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 5.1 | $0.00043 | $0.01034 |
| Opus 5.5 | $0.00017 | $0.00414 |
| Sonnet 5.5 | $0.00009 | $0.00207 |
| Haiku 4.5 | $0.00004 | $0.00103 |
Grade A, and why
enso-reference 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.
How it starts
The opening of the file, as written. The whole thing — 122 lines — stays where its author put it; the contents beside it link to each section on GitHub.
When to Use
Load this skill when:
- You need a quick reference for enso conventions or directory structure
- A user asks "what is enso?" or "how does this project work?"
- You are orienting yourself in an active enso project mid-session
- You want to see the current project status: active stories, log count, lessons
This is a read-only skill. No files are modified.
Reference
ENSO — Seam-Oriented Harness Protocol
A minimal system for managing AI agent context across sessions. Treats context as a scarce resource — load only what's needed, persist before it's lost, compact before overflow.
Key Skills
| Skill | Purpose |
|---|---|
session-start |
Start session. Loads PRD, ARCHITECTURE, LESSONS, recent logs, and detects the active story. Bootstraps new projects on first use. |
session-persist |
Close/pause session. Drafts a session log, lessons, and story updates for your review. Writes nothing until confirmed. |
read-session-logs |
Show last N session logs (default: 5). Read-only. |
enso-reference |
Show this reference. |
The Six Operations
| Operation | What It Does |
|---|---|
| Write | Persist information outside the context window |
| Select | Load only what's needed right now |
| Probe | Actively search (grep, LSP, glob) for answers |
| Compress | Summarize to fit the token budget |
| Isolate | Split work across scopes |
| Assign | Match task to the right agent |

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-reference is a skill published in the GitHub repository usefulmove/enso (2 stars, last pushed 4mo ago), licensed MIT. It adds 43 tokens to every session and 1,034 once invoked, about $0.0002 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.

capabilities
Your capability catalog — read this at boot. Lists the temporal date-range skills and the external integrations (reached via the loopback broker) available to you as a spawned worker, and exactly how to call each. Read-only. Consult it whenever you're unsure what tools/integrations you have or how to invoke them.
temporal
Resolve ANY named time window — today, yesterday, thisWeek, lastWeek, last7Days, last30Days, last90Days, thisMonth, lastMonth, thisQuarter, lastQuarter, thisYear, lastYear, last12Months — or an arbitrary range (lastNdays / lastNweeks / lastNmonths) to a concrete ISO date range relative to your run time. Read-only: no…
last30Days
Resolve "last30Days" to a concrete ISO date range relative to your run time — a rolling 30-day window ending today. Returns inclusive civil dates plus exact UTC instants so you have temporal context without computing dates by hand. Read-only: no writes, no network. Use before a "last 30 days" / trailing-month task…
md-audit
Read-only code quality audit — scan the current working directory for common issues (bugs, dead code, security hotspots, missing error handling) and return a prioritised findings report. No files are edited. Use when asked to "audit the code", "quick audit", "find issues", "code scan", or "what's wrong with this…
thisQuarter
Resolve "thisQuarter" to a concrete ISO date range relative to your run time — this quarter so far (quarter start → today). Returns inclusive civil dates plus exact UTC instants so you have temporal context without computing dates by hand. Read-only: no writes, no network. Use before a quarter-to-date task (QTD…
