Route a Missing Lint Binary to Its Documented Docker Invocation

[ptr727]

What

A command -v shellcheck (or markdownlint, cspell, actionlint, editorconfig-checker, shfmt,
PSScriptAnalyzer) miss reads as "not installed" unless the checker already knows these tools
are deliberately never installed natively on a fleet host, per GOVERNANCE.md "Running the
Linters Locally." Nothing sat at the point that check fails to say so, and CODESTYLE.md's own
Bash paragraph pointed only at the shell-codestyle Skill rather than at a runnable invocation.

Fix

• GOVERNANCE.md "Running the Linters Locally": states the general principle inline, that
  none of these tools is installed natively by decision, so their absence from command -v is
  expected rather than evidence the check is unavailable.
• CODESTYLE.md: the Bash paragraph now points at that section directly instead of only at
  the Skill, so a reader who consults the carried instruction file gets a runnable path without
  chasing a link.
• AGENTS.md: added a routing-table row ("Running a lint or format check locally, or a lint
  tool missing from command -v") so the deterministic, every-session-read entry point covers
  this too, rather than depending solely on the right Skill firing at the right moment.

Docs-only change; prose_lint.py, repo_gate.py, and the Docker markdownlint/cspell lint all
pass clean.

Fixes #763.

High-Level Assessment

The centralized routing approach is appropriate: GOVERNANCE.md remains the single source for executable lint guidance, while AGENTS.md and CODESTYLE.md link readers there at the relevant decision points. Duplicating Docker commands or recommending native installs would create drift or contradict fleet policy.

AGENTS.mdRoute lint tasks and PATH misses to governance guidance +1/-0

Route lint tasks and PATH misses to governance guidance

• Adds a routing-table entry for local lint or format checks and missing lint executables. This gives every session a deterministic path to the documented invocation.

AGENTS.md

CODESTYLE.mdLink shell clean-compile checks to Docker instructions +1/-1

Link shell clean-compile checks to Docker instructions

• Extends the shell guidance with a direct link to the canonical local-linter section. It explains that shellcheck and shfmt are intentionally absent from fleet-host PATHs.

CODESTYLE.md

GOVERNANCE.mdDocument expected absence of native lint binaries +1/-1

Document expected absence of native lint binaries

• Clarifies that supported lint tools are deliberately not installed natively on fleet hosts. A failed PATH lookup now explicitly directs readers to the known-working Docker invocation instead of treating the check as unavailable.

📝 Walkthrough

Walkthrough

The documentation now states that selected lint tools are intentionally absent from fleet hosts. It directs contributors to the documented Docker-based checks when command -v does not find a tool.

Changes

Local lint guidance

Layer / File(s)	Summary
Document lint tool routing AGENTS.md, CODESTYLE.md, GOVERNANCE.md	The guidance maps local lint and format checks to the governance instructions. Shell guidance and governance instructions explain that missing native tools are expected and that Docker-based checks must be used.

Estimated code review effort: 1 (Trivial) | ~3 minutes

Merge Risk: ⚪ Minimal · up to 28c9e

This documentation-only change clarifies how to run missing lint tools and routes readers to the authoritative guidance; no actionable merge-blocking risk remains after normal checks and review.

- Line 90: Align the AGENTS.md routing entry with the Governance heading by
ensuring “Running the Linters Locally” resolves to an exact level-two section
title in GOVERNANCE.md; preferably promote the existing “Running the Linters
Locally (Known-Working Invocations)” heading to level two while preserving its
content.

In `@CODESTYLE.md`:
- Line 54: Update the CODESTYLE.md guidance around the shell-codestyle skill and
GOVERNANCE.md link to remove the repeated native-tool availability policy,
including the command-PATH discussion; retain only the direct reference to
GOVERNANCE.md for running linters locally and preserve the remaining shell-style
rules.
