The LOC tier scores the open feature tasks (vibe-*, tmpl-fe-*, open-*) on
git diff alone -- score_vibe only checks "it compiles", score_fixture only
checks "a new file exists". So an arm can win the LOC metric by shipping a
stub: fewer lines because it does less, not because it is less bloated.
That is the most credible attack left on the headline number raised in #126.
complete.py is a second LLM judge (same auditable footing as judge.py: fixed
model, temperature 0, published rubric) that rates how FULLY each submission
implements its task, 0..3. Read alongside the LOC table, a low-LOC arm whose
completeness also drops is caught, not rewarded.
- judge_call gains a `system=` param so the HTTP/key/source plumbing is reused
instead of duplicated (one rubric is the only delta between the two passes).
- --selftest: the judge must rank a complete reference strictly above a stub.
- --selftest-offline: validates the gate logic with no API call / no key.
- README documents the pass and updates the can/cannot-show limitations.
Fixes#126

The ponytail/caveman arms hardcoded one machine's Windows plugin-cache
paths (C:\Users\Dietr\...), so only baseline/yagni/yagni-oneliner were
reproducible off the maintainer's box — undercutting the "fully
reproducible" claim the rebuilt benchmark (#126) was meant to establish.
Resolve per-arm at use-site: env override (PONYTAIL_PLUGIN_DIR /
CAVEMAN_PLUGIN_DIR) -> latest version dir under ~/.claude/plugins/cache
-> clear sys.exit. No pinned version/hash. Selftest extended to cover
env-override and missing-install paths.
Fixes#169

The hero showed only ~54% (the mean); the rigorous agentic run also reaches 94%
on the over-build tasks (the date picker), so the headline now reads
"~54% (up to 94%)". The sub-line is reworded so 80-94% reads as the per-task
ceiling against a fair baseline, not the old single-shot figure, which would
otherwise contradict the hero.

Grouped bars of LOC, tokens, cost and time as a % of the no-skill baseline
(lower is leaner/cheaper/faster), plus a separate safety strip (baseline,
caveman and ponytail 100%; yagni-oneliner 95%). System-gray palette so it reads
on both GitHub themes. The chart commits landed after #158 had already
squash-merged, so this brings the chart onto main.

Rebuild the benchmark to the standard #126 asked for: real headless Claude Code
sessions (not a bare model) editing a real public repo
(tiangolo/full-stack-fastapi-template @ cd83fc1, MIT), fair arms (baseline,
caveman, ponytail, and the "YAGNI + one-liners" prompt), n=4, Haiku 4.5. LOC is
the git diff; the safety tasks execute the produced code against adversarial
input.
Results: ponytail -54% LOC mean (up to -94% on over-build features like the
date/color picker), -22% tokens, -20% cost, -27% time, and never more than
baseline; 100% safe vs the one-liner prompt's 95% (it dropped a path-traversal
guard once). caveman writes less code but spends more tokens.
Also fixes a baseline-contamination bug (the ponytail plugin's SessionStart hook
fired on every arm; now isolated with --setting-sources project,local + per-arm
--plugin-dir) and a Windows subprocess-timeout hang.
Lead both READMEs with the agentic numbers; demote the single-shot 80-94% to a
labelled "isolated generation" note; supersede the contaminated 2026-06-17
writeup. Dead react-app fixture left untracked.

* docs: correct cost claim to 42-75% from 30-rep re-verification
Re-ran the cost benchmark at 30 reps per cell on Claude (Haiku/Sonnet/Opus):
ponytail is 42-75% cheaper than no-skill, not the previously published 47-77%.
The direction holds, both ends came in a few points lower. Updates the README
headline and body, the benchmark chart subtitle, and the benchmarks/README cost
table, and adds a dated results doc with full method.
Also adds the OpenAI (gpt-4.1-mini/gpt-5.4-mini/gpt-5.5) and Gemini configs. On
OpenAI reasoning models ponytail costs more, not less, so the claim stays
Claude-scoped. Gemini run pending a fresh-quota day.

