Lint

Runs on: local-exec - Check 6 runs a read-only script. Every other check is reading, so on a surface without script access run Checks 1 to 5 and mark Check 6 as not run.

Read-only audit of the wiki layer. Returns a structured report. Never modifies files.

This skill must:

• Run end to end on a fresh install (clean output, no false positives).
• Run on a populated install and surface real findings with file:line references.
• Render in under 5 seconds for installs with under 1000 wiki files.
• Never write to any file.

Pre-flight

If core/identity.md does not exist, stop with: Founder OS not set up here. Run /founder-os:setup first.

Scope

The wiki layer is the directories listed in scripts/_common.py:WIKI_LAYER_PREFIXES. That module is the canonical source of truth, shared by scripts/wiki-build.py and scripts/query.py so the on-disk graph and the in-memory graph cannot drift.

Skill files (skills/), templates (templates/), commands (.claude/commands/), hooks (.claude/hooks/), docs (docs/), and root metadata (README.md, CLAUDE.md, VERSION, etc.) are NOT scanned. Raw layer (raw/) is scanned only for provenance gaps (Check 4).

Check 1 - Broken cross-references

Scan all wiki files for [[link]] patterns. For each:

• If the link points to an existing file, OK.
• If the link points to a missing file, flag.
• If the link uses an ambiguous slug that matches multiple files, flag with all candidates AND name the deterministic pick. Resolution order: scan directories in the order listed in scripts/_common.py:WIKI_LAYER_PREFIXES, then alphabetical within the first matching directory. The first match wins. Format the output as [[slug]] -> ambiguous: <candidate list>; would resolve to <first match>.

[[link]] syntax accepts: [[file.md]], [[path/to/file.md]], [[page-name]] (resolves to first match across the wiki).

Check 2 - Orphan pages

For each wiki file, check whether any other wiki file references it ([[]] link, plain markdown link, or filename mention).

Pages that are intentional roots and never get linked TO are exempt:

• core/identity.md
• context/priorities.md, context/clients.md, context/companies.md, context/decisions.md
• cadence/daily-anchors.md, cadence/weekly-commitments.md, cadence/quarterly-sprints.md, cadence/annual-targets.md
• brain/log.md, brain/flags.md, brain/patterns.md, brain/decisions-parked.md, brain/needs-input.md, brain/index.md, brain/relations.yaml
• All files under roles/ (registry + role definitions; loaded by mode, not by reference)
• All files under rules/ (operating rules + entry conventions; loaded by mode, not by reference)
• All README.md files

Anything else with zero inbound references is flagged as orphan.

Check 3 - Stale time-sensitive content

Use the dated headers and frontmatter dates first. Fall back to file mtime only if no in-content dates.

Decay-convention adoption gap

For each entry in brain/flags.md (## headings) and brain/patterns.md (### headings):

• Determine the anchor date. For flags: the date in the heading line (## YYYY-MM-DD - <title>). For patterns: a First observed: line.
• If anchor date is 30+ days behind today AND the entry has no Decay after: field: flag.

Render under STALE CONTENT, prefixed decay-gap:

decay-gap brain/flags.md: "<entry heading>" - <N> days old, no Decay after: field. Suggest: Decay after: <today YYYY-MM-DD>

This is a soft suggestion, not a defect. The user may have deliberately omitted the field. Cap at the 5 oldest entries per file to avoid flooding.

brain/decisions-parked.md is intentionally excluded. The entry conventions in rules/entry-conventions.md define parked decisions as trigger-driven (no auto-decay), so a parked entry without Decay after: is the documented default, not a gap. The seeded template ships an example with no Decay after: for the same reason; flagging it would be noise on a fresh install.

Log size cap

If brain/log.md exceeds 300 lines, output under STALE CONTENT:

log-cap brain/log.md: <N> lines (cap is 300). Move oldest entries to brain/archive/log-<YYYY-MM>.md.

The cap is a writing convention (not a hard limit). This is a reminder, not a defect.

Check 4 - Provenance gaps

Scan raw/:

• Any raw file with empty wiki_pages: [] AND ingested more than 14 days ago - flag as "ingested but unused".
• Any wiki file containing [[raw/<filename>]] where the raw file does not exist - flag as "broken provenance link".

If raw/ does not exist, skip this check entirely (not all installs use ingest).

