docs(pc-skills): trim generic pre-commit boilerplate (finding 38)

Browse Source 
Collapse the per-language hook tables in pc-author's hooks-by-language.md
into one shared-repo table plus an "other repos" table, dropping the
repeated repo/rev/rationale text that just restated what each hook does.
128 -> 92 lines. Kept both "Unverified — not in research corpus" flags
and the rev-freshness caveat.

Remove the generic SSH/proxy CI failure sections, the shellcheck SC-code
listing, and compress the generic validate-config schema-error bullets
in pc-run's failure-patterns.md, all of which just restated
pre-commit.com's own docs. 133 -> 109 lines. Kept the rtk-prefixed
re-stage/recommit fix (ADR-0023), the "do NOT reach for
`pre-commit install -f`" warning, and both gitleaks/shellcheck
not-sourced-from-corpus notes.

Combined cut: 60 lines. Flat mirrors regenerated via
scripts/sync-plugin-content.sh and verified byte-identical
(--check exits 0); no plugin.json drift.

## Universal (recommend for every repo)

| Hook ID | Repo | Rev | Rationale |
|---------|------|-----|-----------|
| `end-of-file-fixer` | `https://github.com/pre-commit/pre-commit-hooks` | `v6.0.0` | Ensures files end with a newline — prevents spurious diffs |
| `trailing-whitespace` | `https://github.com/pre-commit/pre-commit-hooks` | `v6.0.0` | Strips trailing whitespace — prevents invisible diff noise |
| `check-merge-conflict` | `https://github.com/pre-commit/pre-commit-hooks` | `v6.0.0` | Catches unresolved merge markers before commit |
| `detect-private-key` | `https://github.com/pre-commit/pre-commit-hooks` | `v6.0.0` | Blocks PEM private key material |
| `check-added-large-files` | `https://github.com/pre-commit/pre-commit-hooks` | `v6.0.0` | Blocks accidentally committing large binary files |
| `check-case-conflict` | `https://github.com/pre-commit/pre-commit-hooks` | `v6.0.0` | Catches filenames that would collide on case-insensitive filesystems |
| `mixed-line-ending` | `https://github.com/pre-commit/pre-commit-hooks` | `v6.0.0` | Normalizes line endings |
| `no-commit-to-branch` | `https://github.com/pre-commit/pre-commit-hooks` | `v6.0.0` | Blocks direct commits to protected branches — defaults to blocking `main`+`master` with no args; add `args: [--branch, <name>]` only to protect additional branch names |

## Shell (`.sh`)
Full repo URL: `https://github.com/pre-commit/pre-commit-hooks`. For Python formatting, check if `black`, `ruff`, or `isort` is already configured in `pyproject.toml` before recommending them.
| Hook ID | Repo | Rev | Rationale |
|---------|------|-----|-----------|
| `shellcheck` | `https://github.com/jumanjihouse/pre-commit-hooks` | `3.0.0` | **Unverified — not in research corpus, verify upstream before use.** Static analysis for shell scripts; catches common errors |
## Other repos
Recommended args: `args: [--severity=warning]`
## Python (`.py`)
| Hook ID | Repo | Rev | Rationale |
|---------|------|-----|-----------|
| `check-ast` | `https://github.com/pre-commit/pre-commit-hooks` | `v6.0.0` | Validates Python files parse as valid AST |
| `check-builtin-literals` | `https://github.com/pre-commit/pre-commit-hooks` | `v6.0.0` | Enforces literal syntax for `dict()`, `list()` |
For formatting: check if `black`, `ruff`, or `isort` is already configured in `pyproject.toml` before recommending them.
## JSON (`.json`)
| Hook ID | Repo | Rev | Rationale |
|---------|------|-----|-----------|
| `check-json` | `https://github.com/pre-commit/pre-commit-hooks` | `v6.0.0` | Validates JSON parses correctly |
| `pretty-format-json` | `https://github.com/pre-commit/pre-commit-hooks` | `v6.0.0` | Auto-formats JSON (fixer — warns user to re-stage after commit) |
## YAML (`.yaml`, `.yml`)
| Hook ID | Repo | Rev | Rationale |
|---------|------|-----|-----------|
| `check-yaml` | `https://github.com/pre-commit/pre-commit-hooks` | `v6.0.0` | Validates YAML parses correctly |
For Kubernetes/Helm YAML with custom tags, add `args: ['--unsafe']` and `exclude: ^helm/templates/`.
## TOML (`.toml`)
| Hook ID | Repo | Rev | Rationale |
|---------|------|-----|-----------|
| `check-toml` | `https://github.com/pre-commit/pre-commit-hooks` | `v6.0.0` | Validates TOML parses correctly |
## Secrets / security
| Hook ID | Repo | Rev | Rationale |
|---------|------|-----|-----------|
| `gitleaks` | `https://github.com/gitleaks/gitleaks` | `v8.30.1` | **Unverified — not in research corpus, verify upstream before use.** Scans for secrets and high-entropy strings |
## Commit message
| Hook ID | Repo | Rev | Stage | Rationale |
|---------|------|-----|-------|-----------|
| `conventional-pre-commit` | `https://github.com/compilerla/conventional-pre-commit` | `v2.4.0` | `commit-msg` | Enforces Conventional Commits format |
When adding commit-msg hooks, also add `default_install_hook_types: [pre-commit, commit-msg]` to the top-level config if not already present.

## Rev pin freshness
The revs above were last verified current at time of writing (matched against the plugin's own research corpus in `docs/research/docs/pre-commit/`; rows marked "Unverified" have no such backing and must be checked against upstream before use). Since the "Rev staleness" check in `references/modify-config.md` treats this table as ground truth, a pin that goes stale here produces false-positive staleness warnings for users who already have a newer, correct rev. Re-verify these pins periodically (e.g. against each repo's latest release tag). When in doubt, treat `pre-commit autoupdate`'s own output as the authoritative staleness signal, not a mismatch against this table.
