Inline comments:
In `@internal/assistant/context_budget.go`:
- Around line 46-47: The code currently uses positiveOrDefault which treats 0 as
“unset” and re-applies defaults for ProviderReserve and SafetyMargin;
add/replace with a helper that honors explicit zero (e.g., nonNegativeOrDefault
or zeroAllowedOrDefault) that returns the policy value when it is >= 0 and only
returns the default when the policy value is negative/unset, then use that
helper for ProviderReserve and SafetyMargin (replace
positiveOrDefault(policy.ProviderReserveTokens, defaultContextProviderReserve)
and positiveOrDefault(policy.SafetyMarginTokens, defaultContextSafetyMargin) and
do the same replacement for the other occurrences around lines 135-140).
In `@internal/assistant/runtime_context.go`:
- Around line 36-39: modelFacingMessages is filtering out database.RoleCustom
(and other passthrough roles) because it calls isModelFacingRole which still
returns false for those roles; update the logic so model-facing
custom/passthrough roles are preserved: either modify isModelFacingRole to
return true for database.RoleCustom and the passthrough role constants or change
modelFacingMessages to treat database.RoleCustom (and the same passthrough roles
handled elsewhere) as model-facing (e.g., include a conditional that calls
modelFacingMessage(&message) when message.Role == database.RoleCustom). Ensure
the change is applied to all occurrences (the blocks around lines 36-39, 54-60,
66-74) so custom extension context is not dropped before request construction.
In `@internal/config/config.go`:
- Around line 67-74: The ContextConfig struct fields only have mapstructure tags
so JSON/YAML unmarshalling will use the Go field names; update ContextConfig by
adding json and yaml tags matching the existing snake_case mapstructure keys for
each field (e.g., add `json:"output_reserve_tokens"
yaml:"output_reserve_tokens"` for OutputReserveTokens,
`json:"provider_reserve_tokens" yaml:"provider_reserve_tokens"` for
ProviderReserveTokens, and similarly for SafetyMarginTokens, KeepRecentTokens,
and PreflightEnabled) so direct JSON/YAML loads and round-trips use the same
keys as mapstructure.
In `@internal/terminal/prompt_submit.go`:
- Around line 29-33: The prompt text is being recorded into history before
checking app.compacting which causes duplicates if submission is blocked; to
fix, check app.compacting first and bail out before any history recording so the
composer restoration doesn't create a duplicate entry—move the history-recording
statement(s) (the code that saves the prompt text) so they execute only after
the compacting check passes and a submission will actually be sent, leaving the
existing app.setComposerText and app.setStatus logic unchanged when returning
false.

Nitpick comments:
In `@config.example.yaml`:
- Around line 48-54: Add a documented entry for context.keep_recent_tokens to
the example config (under the existing context block) so users can see and copy
the retained-tail compaction budget; the key name must match
context.keep_recent_tokens and the value should reflect the default used by
setDefaults (or explicitly state the numeric default if known), plus a brief
comment explaining it controls the retained-tail compaction budget (how many
recent tokens to always keep) and how it interacts with
output_reserve_tokens/provider_reserve_tokens/safety_margin_tokens.
In `@internal/database/session_store.go`:
- Around line 237-247: The error returns from dataFromEntry(&entry) and
dataJSONFromEntity(&data) (and the similar spots around lines ~619-621) should
be wrapped with samber/oops context so callers know the failure came from
persisting ModelFacing vs rebuilding state; replace plain returns like `return
nil, err` with oops wraps such as `return nil,
oops.In("database").Code("decode_entry").Wrapf(err, "session_store: failed to
decode entry for ModelFacing")` for dataFromEntry errors and `return nil,
oops.In("database").Code("encode_entry").Wrapf(err, "session_store: failed to
encode entry after setting ModelFacing")` for dataJSONFromEntity errors
(consistent naming for code/domain is fine), and apply the same wrapping pattern
to the analogous returns at the other referenced location (lines ~619-621) so
all decode/encode failures include repository context.

frame and assert the actual cell colors used by the spinner/content match the

to get the lines, then render that line into a frame (via the same rendering
helper used elsewhere in tests) and assert the spinner and content cell
foreground (and background if applicable) equal compactingShimmerBrightColor()
(and any other compacting shimmer values) rather than just comparing
workingShimmerPalette(); keep the existing checks for text but add explicit
assertions on the rendered cell Color/Attribute values to ensure the renderer
applied the compacting palette.

