- fromRequest placeholder: the last two braces of a consecutive } run now
terminate the placeholder, so patterns may end with a brace quantifier
(bot warning; the truncated pattern could even silently mis-match since
an unclosed { is literal in JS regexes)
- document that derived JSONL entries pass through the same resolution
- widen ToolRunContext/deferContext seam docs beyond composite-only usage
(source JSDoc, README pair, core-data-structures type-equiv blocks)
- pin direct-human blocked as uninstructed, completing the
goal-round/direct-human x complete/blocked test quadrant
The 60k oneOf-object test had only one object node (the innermost), so the
pre-fix code called allocateClassName once — linear, never tripping the
timeout, so it did not cover the class-name Θ(depth²) it named. Give every
level an object branch (both oneOf arms are objects) so each level propagates
a one-segment-longer class name; the pre-fix rope slice is then Θ(depth²)
(~9.5s, past the 5s default) while the capped path stays linear. Also extract
the shared cap expression into capClassNameBase (used by allocateClassName and
childClassName). py-types.ts stays at 100% per-file coverage.
The oneOf perf fix left a second Θ(depth²): a deep oneOf chain whose branches
are named objects propagated an ever-growing ConsString as the class-name
base, which allocateClassName then re-materialized (.length/.slice) at every
level. A childClassName helper now caps the base AT PROPAGATION, so each level
is O(1) and the walk is linear; the collision counter still makes truncated
bases unique. Also reword the oneOf comment (it said `+` but the code uses a
template literal — both are ConsString) and strengthen the tests: the deep
oneOf test now runs 100k levels (a quadratic regression trips the 5s timeout),
plus a 60k oneOf-object chain and a >120-char tool-name cap case. py-types.ts
stays at 100% per-file coverage.
A deep oneOf chain joined the accumulated union string at every level
(Array.join forces materialization), making it Theta(depth^2) — a
50,000-level chain took ~7.6s. Concatenate with `+` instead: V8 builds a
lazy ConsString that materializes once at the root, matching the array
arm's template-literal laziness and ts-types' composable-document approach.
The whole walk is now linear in depth. Adds a 20,000-level oneOf test
alongside the existing deep-array one; py-types.ts stays at 100% coverage.
The SDK_RENDERERS JSDoc kept the circular "a renderer here … plus the
renderer itself" phrasing the note already fixed, and its
{@link RUN_CODE_FLAVORS} pointed at a non-exported const in another module
(unresolvable). Reword to "an entry here and a RUN_CODE_FLAVORS entry in
code-mode.ts … plus the renderer function this table points at".
Follow-ups from the bot's review of the trusted-after-validation revert:
- renderType's Frame now carries JsonSchemaNode (the root schema is asserted
before any frame is built), dropping the `as Record<string, unknown>` casts,
the `node.oneOf as unknown[]` cast, and the runtime `required` filter — the
same typed-frame shape as the sibling ts-types renderer, so the "symmetric
with ts-types" claim holds structurally, not just behaviorally.
- The language-dispatch note broadens the trusted-input argument to cover all
real sources (first-party defineTool/raw registration and wire-derived plain
JSON), and the zh side uses full-width punctuation per translation-rules.md.
py-types.ts stays at 100% per-file coverage.
Rounds 6-9 of the bot review kept finding adjacent hostile-getter variants
(post-validation cycles, TOCTOU on const/enum/oneOf, self-referential
functions) because the renderer had grown per-shape runtime defenses the
sibling ts-types renderer does not have. Those inputs are unreachable: the
schema is a first-party defineTool object literal that already passed
assertSupportedJsonSchema, and per AGENTS.md "Trust TypeScript at typed
same-process seams" a typed same-process seam does not add hostile-input
handling for values the static interface forbids.
renderType now validates the whole tree once and trusts it, wrapping the walk
in one try/catch that degrades to Any — byte-for-byte the stance of the
ts-types sibling. This removes the cycle-tracking (activeSchemas/hasIdentity),
the const/enum/oneOf read snapshots, the isPyScalar re-check, the typing
rollback, and the pyScalar null->None re-read handling; the corresponding
hostile-getter tests are removed. Behavior fixes that hold for legitimate
input are kept: RESERVED soft-keyword exclusion, closed-empty-object TypedDict,
class-name cap + per-base collision counter, BigInt digits for beyond-safe
integers. py-types.ts stays at 100% per-file coverage.
The language-dispatch Agent Note documents the stance and its symmetry with
ts-types so the boundary is not re-litigated.
