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 Excessive Agency · line 4 Skill enables autonomous high-impact decisions without human-in-the-loop verification. Critical operations (destructive commands, financial transactions, data deletion) should require explicit user confirmation.Fix: Add human-in-the-loop confirmation for destructive, irreversible, or high-impact operations. Never auto-execute commands that modify files, send data, or alter system state.
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 | $0.00000 | $0.00316 |
| Opus 5.5 | $0.00000 | $0.00126 |
| Sonnet 5.5 | $0.00000 | $0.00063 |
| Haiku 4.5 | $0.00000 | $0.00032 |
Grade A, and why
quick-capture 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 1mo 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
Skill: quick-capture
Purpose
Route a prefixed message to the right file without asking a follow-up question. Capture has to be frictionless or it does not happen.
Trigger
A message beginning with a known prefix.
Routing
| Prefix | Meaning | Destination |
|---|---|---|
n: |
A note or idea | New file in 00_Start/Inbox/ |
t: |
A task | Append - [ ] <text> #todo to 00_Start/Tasks.md |
q: |
A quote worth keeping | New file in 05_Wisdom/ |
p: |
A person to remember | 40_Network/People/First Last.md |
Outputs
The destination file, with full frontmatter per
99_Assets/Templates/CONVENTIONS.md. Nothing else.
Invariants
- Never ask a clarifying question for a prefixed message. Route it, or flag it.
p:uses every field of the person template; unknown values stay"".- Never write to a file other than the destination.
- Never edit a generated file.
Failure behaviour
An unrecognised prefix, or text that does not fit the prefix it carries: write it to
00_Start/Inbox/ tagged #needs-review, and say in one line what was unclear.
History
Initial version. See chapter 12 for why this is the first skill to build.
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.

quick-capture is a skill published in the GitHub repository bbuch82/agentic-second-brain-guide (89 stars, last pushed 2mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 316 tokens. 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.