Check 5 - Possible contradictions

Heuristic, not deterministic. Flag for human review, never auto-fix.

For each decision marked resolved in context/decisions.md, check whether cadence/weekly-commitments.md (current week + previous week retro) or context/priorities.md contains text that explicitly contradicts the resolution. Examples:

• Decision resolved: "Stop building feature X." Weekly commitments contains: "Build feature X this week."
• Decision resolved: "Hire first ops lead." Priorities contains: "Defer all hires."

This is a low-confidence signal. Output as candidates, not as defects. Phrasing: Possible contradiction (review): <decision> vs <commitment>.

Check 6 - Doctrine that does not say why (advisory, one line)

python scripts/selfdoc_check.py why --json

Names the files in rules/ and system/ that never state the problem they exist to solve. A file that does not say why it exists gets ignored or misapplied by the next session that opens it, which is the quiet way doctrine stops working (rules/os-as-harness.md, property 1).

Render this as one advisory line, not a list of every file:

SELF-DOCUMENTATION (<N> files)
- <N> doctrine files carry no `why:` - run `python scripts/selfdoc_check.py why` for the list
(or: "Clean.")

Three rules keep this useful rather than noisy:

• Advisory forever. It never blocks anything and never appears in NEXT 3 MOVES unless every other check is clean.
• Forward-only. Files written before the convention adopt it the next time you touch them. Nobody backfills, and a long-standing count here is not debt.
• If the script is missing or your surface cannot run it, render SELF-DOCUMENTATION (not run - no script access). Never render Clean. for a check that did not run.

Output format

Single fenced block. Same skeleton as /founder-os:status for visual consistency.

FOUNDER OS LINT - <total findings count>
Last checked: <YYYY-MM-DD>

CROSS-REFERENCES (<N> issues)
- <file:line>: [[broken-link]] -> file does not exist
- <file:line>: [[ambiguous-slug]] -> ambiguous: <list>; would resolve to <first match>
(or: "Clean.")

ORPHAN PAGES (<N> issues)
- <file>: no inbound references
(or: "Clean.")

STALE CONTENT (<N> issues)
- cadence/daily-anchors.md: top header is YYYY-MM-DD (5 days stale)
- context/decisions.md: <decision title> pending since YYYY-MM-DD (18 days)
- decay-gap brain/flags.md: "<entry heading>" - 42 days old, no Decay after: field. Suggest: Decay after: YYYY-MM-DD
- log-cap brain/log.md: 327 lines (cap is 300). Move oldest entries to brain/archive/log-YYYY-MM.md.
(or: "Clean.")

PROVENANCE (<N> issues)
- raw/<filename>: ingested YYYY-MM-DD, wiki_pages empty (24 days unused)
- context/<file>:line: [[raw/<missing>]] -> raw file does not exist
(or: "Clean." or: "raw/ not present, skipped.")

POSSIBLE CONTRADICTIONS (<N> candidates)
- <decision> (resolved YYYY-MM-DD) vs <commitment in cadence/weekly-commitments.md>
(or: "Clean.")

SELF-DOCUMENTATION (<N> files)
- <N> doctrine files carry no `why:` - run `python scripts/selfdoc_check.py why` for the list
(or: "Clean." or: "not run - no script access")

NEXT 3 MOVES (advisory)
- <highest-priority finding to address>
- <second>
- <third>

If a section has zero findings, render a single Clean. line under that header.

If total findings count is zero, output:

FOUNDER OS LINT - 0 findings
Last checked: <YYYY-MM-DD>

Clean across all checks. Nothing to address.

Output rules

• Read-only. Never modify any file. If you find something that obviously should be fixed, name it under NEXT 3 MOVES, do not edit.
• One finding per line. No paragraphs.
• File:line references where possible. File-only references where line is not meaningful (orphans, stale headers).

Edge cases

• No wiki files yet. Output: Empty install. Nothing to lint. Run /founder-os:setup first.
• raw/ does not exist. Skip Check 4 entirely. Don't list this as an issue.
• Network/ folder missing. Skip silently - it's optional in many installs.
• Companies/ folder missing. Skip silently - some founders run a single business.
• Very large install (>1000 wiki files). Continue but warn at the top: Large install (<count> files). Lint took <duration>. Consider archiving older content.
