Part of tinyhumansai/chottu-core#712, the epic to cut the tokens and seconds that tool calls and turns cost.

What this delivers

• RenderOptions{excerpt_chars, contents_chars, compact_sources} and RenderOptions::compact(), with render_text_with and render_markdown_with, for compact search results.
• ProviderConfig.contents_max_chars, which bounds page contents.

The defaults keep today's output. Hosts opt in.

Rolled-up PRs (merged on the fork)

• feat(render): compact search results, bounded page contents senamakel/tinysearch#6

Gates (at the epic tip, b99ebbb)

• cargo check --workspace --all-targets: pass.
• cargo clippy --workspace --all-targets -- -D warnings: pass.
• cargo test --workspace: pass.

This branch is up to date with main (0 behind). OpenHuman needs a tinysearch module release and re-pin after this merges, so its hosted CI picks up contents_max_chars.

Summary by CodeRabbit

• New Features
  • Added configurable limits for search excerpts and page content, including a compact preset that caps page content at 1,500 characters.
  • Added an option to omit source citations that duplicate listed results.
  • Provider settings can now cap the content returned for each page; requests without a configured cap continue to retrieve whole pages, with up to 1,500 characters retained.
• Documentation
  • Updated the README with details on rendering options and provider content limits.

Full summary

Pull request purpose (title): feat(render): compact search results and bounded page contents. This PR adds opt-in compactness controls without changing default output: `RenderOptions` with `render_text_with`/`render_markdown_with` (configurable excerpt caps, per-page contents caps, and source compaction via `RenderOptions::compact()`), plus `ProviderConfig.contents_max_chars`, which reaches Exa contents calls as `text.maxCharacters` on both direct and backend routes and is clamped to a 1,500-character per-page bound. Normalization now keeps up to 1,500 characters per page for contents-role tools while search snippets stay at 1,200. The latest-push delta is unavailable, so this describes the whole pull-request change.

What changed

The render module gains an `options` submodule exporting `TEXT_EXCERPT_CHARS` and `COMPACT_CONTENTS_CHARS`, and the existing `render_text`/`render_markdown` become thin wrappers over new `_with` variants that take `RenderOptions`. A new `sources` helper filters citations when `compact_sources` is on: citations whose URL matches one of the first `max_results` results are dropped, and the remainder are capped at `max_results`, with numbering preserved from the original citation list. Provider config adds `contents_max_chars` (serde round-trip, Default, and Debug redaction-consistent field), which `direct::apply_contents_cap` injects into `exa_get_contents` as `max_characters` only when the caller set none, clamped to at least 1 and at most `MAX_PAGE_CHARS`. `exa_body` converts a positive `max_characters` into `text.maxCharacters`, otherwise sends `text: true`. Normalization picks a per-role snippet cap using `role_provider_tool(Role::Contents, ...)`. README documents the render options and the provider setting.

Features

• Added — Source compaction in rendered output: With `compact_sources`, citations duplicating listed results are omitted and remaining sources are bounded by `max_results`, reducing redundancy in text and markdown output. (crates/tinysearch-bus/src/render/mod.rs, crates/tinysearch-bus/src/render/mod_tests.rs)
• Internal refactor — Debug output and serde defaults for the new config field: `ProviderConfig` Debug includes `contents_max_chars`, and legacy payloads without the field deserialize to `None`, preserving existing behavior. (crates/tinysearch-bus/src/search/types.rs impl fmt::Debug for ProviderConfig {, crates/tinysearch-bus/src/search/types.rs impl Default for ProviderConfig {)

