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 | $0.00050 | $0.00365 |
| Opus 5 | $0.00025 | $0.00182 |
| Sonnet 5 | $0.00010 | $0.00073 |
| Haiku 4.5 | $0.00005 | $0.00036 |
Grade A, and why
evo-pddl-plan-formatter 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 yesterday.
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
evo-pddl-plan-formatter
Orchestrates solving of all PDDL tasks from problem.json and writes correctly formatted plan output files.
Key Functions
run_all_tasks(problem_json_path, base_dir=None)- Main orchestratorwrite_plan_custom_format(plan_actions, filename)- Write action_name(p1, p2) formatwrite_plan_pddl_format(plan_actions, filename)- Write (action_name p1 p2) formatformat_action_instance(action_name, params)- Format single action
Usage
import sys
sys.path.insert(0, '/app/environment/skills/evo-pddl-plan-formatter/scripts')
from utils import run_all_tasks
results = run_all_tasks('/app/problem.json', base_dir='/app')
Output Format
The verifier expects plans in action_name(param1, param2, ...) format,
one action per line. Example:
move_seg_ppdoor_0_40_seg_tww1_0_200_north_south_medium(airplane_cfbeg)
startup_seg_tww1_0_200_north_medium(airplane_cfbeg)
Dependencies
- evo-pddl-solver (for solve_pddl_task function)
Notes
- unified_planning lowercases all names during parsing
- Plan output paths are relative to base_dir (default: directory of problem.json)
- Empty files are written for failed tasks to avoid file-not-found errors
What ships with it
1 file 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.

evo-pddl-plan-formatter is a skill published in the GitHub repository OpenLAIR/OpenSkill (90 stars, last pushed 2d ago), licensed Apache-2.0. It adds 50 tokens to every session and 365 once invoked, about $0.0003 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 2026-09-11.

flux-analyzer
Analyse FBA flux distributions to extract biological insights. Covers gene essentiality, phenotypic phase planes, flux sampling, pathway-level aggregation, secretion product prediction, and production of publication- quality figures.
experimental-design
Best practices for designing reproducible ML experiments. Use when planning ablations, baselines, or controlled experiments.
prolong
Recover and use durable coding-session history from PRO-LONG's local append-only log. Use on long-running coding tasks, after context compaction or session resume, when reconstructing prior decisions or tool results, or before repeating work that may already have been attempted.
resolving-merge-conflicts
Use when a git merge or rebase reports conflicts and the operation is in progress.
security-review
Use when reviewing code for vulnerabilities, checking diffs for injection/XSS/auth/crypto issues. Invokes on code changes (.go/.py/.js/.ts/.java/.rs/.php/.rb), not docs-only diffs.
script-exec-blocked
Sandbox approval policy blocks executecode and python3 -c; use readfile/writefile + manual transforms instead of retrying both runners.
