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 | $0.00041 | $0.00436 |
| Opus 5.5 | $0.00016 | $0.00174 |
| Sonnet 5.5 | $0.00008 | $0.00087 |
| Haiku 4.5 | $0.00004 | $0.00044 |
Grade A, and why
forget 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 3d 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
/forget
Permanently delete a memory by its source_id.
Safety
This cannot be undone by Wenlan. Prefer /capture with supersedes pointing
at the old memory when history should be preserved.
Always confirm with the user before calling forget, unless the same user message already includes an exact id and an unambiguous delete instruction (for example they pasted the ID and said "delete this").
If the id is missing, call /recall first to find candidates or ask the user
for the exact id. The confirmation reply must include the action and id:
delete <id>
A bare id is not confirmation.
Call
After confirmation, call:
forget(memory_id="<source_id>")
Delete only one memory per tool call. For bulk cleanup, use /curate captures
so each item has its own decision.
When to use
- User says "forget this", "delete that", "that's wrong, remove it".
- User explicitly identifies a memory by ID, or confirms
delete <id>after recall found the matching memory.
When NOT to use
- For corrections, prefer storing a new memory with
supersedespointing at the old one. That preserves history. Use/capturewith thesupersedesarg instead. If your agent's trust level is below full, that write may stage for human review instead of taking effect immediately. - Bulk deletions: use
/curate capturesso each item has its own decision. - Page rebuilds: use
/distill rebuild <page-id>.
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

forget is a skill published in the GitHub repository wenlan-app/wenlan (82 stars, last pushed yesterday), licensed Apache-2.0. It adds 41 tokens to every session and 436 once invoked, about $0.0002 per session on Opus 5.5. 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 2026-10-11.
Other skills, from other repositories
forget
Delete a Wenlan memory by exact id from Codex. Destructive and confirmation gated. Invoked as /forget .
recall
Search Wenlan's local memory from Codex by query. Targeted lookup, not session orientation. Invoked as /recall .
capture
Save a durable memory to Wenlan from Codex. Use proactively when the user states a preference, makes a decision, corrects you, or shares a durable fact. Invoked as /capture .
handoff
End a Codex work session. Stores durable captures, writes a narrative session log, and automatically applies typed item-level deltas to the current Space Brief. Invoked as /handoff.
lint
Lint Wenlan memory quality and hygiene, check vocabulary, or resolve every finding into a ready repair, review item, system action, or blocker.
run-wenlan-app
Build, launch, screenshot, and drive the wenlan-app Tauri desktop app in dev mode on macOS (WKWebView) or Windows (WebView2). Use when asked to run or start the app, verify a UI change in the real running app (not just tests), or take a screenshot of it.
