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 | $0.00137 | $0.04812 |
| Opus 5 | $0.00068 | $0.02406 |
| Sonnet 5 | $0.00027 | $0.00962 |
| Haiku 4.5 | $0.00014 | $0.00481 |
Grade A, and why
discover 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 6d 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 — 488 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Open Brain Discovery (Incremental)
Analyze recent Open Brain thoughts incrementally — building on the previous report, informed by TRACKER.md priorities, with tiered light/full runs.
Prerequisites
Open Brain MCP tools must be available: list_thoughts, search_thoughts,
thought_stats, analyze, get_connections.
Verify before proceeding.
Scripts (in the skill's scripts/ directory):
adaptive_tracks.py— centroid math, pre-clustering, lifecycle, state I/Oweak_signal_score.py— OpenRouter-based weak-signal scoringparse_thoughts.py— existing thought parser
Environment variables (required for adaptive tracking):
SUPABASE_URL,SUPABASE_SERVICE_ROLE_KEY— for embedding fetchBRAIN_ID— the brain UUID (read from MCP auth context or .env)OPENROUTER_API_KEY— for weak-signal scoring
Load these from the project's pipeline/.env and openbrain/.env.local
before calling scripts:
source pipeline/.env 2>/dev/null; source openbrain/.env.local 2>/dev/null
Arguments
Parse from user message:
- days: Time window — bypasses incremental mode. Legacy fallback for one-off deep dives. Example:
/discover last 7 days - full: Force full run regardless of delta. Example:
/discover full - light: Force light pass regardless of delta. Example:
/discover light - copy: Extra save location. Example:
/discover copy to ~/Documents - focus: Narrow to specific topics. Example:
/discover focus on AI agents - --tracker: Path to tracker file. Example:
/discover --tracker STATUS.md - --no-tracker: Skip TRACKER sync entirely. Example:
/discover --no-tracker
days=N and incremental mode are mutually exclusive. If days is provided,
operate in legacy mode (no state file read, no previous report continuity).
State file is still written on completion so the next run can resume
incremental mode.
Workflow
Phase 0: Read State
Four inputs to read (in parallel where possible):
- State file: Read
DISCOVERIES_DIR/.discover-state.json.- If found: extract all fields. If it contains
tracksarray withcentroid_b64fields, this is the enhanced format — adaptive tracking is active. - If found but only has legacy fields (
last_run,last_report,thoughts_processed,run_type,tracker_hash): this is a legacy state file. Adaptive tracking will bootstrap on this run. - If not found: first run.
- If found: extract all fields. If it contains
What ships with it
3 files 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.

discover is a skill published in the GitHub repository Bobby-cell-commits/open-brain-server (8 stars, last pushed 4mo ago), licensed MIT. It adds 137 tokens to every session and 4,812 once invoked, about $0.0007 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 2026-08-31.
