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 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 YARA Match · line 107 YARA rule matched a known malware signature (reverse shell, backdoor, ransomware, C2 framework, or info stealer).Fix: Remove the malware payload or compromised file entirely. Investigate how it entered the skill and audit all other artifacts for additional indicators of compromise.
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 | $0.00047 | $0.02010 |
| Opus 5 | $0.00023 | $0.01005 |
| Sonnet 5 | $0.00009 | $0.00402 |
| Haiku 4.5 | $0.00005 | $0.00201 |
Grade A, and why
dynamic-linking 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 3d 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 — 154 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Dynamic linking
Linux loads shared libraries at startup or on demand through ld.so. This skill builds versioned shared objects, places them where the loader finds them, and diagnoses the failures in between.
Contract
| Field | Bound contract |
|---|---|
| Trigger | A build or run fails with cannot open shared object file or symbol lookup error, the task sets RPATH or RUNPATH, versions a library with a soname, writes a dlopen plugin, or interposes a function with LD_PRELOAD. |
| Authority | Reversible local: writes only built .so files, symlinks, source, and the loader cache entries the procedure names (ldconfig needs root); rollback is version control, removing created symlinks, and re-running ldconfig. No remote mutation. |
| Side effect | Local writes to build outputs, symlinks, and /etc/ld.so.cache when ldconfig runs. Environment variables and loader flags stay inside the session. |
| Done | The binary runs against the intended library, proven by ldd resolving every dependency to the intended path and by a clean LD_DEBUG=libs trace or the plugin loading end to end. |
Inputs
- The failing binary or the library to build: required.
- The intended library location: required for search-path work.
- Whether deployment must be relocatable: required before choosing
$ORIGIN, RPATH, or RUNPATH. - Root access: required only when registering a library system-wide with
ldconfig.
Procedure
- Build the shared library with a soname. The soname is what executables record and what
ldconfigmaintains. Done when:readelf -d libmylib.so.1.2.3prints the intendedSONAME.
gcc -fPIC -c src/mylib.c -o mylib.o
gcc -shared -Wl,-soname,libmylib.so.1 mylib.o -o libmylib.so.1.2.3
ln -s libmylib.so.1.2.3 libmylib.so.1 # loader name
ln -s libmylib.so.1 libmylib.so # linker name for -lmylib
- Bump versions by ABI change, not by habit. Done when: the bump class matches the change.
| Bump | When |
|---|---|
| PATCH | Bug fix, ABI unchanged |
| MINOR | Symbols added, backwards compatible: keep the soname, refresh the .so.1 symlink |
| MAJOR | ABI breaks: new soname, old .so.1 files stay installed for existing binaries |
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.

dynamic-linking is a skill published in the GitHub repository OutlineDriven/outline-driven-development (52 stars, last pushed 3d ago), licensed Apache-2.0. It adds 47 tokens to every session and 2,010 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 2026-09-06.