139-163: ⚡ Quick winConsider consolidating submit tests into a table-driven format.
The file now has four separate
TestSubmit*functions (lines 72–163) that each exercise different code paths throughsubmit(). Based on learnings, table-driven tests are preferred for core behavior. Consolidating these into a single table-driven test would improve maintainability and align with the guideline, though the current structure is consistent with the file's existing style.Example structure for consolidated table-driven test

- Around line 102-104: The test currently checks numeric values from
usage.Breakdown which can be nil or missing and still return 0, producing false
positives; update the assertions to first verify the map contains the keys
before asserting their values. Specifically, in the test that uses the variable
usage and its map field Breakdown, add presence checks (e.g.,
require.Contains/require.True with a map lookup ok) for "reserve_provider" and
"reserve_safety" on usage.Breakdown, then assert their values (assert.Equal) as
before; ensure you still require.NoError(t, err) first and keep the same key
names.
In `@internal/assistant/context_compaction.go`:
- Around line 507-513: The token estimation uses the wrong prompt: replace uses
of compactionSummaryPrompt inside compactionRequestUsage with the actual dynamic
compactionSystemPrompt(plan.PreviousSummary) so the Usage field accurately
estimates tokens for the current SystemPrompt; update the call site where Usage
is set (the struct initializing SystemPrompt:
compactionSystemPrompt(plan.PreviousSummary), ThinkingLevel, CWD, Auth,
Messages, Usage: compactionRequestUsage(selectedModel, plan.Messages), Model:
*selectedModel) to pass compactionSystemPrompt(plan.PreviousSummary) (and make
the same replacement at the other compactionRequestUsage occurrence handling
update compactions) so preflight estimation uses the real system prompt.

In `@internal/assistant/context_compaction_internal_test.go` around lines 84 - 144, Combine the two planCompaction scenarios into one table-driven test (e.g., replace TestPlanCompactionFallsBackToDefaultKeepRecentTokens and TestPlanCompactionRejectsLatestCompaction with TestPlanCompaction_TableDriven) that defines cases with fields: name, entries (built via compactionTestEntry), tokenBudget, wantErr (bool), wantSummarizedNonEmpty (bool), wantKeptNonEmpty (bool), and expectedFirstKeptEntryID when relevant; iterate cases calling planCompaction(entries, tokenBudget) and assert according to the case (check err presence, plan.SummarizedEntryIDs, plan.KeptEntryIDs, and plan.FirstKeptEntryID for the latest-summary case where you must set latestSummary.CompactionFirstKeptEntryID). Leave compactionSystemPrompt test as a separate, small test (it already asserts compactionSystemPrompt contains "Update the existing compaction summary" and the previous summary text).

In `@internal/terminal/compact_commands_test.go`:
- Around line 156-159: The select waiting on client.ready in the test uses a
tight 1s timeout (case <-time.After(time.Second)) which causes flakiness on CI;
increase the async startup timeout to something more generous (e.g., 5s or 10s)
in that select so the case <-time.After(...) gives the provider more time before
calling t.Fatal("compaction should start provider request") — update the timeout
literal where the select checks client.ready to a larger duration.

- Around line 84-144: Combine the two planCompaction scenarios into one
table-driven test (e.g., replace
TestPlanCompactionFallsBackToDefaultKeepRecentTokens and
TestPlanCompactionRejectsLatestCompaction with TestPlanCompaction_TableDriven)
that defines cases with fields: name, entries (built via compactionTestEntry),
tokenBudget, wantErr (bool), wantSummarizedNonEmpty (bool), wantKeptNonEmpty
(bool), and expectedFirstKeptEntryID when relevant; iterate cases calling
planCompaction(entries, tokenBudget) and assert according to the case (check err
presence, plan.SummarizedEntryIDs, plan.KeptEntryIDs, and plan.FirstKeptEntryID
for the latest-summary case where you must set
latestSummary.CompactionFirstKeptEntryID). Leave compactionSystemPrompt test as
a separate, small test (it already asserts compactionSystemPrompt contains
"Update the existing compaction summary" and the previous summary text).
In `@internal/terminal/compact_commands_test.go`:
- Around line 101-194: The three tests (TestHandleCompactErrorUpdatesState,
TestRunCompactSessionPostsError, TestCancelActiveOperationCancelsCompaction)
duplicate setup/assert patterns for compaction state transitions; refactor them
into a single table-driven test that iterates cases (e.g., "compact error
updates state", "run compact posts provider error", "cancel active operation
cancels compaction") and for each case sets up the app state (app.compacting,
app.activeCompaction / activeCompactionState{Cancel:...}, session/client where
needed), invokes the relevant method (app.handleCompactAsyncEvent,
app.runCompactSession, app.cancelActiveOperation), and asserts the shared
outcomes (app.compacting false, app.activeCompaction nil, transcript last
message or statusMessage contains expected text); reference the existing symbols
handleCompactAsyncEvent, runCompactSession, cancelActiveOperation,
activeCompactionState, app.transcript, and statusMessage to locate code paths
and replace the three tests with table entries that parameterize inputs,
invocation, and expected post-conditions.
