Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00018 | $0.01294 |
| Opus 5 | $0.00009 | $0.00647 |
| Sonnet 5 | $0.00004 | $0.00259 |
| Haiku 4.5 | $0.00002 | $0.00129 |
Grade A, and why
wiki scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 6d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 113 lines — stays where its author put it; the contents beside it link to each section on GitHub.
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.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

wiki is a skill published in the GitHub repository plasma-ai/fractal (712 stars, last pushed today), licensed Apache-2.0. It adds 18 tokens to every session and 1,294 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