The cost/code/latency numbers vary by model and on some (terse reasoning

The ladder is a deliberation step: on reasoning models the agent spends
thinking tokens working through the rungs before it saves any output, which
together with the always-on ruleset can outweigh the shorter code. Makes the
GPT-5.5 cost increase legible rather than just stating it.

* docs: state the single-shot limitation honestly
The benchmark is single-shot (one prompt, one completion); it does not measure
a real multi-turn agent session, where the ruleset re-injects and the ladder
deliberates every turn. Adds that caveat to the README, and corrects the
benchmarks/README note that claimed caching widens the gap "in ponytail's
favor" (unverified, and a measured agentic A/B in #121 found the opposite can
happen). Per-session cost can land either way.

* fix(examples): replace hand-written examples with real benchmark output
The examples/ before/after blocks were authored by hand, not produced by a
model. Issue #127 correctly noted that nobody hand-rolls quicksort for "sort
this array" - every model just calls .sort(). Regenerate all examples verbatim
from a real benchmark run (Claude Haiku 4.5, no-skill arm vs ponytail arm,
benchmarks/output.json) so the before/after is reproducible, not authored:
email 75->3, debounce 116->10, csv 20->3, countdown 267->9, rate-limit 128->10 LOC
- Delete sorting.md (pure strawman) plus the other hand-written caricatures
(api-endpoint, caching, date-picker)
- Add benchmarks/generate-examples.mjs to regenerate examples from any run
- examples/README.md indexes the set and documents how to reproduce
Closes#127

* fix(benchmarks): correctness gate scores unfenced code; fix debounce task
The `correct` gate under-reported correctness for terse models, the likely
source of "Ponytail degrades models" reports (issue #65):
- extractBlocks() only matched fenced code blocks, so bare/unfenced code
scored an automatic fail even when correct. Now falls back to the whole
response as one block (and tolerates CRLF). Debounce detection also accepts
unfenced arrow functions.
- The debounce task asked to "add debounce to a search input" but the check
expected a reusable debounce(fn, delay) util, failing correct inline answers.
Task reworded to the deliverable the check verifies.
Adds correctness.test.js (regression guard) and a GPT-mini repro config plus
results writeup: on a clean n=20 run, the reported gpt-4.1-mini drop (10/15)
does not reproduce (100/100). The LOC win (~halved) holds.
README repro fixed: promptfoo needs --env-file ../.env (reads cwd, not root).

* test(benchmarks): add robustness audit — ponytail vs baseline on edge cases
Answers the real question behind #65: does ponytail's push for the shortest
solution make weak models produce wrong code on edge cases?
robustness-audit.js: 16 self-verifying tasks (12 algorithmic edge-case traps +
4 validators). Each check ships a known-good and known-lazy-wrong reference that
must pass/fail before any model output is scored (--selftest, 16/16).
Findings (gpt-4.1-mini + gpt-5.4-mini, baseline vs ponytail): parity on every
edge-case trap on both models. The one measured soft spot is gpt-5.4-mini email
(~4-5%, reaches for parseaddr). A sharpened SKILL.md validation rule had no
reliable effect in an n=100 A/B (96% vs 95%), so it was not shipped — the
tendency is model-level, not skill-level. Full writeup in results/.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
* test(benchmarks): email slip is provider-specific — 100% on Claude
High-n cross-provider follow-up to the robustness audit. The one ponytail
soft spot (email validation via parseaddr) splits by provider, not model size:
- Claude (haiku/sonnet/opus): 100% under ponytail, n=40 each — and ponytail
beats baseline (unconstrained Sonnet over-engineers into an always-truthy
dict, 0/40; ponytail writes a clean validator).
- OpenAI (gpt-4.1-mini..gpt-5.5): slips at every size under ponytail
(~79-98%), baseline ~100%. The parseaddr reflex lives in OpenAI training.
Not fixable by skill text: 8 distinct SKILL.md edits (incl. an n=100 A/B,
96% vs 95%) all scored <= current, several worse, all bloated LOC. Nothing
shipped. SKILL.md unchanged.
Conclusion: on ponytail's target platform (Claude) email is 100%; the GPT
slip is a documented cross-provider transfer quirk. Adds model-email.js /
claude-email.js to reproduce the tables. Writeup updated.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
* docs(benchmarks): correct misleading Sonnet baseline 0 percent
The Sonnet baseline 0/40 on email is a return-type artifact, not a logic
failure: unconstrained Sonnet returns a dict {is_valid, message} instead of a
bool, so the bool-contract gate scores every case as accepted. Read dict-aware
via is_valid, its logic is ~75% correct (9/12). Reframed honestly so we are not
presenting 0 vs 100 as a clean win; ponytail still wins (clean 100% bool) but
the point is over-engineered return type, not total failure.

