What is braindb-custom-profile?

Instructions for creating a BrainDB custom profile that changes wiki-writing prompts and can add a custom data source. BrainDB is a system for storing and organizing persistent knowledge.

Use it to create profile folders, add or replace maintainer and writer instructions, configure an optional ingestor, and activate profiles with an environment setting.

It lets a project tailor how information is named, structured, and imported without changing the default behavior when disabled.

NVIDIA SkillSpector warn 7 Sept 2026

SkillSpector: 4 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 Privilege Escalation · line 34
Code accesses credential files (SSH keys, AWS credentials, etc.). This could indicate credential theft attempts.

Fix: Remove references to credential paths. Use environment variables or secrets managers. For docs, use placeholder paths (e.g., /path/to/config). Never load .env or token files in production code paths.
high Prompt Injection · line 56
Hidden instructions were detected in comments or invisible text. These could contain malicious directives. Manual review is recommended.

Fix: Audit all comments and invisible characters. Remove any instructions that direct the agent to perform unauthorized actions. Use plain, reviewable content.

Data is being sent to an external URL. This could be legitimate telemetry or data exfiltration. Manual review is recommended.

Token cost

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	$0.00049	$0.01593
Opus 5.5	$0.00020	$0.00637
Sonnet 5.5	$0.00010	$0.00319
Haiku 4.5	$0.00005	$0.00159

Security

Grade A, and why

braindb-custom-profile scanned grade A with 1 finding 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 1mo ago.

The scan reads SKILL.md. This mod also ships 3 executable files (gdrive/ingestor.py, hackernews/ingestor.py, hermes/ingestor.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

How it starts

The opening of the file, as written. The whole thing — 118 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Authoring a BrainDB custom profile

A custom profile lets you (a) shape how the wiki maintainer/writer name and structure pages and (b) feed BrainDB a custom ingestion source — with zero effect on default behaviour when the profile is not active. One env switch turns a profile on; one self-contained folder holds everything it needs.

The committed custom-profiles/hackernews/ folder is a complete, keyless worked example to copy from. custom-profiles/README.md is the short contract; this is the deep how-to.

The model

One switch: CUSTOM_PROFILE in the repo-root .env names the active profile(s), comma-separated. Unset ⇒ every prompt is byte-identical to the baked-in default and the ingestor supervisor sleeps.
One folder: custom-profiles/<name>/ holds the profile's prompt fragments, an optional ingestor.py, and an optional .env.

Folder contract

custom-profiles/<name>/
├── wiki_maintainer.add.md      # appended to the maintainer prompt
├── wiki_maintainer.replace.md  # OR replaces it entirely (advanced)
├── wiki_writer.add.md          # appended to the writer prompt
├── wiki_writer.replace.md      # OR replaces it entirely (advanced)
├── ingestor.py                 # optional: a standalone source feeder
├── .env                        # optional: the ingestor's own config/secrets
└── README.md

Targets are wiki_maintainer and wiki_writer. <target>.add.md is appended to the base prompt; <target>.replace.md replaces it. With several active profiles, add fragments are concatenated in CUSTOM_PROFILE order. All files are optional.

What each prompt shapes

wiki_maintainer decides, per orphan entity: skip / create (with a proposed_name) / attach / consolidate. Shape naming and dedup here (e.g. "name companies by official name; same ticker = same company").
wiki_writer authors the page body (free markdown). Shape structure here — the sections, a labelled profile block, a dated chronicle.

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.
