Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00030 | $0.00638 |
| Opus 5 | $0.00015 | $0.00319 |
| Sonnet 5 | $0.00006 | $0.00128 |
| Haiku 4.5 | $0.00003 | $0.00064 |
Grade A, and why
structured-code-search-mcp scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 4d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 66 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Structured Code Search MCP
When to use
Use when an agent needs to search, navigate, or extract code using structural queries — AST patterns, symbol lookups, or cross-file reference tracing — beyond what simple grep or glob can provide, via an MCP-backed code search server.
Requirements / Checks
- Prefer installed/pinned structured code search binaries over remote
npx -y ...@latestexecution. - Confirm the MCP client supports the required transport and method filtering.
- Bound any search path to the current workspace unless the user explicitly approves otherwise.
Workflow
-
Choose the right tool for the query:
Need Tool Text/boolean search across files search_codeStructural pattern (function shape, class with field) query_codeExtract a specific file, range, or symbol extract_codeList all symbols in target files symbols_code -
Bound scope before searching — set base path and default paths to the workspace. Set a result limit before running broad queries (e.g., max 20 results).
-
Iterate from broad to narrow:
- Start with
search_codeorsymbols_codeto identify candidate files. - Use
query_codeto narrow to the specific structural pattern. - Use
extract_codeto retrieve the exact code range needed.
- Start with
-
Filter methods at the server — use allowlists for read/search methods. Block write and edit methods by default; only enable if code modification is explicitly part of the task.
-
Handle transport — support stdio or HTTP intentionally; set connect and tool call timeouts.
-
Debug minimally — enable debug logs only long enough to capture connection, tool discovery, and failed calls. Disable after diagnosis.
Tool Interface (illustrative — actual names depend on your server)
search_code— text/boolean search with session dedup and result limits.query_code— AST/structural search for code shapes.extract_code— file/line/symbol extraction after search narrows scope.symbols_code— symbol inventory for target files.
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

structured-code-search-mcp is a skill published in the GitHub repository yeaight7/agent-powerups (6 stars, last pushed 1mo ago), licensed Apache-2.0. It adds 30 tokens to every session and 638 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
