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 | $0.02969 |
| Opus 5 | $0.00021 | $0.01484 |
| Sonnet 5 | $0.00008 | $0.00594 |
| Haiku 4.5 | $0.00004 | $0.00297 |
Grade A, and why
add-specialist 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 9d 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 — 390 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Add Specialist
Register a specialist agent so the Tech Lead considers it during implementation
planning, incident analysis, and retrospectives. Trigger vocabulary for the
specialist lives in the agent's own description field. This skill registers
the agent and optionally adds project-local code-area overrides.
Input
$ARGUMENTS = agent name, optional target type, path-or-slug value, and zero
or more project-local code-area override signals.
Register only (subagent, most common case):
my-security-agent
payments-specialist
data-engineer
Register with explicit target type (flag form):
security-gate --target-type=human "Alice Chen (CISO)"
ops-runbook --target-type=doc docs/ops/incident-response.md
write-runbook-skill --target-type=skill write-runbook
external-analyst --target-type=external-agent plugin-x:analyst-agent
Register with explicit target type (positional form):
security-gate human "Alice Chen (CISO)"
ops-runbook doc docs/ops/incident-response.md
write-runbook-skill skill write-runbook
external-analyst external-agent plugin-x:analyst-agent
Register subagent with project-local overrides:
payments-specialist "src/payments/**" "src/billing/**"
data-engineer "src/etl/**"
Trigger keywords such as authentication or pipeline belong in the agent's
description, not in this argument list. If keyword-style arguments are
provided, a warning is shown (see backward compatibility below).
The five valid target types are: subagent (default), skill, doc,
human, external-agent. Omitting the target type registers a subagent
entry in the legacy format, preserving full backward compatibility.
Process
1. Parse Arguments
Split $ARGUMENTS on whitespace, respecting quoted strings.
- First token = agent name (required).
- Second token = examined to determine whether it is a target-type token
or an override signal:
- If it is one of the five fixed strings (
subagent,skill,doc,human,external-agent), treat it as the target type. The token immediately following it is the path-or-slug value for the registration. - If a
--target-type=<type>flag appears anywhere in$ARGUMENTS, use that value as the target type. The non-flag tokens after the agent name are the path-or-slug value (if any) and override signals. - Otherwise, assume target type
subagentand treat all remaining tokens as override signals (existing behavior).
- If it is one of the five fixed strings (
- Path-or-slug value (required for non-
subagenttarget types):skill: the skill slug (e.g.,write-runbook).doc: the file path (e.g.,docs/security/review-gate.md).human: the contact identifier (name, role, or email address).external-agent: the namespaced slug (e.g.,plugin-x:agent-y).
- Remaining tokens = project-local code-area override signals (file globs or repo-specific keywords). May be empty.
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-specialist is a skill published in the GitHub repository cpliakas/claude-code-engineering-leaders (4 stars, last pushed 17d ago), licensed MIT. It adds 42 tokens to every session and 2,969 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 2026-08-31.
