Declared compatibility
Compatibility is declared by the source manifest. End-to-end runtime verification is coming, see below.
We're building live execution health for every listing: tool-call success rate, median latency, uptime, and last-checked timestamps, measured, not self-reported. It isn't live yet, so we don't show numbers we can't stand behind.
How agent discovery & health will work →About
Token & Context Discipline
A subagent exists for context management: it runs in its own window and returns only its summary to the main thread — intermediate noise (file reads, searches, logs) never enters the main context.
Warning — measured, not guessed. Each subagent re-pays its full context from scratch: in a real transcript the first turn was cache_read=0, every token cache_creation — nothing is shared with the main thread's cache. A no-op subagent (task = "reply DONE") already cost ~10k tokens with restricted tools and ~16k with full tool access; that floor is base system prompt + tool schemas, paid fresh every time. Of the always-on material only the skill listing (~2.5–3k tokens) is inherited by a subagent — the discipline (DISCIPLINE.md/CLAUDE.md) and the agent descriptions are not injected into it. So a delegation is worth it for isolation / parallelism / a clean window, or when the isolated work would otherwise cost the main thread more than that ~10–16k floor — never by default.
Rules
- Output = summary. The agent returns a short, structured summary to the main thread; it does not return raw logs / file dumps / long code.
- Move to a file. Heavy output (a plan, scan report, inventory) is written to
docs/*.md; a summary + pointer comes back. (local, in gitignore) - Delegation threshold. Noisy/heavy work (reading many files, scanning, research) → subagent. A single tool-call / small work → main thread. Concretely: if the isolated work won't save the main thread more than the ~10–16k fresh-context floor a subagent costs, keep it on the main thread — delegate for isolation, not to shave a few reads.
- Least tooling. An agent holds only the tools it needs; extras accidentally pollute the context + burn the limit.
- Lean SKILL.md. Skills load into the main context; heavy reference goes to a separate file, only when needed.
- Targeted reading. Instead of reading a whole file, pinpoint with Grep/Glob.
- Manage with /context. session-manager-csk recommends continue/handoff+clear based on the real percentage; at a phase boundary,
/clear.