Address ds-review-bot v5/v6 review round 8. The prior guards re-read a
stateful getter's value between the check and the spelling, so a getter
returning different values across reads could still emit invalid Python:
- renderConstrainedScalar reads node.const ONCE into a local, then checks and
spells that snapshot; a third-read switch can no longer produce
Literal[[object Object]].
- The enum path snapshots via [...raw] (reading each element exactly once,
covering accessor-property elements) and requires the snapshot be a non-empty
all-scalar array; an emptied re-read no longer spells Literal[], and a
non-array re-read degrades.
- The oneOf branch build guards a non-array or empty re-read to Any instead of
joining to '' (a missing type).
- pyScalar spells null as None; its JSDoc no longer claims null cannot reach it.
Tests cover each re-read shape; py-types.ts stays at 100% coverage.
Address ds-review-bot v5/v6 review round 7:
- The render-walk cycle guard tracked only plain objects; a function has
typeof 'function' yet carries own properties and can reference itself, so a
post-validation getter returning a self-referential function bypassed the
guard and looped forever. A hasIdentity() helper now covers objects AND
functions, applied symmetrically at the three sites (root add, finish remove,
child check).
- renderConstrainedScalar re-reads const/enum at render time; a stateful getter
that validated as a scalar could return an object, spelling the invalid
Literal[[object Object]]. It now degrades to the broad type when the re-read
value is not a scalar (or the enum not an all-scalar array).
- The activeSchemas comment notes the out-of-scope boundary: a getter
fabricating a fresh node per read never repeats an ancestor and is
indistinguishable from a legitimately unbounded-depth schema.
Tests cover the function cycle and non-scalar const/enum re-reads; py-types.ts
stays at 100% per-file coverage.
Address ds-review-bot v5/v6 review round 6:
- renderType tracks the active ancestor schemas by object identity (the frame
stack is the DFS path). A stateful getter can mutate the graph after
validation so a child returns an ancestor at render time; without this the
walk pushed frames forever instead of degrading. A repeated ancestor now
degrades to Any, honoring the never-throw contract; distinct nodes in a
legitimately deep chain are different objects, so it stays O(1) per push and
O(depth) memory.
- The multiline allocateClassName JSDoc was still attached to the
MAX_CLASS_NAME_BASE constant (a self-referential @link, and the function had
no doc). Move the doc onto the function and give the constant its own
one-liner.
- Tests cover the post-validation cycle and a non-object render-time child;
py-types.ts stays at 100% per-file coverage.
Address ds-review-bot v5/v6 review round 5:
- allocateClassName: keep a per-base collision counter (state.nextClassCounter)
so a deep single-field chain sharing one capped base allocates in amortized
O(1) instead of rescanning from 2 each time (Theta(depth^2) time); remove the
stale one-line JSDoc left above the multiline one and attach the doc to the
function, not the constant.
- renderType's catch rolls back the typing symbols the discarded subtree added
(not just the classes) so the import line still lists exactly the symbols the
surviving output uses; the comment now names that the same path also degrades
this module's internal-invariant throws to Any, the trade for never throwing.
- README (both languages) no longer describes an installable
dsh-code-runtime-python package: the Python renderer is built in and drives
any runtime reporting language: 'python'; the first-party backend ships
separately.
- Tests: assert the render-phase degrade on the first call, assert the import
line after rollback, and cover the collision-skip loop; py-types.ts stays at
100% per-file coverage.
Address ds-review-bot v5/v6 review round 4:
- renderType now holds the no-throw contract across the whole walk, not
just root validation: a stateful getter that passes validation and then
throws in the render phase degrades the node to Any, rolling back any
classes the call had begun emitting, instead of escaping.
- allocateClassName caps the accumulated base name. Child class names
derive from their parent's, so an unbounded single-field object chain
grew the sum of names to Theta(depth^2) (a 5000-deep schema produced a
~25MB SDK); the cap keeps total emitted text linear, the collision
counter still makes truncated bases unique.
- The language-dispatch note's Consequences first sentence and the zh
guard paragraph are corrected: two table entries (not one), and
full-width Chinese punctuation per translation-rules.md.
Address ds-review-bot v5/v6 review round 3:
- Config.mode JSDoc and the regenerated config-catalog no longer claim Code
Mode requires a TypeScript runtime; both now say a language with a
registered SDK renderer.
- The active 2026-06-15-code-mode base note (both languages) follows shipped
reality: the SDK renders the loaded runtime's language, dsh-tools accepts
any language with a renderer and run_code flavor, and it cross-links the
language-dispatch note.
- The language-dispatch note distinguishes the two Object.hasOwn guards'
reachability and documents the peekRuntime no-runtime degrade vs the
rejected silent fallback.
