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 | $0.00587 | $0.00587 |
| Opus 5.5 | $0.00235 | $0.00235 |
| Sonnet 5.5 | $0.00117 | $0.00117 |
| Haiku 4.5 | $0.00059 | $0.00059 |
Grade A, and why
engineer-flow AGENTS.md 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 1mo 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.

Engineer Flow Agent Instructions
Use skills/engineer-flow/SKILL.md as the canonical entrypoint for engineering tasks.
Runtime Model
Engineer Flow consists of:
- one public
engineer-flowAgent Skill - 16 generalized internal engineering capabilities under
skills/engineer-flow/core/ - conditional persistent project memory under
skills/engineer-flow/infrastructure/memory-management/ - compatible user-installed external Agent Skills
- sparse specialist routing with at most 2 development specialists
- mandatory post-development security verification
Framework-specific and technology-specific expertise should come from project evidence, native stack mechanisms, or relevant external Agent Skills.
Do not add built-in framework adapters.
Routing Rules
- Start from the engineering concern, not the framework.
- Select at most 2 development specialists:
- primary
- optional support
- Prefer generalized internal capabilities for generic engineering tasks.
- Activate external skills only when task or project evidence specifically supports them.
- Do not activate unrelated external skills because of generic keyword overlap.
- Current project code and configuration take precedence over assumptions.
- Prefer the smallest correct change.
- Preserve existing project conventions where reasonable.
- Avoid unnecessary repository-wide exploration.
Memory Contract
Memory is conditional infrastructure and never consumes a primary or support specialist slot.
Use memory preflight only when prior project/session/workflow context could materially affect correctness.
Prefer a host-provided MCP memory tool when available. Otherwise use:
skills/engineer-flow/infrastructure/memory-management/scripts/memory.mjs
Current code and configuration override stale memory.
Checkpoint only durable reusable project knowledge and never store secrets, credentials, .env values, raw tokens, or personal data.
Security Contract
After development, run the mandatory security verification stage.
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.

engineer-flow AGENTS.md is an instructions file published in the GitHub repository soden46/engineer-flow (3 stars, last pushed 1mo ago), licensed MIT. It adds 587 tokens to every session, about $0.0023 per session on Opus 5.5. 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.
