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 | $0.00064 | $0.01423 |
| Opus 5 | $0.00032 | $0.00711 |
| Sonnet 5 | $0.00013 | $0.00285 |
| Haiku 4.5 | $0.00006 | $0.00142 |
Grade A, and why
reports 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.
How it starts
The opening of the file, as written. The whole thing — 146 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Reports Skill
Contract
This skill guarantees:
- Reports saved with timestamped filenames and frontmatter
- Keyword routing: query → report category mapping
- Latest report loadable by category name
- Reports are searchable via gbrain search/query
- Outbound reports pass the Actionability Gate (below) before delivery
Phases
- Save report. Write to
reports/{category}/{YYYY-MM-DD-HHMM}.mdwith frontmatter:--- title: {report title} type: report category: {category name} date: {YYYY-MM-DD} time: {HH:MM PT} --- - Load latest. Given a category, find the most recent report file.
- Keyword routing. Map common queries to report categories:
- "email" / "inbox" → ea-inbox-sweep
- "social" / "mentions" → social-mentions
- "briefing" / "morning" → morning-briefing
- "meeting" → meeting-sync
- Custom mappings configurable
Output Format
Saved: reports/{category}/{YYYY-MM-DD-HHMM}.md
Loaded: full report content with metadata.
Actionability Gate
Before any report reaches the user — a morning briefing, a meeting digest, a
research report — every link must answer one question: can the user click
this and immediately act? The link canon (deterministic, never-guessed URLs)
lives in skills/_output-rules.md under Deterministic Links; this gate adds
the delivery-time failure taxonomy and the retry loop.
Four failure modes
| Mode | What it means | Example |
|---|---|---|
| Broken | Link is fake or a placeholder | https://example.com, TODO-find-link |
| Dead | Link to a brain page that isn't committed/pushed | Page written but not pushed — the link 404s |
| Indirect | Link goes somewhere, but not the right place | x.com/alice-example (profile) instead of x.com/alice-example/status/<id> (the specific post) |
| Missing | Actionable item mentioned with no link at all | "the clip making the rounds (~800K views)" with no URL |
Broken, Dead, and Indirect block delivery. Missing is a warning — flag it, don't block. A missing link is honest. An indirect link is a broken promise.
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.
- 3d ago First seen · 146 lines · 64 tokens per session scan A 02b67964afa4
reports is a skill published in the GitHub repository garrytan/gbrain (29,440 stars, last pushed yesterday), licensed MIT. It adds 64 tokens to every session and 1,423 once invoked, about $0.0003 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.
