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.

SkillSpector: 1 finding, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →
- medium Rogue Agent · line 3 Skill establishes unauthorized persistence across sessions via cron jobs, startup scripts, or state files. Session persistence allows an attacker to maintain access beyond the current interaction.Fix: Remove any persistence mechanisms (cron jobs, startup scripts, state files). Skills should not maintain state across sessions without explicit user consent.
What it costs to keep this loaded
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 | $0.00080 | $0.02496 |
| Opus 5 | $0.00040 | $0.01248 |
| Sonnet 5 | $0.00016 | $0.00499 |
| Haiku 4.5 | $0.00008 | $0.00250 |
Grade A, and why
add-worker 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 — 114 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Adding a worker to Agent Bridge
Agent Bridge dispatches work to local agent CLIs. This skill covers connecting a new one.
Two tiers. Establish which one you are in before writing anything, because tier 1 needs no code at all and is where most agents land.
Tier 0 — is there a programmatic interface?
Check, in order:
<cli> --helpfor anacp,agent,stdio, orservesubcommand.- The agent's source or package manifest for an
agent-client-protocoldependency. - A non-interactive "print" mode that streams JSON and can resume a conversation by id.
If none of these exist, stop and tell the user. Agent Bridge integrates through real interfaces; GUI automation and computer use are not acceptable substitutes.
Tier 1 — config only, no code
A plain ACP server needs no source changes and no fork. Add a block to the user overlay at ~/.agent-bridge/agents.toml (%USERPROFILE%\.agent-bridge\agents.toml on Windows):
[agents.mycustom]
protocol = "acp"
command = ["mycustom-cli", "acp", "--yolo"]
revivable = true
idle_unload_sec = 900
Fields (all optional except protocol and command): fallback_commands (list of alternative argv lists), cwd, env (per-worker overlay), session_meta (extra params for session/new), revivable, idle_unload_sec, stall_timeout_sec, print_timeout.
Verify end to end before doing anything else:
list_agents # the worker appears with available: true
dispatch_task # agent="mycustom", cwd = an absolute scratch folder
wait_task # loop until terminal
get_result # text came back
Tier 1 gets you: spawn and handshake, session/new, prompting, streaming text, tool-call and workspace-diff file tracking, cancel, idle unload, transcripts, and session/load revive when revivable = true. Auto-approval works if the agent uses ACP requestPermission (Bridge picks allow-always) or accepts a yolo flag you put in command.
Go to tier 2 only if one of these is true:
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.

add-worker is a skill published in the GitHub repository FeiZhuLulu/Agent-Bridge (34 stars, last pushed 2d ago), licensed MIT. It adds 80 tokens to every session and 2,496 once invoked, about $0.0004 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.
