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 | $0.00064 | $0.01867 |
| Opus 5 | $0.00032 | $0.00933 |
| Sonnet 5 | $0.00013 | $0.00373 |
| Haiku 4.5 | $0.00006 | $0.00187 |
Grade A, and why
project-structure 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 2d 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 — 70 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Project Structure
Compress a TS or Swift repo into one map file an agent can load whole. Backed by map.ts next to this file. TS: parse-only TS compiler, no type-check; ~8k files in ~5s; resolves the typescript package from the target repo, falling back to this skill dir. Swift: zero-dependency regex/brace-depth scanner built into map.ts (no typescript needed for pure-Swift repos). Requires Node >= 23.6 (native type stripping) or npx tsx. .ts/.tsx and .swift files are detected by extension; a repo may mix both.
Run
node <this-skill-dir>/map.ts <repoRoot> [flags]
<this-skill-dir> is the base directory of this skill as announced when the skill loads (canonical: ~/Projects/agent-scripts/skills/project-structure).
Output: one map file (default project-structure-map.txt in cwd) plus a JSON stats line (files, symbols, bytes, approxTokens) on stdout.
Flags
--out <file>— output path.--mode dense|skeleton|exports|sigs|full— defaultdense.dense: dir-grouped, one line per file:file fn:a,b ty:T cl:C c:x re:./y. Recon tier. File extensions are stripped for compactness, so a same-basename TS and Swift file in one dir share a line prefix (theoretical in practice; grep the repo to disambiguate).skeleton: one symbol per line, names only.exports: exported symbols with full typed signatures, type bodies, first doc-comment line. Refactor-decision tier. TS-only — Swift files fall back to their dense-style line (no fabricated signatures).sigs: exports but type/interface bodies collapsed to member names (only ~10% smaller than exports; rarely worth it). TS-only, same Swift fallback.full: exports + non-exported top-level symbols (markedinternal; internal consts appear only when function-valued or explicitly typed — untyped internal consts are filtered as noise). TS-only, same Swift fallback.
--include a,b,c— paths to map, relative to repoRoot (default: all top-level dirs, minus skips/boundaries). Accepts nested paths, not just top-level dirs:--include src/channels/turnmaps exactly that subtree. Headers stay repoRoot-relative, so running from repo root with--include <subsystem>is the recommended way to map a subsection.--boundary x,y— dirs listed as boundary index only: child module names + one-linepackage.jsondescriptions, no symbol content. Use for plugin/extension trees.--include-tests— keep test files and test-support infra (default: both excluded; Swift test detection is path-based:Tests?/dirs and*Tests.swift).--no-docs— strip doc comments (saves ~13% on typed modes).--fn-consts-only— drop non-function const exports (on Swift files: drops every let/var symbol — closure-valued consts are indistinguishable without type info). Caution: silently drops files whose only exports are consts (plugin definition objects, schemas, registries). Prefer keeping consts indense(names are cheap).--re-counts— collapse re-export path lists to a count (dense; saves ~10%).--max-per-kind N— cap each symbol-kind list per file with+noverflow marker (dense; 10–12 is safe).--members— Swift only (ignored for TS files): additionally emit one-level-deep methods/properties asType.member; extension members appear under their target type.--public-only— Swift only (ignored for TS files): keep only symbols whose written access isopen/public.

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.
- 2d ago First seen · 70 lines · 64 tokens per session scan A cb3a169bb404
project-structure is a skill published in the GitHub repository steipete/agent-scripts (6,580 stars, last pushed 2d ago), licensed MIT. It adds 64 tokens to every session and 1,867 once invoked, about $0.0003 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 2026-08-30.
