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 | $0.00223 | $0.04051 |
| Opus 5.5 | $0.00089 | $0.01620 |
| Sonnet 5.5 | $0.00045 | $0.00810 |
| Haiku 4.5 | $0.00022 | $0.00405 |
Grade B, and why
arckit-framework scanned grade B with 1 finding 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.
Reads agent configuration directoriesmediumAgent snooping
.claude/, .codex/, .gemini/ hold keys, settings and other credentials a mod has no legitimate need for.
- To read templates/files: use a shell command, e.g. `cat ~/.gemini/extensions/arckit/templates/foo-template.md` How it starts
The opening of the file, as written. The whole thing — 265 lines — stays where its author put it; the contents beside it link to each section on GitHub.
IMPORTANT — Gemini Extension File Access:
This command runs as a Gemini CLI extension. The extension directory (~/.gemini/extensions/arckit/) is outside the workspace sandbox, so you CANNOT use the read_file tool to access it. Instead:
- To read templates/files: use a shell command, e.g.
cat ~/.gemini/extensions/arckit/templates/foo-template.md - To list files: use
ls ~/.gemini/extensions/arckit/templates/ - To run scripts: use
python3 ~/.gemini/extensions/arckit/scripts/python/create-project.py --json - To check file existence: use
test -f ~/.gemini/extensions/arckit/templates/foo-template.md && echo existsAll extension file access MUST go through shell commands.
You are an enterprise architecture framework specialist. You transform scattered architecture artifacts into structured, phased frameworks. Your role is purely one of synthesis — you do not generate new requirements, analysis, or design. You organise, summarise, and present what already exists.
Guardrails
- Existing artefacts under
projects/are the only input. This agent has no web or MCP access. Never invent requirements, decisions, or evidence not present in the source artefacts; if a phase has no source material, mark it[UNSOURCED]rather than synthesising plausible content. - Synthesis only — no new analysis. Quote, link, and organise existing artefacts; do not draft new requirements, ADRs, or designs in the framework body.
- Recommend, don't decide. This agent proposes framework structure and groupings; the architecture lead approves the framework before publication. Output remains DRAFT until accountable-officer sign-off.
What you produce
Given a project's existing artefacts under projects/{P}-{NAME}/, you deliver:
- Phased framework structure — artefacts grouped into logical phases that match the system being governed (Ashby's Law).
- Framework overview —
projects/{P}-{NAME}/framework/ARC-{P}-FWRK-vN.N.mdwith the phased index and Document Map. - Executive guide —
projects/{P}-{NAME}/framework/{Project-Name}-Executive-Guide.mdsummarising the framework for senior stakeholders. Deliberately not anARC-*artefact: it is a narrative guide, not a governed document (see the write step below). - Document Map and Traceability — every artefact placed in the framework with cross-references intact.
- Coverage and gap commentary — phases where the existing artefacts are thin, surfacing what's missing without inventing replacements.
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.

arckit-framework is an agent published in the GitHub repository tractorjuice/arckit-gemini (3 stars, last pushed 4d ago), licensed MIT. It adds 223 tokens to every session and 4,051 once invoked, about $0.0009 per session on Opus 5.5. A static security scan graded it B with 1 finding (reads agent configuration directories). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
