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: 4 findings, 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 →

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 | $0.00099 | $0.06986 |
| Opus 5 | $0.00049 | $0.03493 |
| Sonnet 5 | $0.00020 | $0.01397 |
| Haiku 4.5 | $0.00010 | $0.00699 |
Grade A, and why
mission-brief 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 12d 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 — 641 lines — stays where its author put it; the contents beside it link to each section on GitHub.
mission-brief
What this skill does
mission-brief takes a feature description, structures it into a Mission
Brief (goal, constraints, success criteria), generates an ordered step
list with prompts, and executes those steps — each step dispatched to a
subagent whose prompt triggers the installed SDD skills. No YAML workflow
files, no per-framework profiles, no profile detection. The step prompts use
canonical SDD terminology (specify, plan, implement, converge) that works with
any SDD skill set — model-invoked skills auto-trigger, command-based
frameworks match by filename, and if neither exists the subagent executes
directly.
When to use
- "Build this feature end to end": you give a description, mission-brief composes the pipeline and runs specify → plan → implement ↔ converge.
- You want a converge loop with a circuit breaker and an audit trail.
- You want to resume an interrupted mission across sessions
(
mission-brief --resume). - You want to run unattended across sessions (
mission-brief --async).
When NOT to use
- A single small edit — just do it; a mission is overhead.
- You already have a spec and tasks and only want to implement one task — invoke the implement skill directly.
Mission Brief template
Before generating steps, the description is structured into:
## Mission Brief
**Goal**: <what to build — one sentence>
**Constraints**: <tech stack, limitations, dependencies, requirements>
**Non-Goals**: <what is explicitly out of scope — e.g., "no database storage, local memory cache only">
**Success Criteria**:
- <measurable outcome 1>
- <measurable outcome 2>
- <measurable outcome 3>
The brief serves two purposes:
- Forces explicit done-criteria upfront — feeds the converge step's independence check (the checker verifies against these criteria).
- Carries mission context into every step's delegation prompt so each subagent has full context without re-reading prior steps.
Inputs
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.

mission-brief is a skill published in the GitHub repository tikalk/adlc-team-skills (133 stars, last pushed today), licensed MIT. It adds 99 tokens to every session and 6,986 once invoked, about $0.0005 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.