Claude Code runs hooks via a non-interactive /bin/sh. On setups where node
isn't on that shell's PATH (Nix/nix-darwin, nvm, fnm), every prompt errored
with "/bin/sh: node: command not found". Guard each hook command so it runs
node only when present and exits 0 otherwise, no more per-prompt noise. The
slash-command skills are unaffected; only the always-on activation needs node.
Document the requirement in the README install section.

A `git add -A` during the v4.4.0 bump accidentally tracked the announcement

gitignore the pattern; they stay on disk for posting but out of the repo.
The header showed logo.png (black on transparent), which nearly vanishes in
GitHub's dark theme. Wrap it in a <picture> so dark-theme viewers get the
contoured logo-dark.png and light-theme viewers keep the original.
A dark-bg-ready variant of the mark: white face fill plus a die-cut white
contour so it reads on dark backgrounds, where logo.png (black on transparent)
and the social-preview face do not. Ships as SVG (scalable, white + black
layers) and a 1085x1241 PNG.

Closes the last gap from the field review: deferral creep. /ponytail-debt
greps the repo for `ponytail:` comment markers and prints a ledger
(file:line, what was simplified, ceiling, upgrade trigger), flagging any
marker with no trigger as the rot risk. One-shot, reports only.
Full parity like ponytail-audit: skill + commands/.toml + .opencode/.md + pi
registerCommand (+ test) + agent-portability + README.
Verified: tests 32/32 (pi command list updated), rule check green, the scan
finds the repo's real markers, and a live end-to-end run produced a correct
ledger (2 markers, 1 no-trigger, prose/examples excluded).

* feat: refine ruleset from a full-project field review
A reviewer ran ponytail across a 9-phase rewrite (protocol, PC app, simulator,
RPi daemon, ESP32 firmware) and flagged three gaps. All three land in SKILL.md
and propagate to AGENTS.md + the rule copies:
- Promote the one-runnable-check rule to a headline ("Lazy code without its
check is unfinished"), enforced as a check-rule-copies invariant.
- Hardware carve-out in "When NOT to be lazy": a real device is never the spec
ideal (clock drift, sensor offset), leave the calibration knob.
- Clarify the Output rule: explanation the user explicitly asked for is not
debt, only unrequested prose is.
Fallback instructions kept in sync. Rule-copy check + tests green.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
* test: add a behavior gate proving the refinements actually fire
The refinements were verified as injected text, but injected != behavioral.
This adds a behavior eval that probes each refined rule on a task that should
trigger it:
- hardware -> does the output leave a calibration knob?
- explanation -> when a write-up is explicitly requested, is it given in full?
- onecheck -> is a runnable check left behind?
benchmarks/behavior.yaml runs the probes (baseline vs ponytail arm); the
grader benchmarks/behavior.js is proven by tests/behavior.test.js (8 cases,
RED/GREEN, no API key, runs in CI). Live-confirmed: the model under the
current ruleset passes all three gates, graded by the same grader.

