tuyv Wiki
A wiki is an indexed folder tree of _index.md files. A node works with two:
- Project wiki (
$WIKI_DIR) -- shared across nodes; per-branch, reaching others only through merges (usefractal radiofor live coordination). Holds architecture, conventions, and patterns; contribute durable project-wide knowledge here. - Memory (
$MEMORY_DIR) -- this node's private knowledge base. See thememoryskill for how to maintain it.
Todo lists follow the same split: a private working checklist lives in memory; a task list other nodes should see and track lives in the project wiki. Either way it is living state -- current open items, pruned as they complete -- never an append-only log.
Run wiki --help and wiki <command> --help for the CLI (init, update, lint,
map, search, read). Always pass --path ($WIKI_DIR or $MEMORY_DIR) -- a
bare command resolves the enclosing wiki by walking up, else {cwd}/wiki, which
from the node's cwd is the project wiki at best and never memory, so an omitted
--path silently targets the wrong wiki or errors. Run
wiki update --path=<dir> after adding, moving, or deleting pages;
wiki lint --path=<dir> validates structure.
Editing discipline
Name pages and folders in ascii snake_case (command_core, not command-core)
-- both wikis enforce identifier-safe names (the project wiki's mirror the
source modules they document), so wiki lint rejects hyphens and spaces.
wiki update regenerates derived state: each page's entry line in _index.md
(name and description) is pulled from the page's own frontmatter, so fix a
desc: on the page and rerun update -- hand edits to an index line are
overwritten by the next update, and each page's H1 is rewritten to its name
unless an authored frontmatter title: supplies the heading, which update keeps
and renders as the H1 (index entry lines still show the name). wiki lint is
regenerate-and-compare: it prints the diff wiki update would apply plus any
real defects, and separates issues (must fix) from advisory notes. Work the loop
-- edit pages, wiki update, wiki lint -- until clean (clean = lint exits 0;
scripts branch on the exit code, not the prose summary); lint validates
structure, not content truth, so verify facts against your sources yourself.
Cross-linking
Cross-reference aggressively -- the links between pages are the wiki's primary
value -- but link only to pages that already exist. Sibling nodes build
their pages in parallel, so a page you would link to may not exist yet: defer
that forward link rather than emit a wikilink to a not-yet-created page. Stale
sibling links are an expected transient, not a failure -- wiki lint reports a
stale link in index or page prose as an advisory note (exit 0), so never stall
an iteration chasing them. Broken links in the generated index link block -- the
rows wiki update maintains -- are the exception: each is a hard issue, fixed
by repairing the target or removing the row with wiki update --prune. The
parent reconciles stale sibling links when children merge up: indexes
refresh mechanically at commit and merge, so its integration job is repairing or
pruning what lint reports, not rerunning wiki update -- plus refreshing any
navigation or status tables it authored (lint cannot see a stale "in flight" row
for a page that has since merged).
Wikilinks also stay inside the wiki you are writing in. A [[...]] link targets
another page in the same wiki; anything outside it -- source files, configs, or
the other knowledge base (project wiki vs. memory) -- is referenced in plain
text or backticks, never linked. wiki lint notes out-of-wiki wikilinks as
stale.
Structure
Lay the wiki out as topical folders from the start: each domain area gets a
folder with its own _index.md, and pages join the folder that owns their
subsystem. A flat root is fine below ~6-8 pages; planning more, create the
folders before the pages -- the directory tree is what makes a wiki browsable,
searchable, and navigable, and it should mirror the domain the way a good module
layout mirrors a design. A shape to aim for:
wiki/
_index.md
<subsystem>/
_index.md
<topic>.md
...
<subsystem>/
_index.md
<sub-area>/
_index.md
<topic>.md
...
<sub-area>/
...
<topic>.md
...
...
Nest deeper as areas grow: when a folder accumulates pages spanning more than
one concern, split them into sub-folders, each with its own _index.md. Every
index is the table of contents for its level, so structured nesting is what
keeps the wiki navigable at any size -- a reader answers "where does this live?"
by descending a few links instead of scanning one long list, and related pages
sit beside each other where cross-links suggest themselves.
A grown flat wiki shards into folders the same way after the fact: move related
pages into a subfolder and rerun wiki update -- indexes regenerate around the
new layout, and inbound links the move broke surface as stale-link notes to
repair. Before dumping a big tree, preflight with wiki map --stat (a one-line
size summary of what the same flags would print) and bound the dump with
--depth and --desc-limit=<n> -- descriptions print untruncated by default.
