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 | $0.00039 | $0.00305 |
| Opus 5 | $0.00019 | $0.00152 |
| Sonnet 5 | $0.00008 | $0.00061 |
| Haiku 4.5 | $0.00004 | $0.00030 |
Grade A, and why
add-command 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 5d 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.
What it actually says
A wdd subcommand is wired in three places. To add foo:
-
src/commands/foo.ts— exportfoo(args: string[]): number | Promise<number>.- Read-only work (locate → parse → extract) goes through
resolveScope(args, process.cwd()). - Any ledger mutation goes through
applyOpsinsrc/patch/apply.ts— the single write path. Never write.wdd/ledger.jsonlanywhere else (the one exception is the distill append incommands/distill.ts). - If it writes, respect config: commit only when
config.commit === "on", and honorconfig.share.
- Read-only work (locate → parse → extract) goes through
-
src/cli.ts— add"foo"to thecommandsarray, then a routing branch that dynamic-imports and calls it (mirror the existing branches). -
Docs — add a
foorow to the--helptext insrc/cli.tsand to the command table inREADME.md.
Then run /verify (build + test). Keep the invariants in AGENTS.md intact - especially: precedent is human-ruled only, and hooks must never throw.
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.

add-command is a skill published in the GitHub repository zhu-kai/whodecided (22 stars, last pushed 1mo ago), licensed MIT. It adds 39 tokens to every session and 305 once invoked, about $0.0002 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.
