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: 2 findings, up to high
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 →
- high Anti-Refusal · line 157 Skill instructs the agent to omit warnings, disclaimers, or ethical commentary. Stripping safety caveats hides risk from the user and is a common jailbreak preamble.Fix: Remove instructions that suppress warnings, disclaimers, or ethical commentary. Let the agent surface safety-relevant caveats to the user.
- medium Excessive Agency · line 16 Skill selects an external model or provider that may use a different account or billing plan than the operator expects. Undisclosed model switches can cause unexpected cost or quota consumption.Fix: Remove the model/provider override or disclose it prominently and require explicit operator approval before invoking an external coding CLI or billed model.
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 | $0.00122 | $0.03270 |
| Opus 5 | $0.00061 | $0.01635 |
| Sonnet 5 | $0.00024 | $0.00654 |
| Haiku 4.5 | $0.00012 | $0.00327 |
Grade A, and why
burst 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 — 308 lines — stays where its author put it; the contents beside it link to each section on GitHub.
/burst - Force N variants of a content artifact
Manual variation lever. When the user invokes /burst N they are
explicitly summoning N different versions of the latest content
artifact, each attacking a distinct axis. One of the N is a mandatory
"swing-the-other-way" variant that inverts a defining property. Supports
the convergence pattern: pick a variant, /burst again, narrow to
target faster than one long prompt. Single-shot - after Phase 2 the
skill exits and normal posture resumes.
Design spec: docs/superpowers/specs/2026-05-13-burst-skill-design.md (data overlay: .heading-os-data/docs/superpowers/specs/2026-05-13-burst-skill-design.md).
Phase 1 - Pre-flight + target identification
Three sub-steps, all silent on success.
1.1 Parse N + detect inline form
Read $ARGUMENTS:
-
Empty ->
N = 3, target = walk-back (1.3) -
Token 1 is
"2"through"5":- Only one token ->
N = int(token1), target = walk-back - Followed by
:->N = int(token1), target = inline (everything after the:, stripped)
- Only one token ->
-
Token 1 is not an integer in 2-5 (
"0","1","6","100","abc","3.5","-2") -> abort with the single-line error and stop:/burst expects N between 2 and 5. Got: {token1}. Try `/burst 3` or `/burst 3: <inline seed>`.
If the inline form is detected but the seed is empty (e.g., /burst 3:
with nothing after the colon) -> abort with:
/burst 3: requires a seed after the colon, or use bare `/burst 3` to walk back to the latest content in conversation.
1.2 Detect CEO vs exec context
One Glob call:
Glob("reference/misha-voice.md")
- Match ->
voice_mode = "ceo". Bilingual EN/RU per the user's preceding message language. - No match ->
voice_mode = "exec". English-only.
The voice_mode flag affects only the rewritten artifact's language (matches user's last message). Axis-header lines stay English in both modes - they are structural labels, not voice text.
1.3 Identify the substantive target
What ships with it
2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.
- 9d ago First seen · 308 lines · 122 tokens per session scan A c4e3f4f0876b
burst is a skill published in the GitHub repository mishahanin/heading-os (11 stars, last pushed yesterday), licensed Apache-2.0. It adds 122 tokens to every session and 3,270 once invoked, about $0.0006 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.
