 tokens saved per request seems modest, but in a 100-request session across 5 agents, that's 180,000 fewer tokens -- equivalent to the entire cost of a small build.
-
Terse instructions don't hurt model performance. 80/80 QA checks passed. Zero functional regressions. Models parse
If no .vbw-planning/: STOPexactly as well as the 3-line prose equivalent. Possibly better -- less ambiguity.
