tree-sitting
Symbol-level navigation of a local checkout using tree-sitter ASTs. Answers where a symbol is defined, what lines it spans, which symbols a file exposes, what a directory holds, and where a name is referenced — every answer carries exact line ranges to feed straight into a scoped read. Use for "where is X defined", "who calls X", "find the function/class named", "what's in this file", "give me the line range for", "show me the source of", "list the symbols in", or before editing a file you have not read. Each invocation auto-scans and is self-contained. Not for first-encounter repo orientation (use exploring-codebases), for what a codebase DOES rather than what it contains (featuring), for binding-resolved Python caller sets (searching-codebases), or for literal text and regex matching (plain ripgrep).

tree-sitting
Tree-sitter symbol index over a local checkout. Every result carries line
ranges, so the next step is a scoped Read.
Setup
Needs Python 3.10+ and pip install tree-sitter. On macOS, /usr/bin/python3
is 3.9 and will not work; use a Homebrew or uv Python. Grammars are bundled
for Linux x86_64 (parsers/*.so) and macOS (parsers/*.dylib).
If a file's grammar doesn't load, the file is skipped and stderr prints
WARNING: no grammar for … with the fix. Resolve that before trusting an empty
result. On other platforms, run python3 scripts/build_grammars.py (needs git
and cc). It writes to $TREESIT_PARSERS_DIR, or ~/.cache/tree-sitting/parsers/
when that is unset, and grammars there take precedence over the bundle.
Installed tree-sitter-<lang> wheels are the last fallback.
Use
scripts/treesit.py in this skill's directory scans the repo on every call
(cached on disk; invalidated when files or grammars change), prints a tree
overview, then answers the queries. Batch queries so one scan serves them all.
python3 scripts/treesit.py REPO # overview, depth 1
python3 scripts/treesit.py REPO --path=src/core --detail=full # drill in
python3 scripts/treesit.py REPO --no-tree 'find:Parser*' 'source:parse_input' 'refs:ParseState'
| Query | Returns |
|---|---|
find:PATTERN[:KIND[:LIMIT]] | symbols by name, substring or glob |
symbols:FILE | every symbol in a file |
source:SYMBOL[:FILE] | the symbol's source |
refs:SYMBOL[:LIMIT] | textual references |
imports:FILE | a file's imports |
dir:PATH | directory overview |
Flags: --depth N (-1 = all), --detail sparse|normal|full, --path DIR,
--skip DIRS, --no-tree, --stats, --no-cache, --rebuild-cache.
scripts/engine.py exposes CodeCache for use inside one Python process.
Languages: Python, JavaScript, TypeScript/TSX, Go, Rust, Ruby, Java, C, HTML,
Markdown (heading outline), Mojo. Other languages get generic extraction if
their tree-sitter-<lang> wheel is installed.

概要と使いどころ
Decide which model, effort level, and cascade shape each subagent gets, and how to keep improvement loops safe (evaluator-as-selector, stop on regression). Routes on measured cost-per-completed-task rather than per-token price, because a tier's token count varies more by task shape than price varies across tiers. Covers per-model effort semantics, the concision lever, cascade preconditions, context handoff, and watching a subagent fan-out live. Use when choosing a subagent's model or effort, when choosing how to escalate a failed attempt, or when asked which model or effort a task should get. Grounded in a 2026-07 calibration, a 2026-08 coding-cost study, a 2026-09 seeded-bug repair battery, a 2026-10 Haiku 5.5 ladder priced per spawn, and a 2026-10 retry-versus-escalation ladder on 295 SWE-bench Verified tasks; Managed Agents API specifics are operational, not calibrated.

Pre-change blast-radius report for a symbol or file. Walks tree-sitting references, augments with a plain-text scan over non-parsed files (configs, plain docs), and clusters affected sites by feature (`_FEATURES.md`) or top-level package. Use when about to refactor, rename, or delete something in a repo you don't own — "what breaks if I change `validateUser`", "who calls this", "is this safe to remove", "where is this used", "blast radius", "impact analysis". This is the CONVERGENT pre-change risk skill — for "what is this repo?" use exploring-codebases; for "where is X?" use searching-codebases.

Read Bluesky/ATProto without depending on Bluesky's AppView — interactions on a user's posts, thread replies, any repo's records, network-wide backlinks across every lexicon, an account's handle and PDS history, which collections are active network-wide, and layer-by-layer outage diagnosis. Use when bsky.app or the AppView is down or slow, when a Bluesky read returns timeouts or 5xx, when asked who liked/replied/quoted/reposted something, when pulling live Bluesky context cheaply, when reading records straight from a PDS, when asked who references a record or account anywhere on the network, whether an account has changed handle or migrated servers, or which lexicons and non-Bluesky apps are active on atproto. Complements browsing-bluesky, which routes everything through the AppView and fails when it does.
