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 | $0.00175 | $0.01814 |
| Opus 5.5 | $0.00070 | $0.00726 |
| Sonnet 5.5 | $0.00035 | $0.00363 |
| Haiku 4.5 | $0.00017 | $0.00181 |
Grade A, and why
harness 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.

harness — self-aware, self-extending setup
claudenv is your harness: a CLI + a set of skills, connectors, memory layers and a browser bridge. This skill teaches you to connect to claudenv, understand what it already gives you, find what's missing for the task at hand, and equip it — autonomously, using claudenv's own commands. The goal is to pick the optimal harness for the work, not to do everything by hand.
Язык общения с пользователем — русский. Команды и пути — как есть.
Mode detection (FIRST step every time)
Check the system prompt for the marker Harness mode (loop).
- Marker present → LOOP mode. You are inside
claudenv loop. Self-equip without pausing, but only with CURATED (★) skills and known-safe bootstraps. Never pause to ask "поставить скилл?". The goal is law. - Marker absent → INTERACTIVE mode. Propose what you'd equip in one short block (what + why + trust level), then wait for the user before installing anything non-trivial. Installing a curated skill is low-stakes; a live one is not.
Step 1 — Introspect (understand the harness you have)
Run the self-introspection map and read it before doing anything else:
claudenv capabilities # or: npx claudenv capabilities (add --json to parse)
It reports: installed skills (~/.claude/skills/), the CLI surface, memory +
active workspace + connectors, kimi-webbridge status, project MCP servers, and
the skills registry size. This is "связаться с claudenv и понять его". If the
claudenv CLI isn't found, fall back to npx claudenv <…> or read the files
directly under ~/.claude/skills/ and ~/.claudenv/.
Step 2 — Gap analysis (what would make this task optimal?)
Compare the task to what Step 1 shows. Ask: is there a skill for this, a connector to a data source, an MCP server, a browser action, or a memory decision I should record? Pick the smallest set that actually moves the task. Don't install for its own sake.
Step 3 — Discover (find the right tool)
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.

harness is a skill published in the GitHub repository AGoldian/claudenv (10 stars, last pushed 5mo ago), licensed MIT. It adds 175 tokens to every session and 1,814 once invoked, about $0.0007 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.
