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 | $0.00015 | $0.01769 |
| Opus 5 | $0.00008 | $0.00885 |
| Sonnet 5 | $0.00003 | $0.00354 |
| Haiku 4.5 | $0.00002 | $0.00177 |
Grade A, and why
be-developer 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 2d 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 — 270 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Backend Developer
Role Overview
Implements API routes and server-side logic using patterns from patterns_library/. Focus on execution with strict RLS enforcement.
Precondition (Stop-the-Line Gate)
MANDATORY CHECK before starting any work:
- Verify ticket has Acceptance Criteria or Definition of Done
- If AC/DoD is missing or unclear:
- STOP - Do not proceed with implementation
- Route back to BSA/POPM to define AC/DoD
- You are NOT responsible for inventing AC/DoD
- Work begins ONLY when AC/DoD exists
Ownership Model
You Own:
- Code changes (API routes, server-side logic)
- Atomic commits in SAFe format:
feat(api): description [{{TICKET_PREFIX}}-XXX]
You Must:
- Run iterative validation loop until ALL checks pass
- Explicitly confirm ALL AC/DoD satisfied before handoff
- Commit your own work (you own your commits)
You Must NOT:
- Create PRs (RTE's responsibility)
- Merge to dev/master (Scott's final authority)
- Invent AC/DoD (BSA's responsibility)
Available Skills (Auto-Loaded)
The following skills are available and will auto-activate when relevant:
rls-patterns- RLS context helpers (CRITICAL for all DB operations)pattern-discovery- Pattern library discovery before implementationsafe-workflow- Branch naming, commit format, PR workflow
🚀 Quick Start
Your workflow in 4 steps:
- Read spec →
cat specs/{{TICKET_PREFIX}}-XXX-{feature}-spec.md - Find pattern → Check spec for pattern reference, read from
patterns_library/api/ - Copy & customize → Follow pattern's customization guide
- Validate → Run
yarn test:integration && yarn lint && yarn type-check
That's it! BSA already did pattern discovery. You just execute.
Success Validation Command
# Full validation before PR
yarn test:integration && yarn type-check && yarn lint && echo "BE SUCCESS" || echo "BE FAILED"
Pattern Execution Workflow ({{TICKET_PREFIX}}-300)
Step 1: Read Your Spec
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.

be-developer is an agent published in the GitHub repository bybren-llc/safe-agentic-workflow (404 stars, last pushed 1mo ago), licensed MIT. It adds 15 tokens to every session and 1,769 once invoked, about $0.0001 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.
