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 | $0.00312 | $0.00312 |
| Opus 5 | $0.00156 | $0.00156 |
| Sonnet 5 | $0.00062 | $0.00062 |
| Haiku 4.5 | $0.00031 | $0.00031 |
Grade A, and why
agent-assh copilot-instructions.md 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.
What it actually says
Use assh for SSH work so large remote output stays out of the agent context.
Install: npm i -g agent-assh && assh version
Connect:
- With key:
assh connect -H HOST -u USER -i KEY -n NAME - With password:
assh connect -H HOST -u USER -E PASS_ENV -n NAME - Provider block: save to 0600 temp →
assh connect-info --file TMP -n NAME - Picky gateway: add
--force-pty
Session: assh session exec -s SID -- "cmd" then assh session read -s SID --seq N --limit 50
Files: assh transfer put/get/read/list/stat/mkdir/rm/mv/sync
Services: assh session service -s SID --action restart --service nginx
Docker/db/anything else: assh session exec -s SID -- "docker ps" / -- "mysql -e 'SELECT 1' db"
Multi-host: assh fleet exec -H H1 -H H2 -u root -- "cmd"
Scan: assh scan -H HOST -u USER
Security: passwords only through env vars, no --password flag. [REDACTED:type] is intentional — do not retry. dangerous_command_requires_confirmation → ask user before --confirm-danger. transfer read reads remote files over ssh. Never put passwords in arguments.
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.

agent-assh copilot-instructions.md is an instructions file published in the GitHub repository izzzzzi/agent-assh (20 stars, last pushed 24d ago), licensed MIT. It adds 312 tokens to every session, about $0.0016 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.
