Reform the compaction blueprint so a runaway turn survives and the design
stops drifting across review rounds:
- Drop in-flight-turn protection ("layer 2"). Retention is a uniform tail→head
whole-unit walk; the only structural guard is step-alignment. A single turn
that alone exceeds the window now compacts its own early closed steps instead
of being retained verbatim (the failure mode that motivated this).
- Move auto-compaction off the agent/request waterfall onto a new awaited
agent/pre-request loop seam, fired before history derivation. Compaction
mutates the surface; the loop derives once from the result — no double-derive,
and a listener structurally cannot act on not-yet-derived messages.
- Tighten compactIfNeeded to required (session, system, model, signal).
- Enforce a single-pass convergence invariant in resolveConfig: reject configs
where summarizationMaxTokens + retainTokens exceeds the threshold, so a
compaction can never immediately re-trigger.
- Document the crash vs recoverable failure taxonomy; core session repair stays
compaction-agnostic (a log-only orphaned compact/start is inert).
- Wire dsh-compact-basic into examples/coding-agent and add a with-key
compaction e2e (compaction's first real-world exercise + runaway net).
- Rewrite the RFC to encode the blueprint and move it to implemented/.
The runaway-turn snapshot is a named deferred follow-up: dsh-llm-replay cannot
yet serve the interleaved summarization model call.

# The coding-agent plugin tree: the real coding agent. The two swappable
|
|
# backends — the DeepSeek adapter and the local bash executor — plus `hmr` for
|
|
# the dev/demo reload loop, then the stdio chat app (@deepseek-ai/dsh-stdio-
|
|
# agent), which bundles the whole agent-core spine (timer, llm, sessions,
|

# `hmr` is a leaf entry (not baked into dsh-stdio-agent): it is a Loader-only

# it. Requires DEEPSEEK_API_KEY (and optionally DEEPSEEK_BASE_URL) in the

|
|
# first. cordis.yml reads them via the `!!js` tag.

welcome: 'coding-agent ready. Give it a coding task (its tools are bash and subagent).'
|
|
systemPrompt: |
|
|
You are coding-agent, a CLI coding assistant.
|
|
|
|
Your tools are bash (plus bash_output/bash_kill for background
|
|
tasks) and subagent. Do ALL file operations through bash: read with
|
|
cat/sed/head, search with grep, write with heredocs (cat <<'EOF' >
|
|
file), edit with sed or a rewrite. Each bash call runs in a fresh
|
|
shell — pass workdir instead of cd, and never rely on shell state
|
|
between calls.
|
|
|
|
Use the subagent tool to delegate a focused, self-contained subtask
|
|
to a fresh child agent (it works in its own context and returns only
|
|
its final result) — give it a complete, standalone instruction. Use
|
|
subagent_fork instead when the subtask needs THIS conversation's
|
|
context: the child inherits the log so far.
|
|
|
|
Check the [exit code: N] marker on every command; investigate
|
|
failures before moving on. Verify your work by running the code or
|
|
tests. Keep answers brief and factual.
