Reduces per-turn token cost of prompt and tool metadata by ~2,160
tokens (~8.6 KB across 12 prompt files) without losing instructional
signal. Moves literal default values from description text into
TypeBox's native `default:` keyword, and updates the strict-mode
sanitizer to preserve default info for providers that strip the
keyword.

Changes are textual compression only — grammar-scaffolding removed,
redundant bullets stripped, repeated facts consolidated. All
behavioral contracts, safety rules, worked examples, and
tool-precedence directives are preserved. The system prompt retains
RFC 2119 invocation, XML tag semantics, adversarial-caller guidance,
persistence doctrine, unit-of-change and no-forwarding-addresses
rules, completeness contract, DRY-at-2, earn-every-line, trust-
internal-code, tool precedence, AST tool priority, pattern-syntax
cheatsheet (via ast-grep.md/ast-edit.md), tool persistence,
outside-in code integrity, default follow-through, and procedural
steps 1-7. AST tool docs retain the class-wrapper +
method_definition sel example (the most error-prone usage pattern).
bash.md critical section retains MUST-weight on the ast_grep /
ast_edit directives.
Schema: defaults as first-class metadata
Moved 18 literal default values from `(default: X)` description
text into TypeBox's native `default:` keyword across:
ast-edit.ts, ast-grep.ts, bash.ts, browser.ts, find.ts, gh.ts,
grep.ts, python.ts, read.ts, ssh.ts. Runtime-resolved placeholders
(cwd, pr-<number>) remain as text since they cannot be literal
TypeBox defaults.
Added:
- `minItems: 1` on ast-edit.ts `ops` array — machine-enforces what
the .md previously stated only in prose; handler already rejects
empty ops arrays, this adds the schema-level constraint.
- `find.ts` `pattern` description enriched with facts previously
only in find.md (comma-separated lists, simple patterns recurse
from cwd).
Strict-mode sanitizer: inline `default` into `description`
OpenAI's Structured Outputs strict mode rejects schemas containing
`default` with HTTP 422 ("default is not permitted"). Affects
openai, azure, github-copilot, openrouter, cerebras, together,
zenmux, and deepseek providers.
`sanitizeSchemaForStrictMode` in packages/ai/src/utils/schema/
strict-mode.ts now appends ` (default: X)` to the sibling
`description` before stripping the `default` keyword. Non-strict
providers (Anthropic, Google) still see the native keyword.
Rules:
- Inline is skipped when description already contains `(default:`
(prevents double-inlining on recursive calls)
- Inline is skipped when no sibling description exists (no
synthesis)
- Formatting: strings as-is (`cwd`), other values via
`JSON.stringify` (matches the conventional text form)
CONSTRAINTS.md documents the inlining rule alongside the existing
keyword-strip rule.
Regression tests
packages/ai/test/schema-strict-mode.test.ts gains 7 `it` blocks:
- number/bool/string default types inline correctly
- falsy defaults (`false`, `""`, `0`) are not confused with absent
- `null` default goes through JSON.stringify branch
- double-inline prevention when description already says `(default:`
- no synthesis when no description exists
- nested object property with default (recursion + cache path)
- type-array `[T, null]` branch with default on outer schema
(variant-materialization path)
23/23 schema tests pass, 541/541 ai-package tests pass,
`bun check` clean.

| Sequential first | Then | Reason |

Safe to parallelize: independent modules, isolated file-scoped refactors, tests for existing code.
{{#if contextEnabled}} **context:** ``` ## Goal ← one sentence: what the batch accomplishes ## Non-goals ← what tasks must not touch ## Constraints ← MUST/MUST NOT rules and session decisions ## API Contract ← exact types/signatures if tasks share an interface (omit if N/A) ## Acceptance ← definition of done; build/lint runs AFTER all tasks complete ``` {{else}} No shared `context` field exists in this mode.

## Goal Rename `parseConfig` → `loadConfig` in `src/config/parser.ts` and all callers. ## Non-goals No behavior or signature changes; rename only. ## Acceptance (global) Caller runs `bun check:ts` after both tasks complete. Tasks must NOT run it. ## Target - `src/config/parser.ts`: function `parseConfig` - If `src/config/index.ts` re-exports it, update the re-export - Non-goals: do not touch callers or testsChange
- Rename
parseConfig→loadConfig(declaration + any JSDoc references)
Edge Cases
- Rename all overload signatures if overloaded
- Internal helpers like
_parseConfigValueare different symbols — leave untouched - Do not add a backwards-compat alias
Acceptance
parseConfigno longer appears as a top-level export inparser.ts
Target
src/cli/init.ts,src/server/bootstrap.ts,src/worker/index.ts- Non-goals: do not touch
src/config/parser.tsorsrc/config/index.ts
Change
- Replace
import { parseConfig }→import { loadConfig } - Replace every call site
parseConfig(→loadConfig( - For
import * as cfgusers, updatecfg.parseConfigproperty access
Edge Cases
- String literals containing "parseConfig" (logs, comments) are documentation — leave them
- If a file re-exports to an external package boundary, keep the old name via
export { loadConfig as parseConfig }with a// TODO: remove after next majorcomment
Acceptance
- No bare
parseConfigidentifier remains in the three target files {{/if}}