- SDK_RENDERERS comment: adding a language is two table entries, not one.
- py-types: document the deliberate PEP 586 deviation for float Literals;
add oneOf-object-branch tests (named union classes and context-free
degrade), keeping py-types.ts at 100% per-file coverage.
Implements the durable-subagent-catalog RFC: SubagentControlService.listChildren()
enumerates a parent's direct continuable children from one sessionQuery trace,
validates each child's sole subagent/descriptor event (now carrying the durable
creation label), and returns one ordered SubagentListEntry[] with per-child
corrupt/unsupported/unavailable diagnostics. The list_agents tool ships as a
separately loadable plugin of dsh-tool-subagent-control requiring sessionQuery
at load; send_message stays usable without it.
Implement the continuable background subagents RFC: a durable child
session with a series of Task-backed activations, each disposing its
run before the Task settles.
- dsh-subagent: rename SubagentRun.sendMessage to strict steer, drop
run-level resume, add SubagentProvider.resume dispatch via
SubagentService.resume, the continuation start field, and the
versioned model-hidden subagent/descriptor session event.
- dsh-subagent-inprocess/-spawn/-fork: publish the control-allocated
child id, append the descriptor inside the initial turn, implement
cold resume from the child's own transcript under the live parent
scope, and strict running-only steer.
- dsh-subagent-control (new): SubagentControlService owning stable
child ids, descriptor snapshot/fold/authorization, Task-backed
activation with settle-then-dispose ordering, the process-local
active-run association, and steer-or-resume sendMessage routing.
- dsh-tool-subagent: background route branches on the provider's
resume capability (continuable via the control service; one-shot
task for ACP), returning both child and task ids.
- dsh-tool-subagent-control (new): the globally named send_message
tool rendering steered/started routes.
Keyless coverage spans Task ownership and disposal ordering, running
delivery, cold follow-up, descriptor rejection and rollback, known-id
reconstruction, kill during lookup, admission races, and a new
subagent-continuable ACP snapshot scenario.
- jscpd: the executor/tool mirror dsh-bash-local/dsh-tool-bash by design
(Agent Note), so the mirrored regions carry explicit ignore markers with
reasons instead of being flagged as duplication.
- pwsh-local: a self-terminated process reports SIGTERM or SIGKILL on
POSIX (PowerShell's Stop-Process choice), not only SIGTERM.
- gen-tool-catalog.spec: the shipped-tool completeness list gains 'pwsh'.
Address ds-review-bot v5/v6 review on the Python SDK renderer:
- resolveFlavor now takes a peekRuntime() reader: undefined (no runtime,
the doc-catalog harvest) degrades to the TS flavor, but a mounted
runtime whose language is absent from RUN_CODE_FLAVORS fails loud. This
removes the try/catch that silently swallowed the invalid-language path
and drops the /* v8 ignore */ that hid the flavor guard from coverage;
wireSchemas validates the runtime before projecting schemas so the
renderer-table rejection stays the canonical assembly error.
- py-types RESERVED drops the soft keywords match/case: they are legal as
TypedDict fields and methods, so keeping them needlessly degraded
common search/regex arg objects to dict[str, Any].
- py-types treats an object with omitted properties as {} like the unified
validator and TS renderer do, so a closed empty object declares an empty
TypedDict instead of a permissive dict[str, Any].
- README: symmetric jsonSchemaToPy->Any note; a stale zh SDK bullet and
limitation corrected; link the service-wide-language limitation to its
Agent Note.
Address ds-review-bot suggestions on the Python SDK renderer PR:
- resolveFlavor: widen the JSDoc and catch comment to name the
invalid-language path the doc-catalog harvest also degrades through.
- wireSchemas: note the requireCodeRuntime() call is an intentional
single gate, redundant with the per-getter resolveFlavor path.
- README: link the service-wide-language limitation to its Agent Note,
and correct the Chinese bullet that still claimed TypeScript-only.
- Delink dsh-code-runtime-python README references (that package ships in
a later PR of the split; keep the package name unlinked meanwhile).
- Add the mandatory `## Alternatives considered` and `## Consequences`
sections to the language-dispatch Agent Note.
- Regenerate config/cordis catalogs and the event graph for the shifted
index.ts source lines; re-record the README and note i18n pairings.
Code Mode generated only a TypeScript SDK and rejected any runtime whose
language was not "typescript". Add py-types.ts (jsonSchemaToPy /
renderToolsSdkPy) and select the SDK-section renderer and the run_code
schema flavor by ctx.codeRuntime.language through two parallel tables
(SDK_RENDERERS, RUN_CODE_FLAVORS), read with Object.hasOwn and failing
loud on a language with no renderer. The tool layer depends only on the
code-runtime seam's language field, so it lands independently of the
Python protocol and backend.
