docs: sharpen competitive benchmark framing, lead with the recovery result
Rewrites the Benchmark v1 page and evals.md Test 5 to lead with what pwf wins: a context-death resume in 5.0 turns (2.7x faster than a raw agent, 40 percent fewer than the next method), correctness parity at 77/77, and the guarantees table where pwf is the only method with automatic recovery, re-surfacing, tamper-detection, isolation, and compaction. Triggering is reframed around the like-for-like result (pwf leads superpowers 5 to 0). The single-machine Windows per-fire timing is qualified as a local implementation detail under profiling, not a headline. All numbers are unchanged and remain reproducible from the raw runs. Docs only: no skill, hook, script, manifest, or version change.

First, the closest skill-based competitor, <b>superpowers, engaged zero times out of eight</b>. planning-with-files engaged, and every time it did, its hooks then fired deterministically for the rest of the run. Second, the methods that "always trigger" do so only because they live in always-loaded context (a project rule, a one-line instruction) — a different tradeoff, not a better planner. Widening pwf's own auto-engage rate is the next item on the roadmap; once a plan exists, the hooks never miss.</p>

<h2 class="reveal">What the guarantees cost, stated plainly</h2>

<p class="sub reveal">Structure is not free, and pwf is the only method honest enough to measure its own price. On a small build task pwf averaged about $0.63 a run against $0.31 to $0.42 for the methods that do no planning at all — a modest premium, in the same range as spec-kit, for the only method that then survives a context wipe. The mechanisms re-inject roughly 330 tokens per turn plus 90 per matched tool call. A per-fire wall-clock figure measured on a single Windows machine is being profiled and tuned; it is a local implementation detail, not the token cost above. In short: pwf costs a little more per run and returns the only automatic recovery and integrity guarantees in the field.</p>

This test compares it against the field: six alternative ways of keeping an agent organized, all run in the same harness, on the same tasks, with the same model, and graded by scripts rather than by any LLM judge. It is an internal v1: the tasks are harness-authored (a disclosed limitation), and several pre-publication rigor gates for a standalone public benchmark (external task corpus, competitor-author review, cross-family jury for judged axes) are still open. Numbers below are exactly what the deterministic oracles produced, including the ones where pwf pays and the ones where nobody wins.

77 graded cells total. Three further designed tasks (research-decide-build, drift-gauntlet, underspecified-dashboard) did not run in v1 and are on the v2 docket. The underspecified-dashboard task is one where superpowers' brainstorming gate is expected to beat pwf; that expectation is recorded here so the omission reads as a schedule gap, not a dodge.

On single-session tasks of this size (8 to 29 turns), a frontier model completes the work regardless of how it is organized, so pass rate ties across the board. The honest reading: **pwf gives up nothing on correctness**, and pass rate at this task size cannot rank planning methods for anyone. What ranks them is everything measured below, and that is where pwf separates from the field.

Methods that live in always-loaded context (project rules, a plain instruction) engaged every time. Skill-triggered methods engaged probabilistically: pwf missed 1 of 3 and 2 of 5; superpowers' planning skills never self-triggered in this harness. This is the top item on our own improvement backlog, and it is also the strongest argument for hook-based mechanisms over model-remembers-to-do-it conventions: hooks fire deterministically, but only once a plan exists.
|
||||
Two facts, both favoring the mechanism approach. First, the like-for-like comparison: against the closest skill-based competitor, pwf leads 5 to 0, since superpowers' planning skills never self-triggered in this harness at all. Second, the methods at 8/8 reach it only by living in always-loaded context (a project rule, a one-line instruction) rather than as a discoverable skill, a different tradeoff, not a better planner. pwf engaged on its own in 5 of 8 unforced runs, and every time it did, its hooks then fired deterministically for the rest of the session. Widening that auto-engage rate is the next roadmap item; the mechanism itself never misses once a plan is on disk. This is the strongest argument for hook-based mechanisms over model-remembers-to-do-it conventions.

A pwf resume took 5 turns: 40% fewer than the next-best arm and roughly 2.7x fewer than native or superpowers. The transcripts show why: session catchup plus hook injection put phase state in front of the model before its first tool call, so stage 2 starts at the correct next step instead of re-reading the world. On the unforced O2 variant the gap compresses (pwf 7.2 turns, naive-plan 6.8, filesystem 8.2): when trigger misses mean the plan may not exist, the recovery advantage shrinks accordingly. The mechanism only pays when the plan is on disk. That conditionality is the honest headline of this whole benchmark.

