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.

* docs: add a Commands reference to the README
The commands were only mentioned scattered through prose, and two install
blurbs had gone stale (OpenCode omitted /ponytail-debt, Gemini omitted audit
and debt). Add one canonical Commands table (all five commands + what each
does + which hosts support them) and point the install blurbs at it so they
stop drifting as commands are added.

* docs: add pi to the portability table, de-stale the Gemini row
pi was a supported integration (pi-extension, README install, registers all
the commands) but had no row in the Supported Adapters table. The Gemini row
also enumerated an outdated command list; point it at commands/*.toml
generically so it stops drifting.

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.

* 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.

Release-prep bump across the Claude Code, Codex, and Gemini manifests.
Cutting v4.3.0 also fixes#33: gemini extensions install pulls the latest
GitHub release, and gemini-extension.json was added after v4.2.0, so it
was missing from the release tarball. Shipping it in a release fixes the
plain install command.

ponytail-activate.js and ponytail-runtime.js hardcoded ~/.claude for the
flag file and settings lookup, ignoring CLAUDE_CONFIG_DIR. Add a shared
getClaudeDir() to ponytail-config.js and use it in both. Regression test
added to hooks.test.js.

* 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).

Copilot CLI already reads AGENTS.md and .github/copilot-instructions.md
(both shipped), plus a global ~/.copilot/copilot-instructions.md. Add an
agent-portability row and a README note. Instruction-tier only: no
/ponytail levels or hooks.

* feat: add Gemini CLI support
Add a thin Gemini CLI extension adapter (closes#22). The manifest points
contextFileName at the existing AGENTS.md for always-on rules and reuses the
repo's commands/*.toml (/ponytail, /ponytail-review) and skills/, which Gemini
CLI auto-discovers — no rule text is duplicated.

* 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.

On Windows the lifecycle hooks run via PowerShell, which does not expand
cmd.exe-style %CLAUDE_PLUGIN_ROOT%. The path was passed literally, so the hook
launcher could not find the script and both SessionStart and UserPromptSubmit
failed with exit code 1 (issue #19). Switch the two commandWindows entries to
$env:CLAUDE_PLUGIN_ROOT, keeping the working node + .js invocation.
Add a regression test that rejects cmd.exe %VAR% syntax in commandWindows and
asserts every hook command points at a script that actually ships in hooks/.

* Add ponytail-audit skill
Whole-codebase audit for over-engineering. Scans a repository and produces a
ranked report of things to delete, simplify, or replace with stdlib/native
equivalents.
* Drop counting-by-number heuristics: remove Phase 5 (structural audit) and TODO-age heuristic per review
* feat: slim ponytail-audit and add cross-platform parity
Rewrite the ponytail-audit skill to ponytail-review's lean shape (35 lines,
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

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.
Cover the Kiro steering file in the equality check (the stripper is now shared, renamed to stripFrontmatter), and align its body with AGENTS.md: the 'Not lazy about' and 'Non-trivial logic' sentences were split into two paragraphs where the canonical body and the other four copies keep them as one. The improved check caught this on the freshly merged #6.
Also add a small invariant canary: four load-bearing rule phrases must appear verbatim in both SKILL.md (the runtime source of truth) and AGENTS.md, catching a rule that lands in one but not the other even though the two files are intentionally different lengths.
Verified: passes on main, exits 1 when a copy diverges or an invariant goes missing.

Adds the Codex adapter: marketplace.json, .codex-plugin/plugin.json,
declarative hooks.json with Windows command variants, and a shared
hooks/ponytail-runtime.js that switches state path and output format
between Claude and Codex (gated on PLUGIN_DATA, so the Claude path is
unchanged). Bumps plugin version to 4.1.0 and ships tests/hooks.test.js.
README adapters block resolved to keep the Codex @ponytail invocation note
together with Kiro (#6) and the drift-check Development section (#3).

Six no-skill control arms re-run through the same harness so all three
arms share one model. README Numbers section and chart now cite the
complete dataset: -47% tokens, 3x faster, 490 vs 3,629 LOC, extension
96 vs 1,115 lines, probes green everywhere. Em dashes removed.

Hardening per the A-F benchmark brief: non-trivial logic leaves one
runnable check; ponytail: comments on ceiling-bearing shortcuts name
the ceiling and upgrade path; prefer the edge-case-correct stdlib
option at equal size. Applied to SKILL.md, all cross-agent rule
copies, the hook fallback, and a guard line in ponytail-review.

Skill preaching minimalism was 2x caveman length. Smaller file cuts
per-read and per-session-injection cost. Benchmark: beats caveman on
all areas now — 135.7k vs 138.4k tokens, 127s vs 136s, 47 vs 117 loc.
v1 lost to caveman on tokens/time despite minimal code: it wrote
essays defending each simplification. v2 caps explanation at three
lines and ships the lazy version instead of stalling on necessity
questions. Benchmark: 136.6k tok vs caveman 138.4k, code 47 vs 117
lines across 5 tasks.
