Forward trace: requirement → decision → commit → gate → verification → CI on that sha → release → closure. The distinction the skill exists for is that each link is either checked or named as unchecked; a trace where every link is asserted is a narrative, and narratives are what audits exist to defeat. `trace.sh` does the mechanical part — commit, files, test files touched, release containing it, referenced issues as URLs — and then always prints the four things git cannot prove. The GREEN run's own accounting: "the tool did the mechanical 15%. Its real contribution is the 'Cannot verify from here' block, which is a checklist, not an output." Kept, because it is true. The RED run established the shape by tracing a commit by hand in sixteen steps. Its decisive moves were reading issue COMMENTS — where the decisions actually live — and running a probe that falsified a claim. Both are now steps. The GREEN run then used step 5 against a gate I shipped this morning, and broke it. It also found four things wrong with what I had written: - The slug sed used `[^/]+?` expecting a lazy quantifier. POSIX ERE has none, so `.git` was swallowed and every emitted evidence URL carried the suffix. It happened to work against Gitea and would 404 on GitHub — a bad failure for the one tool whose pitch is that an unchecked link must not look checked. - "Prints every issue it references" was overclaimed: it greps the commit body, so it structurally cannot find the issue that cites the COMMIT. That is the commoner break — the issue filed afterwards that falsifies the outcome — and it is now step 6 with the two searches that find it. - Step 3 told you to check which job passed, and the estate's own `workflow_run_status` returns no jobs. A step whose tooling dead-ends is where a trace becomes "the run was green"; the REST fallback is now written out. - The output format did not survive contact. It grew four slots, each forced by a real trace: two requirements differing in kind (a defect report and a standing bar), the gate as an artifact separate from the test, the RED/GREEN baseline against the parent, and the commit's factual claims checked. Without the last one, "commit → verified" means only "this sha exists". Also: `git describe --contains` reads local tags, so the tool now says so on every hit rather than only when it finds nothing.

Engineering Skills Index
This index lists all available engineering skills. Load the full SKILL.md on demand.
The table is generated from each skill's frontmatter (summary, use_when,
surfaces) by task index, and task check fails if it is out of date. Edit

Wiring into tools
This repo is the canonical home, and it is delivered two different ways.
Claude Code — install the plugin
This repo hosts a marketplace containing exactly one plugin: itself. The plugin
carries the skills plus the secret-guard and pre-task-ritual hooks and
the brain/gitea/infra MCP servers — none of which a symlink can deliver.
/plugin marketplace add https://git.d-ma.be/mathias/skills.git
/plugin install skills@mathias
Skills are namespaced: tdd becomes skills:tdd. Updates arrive when
.claude-plugin/plugin.json's version moves, which CI does on every release.
Remove any leftover ~/.claude/skills/<name> symlinks from the pre-plugin era —
plugin skills do not override same-named user skills, so leftovers make
everything load twice.
Crush, Pi, OpenCode — run install.sh
These have no plugin system, so they get symlinks — but through one managed directory, never one link per skill per harness:
~/.agents/skills/ (real directory; Pi reads it directly)
~/.agents/skills/tdd -> $SKILLS_CHECKOUT_DIR/skills/tdd
~/.agents/skills/xlsx -> $SKILLS_EXTRA_SOURCES entry
~/.config/crush/skills -> ~/.agents/skills
~/.config/opencode/skills -> ~/.agents/skills
Total links are N + one per harness. SKILLS_EXTRA_SOURCES (colon-separated
directories) lets a second library — Anthropic's official set, for instance —
live alongside this one instead of being displaced by it; name collisions are
logged rather than silently resolved, and the checkout wins (#27).
curl -fsSL https://git.d-ma.be/mathias/skills/raw/branch/main/install.sh | bash
SKILLS_CHECKOUT_DIR defaults to ~/.local/share/skills and must stay
outside ~/dev. On this fleet ~/dev is an iCloud folder shared by both
Macs and spans two path roots (/Users/mathias vs /home/mathias on koala);
a checkout there means a git working tree with two concurrent writers, and any
absolute link stored there is broken on one side by construction. See #23.
Check a host
task doctor (or bin/doctor) reports dangling links, links into a source
nobody configured, skills in the checkout with no link, stray entries, leftover
Claude symlinks, and a Claude Code plugin sitting on an older generation than
the host already has. It also runs automatically at session start via the
plugin, so drift announces itself instead of waiting to be found.