An empty read window (byte cap below the first selected line: `lines: []`
with `totalLines > 0`) dropped `offset` from the persisted presentation
meta, so a replayed read card could not report where the window starts or
where a continuation resumes. Carry `offset` on `FsReadMeta`,
`ReadResultView`, and the `presentationMeta` projection, and validate it in
`readMetaFromMeta` (1-based integer; the first line number may not fall
below it). Re-record the ACP fixtures and the cordis api catalog.
Also correct the Note's `parallel-file-reads` golden path
(examples/tui-agent -> apps/cli) and record the pre-card replay-degradation
tradeoff in the Decision section.
Address the review of the search render card:
- The search result view carries no `content`: it was a no-op for every
consumer and serialized the whole search text twice. A UI without a search
card falls back to the raw tool/result content; the TUI stays byte-identical
to the pre-search-card generic fallback.
- Bound the serialized presentationMeta with a configurable searchMetaMaxBytes
(default 64 KiB): the inline item cap does not bound bytes, and spill-policy
only shrinks content, never meta. capMetaBytes drops trailing groups/paths.
- Share one retention pass (retainGrepMatches/retainGlobPaths in search-core)
between the model-facing render and the meta projection; remove the second
cap/preview implementation and the presentation<->grep module cycle by
moving GrepMatch/previewLine to search-core.
- Rename the result-view discriminant kind -> shape so it no longer collides
with GenericCallView.kind (ToolCallKind, whose values include 'search').
- Narrow the entry export surface to consumed symbols.
- Sync the three bilingual ToolResultView doc pairs and the Agent Note pair;
document the deliberate empty-card acceptance vs diffsFromMeta.
- Regenerate config/tool/cordis catalogs for the new config field.
Address the code-review bot findings on the web result card:
- web_fetch's card truncated now derives from the shared renderFetchOutput
helper, matching the effective truncation the model-facing text reflects
(provider cap, source cut, or output cap), instead of the provider-only flag.
- Drop the redundant content copy from both web result views; a UI without the
web capability falls back to the raw tool/result content. Narrow the TUI
transcript view.content access accordingly.
- Set the result-state title from the call args (query/url) so a window-
truncated replay keeps a title.
- Project meta from the seam result types rather than hand-rolled value types.
- Sync the card vocabulary across core tools README, docs/core-data-structures,
the adding-a-tool cookbook, and the tool-web package README (both languages,
re-recorded pairings); regenerate the cordis api-catalog and cordis-inspect
snapshot; revise the Agent Note.
readMetaFromMeta narrows the opaque persisted meta boundary, so beyond
shape it now rejects replayed JSON that is well-typed but semantically
invalid: line numbers must be 1-based integers, totalLines a non-negative
integer, and line numbers must strictly increase without exceeding
totalLines. Any violation declines to the generic fallback.
Sync the public ToolResultView contract across the core/tools and
tool-fs READMEs and docs/core-data-structures/tools for the fourth
result-view member and the ReadFileLine vocabulary, and expand the
Agent Note Testing section with the new rejection paths and the snapshot
evidence this PR carries.
web_search and web_fetch returned only model-facing text, whose markdown source
list is lossy (title-or-hostname label, snippet and date concatenated), so a
client could not recover the structured sources. Add a card:'web' result view
with a kind discriminant ('search' carrying structured sources + answer +
truncated, 'fetch' carrying url + statusCode + truncated), projected through
each tool's output.presentationMeta and read back in presentResult. A UI
without the web card falls back to content; the TUI is unchanged. The web
consumer is a follow-up.
grep and glob returned only model-facing text; the structured matches/paths
never reached the client. Add a card:'search' result view with a kind
discriminant ('matches' grouped by file for grep, 'paths' for glob), projected
through each tool's output.presentationMeta and read back in presentResult. The
projections re-apply the same inline cap and per-line budget as the render text
and report total + truncated, so a UI never presents a capped page as complete.
A UI without the search card falls back to content; the TUI is unchanged. The
web consumer is a follow-up.
The read tool's result carries structured numbered lines, but only the
model-facing envelope text reached the client. Add a card:'read' result view
(ReadResultView) projecting {path, lines, totalLines, lang} through the tool's
output.presentationMeta so presentResult reproduces it on live and replay
paths; the pending call stays a generic read card. A UI without the read
capability falls back to the envelope-stripped content, so the TUI is
unchanged. The web consumer that renders the line-numbered view is a follow-up.
