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 | $0.00175 | $0.01814 |
| Opus 5 | $0.00088 | $0.00907 |
| Sonnet 5 | $0.00035 | $0.00363 |
| Haiku 4.5 | $0.00017 | $0.00181 |
Grade E, and why
harness scanned grade E with 3 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 5d 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.

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 2mo ago), licensed MIT. It adds 175 tokens to every session and 1,814 once invoked, about $0.0009 per session on Opus 5. A static security scan graded it E with 3 findings (downloads and executes remote code, recursive force delete, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.

memory
Use durable BB memory when prior project knowledge or cross-project user preferences can improve the current task, and save durable new learning through the bb memory CLI.
workflows
Execute a workflow script that orchestrates multiple subagents deterministically. Use when the user explicitly requests a workflow, multi-agent orchestration, parallel or sequential agent pipelines, structured agent outputs, or a durable background workflow run.
submit-a-plugin
Submit a bb plugin to the BB Community marketplace. Use whenever a user asks to submit, list, publish, or add a plugin to the BB marketplace, or asks for a marketplace pull request. This skill validates the plugin and release, creates the marketplace entry, icon, screenshots, and long-form overview, and opens the pull…
secrets
Securely request API keys, access tokens, passwords, webhook secrets, or other credentials and write them to a dotenv file without exposing their values to the agent. Use whenever a task needs a credential that the user must supply.
analyze-bundle
Convert Next.js bundle analyzer data to NDJSON and explore it.
regex-mastery
Use this skill when writing regular expressions, debugging pattern matching,optimizing regex performance, or implementing text validation. Triggers on regex, regular expressions, pattern matching, lookahead, lookbehind, named groups, capture groups, backreferences, and any task requiring text pattern matching.
