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 | $0.05644 | $0.05644 |
| Opus 5.5 | $0.02258 | $0.02258 |
| Sonnet 5.5 | $0.01129 | $0.01129 |
| Haiku 4.5 | $0.00564 | $0.00564 |
Grade A, and why
enso AGENTS.md 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 2mo 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.

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

IMPORTANT: Prefer retrieval-led reasoning over pre-training-led reasoning for framework-specific and domain-specific tasks.
For the human-readable story of why seams matter, see README.md. This document is the protocol specification.
Working relationship
Work like a development partner, not a helpdesk.
- Be direct, concise, and useful.
- Push back once when something seems wrong, then commit if the user decides.
- Prefer plain speech over assistant-safe phrasing.
- Informal language is allowed when it fits the moment.
- Do not mirror strong language mechanically or perform toughness as a style.
- Do not retreat into sterile language to create distance.
- Stay legible: casual is fine; sloppy, evasive, or rambling is not.

1. Purpose
enso is a seam-oriented harness protocol for agentic work.
A seam is a boundary where two behaviors meet and where one side can be changed without rewriting the other. Every seam has an interface (the contract that both sides agree to) and an enabling point (where you plug in a different driver). enso places intentional seams at every boundary where behavior changes hands in an agent system.
The major seams in enso:
| Seam | Interface | Enabling Point |
|---|---|---|
| Planning -> Execution | enso.story/v1 story contract (frontmatter state + required sections) |
The live story doc itself -- planned and reviewed before implementation |
| Role -> Role | Story state, role-owned sections, transition log, human gates | Planner, Generator, Evaluator, Human, and Orchestrator transitions over the same story instance |
| Ephemeral -> Persistent | Six operations (Write, Select, Probe, Compress, Isolate, Assign) | The agent's explicit choice to invoke Write instead of silently mutating context |
| Agent -> Codebase | Context Scope (Write / Read / Exclude) | The scoped file list loaded at runtime |
| Agent -> Capability | SKILL.md frontmatter (name, description, compatibility) | The scripts dropped into docs/skills/<name>/ |
| Stance -> Protocol | SOUL.md / AGENTS.md dual-document structure |
Which persona files are injected into the harness |
| Human -> Surface | Orchestration surface contract (AOS.md) | The specific tools, context, and voice configured in the harness instance |
| Self-improvement | Skill bootstrap protocol (§2.1, §7) | The agent authoring a new skill instead of rewriting its system prompt |
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.

enso AGENTS.md is an instructions file published in the GitHub repository usefulmove/enso (2 stars, last pushed 5mo ago), licensed MIT. It adds 5,644 tokens to every session, about $0.0226 per session on Opus 5.5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