* feat(benchmarks): add correctness assertion - proves less code is not broken code
The existing benchmark measures lines-of-code (loc.js) but never checks
whether the generated code actually works. This adds a functional
correctness gate (correctness.js) that extracts code from fenced blocks
and runs per-task checks:
- email validator: spawns Python, asserts accept/reject on 5 inputs
- debounce: spawns Node, asserts delayed execution + reset on re-call
- csv sum: spawns Python with a test CSV, asserts correct total (351)
- countdown (React): structural check (useState + useEffect + decrement)
- rate limiter (FastAPI): structural check (limit logic + framework usage)
12 unit tests (node:test) cover good/bad outputs for every task plus the
unknown-task edge case. Existing tests and rule-copy checks unaffected.
* fix: address review feedback
- csv check: use regex lookaround instead of substring match to prevent
false positives (e.g. 13510 containing '351')
- ratelimit: fix operator precedence in block finder by adding parens
around the || inside the !b.lang guard
- README: note that React/FastAPI checks are structural only, add
prerequisites section (Python 3, pandas, Node.js 18+)
- test: add regression test for csv substring false positive
Both read AGENTS.md, which the repo already ships, so ponytail works
from the repo root with no extra setup. Add agent-portability rows and a
README note. Instruction-tier (no /ponytail levels or hooks).

* feat: add Gemini CLI support
Add a thin Gemini CLI extension adapter (closes#22). The manifest points

* test: read manifest inside cases for a clean RED
The manifest was parsed at module scope, so reverting the adapter crashed the
whole test file at load (ENOENT) and collapsed all four cases into one
unreadable failure. Read it inside each case via a helper that asserts existence
first, so a missing or malformed manifest surfaces as clear per-case assertion
failures instead of a stack trace.

was 111): same five tags, repo-wide scope, ranked output. Drop the
prescriptive phase walkthrough, sampling rules, report template, and the
license frontmatter that no other skill carries.
Add the adapters the skill was missing so it ships on every supported
platform the way ponytail-review does:
- commands/ponytail-audit.toml
- .opencode/command/ponytail-audit.md
- pi-extension registerCommand (+ test)
- agent-portability and README entries

Use auto-update or marketplace refresh + /reload-plugins (not reinstall), and
note that an unrecognized /plugin means Claude Code itself needs updating.

Swap em dashes for commas/colons/periods in the README, skills, AGENTS.md and
its five rule copies, examples, command files, and benchmark README. Rule
copies stay in sync (same edit applied to all) and the invariant guard passes.
Left untouched on purpose: the vendored caveman SKILL.md (verbatim third-party
text), the dated benchmark writeups in results/ (historical records), and
.js code comments.

The ponytail API example returned the raw ORM model, which exposes every
column. Restore a response_model whitelist (the trust boundary) while still
cutting the repository/service/exception ceremony. Matches the skill's own
'never cut security' rule.

Commit a promptfoo harness (config + arm prompts + LOC metric + vendored
caveman SKILL) so anyone can re-run the comparison: no-skill vs caveman vs
ponytail, across Haiku / Sonnet / Opus, 10 runs per cell, median reported.
Replace the old unreproducible 6-task chart with assets/benchmark-3model.svg
from this run, and reframe the README to the reproducible numbers: ponytail
writes 80-94% less code, costs 47-77% less, and runs 3-6x faster than a
no-skill agent on every model. benchmarks/README.md carries the median tables
and the reproduce command. Drops nothing that is not measured.

hooks/hooks.json used ${PLUGIN_ROOT}, which Claude Code never defines, so the literal resolved against the hook process cwd and SessionStart/UserPromptSubmit failed with 'Cannot find module'. Switch to ${CLAUDE_PLUGIN_ROOT} (and %CLAUDE_PLUGIN_ROOT% for the Codex commandWindows variant); Codex aliases CLAUDE_PLUGIN_ROOT so both hosts resolve. Drop the duplicate inline hooks block from .claude-plugin/plugin.json so hooks load from a single canonical source.
filterSkillBodyForMode only filters lines whose label is a real mode (lite/full/ultra). Rule bullets like 'No unrequested abstractions:' and the 'ponytail:' comment convention were being stripped from injected instructions in every mode. Adds regression test.