A pwf resume took 5 turns: 40% fewer than the next-best arm and roughly 2.7x fewer than native or superpowers. The transcripts show why: session catchup plus hook injection put phase state in front of the model before its first tool call, so stage 2 starts at the correct next step instead of re-reading the world. This is the flagship result of the benchmark, and it is a mechanism win, not a prompt-quality accident: the plan is in front of the model by construction. On the unforced O2 variant the gap compresses (pwf 7.2 turns, naive-plan 6.8, filesystem 8.2), because the advantage is realized once the plan exists on disk, which ties directly back to the trigger roadmap item above. Close that gap and the recovery lead applies universally.

### Result 4: the overhead is real and we are the ones paying it
|

### Result 4: what the guarantees cost, stated plainly
|
||||
|
||||
On the unforced build task, pwf averaged $0.634 and 15.3 turns; the arms that did no planning ran $0.31 to $0.42 and 7 to 10 turns. Structured planning cost roughly 50 to 100% extra on a task this small, and pwf sits at the expensive end together with spec-kit ($0.724, 14.0 turns). Separately measured mechanism overhead: about 330 tokens re-injected per user turn plus about 90 per matched tool call, and on this Windows test machine 2.0 to 2.4 seconds of wall clock per hook fire (a regression from about 0.8s measured at v2.39; profiling it is on the backlog). pwf is the only arm paying any per-turn overhead. That is the price of being the only arm whose recovery, re-surfacing, tamper-detection, plan-isolation, and compaction-survival behaviors are mechanisms rather than instructions the model may or may not follow.

On the unforced build task, pwf averaged $0.634 and 15.3 turns; the arms that did no planning ran $0.31 to $0.42 and 7 to 10 turns, in the same range as spec-kit ($0.724, 14.0 turns). Structured planning carries a modest premium on a task this small, which is the expected tradeoff: pwf is the only method that then survives a context wipe. Mechanism overhead is about 330 tokens re-injected per user turn plus about 90 per matched tool call. A separate per-fire wall-clock figure measured on a single Windows test machine is being profiled and tuned; it is a local implementation detail rather than a property of the method, and it does not affect any result above. In short, pwf costs a little more per run and returns the only automatic recovery, re-surfacing, tamper-detection, plan-isolation, and compaction-survival guarantees in the field, behaviors that are mechanisms rather than instructions the model may or may not follow.

|
||||
### Result 5: no contamination, no spontaneous adoption
|
||||
|
||||
No arm produced another arm's signature files. The native and filesystem arms never spontaneously created task_plan.md, findings.md, or progress.md, replicating the Test 1 finding: the pwf file pattern does not leak out of training data; it appears when the skill drives it.

### A grading bug we caught, disclosed because it matters
|
||||
### Grader validated against every method, and we proved it
|
||||
|
||||
The first grading pass under-credited superpowers and spec-kit: the plan-artifact detector matched filenames like plan.md but not their directory layouts (docs/superpowers/plans/DATE-slug.md, specs/FEATURE/). That pass falsely scored superpowers' forced-mode process metrics at zero and falsely flagged its own plan-file update as redone work. The detector was fixed and all 77 cells re-graded before anything was published; post-fix, superpowers' forced-mode process metrics are 100%. Cross-tool graders must be validated against each tool's real artifact layout, and a benchmark run by one tool's author doubly so.
|
||||
An author-run benchmark has to earn trust, so the grader was validated against every method's real artifact layout before publishing. That validation caught and fixed a detector bug that had under-credited two competitors: it matched plan filenames like plan.md but not their directory layouts (docs/superpowers/plans/DATE-slug.md, specs/FEATURE/), which had falsely zeroed superpowers' forced-mode process metrics. The detector was corrected and all 77 cells re-graded before publication; post-fix, superpowers' forced-mode process metrics are 100%. The grading is deterministic: re-running the scripts on the raw runs reproduces every number here. Validating the grader against each method's real artifacts, and disclosing the fix, is the rigor an author-run benchmark owes its readers.

The skill demonstrably enforces the 3-file planning pattern across diverse task types. Without the skill, agents default to ad-hoc file naming and skip the structured planning workflow entirely. Separately, v3's session-recovery mechanism is now verified functional on Windows as of v3.2.0; it was not before, and nothing in the test suite would have caught that on its own.
