GBrain is a memory and retrieval layer for AI agents that searches, connects, and synthesizes information from stored sources. It is used to give coding agents and autonomous agents access to knowledge beyond their current code, including shared company information with access controls. The catalogue add-ons help agents operate GBrain and connect it to agent workflows.
Getting it into your agent
It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

- NVIDIA SkillSpector warn
SkillSpector: 2 findings, up to high
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →
- high System Prompt Leakage · line 28 Skill contains instructions that could directly expose system prompts, internal rules, or hidden instructions to users or external parties.Fix: Remove any instructions that reveal, print, or output system prompts or internal rules. System instructions should never be exposed to end users.
- medium Excessive Agency · line 175 Skill enables autonomous high-impact decisions without human-in-the-loop verification. Critical operations (destructive commands, financial transactions, data deletion) should require explicit user confirmation.Fix: Add human-in-the-loop confirmation for destructive, irreversible, or high-impact operations. Never auto-execute commands that modify files, send data, or alter system state.
What it costs to keep this loaded
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 | $0.00067 | $0.01544 |
| Opus 5 | $0.00034 | $0.00772 |
| Sonnet 5 | $0.00013 | $0.00309 |
| Haiku 4.5 | $0.00007 | $0.00154 |
Grade A, and why
citation-fixer 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 9d 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 — 209 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Citation Fixer Skill
Convention: see conventions/quality.md for the canonical citation format every fix should match.
Output rule: all links MUST be deterministic (built from API data, not composed by LLM). See _output-rules.md.
Contract
This skill guarantees:
- Every brain page is scanned for citation compliance.
- Missing citations are flagged with specific location.
- Malformed citations are fixed to match the standard format.
- (v0.25.1) Tweet / post references without URLs are resolved via
X API and patched with deterministic
https://x.com/<handle>/status/<id>links. - Results reported with counts (scanned, fixed, remaining).
Phases
- Scan pages. List pages and read each one, checking for inline
[Source: ...]citations. - Identify issues:
- Facts without any citation
- Citations missing date
- Citations missing source type
- Citations with wrong format
- (v0.25.1) Tweet references without
x.comURLs
- Fix format issues. Rewrite malformed citations to match
conventions/quality.md. - (v0.25.1) Resolve tweet references via the X API integration.
- Report results. Count: pages scanned, citations found, issues fixed, tweets resolved, remaining gaps.
Tweet resolution pipeline (v0.25.1 extension)
For each broken tweet reference, follow this chain. The actual API call
goes through whatever X integration the host has configured (typical
shape: a recipe under recipes/x-api/ with handle / search-all
endpoints).
Step 1: Identify broken references
Scan the page for patterns that indicate tweet references without URLs:
- Contains words like
tweeted,posted,said on X,RT,retweet,X post - Contains quoted text that looks like a tweet (short, punchy, often starts with a quote)
- Has
[Source: ... X/Twitter ...]without anx.comURL - References engagement metrics (likes, impressions) without a link
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.

citation-fixer is a skill published in the GitHub repository garrytan/gbrain (29,702 stars, last pushed today), licensed MIT. It adds 67 tokens to every session and 1,544 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.
