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 5.1 | $0.00042 | $0.01253 |
| Opus 5 | $0.00021 | $0.00626 |
| Sonnet 5 | $0.00008 | $0.00251 |
| Haiku 4.5 | $0.00004 | $0.00125 |
Grade A, and why
archi-brief-scan 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 11d 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 — 96 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Invocation
- Auto-invoke: No, not triggered by model based on description.
- Trigger location: Only explicitly called via
[[SUBAGENT]]/[[NO-SUBAGENT]]in/archi.*protocols. - Execution context: When subagent supported must execute in independent subagent/independent context; only downgrade to inline Skill when no subagent.
- Boundary: Only return protocol-required structured artifacts, subsequent write, confirm and signoff handled by calling protocol.
Design Conventions
- No Side Effects: Do not write files, do not execute commands
- Parse + Scan + Check Three-in-One: Brief location / Asset inventory / External reference reachability completed in one pass
- User Interaction Extracted: unreachable only output as field to main agent, this skill does not do [A/B/C] Gate
- Missing Exits: When Brief completely doesn't exist return
{ status: "no_brief" }, caller decides next steps
Execution Phases
step_a_locate Locate Brief
- If caller passes
brief_path→ Use that path - Otherwise search in following order, take first existing non-empty file:
project-brief.md(project root directory)[[__DOCS_DIR__]]/project-brief.md
- If none exist or all candidates empty → Return
{ status: "no_brief" }and exit
Output: brief_file_path or no_brief status.
step_b_asset_scan Asset Inventory and Reachability
Prerequisite: step_a successfully obtained brief_file_path.
b.1 brief-assets/ directory scan: Check if brief-assets/ exists in project root, if exists recursively enumerate all files, record path and type (image / pdf / json / md / schema / txt / other). Read content of readable files; binary only record meta info (type + size).
b.2 Brief full text external reference scan: Match Markdown links [text](URL) / , bare URLs https?://..., relative paths ./... / ../.... For each reference determine type:
| Type | Determination | Handling |
|---|---|---|
brief-assets/ local file |
Path starts with ./brief-assets/ or brief-assets/ |
Match with b.1 results, mark [reachable-local] |
| Public HTTP(S) URL | Accessible (no auth) | Try to read, success mark [reachable-remote], failure mark [unreadable] |
| Auth-required link | Returns 401/403 or Notion/Google Drive private link | Mark [unreadable-auth-required] |
| Dead link | 404/timeout | Mark [unreadable-dead] |
| Pure descriptive reference | Not real URL (e.g. "refer to iOS HIG guidelines") | Mark [descriptive-no-access-needed] |
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.

archi-brief-scan is a skill published in the GitHub repository JiuNian3219/architext (14 stars, last pushed 3mo ago), licensed MIT. It adds 42 tokens to every session and 1,253 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 2026-08-30.