Tests

• unit — Compaction in text and markdown: default keeps `Sources`, compact drops duplicated sources but retains non-result citations, treats results hidden by `max_results` as unlisted, and caps sources at `max_results`.: The tests assert specific rendered strings and occurrence counts of result URLs, so a regression in the `sources` filtering would surface. Test lane reported an answered status with no findings. (crates/tinysearch-bus/src/render/mod_tests.rs)
• unit — Excerpt and contents caps apply to the correct role, the default contents cap reproduces the prior 500-character output, and `RenderOptions` deserializes with defaults and round-trips.: Assertions check exact character counts and truncation boundaries for both renderers. Test lane reported an answered status with no findings. (crates/tinysearch-bus/src/render/mod_tests.rs, crates/tinysearch-bus/src/render/options.rs)
• unit — Exa request bodies ask for whole pages when uncapped, send `maxCharacters` for a positive cap, and ignore zero, malformed, or negative values.: Direct assertions on the produced body and path. Test lane reported an answered status with no findings. (crates/tinysearch/src/provider/direct/exa_tests.rs fn only_search_takes_a_type() -> Result<()> {, crates/tinysearch/src/provider/direct/exa.rs)
• integration — A configured `contents_max_chars` reaches the mock server's request as `maxCharacters` and the normalized snippet is bounded to 1,500 characters; over-large caps clamp to 1,500; search calls and caller-specified caps are untouched; search snippets stay at 1,200.: Covers both the request side and the normalized result, exercising direct and backend request building. Test lane reported an answered status with no findings. (crates/tinysearch/src/provider/mod_tests.rs async fn exa_direct_operations_map_and_normalize() -> TestResult<()> {, crates/tinysearch/src/provider/normalize.rs, crates/tinysearch/src/provider/direct/mod.rs)

• Conclusion: Success
• Scope reviewed: all assigned evidence
• Positive: Test lane reported an answered status with 0 findings, noting each behavioural branch has a test asserting actual output such as request bodies, rendered strings, and per-page character counts.
• Lane summary: This adds `RenderOptions` with `render_text_with`/`render_markdown_with` (sources compaction, configurable excerpt and contents caps), an Exa `contents_max_chars` provider setting that rides as `max_characters`, and role-aware page/citation caps in normalization. Each behavioural branch has a test asserting the actual output — request bodies, rendered strings, and per-page char counts — so a regression would surface. The changes look sound and consistent with the repository's test-layout rules.

description

• Conclusion: Success
• Scope reviewed: all assigned evidence
• Lane summary: The description matches the diff: the new `RenderOptions`/`render_*_with` surface, the `compact()` preset, and `ProviderConfig.contents_max_chars` (including the 1,500-character clamp and the default preserving today's 500-char output) are all described, and the README documents both. The change looks sound to merge; the only nit is that the body's gate list doesn't mention the repository's `cargo fmt`/`--all-features` commands, which is not a defect in behaviour.

Walkthrough

The change adds configurable text and Markdown rendering options, including compact source lists. It also adds an optional per-page character cap for Exa contents requests and applies different snippet limits to contents and search results.

Full details: Title check

Explanation

The title "feat(render): compact search results and bounded page contents" matches the main changes. The PR adds RenderOptions with compact_sources to omit duplicate source entries (compact search results). It also adds contents_max_chars and a per-page cap for Exa contents (bounded page contents). The title is specific, follows a conventional-commit style, and names both primary parts of the change. It does not describe anything absent from the changeset.

Full details: Docstring Coverage

Explanation

Docstring coverage is 43.75% which is insufficient. The required threshold is 80.00%. Docstring coverage is scoped to functions touched by this diff with cyclomatic complexity of at least 2. Documentation-only edits and deletions within surviving functions are included; unchanged diff context and fully deleted functions are excluded. Analyzed 16 functions across 11 files. (1 skipped: 1 unsupported.)

Resolution

Write docstrings for the functions missing them to satisfy the coverage threshold.

Review comments at @crates/tinysearch-bus/src/render/mod.rs:
- Around line 137-146: Update the URL comparison in the result-filtering flow
that builds `shown` and filters `numbered` so HTTP scheme and host are compared
case-insensitively while path case remains significant. Normalize only those URL
components consistently for both `result.url` and `citation.url`, preserving the
existing trimming and result limits.

Review comments at @crates/tinysearch/src/provider/normalize.rs:
- Around line 215-220: Update the snippet limit selection around
role_provider_tool so MAX_PAGE_CHARS applies only to Exa contents results; keep
MAX_SNIPPET_CHARS for non-Exa contents to preserve default output. Retain the
existing opt-in rendering path for expanded content.
