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 | $0.00114 | $0.01248 |
| Opus 5 | $0.00057 | $0.00624 |
| Sonnet 5 | $0.00023 | $0.00250 |
| Haiku 4.5 | $0.00011 | $0.00125 |
Grade A, and why
search-history 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 11d 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 — 106 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Search History — Structured Document Search
Search structured wrap-up output and field notes across eight document types. Complementary to claude-history (which searches raw conversation JSONL).
Step 1: Parse Query
Extract from the user's input:
- Keywords: the search terms (everything that isn't a flag)
--typefilter (optional): one ofreports,issues,retros,memory,plans,research,decisions,evolution, orall. Default:all.--since YYYY-MM-DD(optional): only include files dated on or after this date. Applies to all dated file types (reports, issues, retros, memory, plans, research). Does not apply to Decision Log or System Evolution (single files, always searched in full). Default: no date filter.
If the input is just /search-history with no keywords, ask what to search for.
Step 2: Search Targets
Eight document types with their glob patterns:
| Type Key | Label | Glob Pattern | Dated? |
|---|---|---|---|
reports |
Session Reports | Documents/Field-Notes/Logs/*-Session-Report*.md |
Yes |
issues |
Session Issues | Documents/Field-Notes/Logs/*-Session-Issues*.md |
Yes |
retros |
Session Retros | Documents/Field-Notes/Logs/*-Session-Retro*.md |
Yes |
memory |
Memory Syntheses | Documents/Field-Notes/Logs/*-Memory-Synthesis*.md |
Yes |
plans |
Plans | Documents/Field-Notes/Plans/*.md |
Yes |
research |
Research Docs | Documents/Field-Notes/Research/*.md |
Yes |
decisions |
Decision Log | Documents/Field-Notes/Decision-Log.md |
No |
evolution |
System Evolution | Documents/System/System-Evolution.md |
No |
When --type is specified, search only that type. Otherwise search all eight.
Step 3: Execute Search
For each active document type:
- Glob to find matching files.
- For dated types (reports, issues, retros, memory, plans, research): if
--sinceis set, filter filenames by date prefix (YYYY-MM-DD>= since date). Files without a parseable date prefix are included. - Grep for keywords across the matched files. Use case-insensitive search. Request
contentoutput mode with 2 lines of context (-C 2). - For Decision Log and System Evolution (single files):
--sinceis NOT applied — always search the full file.
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.

search-history is a skill published in the GitHub repository jonathanmalkin/jules (65 stars, last pushed 3mo ago), licensed MIT. It adds 114 tokens to every session and 1,248 once invoked, about $0.0006 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.
