Commonmark Conformance is an agent skill from jolars/panache. Grow Panache's CommonMark spec conformance under Flavor::CommonMark by running every spec.txt example through the shared parser, comparing rendered HTML against the spec's expected HTML (byte-equality after list-item whitespace normalization), and triaging failures into renderer / parser-shape / flavor-leak / dialect-divergence / missing-feature buckets. Use when asked to advance the CommonMark pass rate, grow the allowlist, or unblock a CommonMark regression.
Its SKILL.md is about 1.1k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Databases, covering Database schema design and Linting and formatting. It works with Pandoc. The repository describes itself as: Language server, formatter, and linter for Markdown, Quarto, and R Markdown. The licence is MIT.
Read from SKILL.md and the folder at commit e28d49b. It shows what the files ask for, not the result of running them.
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

Shell commands in SKILL.md call:

Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Commonmark Conformance loads about 1.1k tokens when it runs. Until then it costs about 123 tokens; SKILL.md has 342 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

.claude/skills/commonmark-conformance/SKILL.md (or your agent's skills folder).Panache's parser is shared across all flavors (Pandoc, Quarto,
RMarkdown, GFM, CommonMark, MultiMarkdown). Each flavor selects a
baseline set of extensions through Extensions::for_flavor(). Under
Flavor::CommonMark, almost every Pandoc-specific extension is
disabled, leaving only constructs that appear in the
CommonMark spec. Conformance is
tracked by running every spec.txt example through the parser and
comparing rendered HTML against the spec's expected HTML.
Follow the CommonMark conformance and parser invariants in the repository's
root AGENTS.md; the workflow below supplies the task-specific procedure.
| Path | Purpose |
|---|---|
crates/panache-parser/tests/fixtures/commonmark-spec/spec.txt | Vendored CommonMark spec. |
crates/panache-parser/tests/commonmark.rs | Test runner (commonmark_allowlist, commonmark_full_report). |
crates/panache-parser/tests/commonmark/spec_parser.rs | Parses spec.txt into example records. |
crates/panache-parser/tests/commonmark/html_renderer.rs | Test-only CST → HTML renderer (not a public API). |
crates/panache-parser/tests/commonmark/allowlist.txt | Example numbers currently passing. CI fails on regression. |
crates/panache-parser/tests/commonmark/blocked.txt | Examples we deliberately do not target yet, with reasons. |
The renderer mirrors the byte-equality comparison commonmark-hs uses:
the output is normalized via <li>\n → <li> and \n</li> →
</li> before comparison.
Running commonmark_full_report writes two generated, git-tracked
artifacts beside the harness (no longer under docs/):
crates/panache-parser/tests/commonmark/report.txt — per-section
counts plus the full list of passing example numbers. Use this to
grow the allowlist after fixing parser/renderer bugs.crates/panache-parser/tests/commonmark/report.json — the same
data as a structured sidecar (spec_version, total_examples,
passing, failing, blocked, per-section sections,
passing_numbers).Both are derived — regenerate them, don't hand-edit.
# Regression guard: every allowlisted example must still pass.
cargo test -p panache-parser --test commonmark commonmark_allowlist
# Full report: regenerates report.txt + report.json.
cargo test -p panache-parser --test commonmark commonmark_full_report \
-- --ignored --nocaptureTo grow the allowlist: fix a parser or renderer bug (with a focused
regression test reproducing it), run commonmark_full_report, verify
the newly-passing numbers appear in report.txt, then add them to
allowlist.txt grouped under their section header. Run
commonmark_allowlist to confirm. If an example is intentionally not
targeted, add it to blocked.txt with a reason.
The CommonMark spec defines conformance as markdown-input →
HTML-output byte-equality. Panache's primary output is formatted
markdown, not HTML, so the harness needs a renderer to bridge the
gap. The renderer in tests/commonmark/html_renderer.rs is test
code only — it is not part of the public crate surface, and it
covers only the constructs spec.txt exercises. If a public
--to html mode is wanted later, the renderer can graduate from
test-only to a real module; until then it intentionally stays narrow.

Grow Panache's CommonMark spec conformance under Flavor::CommonMark by running every spec.txt example through the shared parser, comparing rendered HTML against the spec's expected HTML…. Commonmark Conformance is an agent skill from jolars/panache.txt example through the shared parser, comparing rendered HTML against the spec's expected HTML (byte-equality after list-item whitespace normalization), and triaging failures into renderer / parser-shape / flavor-leak / dialect-divergence / missing-feature buckets.
Commonmark Conformance fits situations like: asked to advance the CommonMark pass rate; grow the allowlist; unblock a CommonMark regression.
Run `npx skills add jolars/panache --skill commonmark-conformance -a claude-code`. Or copy the skill folder (.agents/skills/commonmark-conformance in jolars/panache) into .claude/skills/commonmark-conformance in your project. Claude Code loads it when a task matches its description.
Run `npx skills add jolars/panache --skill commonmark-conformance -a codex`. Or copy the skill folder (.agents/skills/commonmark-conformance in jolars/panache) into .agents/skills/commonmark-conformance in your project. Codex loads it when a task matches its description.
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add jolars/panache --skill commonmark-conformance -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/commonmark-conformance, .gemini/skills/commonmark-conformance, .github/skills/commonmark-conformance and .opencode/skills/commonmark-conformance in your project.
Going by SKILL.md and its folder, Commonmark Conformance needs the command-line tools its instructions call (cargo).
SKILL.md names 1 domain. As links in the text: spec.commonmark.org. This is read from the text; nothing was executed.
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
Commonmark Conformance is published under the MIT licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
About 1.1k tokens (SKILL.md is roughly 4.3k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
